Background

An example of a conventional button holding structure for a vehicle door is disclosed in japanese patent laid-open No. 2003-227251. The button holding structure is provided in a button insertion hole provided through the door trim. The button holding structure guides the indicator button in ascending and descending of the indicator button inserted into the button insertion hole from below in an upward convex shape.

The button holding structure includes a guide portion and an introduction portion. The guide portion includes a trimming ring inserted into the button insertion hole. The guide portion guides the indicator button up and down by the trimming ring. The introduction portion includes a plurality of ribs formed integrally with the door trim, and is provided below the guide portion. The inner side edge of each rib is inclined toward the trim ring of the guide portion.

When the indicator button is inserted into the button insertion hole, the introduction portion guides the indicator button to the trimming ring of the guide portion through the inner side edges of the ribs.

However, in the above-described conventional button holding structure for a vehicle door, when the indicator button is inserted into the button insertion hole, the inner side edges of the ribs partially press the indicator button, which is a problem in that the indicator button is easily damaged.

Disclosure of Invention

Therefore, it is a non-limiting object of the present invention to provide a button holding structure for a vehicle door that can suppress damage to an indicator button. This object is achieved by way of example of claim 1. Further developments of the present example are described in the dependent claims.

The button holding structure of the present exemplary vehicle door is provided in a button insertion hole provided through a vehicle door trim, and guides an indicator button having an upward convex shape, which is inserted into the button insertion hole from below, when the indicator button ascends and descends, wherein,

the button holding structure of the vehicle door comprises:

a guide part which guides the indicator button up and down; and

an introduction portion provided below the guide portion and guiding the indicator button to the guide portion,

the leading-in portion is including leading-in curved surface, leading-in curved surface is around the axle center of button jack surrounds the curved surface that the indicator button just is the expansion of back taper form downwards.

In the button holding structure of the vehicle door of the present example, when the indicator button is inserted into the button insertion hole, the insertion portion guides the indicator button to the guide portion by introducing the curved surface. At this time, the introduction curved surface is in contact with the indicator button in a planar manner, and therefore, partial pressing of the indicator button can be suppressed.

Therefore, in the button holding structure of the vehicle door of the present example, damage to the indicator button can be suppressed. As a result, in the button holding structure, the reduction in the appearance of the vehicle interior can be suppressed.

In another mode of the present demonstration, it is preferable that the introduction curved surface surrounds the indicator button within a range exceeding 180 ° around the axis. In this case, the curved introduction surface abuts the indicator button so as to have a large surface, and therefore, partial pressing of the indicator button can be further suppressed.

In another aspect of the present invention, it is preferable that the guide portion and the introduction portion are integrally formed in the door trim. In this case, the work of assembling the button holding structure of the door to the door trim can be simplified.

In another aspect of the present invention, it is preferable that the guide portion and the introduction portion are integrally fixed to the door trim. In this case, the operation of assembling the button holding structure of the door to the door trim can be simplified.

Preferably, the button holding structure of the vehicle door of the present example includes: a first member which is formed with a guide portion and an introduction portion and which abuts against the door trim from below; and a second member which abuts against the door trim from above, holds the door trim together with the first member, and covers an outer peripheral edge of the button insertion hole. In this case, the first member and the second member can be simplified, and the shape of the periphery of the button insertion hole in the door trim can be simplified.

In another aspect of the present invention, it is preferable that a plurality of engaging portions are formed on one of the first member and the second member, and the plurality of engaging portions extend toward the other of the first member and the second member along the axial center and are elastically deformable in a radial inner direction of the axial center. Preferably, a claw is formed at a distal end of each of the engaging portions, the claw protruding radially outward of the axial center and engaging with the other of the first member and the second member to restrict separation of the first member from the second member. Preferably, the indicator button inserted into the button insertion hole restricts elastic deformation of each engaging portion in the radial inward direction. In this case, since the plurality of engaging portions are restricted by the indicator button and the claw is less likely to be disengaged, the state in which the first member and the second member sandwich the door trim can be reliably maintained.

In another aspect of the present invention, it is preferable that the door trim is formed with a first recess and a second recess each recessed radially outward of the axial center from an outer peripheral edge of the button insertion hole. Preferably, the first recess and the second recess are point-asymmetrical with respect to each other about the axial center. Preferably, the second member has a first convex portion fitted into the first concave portion and a second convex portion fitted into the second concave portion. Preferably, one of the first member and the second member is formed with a third projection projecting toward the other of the first member and the second member along the axial center. Preferably, the other of the first member and the second member has a third concave portion into which the third convex portion is fitted. In this case, even when the shape of the second member is different between the case of using the second member for the left door and the case of using the second member for the right door, the erroneous assembly can be suppressed by fitting the first to third concave portions and the first to third convex portions.

In another aspect of the present invention, it is preferable that the guide portion includes a pressing piece that extends along the axial center, abuts against the indicator button, and is elastically deformable in a radial direction outward of the axial center. In this case, the guide portion can smoothly guide the indicator button while suppressing the rattling of the indicator button by the pressing piece.

On the other hand, when the locking/unlocking mechanism of the vehicle lock device 90 is switched to the locked state, the not-shown link is interlocked to pull down the indicator lever 7A. Thereby, the indicator button 7 is guided by the button holding structure 1 and lowered to the lock display position P2 shown in fig. 2. As a result, the user can easily recognize that the door 8 is locked by visually observing the indicator button 7 through the window of the door 8 from the outside of the vehicle (P2).

< specific construction of button holding Structure >

As shown in fig. 4, 5, and 7, the button holding structure 1 includes a holder 10 and a bezel 20. The retainer 10 is an example of the "first member" of this example. The bezel 20 is an example of the "second member" of this example.

The holder 10 and the frame 20 are each a resin molded product manufactured by injection molding or the like of a thermoplastic resin. In the present embodiment, the resin material of the holder 10 is different from the resin material of the frame 20. Specifically, the bezel 20 is made of a resin material that can form a high-quality surface because the appearance is required to be higher than the holder 10.

As shown in fig. 4 and 5, a first recess 81 and a second recess 82 for positioning the bezel 20 with respect to the door trim 80 are formed in the upper wall portion 80U of the door trim 80.

The first recess 81 is a substantially rectangular recess located on the vehicle outer side with respect to the axis X1 and recessed radially outward of the axis X1 from the outer peripheral edge of the button insertion hole 87. The second recess 82 is a substantially rectangular recess that is located on the vehicle inner side with respect to the axis X1, is located forward of the first recess 81 in the front-rear direction, and is recessed radially outward from the outer peripheral edge of the button insertion hole 87 with respect to the axis X1. That is, the first concave portion 81 and the second concave portion 82 are not point-symmetrical about the axial center X1.

As shown in fig. 5, four abutment convex portions 88 for determining the posture of the retainer 10 when it abuts against the door trim 80 are formed on the lower surface of the upper wall portion 80U of the door trim 80.

Each of the abutment projections 88 is a substantially cylindrical shape as follows: two portions of the upper wall portion 80U of the door trim 80 that are forward of the axis X1 and adjacent to the outer peripheral edge of the button insertion hole 87, and two portions of the upper wall portion 80U of the door trim 80 that are rearward of the axis X1 and adjacent to the outer peripheral edge of the button insertion hole 87, respectively, protrude downward and are short.

As shown in fig. 4, 5, and 7, the holder 10 includes: a cylindrical portion centered on an axis X1; and a funnel-shaped portion which is connected to a lower end of the cylindrical portion, extends downward, and expands radially outward of the axial center X1.

As shown in fig. 4, the upper end surface 10U of the cylindrical portion of the holder 10 is an annular surface that is inclined along the inclination of the upper wall portion 80U of the door trim 80 and surrounds the axial center X1. The holder 10 has an upper end surface 10U formed with a third concave portion 13 and four abutment convex portions 18.

The third recessed portion 13 is a recessed portion that is recessed downward from a portion of the upper end surface 10U of the retainer 10 that is located on the vehicle outer side with respect to the axial center X1.

Each of the abutment convex portions 18 is a substantially cylindrical shape as follows: two portions of the upper end surface 10U of the holder 10 located forward of the axis X1 and two portions of the upper end surface 10U located rearward of the axis X1 are arranged so as to protrude upward short. Each of the abutment convex portions 18 is provided to match each of the abutment convex portions 88 of the door trim 80.

As shown in fig. 4, 6, and 7, two engaged portions 15 are formed in the cylindrical portion of the holder 10. Each of the engaged portions 15 is a stepped portion formed in two grooves extending in the vertical direction and located forward and rearward with respect to the axial center X1 on the inner peripheral side of the cylindrical portion of the holder 10.

As shown in fig. 4 and 6, a guide portion 30 is formed in the cylindrical portion of the holder 10. The guide portion 30 includes two guide protrusions 32 and a pressing piece 31.

The guide projections 32 are disposed on the upper end edges of the portions of the inner peripheral surface of the cylindrical portion of the holder 10 located on the vehicle outer side with respect to the axial center X1, and are separated from each other in the front-rear direction. Each guide projection 32 projects radially inward of the axial center X1.

As shown in fig. 5, the pressing piece 31 has a cantilever shape extending upward along the axial center X1 from the lower end edge of the portion of the inner peripheral surface of the cylindrical portion of the holder 10 located on the vehicle inner side with respect to the axial center X1. The upper end of the pressing piece 31 is bent inward in the radial direction of the axis X1. The pressing piece 31 is elastically deformable so as to displace the upper end portion thereof radially outward of the axial center X1.

As shown in fig. 6, each guide projection 32 and the pressing piece 31 abut against the outer peripheral surface of the indicator button 7 at three locations surrounding the axial center X1.

As shown in fig. 3 and 5 to 7, an introduction portion 40 is formed in the funnel-shaped portion of the holder 10. That is, the introduction portion 40 is provided below the guide portion 30.

The introduction portion 40 includes an introduction curved surface 40A connected to the inner peripheral surface of the cylindrical portion of the holder 10. The insertion curved surface 40A is a curved surface that surrounds the indicator button 7 around the axial center X1 of the button insertion hole 87 and extends downward in an inverted conical shape.

In the present embodiment, the lead-in curved surface 40A surrounds the indicator button 7 in a range exceeding 180 ° around the axis X1. More specifically, the introduction curved surface 40A is a substantially annular curved surface centered on the axis X1, and surrounds the entire circumference of the indicator button 7.

As shown in fig. 4, 5, and 7, the bezel 20 includes a frame-shaped portion having a circular hole 27 formed at the center thereof and centered on the axial center X1. The frame-shaped portion of the bezel 20 is set to a size that covers the outer peripheral edge of the button insertion hole 87 and the first and second concave portions 81 and 82.

As shown in fig. 7, the inner diameter of the circular hole 27 is set larger than the outer diameter of the indicator button 7 so as not to contact the outer peripheral surface of the indicator button 7.

As shown in fig. 5, a first projection 21, a second projection 22, a third projection 23, and two engaging portions 25 are formed on the lower surface of the frame-shaped portion of the bezel 20.

The first projection 21 projects from a portion of the frame-shaped portion of the bezel 20 located on the vehicle outer side with respect to the axial center X1. The first convex portion 21 can be fitted to the first concave portion 81 of the door trim 80.

The second convex portion 22 is provided to protrude from a portion of the frame-shaped portion of the bezel 20 that is located on the vehicle inner side with respect to the axis X1 and is located forward of the first convex portion 21 in the front-rear direction. The second convex portion 22 can be fitted to the second concave portion 82 of the door trim 80.

The third projection 23 projects downward from the front end edge of the lower surface of the first projection 21 along the axial center X1 so as to approach the holder 10. The third convex portion 23 can be fitted to the third concave portion 13 of the holder 10.

The two engaging portions 25 are cantilevered beams extending downward from two positions of the frame-shaped portion of the bezel 20, which are forward and rearward of the axis X1 and adjacent to the outer periphery of the circular hole 27, respectively, along the axis X1 so as to approach the holder 10.

A claw 25A is formed at the tip of each engaging portion 25. The claw 25A of each engaging portion 25 projects radially outward of the axial center X1, and is engageable with each engaged portion 15 of the holder 10. Each engaging portion 25 is elastically deformable so as to displace the claw 25A in the radial direction of the axial center X1.

< Structure for holding Press button and method for assembling indicator Press button >

The button holding structure 1 having the above-described structure is assembled to the door trim 80 as follows.

That is, as shown in fig. 4 and 5, the bezel 20 is lowered toward the button insertion hole 87 from a position above the upper wall portion 80U of the door trim 80. At this time, the engaging portions 25 pass through the button insertion holes 87 while elastically deforming in the radial inner direction of the axial center X1 by bringing the claws 25A into sliding contact with the inner peripheral surfaces of the button insertion holes 87.

The first convex portion 21 is fitted into the first concave portion 81, and the second convex portion 22 is fitted into the second concave portion 82, whereby the bezel 20 is positioned with respect to the door trim 80. As a result, the frame-shaped portion of the bezel 20 abuts the upper wall portion 80U of the door trim 80 from above and covers the outer peripheral edge of the button insertion hole 87.

Next, the retainer 10 is raised from a position below the upper wall portion 80U of the door trim 80 toward the button insertion hole 87. At this time, the third convex portion 23 of the bezel 20 is fitted into the third concave portion 13 of the holder 10. Further, each engaging portion 25 of the bezel 20 enters the inner circumferential side of the cylindrical portion of the holder 10.

Each engaging portion 25 is elastically deformed in the radial direction of the axial center X1 by bringing the claw 25A into sliding contact with each engaged portion 15, and is not elastically deformed after the claw 25A passes over each engaged portion 15. As a result, as shown in fig. 7, the claws 25A of the engaging portions 25 engage with the engaged portions 15, and the holder 10 is restricted from being separated from the bezel 20. As a result, the holder 10 and the bezel 20 sandwich the door trim 80.

In this state, the elastic foam layer 80B of the door trim 80 is pressed by the frame-shaped portion of the bezel 20 to be slightly recessed, thereby exerting a restoring force. By this restoring force, the claws 25A of the engaging portions 25 engage with the engaged portions 15 without rattling, and therefore, generation of abnormal noise can be suppressed.

In this state, the respective contact convex portions 18 of the holder 10 shown in fig. 4 contact the respective contact convex portions 88 of the door trim 80 shown in fig. 5 from below, thereby determining the posture of the holder 10 when contacting the door trim 80.

As shown in fig. 3, after the button holding structure 1 is assembled to the door trim 80, the indicator button 7 is inserted into the button insertion hole 87. At this time, the introduction portion 40 smoothly guides the indicator button 7 to the guide portion 30 by the introduction curved surface 40A which is expanded downward in an inverted cone shape. As a result, as shown in fig. 2 and 7, the button holding structure 1 holds the indicator button 7 in a state in which the upper end of the indicator button 7 is positioned above the frame-shaped portion of the bezel 20.

As shown in fig. 6, in this state, the guide projections 32 and the pressing pieces 31 of the guide portion 30 contact the outer peripheral surface of the indicator button 7 at three locations surrounding the axial center X1, thereby guiding the indicator button 7 up and down. When the indicator button 7 is shaken or tilted with respect to the axial center X1, the pressing piece 31 is elastically deformed in the radial outward direction of the axial center X1 and applies an appropriate pressing force to the indicator button 7. This maintains the state in which the guide projections 32 and the pressing pieces 31 are in contact with the outer peripheral surface of the indicator button 7.

As shown in fig. 7, the indicator button 7 inserted into the button insertion hole 87 restricts the elastic deformation of each engaging portion 25 in the radial direction of the axial center X1. As a result, the claws 25A of the engaging portions 25 are less likely to be disengaged from the engaged portions 15.

When the button holding structure 1 is applied to the door 8, which is the right side door, the holder 10 is not changed, but the positional relationship among the button insertion hole 87, the first recess 81, and the second recess 82 of the door trim 80 is the same as the mirror image of the above-described structure, and the bezel 20 is also the same as the mirror image of the above-described structure.

< Effect >

In the button holding structure 1 of embodiment 1, as shown in fig. 3, when the indicator button 7 is inserted into the button insertion hole 87, the introduction portion 40 guides the indicator button 7 to the guide portion 30 by the introduction curved surface 40A. At this time, the introduction curved surface 40A is in surface contact with the indicator button 7, and therefore, partial pressing of the indicator button 7 can be suppressed.

Therefore, in the button holding structure 1 of embodiment 1, damage to the indicator button 7 can be suppressed. As a result, in the button holding structure 1, the reduction in the appearance of the vehicle interior can be suppressed.

In addition, in the button holding structure 1, the introduction curved surface 40A surrounds the indicator button 7 in a range exceeding 180 ° around the axis X1. More specifically, the introduction curved surface 40A is a substantially annular curved surface centered on the axis X1, and surrounds the entire circumference of the indicator button 7. With this configuration, the introduction curved surface 40A abuts against the indicator button 7 with a large surface, and therefore, partial pressing of the indicator button 7 can be further suppressed.

As shown in fig. 4 and 5, in the button holding structure 1, the guide portion 30 and the introduction portion 40 are formed in the holder 10 that is in contact with the door trim 80 from below, and the bezel 20 that is in contact with the door trim 80 from above sandwiches the door trim 80 together with the holder 10 and covers the outer peripheral edge of the button insertion hole 87. With this configuration, the retainer 10 and the bezel 20 can be simplified, and the shape of the periphery of the button insertion hole 87 of the door trim 80 can be simplified.

In the button holding structure 1, as shown in fig. 7, the indicator button 7 inserted into the button insertion hole 87 restricts the elastic deformation of each engaging portion 25 of the bezel 20 in the radial direction of the axial center X1. With this configuration, the claws 25A of the engaging portions 25 are less likely to be disengaged from the engaged portions 15 of the holder 10, and therefore the state in which the door trim 80 is sandwiched between the holder 10 and the bezel 20 can be reliably maintained.

In the button holding structure 1, as shown in fig. 4 and 5, in the door trim 80, the first concave portion 81 and the second concave portion 82 are not point-symmetrical about the axial center X1. The frame 20 is formed with a first convex portion 21 fitted to the first concave portion 81, a second convex portion 22 fitted to the second concave portion 82, and a third convex portion 23 fitted to the third concave portion 13 of the holder 10. With this configuration, even when the shape of the frame 20 is different between the door 8 for the left side door and the door 8 for the right side door, erroneous assembly can be suppressed by fitting the first to third concave portions 81, 82, and 13 to the first to third convex portions 21, 22, and 23.

In the push button holding structure 1, as shown in fig. 4 to 6, the guide portion 30 includes the pressing piece 31 extending along the axial center X1, abutting the indicator push button 7, and elastically deformable in the radial outward direction of the axial center X1. With this configuration, when the indicator button 7 guided vertically by the guide section 30 is shaken or inclined with respect to the axis X1, the pressing piece 31 is elastically deformed in the radial outward direction of the axis X1 and applies an appropriate pressing force to the indicator button 7. This maintains the state in which the guide projections 32 and the pressing pieces 31 are in contact with the outer peripheral surface of the indicator button 7. As a result, the guide portion 30 can smoothly guide the indicator button 7 while suppressing the rattling of the indicator button 7.

(example 2)

As shown in fig. 8 to 10, the button holding structure 2 of embodiment 2 employs the guide portion 230 and the introduction portion 240 integrally formed on the door trim 80 instead of the holder 10 of the button holding structure 1 of embodiment 1, and employs the bezel 20 of embodiment 1 as it is.

The other structure of embodiment 2 is the same as embodiment 1. Therefore, the same components as those in embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted or simplified.

As shown in fig. 8, in the button holding structure 2, the door trim 80 includes a cylindrical portion extending downward from the lower surface of the upper wall portion 80U centering on the axial center X1.

As shown in fig. 9 and 10, the button insertion hole 87, the first concave portion 81, and the second concave portion 82 are surrounded by the cylindrical portion of the door trim 80 and extend to a position lower than that of embodiment 1.

As shown in fig. 8 and 10, two engaged portions 285 are formed in the cylindrical portion of the door trim 80. Each engaged portion 285 is a stepped portion formed at a front and rear position with respect to the axial center X1 on the inner peripheral side of the cylindrical portion of the door trim 80.

As shown in fig. 8 and 9, a guide portion 230 is formed in the cylindrical portion of the door trim 80. The guide part 230 includes two guide protrusions 232 and a pressing piece 231.

Each guide projection 232 is disposed on an inner flange portion 287A having a diameter smaller than the diameter of the button insertion hole 87 on the inner peripheral side of the cylindrical portion of the door trim 80. The guide projections 232 are located on the vehicle outer side with respect to the shaft center X1 and are separated from each other in the front-rear direction. Each guide projection 232 projects radially inward of the axial center X1.

The pressing piece 231 is formed in a cantilever shape extending upward along the axis X1 from a portion located on the vehicle inner side with respect to the axis X1 on the inner peripheral side of the cylindrical portion of the door trim 80. The upper end of the pressing piece 231 is bent inward in the radial direction of the axial center X1. The pressing piece 231 can be elastically deformed so as to displace its upper end portion in the radial direction of the axial center X1.

Each guide projection 232 and the pressing piece 231 abut against the outer peripheral surface of the indicator button 7 at three locations surrounding the axial center X1.

As shown in fig. 8 and 10, an introduction portion 240 is formed in the cylindrical portion of the door trim 80 below the guide portion 230.

The introduction portion 240 includes a introduction curved surface 240A connected to a lower end edge of the inner flange portion 287A. The introduction curved surface 240A is a curved surface which surrounds the indicator button 7 around the axial center X1 of the button insertion hole 87 and is extended downward in an inverted conical shape.

In the present embodiment, the lead-in curved surface 240A surrounds the indicator button 7 in a range exceeding 180 ° around the axis X1. More specifically, the introduction curved surface 240A is a substantially annular curved surface centered on the axis X1, and surrounds the entire circumference of the indicator button 7.

The bezel 20 is assembled to the door trim 80 as follows. That is, as shown in fig. 8, the bezel 20 is lowered from a position above the upper wall portion 80U of the door trim 80 toward the button insertion hole 87. At this time, each engaging portion 25 is elastically deformed in the radial inner direction of the axial center X1 by bringing the claw 25A into sliding contact with the inner peripheral surface of the button insertion hole 87, and is not elastically deformed after passing through the button insertion hole 87. Thereby, as shown in fig. 10, the claws 25A of the engaging portions 25 engage with the engaged portions 285, and the bezel 20 is restricted from being separated from the door trim 80.

The first convex portion 21 is fitted into the first concave portion 81, and the second convex portion 22 is fitted into the second concave portion 82, whereby the bezel 20 is positioned with respect to the door trim 80. As a result, the frame-shaped portion of the bezel 20 abuts the upper wall portion 80U of the door trim 80 from above and covers the outer peripheral edge of the button insertion hole 87.

In this state, the elastic foam layer 80B of the door trim 80 is pressed by the frame-shaped portion of the bezel 20 to be slightly recessed, thereby exerting a restoring force. Due to this restoring force, the claws 25A of the engaging portions 25 are engaged with the engaged portions 285 without rattling, and therefore, the generation of abnormal noise can be suppressed.

In the button holding structure 2 of embodiment 2 configured as described above, damage to the indicator button 7 can be suppressed by introducing the curved surface 240A, as in the button holding structure 1 of embodiment 1. As a result, in the button holding structure 2, the reduction in the appearance of the vehicle interior can be suppressed.

In the button holding structure 2, the guide portion 230 and the introduction portion 240 are integrally formed in the door trim 80. With this configuration, the work of assembling the button holding structure 2 to the door trim 80 can be simplified.

(example 3)

As shown in fig. 11 to 13, in the button holding structure 3 of example 3, instead of the door trim 80 of the button holding structure 1 of example 1, a door trim 380 having a single-layer structure of a hard resin is used, the holder 10 of example 1 is used as it is, and the bezel 20 of example 1 is removed.

The other structure of embodiment 3 is the same as embodiment 1. Therefore, the same components as those in embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted or simplified.

A button insertion hole 387 centering on the shaft center X1 is provided through the upper wall portion 380U of the door trim 380. The inner diameter of the button insertion hole 387 is set to be substantially equal to the inner diameter of the circular hole 27 of the frame 20 of embodiment 1.

As shown in fig. 12, a third convex portion 383 for determining a posture when the retainer 10 abuts against the door trim 380, and four abutment convex portions 388 are formed on a lower surface of the upper wall portion 380U of the door trim 380.

The third protrusion 383 is disposed on the vehicle outer side of the shaft center X1 of the upper wall portion 380U of the door trim 380 and adjacent to the outer peripheral edge of the button insertion hole 387, and protrudes downward along the shaft center X1 so as to approach the holder 10. The third protrusion 383 can be fitted into the third recess 13 of the holder 10.

The respective abutment convex portions 388 are disposed at two positions of the upper wall portion 380U of the door trim 380, which are forward of the axial center X1 and adjacent to the outer peripheral edge of the button insertion hole 387, and at two positions of the upper wall portion 380U of the door trim 380, which are rearward of the axial center X1 and adjacent to the outer peripheral edge of the button insertion hole 387, and project short downward. Each abutment projection 388 is provided to match each abutment projection 18 of the holder 10.

Two engagement portions 385 are formed on the lower surface of the upper wall portion 380U of the door trim 380. Each of the engagement portions 385 has a cantilever shape extending downward from two portions of the upper wall portion 380U of the door trim 380, which are forward and rearward of the axis X1 and adjacent to the outer peripheral edge of the button insertion hole 387, along the axis X1 so as to approach the holder 10.

A claw 385A is formed at the tip of each engagement portion 385. The claw 385A of each engaging portion 385 protrudes radially outward from the axial center X1, and can be engaged with each engaged portion 15 of the holder 10. Each engagement portion 385 can be elastically deformed so as to displace the claw 385A in the radial direction of the axial center X1.

The retainer 10 is assembled to the door trim 380 as follows. That is, as shown in fig. 11, the retainer 10 is raised toward the button insertion hole 387 from a position below the upper wall portion 380U of the door trim 380. At this time, the third convex portion 383 of the door trim 380 fits into the third concave portion 13 of the holder 10. Further, each engagement portion 385 of the door trim 380 enters the inner peripheral side of the cylindrical portion of the holder 10.

Each engaging portion 385 is elastically deformed in the radial direction of the axial center X1 by bringing the claw 385A into sliding contact with each engaged portion 15, and is not elastically deformed after the claw 385A passes each engaged portion 15. Thereby, as shown in fig. 13, the claws 385A of the respective engagement portions 385 engage with the respective engaged portions 15, and the retainer 10 is restricted from being separated from the door trim 380.

In this state, the respective abutment convex portions 18 of the retainer 10 shown in fig. 11 abut against the respective abutment convex portions 388 of the door trim 380 shown in fig. 12 from below, thereby determining the posture of the retainer 10 when abutting against the door trim 380. As a result, the retainer 10 is firmly fixed to the door trim 380.

In the button holding structure 3 of embodiment 3 having the above configuration, damage to the indicator button 7 can be suppressed by introducing the curved surface 40A, as in the button holding structures 1 and 2 of embodiments 1 and 2. As a result, in the button holding structure 3, the reduction in the appearance of the vehicle interior can be suppressed.

In the button holding structure 3, the holder 10 having the guide portion 30 and the introduction portion 40 formed thereon is integrally fixed to the door trim 380. With this configuration, the operation of assembling the button holding structure 3 of the door 8 to the door trim 380 can be simplified.

The present example has been described above with reference to embodiments 1 to 3, but the present example is not limited to the above-described embodiments 1 to 3, and can be applied with appropriate modifications without departing from the scope of the invention.

In embodiments 1 to 3, the introduction curved surfaces 40A and 240A are substantially annular curved surfaces centered on the axis X1 and surround the entire circumference of the indicator button 7, but the present embodiment is not limited to this configuration. For example, a configuration in which the introduction curved surfaces 40A and 240A are divided into two or more in the circumferential direction of the axis X1 is also included in the present example. In this case, the edges in the circumferential direction of the axial center X1 in the divided portions of the introduction curved surfaces 40A and 240A are preferably rounded, and the gap between the divided portions is preferably also narrowed. The introduction curved surface may be a substantially polygonal ring-shaped curved surface surrounding the axial center X1. Fig. 14 shows a button holding structure according to a modification. In this modification, the retainer 10 of the push button holding structure 1 of embodiment 1 is modified such that the introduction portion 40 includes an introduction curved surface 40C that is a substantially C-shaped curved surface by cutting a part of a portion located on the vehicle outer side of the axial center X1. One end edge and the other end edge of the introduction curved surface 40C in the circumferential direction of the axial center X1 are rounded. Thereby, the curved introduction surface 40C surrounds the indicator button 7 in a range exceeding 180 ° around the axis X1. As a result, in this modification, as in the button holding structures 1 to 3 of embodiments 1 to 3, damage to the indicator button 7 can be suppressed by introducing the curved surface 40C.

In embodiments 1 to 3, the button holding structures 1 to 3 are applied to the door 8 provided on the left side surface of the vehicle, but the present invention is not limited to this structure. For example, the door to which the button holding structure is applied may be a side door provided on the right side surface of the vehicle, or may be a door different from the side door, such as a back door, as long as an indicator button is provided.

The retainer 10 may be formed with an engaging portion that protrudes upward and has the same shape as the two engaging portions 25 of example 1, and the bezel 20 may be formed with an engaged portion that has the same shape as the two engaged portions 15 of example 1 and is opposite thereto, and the retainer 10 and the bezel 20 may sandwich the door trim 80 by engagement of both portions.

A third convex portion having the same shape as the third convex portion 23 of example 1 and protruding upward may be formed on the holder 10, and a third concave portion having the same shape as the third concave portion 13 of example 1 and recessed in the opposite direction may be formed on the frame 20, and both may be fitted.

The indicator button 7 according to embodiments 1 to 3 may be configured such that the locking/unlocking mechanism of the latch device 90 is switched to the locked state by being pressed down to the locking display position P2 by the manual locking operation of the indicator button 7 by the user, and the locking/unlocking mechanism of the latch device 90 is switched to the unlocked state by being pulled up to the unlocking display position P1 by the manual unlocking operation of the indicator button 7 by the user.

A structure in which the frame 20 is removed from embodiment 2 is also included in the present example. In this case, the first concave portion 81 and the second concave portion 82 of embodiment 2 may be eliminated, and the inner diameter of the button insertion hole 87 may be changed to a size substantially equal to the circular hole 27 of the bezel 20.
