Further, the holder member 30 has a plate portion 39 inside thereof, the plate portion 39 opens a coil arrangement hole 391 including a long circular through hole in the first direction Z, and the coil 31 is arranged inside the coil arrangement hole 391.

The holder side plate 34 is disposed to overlap the first case side plate 212 of the first case member 21 and the second case side plate 222 of the second case member 22. The first end 341 of the holder side plate 34 on one side Z1 in the first direction Z has a first convex portion 332 that engages with the first housing cover plate 211. The first protrusions 332 are provided at both ends of the first end 341 extending in the third direction Y, and are fitted into the first housing notches 213 of the first housing member 21 to regulate the movement of the first housing member 21 in the third direction Y. The second end 342 of the other side Z2 of the holder side plate 34 in the first direction Z has a second convex portion 334 that engages with the second case cover plate 221. The second convex portion 334 is provided at both ends of the second end portion 342 extending in the third direction Y, and is fitted into the second case notch 223 of the second case member 22 to restrict the movement of the second case member 22 in the third direction Y. The height H1 of the first protrusion 332 in the first direction Z is preferably equal to or greater than the thickness T1 of the first housing cover 211, and the height H2 of the second protrusion 334 in the first direction Z is preferably equal to or greater than the thickness T2 of the second housing cover 221.

The holder side plate portion 34 has third convex portions 335 protruding in the second direction X, and the third convex portions 335 are provided at both ends of the holder side plate portion 34 extending in the third direction Y. The third convex portion 335 extends in a columnar shape in the first direction Z, the first convex portion 332 is formed by an end portion of one side Z1 of the third convex portion 335 in the first direction Z, and the second convex portion 334 is formed by an end portion of the other side Z2 of the third convex portion 335 in the first direction Z. The third protruding portion 335 engages with an end surface of the first case side plate portion 212 and an end surface of the second case side plate portion 222 in the third direction Y, and restricts movement of the first case side plate portion 212 and the second case side plate portion 222 in the third direction Y.

The outer surface of the holder side plate 34 is provided with a first locking projection 37 for locking the first case side plate 212 of the first case member 21 and a second locking projection 38 for locking the second case side plate 222 of the second case member 22.

Fig. 7(a) and 7(B) show the first locking projection 37, and fig. 8(a) and 8(B) show the second locking projection 38. As shown in fig. 7(a) and 7(B), the first locking projection 37 has a locking surface 371 parallel to the XY plane on the other side Z2 in the first direction Z, and has an inclined surface 372 on one side Z1 in the first direction Z, the inclined surface 372 being inclined to the other side Z2 in the first direction Z toward the outside in the second direction X. On the other hand, as shown in fig. 8(a) and 8(B), the second locking projection 38 has an inclined surface 382 on the other side Z2 in the first direction Z, the inclined surface 382 being inclined to the one side Z1 in the first direction Z toward the outside in the second direction X, and the locking surface 381 parallel to the XY plane is provided on the one side Z1 in the first direction Z.

Therefore, as shown in fig. 9(a), when the first case member 21 is slid from one side Z1 to the other side Z2 in the first direction Z to cover the holder member 30, the end of the other side Z2 of the first case side plate portion 212 abuts against the inclined surface 372 of the first locking projection 37 and slides along the inclined surface 372, thereby spreading in the second direction X. When the first case member 21 is pushed to the other side Z2 in the first direction Z in this state, the first locking protrusion 37 is fitted into the first locking hole 23 of the first case member 21, and the locking surface 371 of the first locking protrusion 37 is locked in the first locking hole 23, so that the first case member 21 is attached to the holder member 30.

Similarly, as shown in fig. 9(B), when the second case member 22 is slid from the other side Z2 to the one side Z1 in the first direction Z to cover the holder member 30, the end of the one side Z1 of the second case side plate portion 222 abuts against the inclined surface 382 of the second locking protrusion 38 and slides along the inclined surface 382, thereby spreading in the second direction X. When the second case member 22 is pushed to the side Z1 in the first direction Z in this state, the second locking projection 38 is fitted into the second locking hole 24 of the second case member 22, and the locking surface 381 of the second locking projection 38 is locked in the second locking hole 24, whereby the second case member 22 is attached to the holder member 30.

At least a part of the second case side plate 222 is covered with the first case side plate 212 when viewed in the second direction X, and in this example, the concave edge 225 of the second case side plate 222 is covered with the convex edge 215 of the first case side plate 212 (see fig. 3). The second locking projection 38 is provided at a position closer to the other side Z2 than the end of the other side Z2 of the first case side plate 212 in the first direction Z, and when the second case member 22 is attached to the holder member 30 in a state where the first case member 21 is attached to the holder member 30, the end of the one side Z1 of the second case side plate 222 in the first direction Z is expanded in the second direction X by the inclined surface 382 of the second locking projection 38, thereby avoiding contact with the end of the other side Z2 of the first case side plate 212.

(Structure of magnetic drive Circuit 40)

Fig. 6 is a perspective view of the magnetic drive circuit 40. As shown in fig. 2, 5 and 6, the magnetic drive circuit 40 has an air-core coil 31 wound in an oblong shape, and a coil wire 311 of the coil 31 is connected to the power supply substrate 32 of the holder member 30 (see fig. 3). A first plate 471 is provided on one side Z1 of the coil 31 in the first direction Z, and a second plate 472 (not shown in fig. 6) is provided on the other side Z2 of the coil 31 in the first direction Z.

When power is supplied to the coil 31 from the outside (higher-order apparatus) via the power supply board 32, the movable body 12 is reciprocated in the second direction X along the plate portion 39 of the holder member 30 inside the support body 11 by the magnetic drive circuit 40, and the magnetic drive circuit 40 includes the coil 31, the first permanent magnet 411, and the second permanent magnet 412. Thereby, a user holding the actuator 10 can obtain information by vibration from the actuator 10.

(action and Effect)

In the actuator 10, the movable body 12 and the support body 11 are in contact with the damper 13 at positions facing each other, and the damper 13 has elasticity or viscoelasticity. Therefore, the occurrence of resonance in the movable body 12 can be suppressed. Further, a magnetic drive circuit 40 is provided, and the magnetic drive circuit 40 is configured to generate vibration in a second direction X intersecting the first direction Z with respect to the movable body 12 with respect to the support body 11. Thereby, the movable body 12 vibrates in the second direction X with respect to the support 11. The support body 11 includes a first case member 21 and a second case member 22 that cover and are locked to the holder member 30, the holder member 30 holds the coil 31, the first case member 21 includes a first case cover portion 211 and a first case side plate portion 212, one side Z1 of the first case cover portion 211 in the first direction Z covers the holder member 30, the first case side plate portion 212 is provided extending from the first case cover portion 211 and covers the holder member 30 on both sides in the second direction X, the second case member 22 includes a second case cover portion 221 and a second case side plate portion 222, the other side Z2 of the second case cover portion 221 in the first direction Z covers the holder member 30, the second case side plate portion 222 is provided extending from the second case cover portion 221 and covers the holder member 30 on both sides in the second direction X. The holder member 30 has the holder side plate 34 overlapping the first case side plate 212 and the second case side plate 222, the first end 341 of one side Z1 of the holder side plate 34 in the first direction Z has the first protrusion 332, the second end 342 of the other side Z2 in the first direction Z has the second protrusion 334, the first case cover plate 211 is locked to the first protrusion 332, and the second case cover plate 221 is locked to the second protrusion 334, so that the support body 11 can be reliably prevented from falling off from the case 20 even if the first case side plate 212 or the second case side plate 222 is opened.

In the actuator 10, the first housing cover 211 of the first housing member 21 has the first housing notch 213 fitted with the first protrusion 332, and the second housing cover 221 of the second housing member 22 has the second housing notch 223 fitted with the second protrusion 334. Therefore, the first and second convex portions 332 and 334 can be prevented from protruding from the housing 20 or prevented from protruding from the housing 20, and therefore the appearance of the actuator 10 is not spoiled.

In the actuator 10, the height of the first protrusion 332 is equal to or greater than the thickness of the first housing cover 211 of the first housing member 21, and the height of the second protrusion 334 is equal to or greater than the thickness of the second housing cover 221. Therefore, even if the first housing cover 211 or the second housing cover 221 is slightly deformed, the first protrusion 332 and the second protrusion 334 are engaged with each other, so that the first housing cover 211 and the second housing cover 221 can be reliably engaged with each other, and the support 11 can be reliably prevented from falling off the housing 20.

In the actuator 10, the holder-side plate portion 34 has the third projecting portion 335 projecting in the second direction X, and the third projecting portion 335 extends in a columnar shape on both sides in the first direction Z so as to form the first projecting portion 332 and the second projecting portion 334, and engages with the end surface of the first housing-side plate portion 212 and the end surface of the second housing-side plate portion 222 in the third direction Y, so that the support body 11 can be more reliably prevented from coming off the housing 20.

In the actuator 10, the first locking protrusion 37 is fitted into and locked to the first locking hole 23, the first locking protrusion 37 is provided on the outer surface of the pair of holder side plate portions 34 of the holder member 30, and the first locking hole 23 is provided in the pair of first case side plate portions 212 of the first case member 21. The second locking projections 38 are fitted into and locked to the second locking holes 24, the second locking projections 38 are provided on the outer surfaces of the pair of holder side plate portions 34 of the holder member 30, and the second locking holes 24 are provided on the pair of second case side plate portions 222 of the second case member 22. Since the first case side plate portion 212 covers at least a part of the second case side plate portion 222, the outward deformation of the first case side plate portion 212 is restricted, and the first locking projection 37 can reliably lock the first case member 21. Further, since the second locking projection 38 is provided on the holder-side plate portion 34 at a position closer to the second end 342 than the end of the first case-side plate portion 212, the second case member 22 can be locked at a position where the second case-side plate portion 222 is less likely to be deformed. When the second housing member 22 is slid toward the first housing member 21 and covers the first housing member 21, the inclined surface 382 of the second locking projection 38 opens the second housing side plate portion 222 first, so that the end surface of the second housing side plate portion 222 can be covered without colliding with the end surface of the first housing side plate portion 212.

In the actuator 10, the damper 13 is disposed so as to contact both the movable body 12 and the first and second case members 21, 22 at a position where the movable body 12 faces the first and second case members 21, 22. Therefore, since the damper 13 is not in the same plane as the movable body 12, the permanent magnet 41 in the movable body 12 can be increased in size.

In the actuator 10, the damper 13 (see fig. 2) is provided between the yoke 42, which is the movable body 12, and the housing 20, which is the support body 11, but the damper 13 may be provided between the yoke 42, which is the movable body 12, and the plate 47, which is the support body 11, as shown in fig. 11. Even if the actuator 10 is provided as described above, the actuator 10 can be further thinned while obtaining the same operation and effect as those of the actuator 10. In the actuator 10, the coil 31 is provided on the support 11, the permanent magnet 41 (the first permanent magnet 411 and the second permanent magnet 412) is provided on the movable body 12, and the coil 31 is held by the holder member 30 of the support 11, but the coil 31 may be provided on the movable body 12, the permanent magnet 41 may be provided on the support 11, and the permanent magnet 41 may be held by the holder member 30.
