A rotary knob type ignition switch 26 and a storage bag 27 are disposed on the leg shield 8 disposed below the handle cover 5. The throttle device 40 of the present embodiment is attached to the right side steering handle 3 in the vehicle width direction.

Fig. 3 is a perspective view of the throttle device 40. The throttle device 40 is fixed to a right end portion of a not-shown handlebar constituting the steering handle 3 so as to be fixed to a tube. The housing 42 serving as a grip support body is composed of a rear housing 42a and a front housing 42b, the rear housing 42a and the front housing 42b are formed of synthetic resin or the like, and a handle is inserted into a communication hole 49 formed by fastening the rear housing 42a and the front housing 42b with two bolts 47. A positioning protrusion 48 for positioning the handle is provided on an inner peripheral portion of the communication hole 49.

The handle grip 41 formed of rubber or the like functions as a throttle operation member that is rotatable with respect to the housing 42. The throttle device 40 is an electrical type that converts the rotation angle of the handle grip 41 that is rotationally operated by the right hand of the driver into a sensor signal, and the sensor signal is output from a wire harness 44. The housing portion of the sensor for detecting the rotation angle of the handle grip 41 is covered with a cover 45. The cover 45 is fixed to the rear housing 42a by a fastening member 50 (see fig. 4) screwed into the screw hole 46.

Fig. 4 is a perspective view of throttle device 40 with cover 45 removed. Fig. 5 is a front view of the case 60. Fig. 4 and 5 show the front, rear, top, and bottom directions with reference to the direction of attachment to the vehicle body.

In the present embodiment, a case 60 holding a hall element 81 as a sensor is provided, and the hall element 81 is housed at a predetermined position by housing the case 60 in a housing portion 57 formed in the housing 42. With this configuration, the common case 60 can be used even for different housings, and the mounting structure of the hall element 81 does not need to be specially designed, which can reduce the cost.

The case 60 is fixed to the housing 57 by a fastening member 50, and the fastening member 50 is screwed to a position on the radially outer side of the case 60 when viewed in the axial direction of the handle grip 41. The main body 61 of the case 60 is formed with a through hole 70 through which the fastening member 50 passes. The fastening member 50 is configured to fasten and fix the cover 45 and the case 60 together to the housing portion 57.

The outer wall surface of the case 60 is provided with positioning convex portions 64 and 65 having a front-rear symmetrical shape, a case-side inclined portion 62 located at an upper portion in front, and a bent portion 66 located at a lower portion. The positioning protrusions 64 and 65 correspond to the positioning recesses 55 and 56 (see fig. 6 and 7) formed in the housing 57, and thus the positioning of the case 60 can be reliably and easily performed. Further, the case-side inclined portion 62 corresponds to the housing-side inclined portion 52 (see fig. 6 and 7) formed in the housing portion 57, so that the case 60 can be downsized and erroneous assembly at the time of assembly can be prevented. The bending portion 66 is bent in accordance with the shape of the magnet 100 as the object to be detected by the hall element. This arrangement not only improves the sensor accuracy by disposing the hall element 81 and the magnet 100 close to each other, but also enables the vertical dimension of the case 60 to be reduced.

The hall element 81 is mounted on the lower surface of the small substrate 80. The substrate 80 is accommodated in a recess 63 formed in the main body portion 61. Specifically, the substrate 80 is engaged with the substrate holding grooves 67 and 68 formed on the front and rear inner walls of the recess 63, and is stored at a predetermined position. The bottom surface 69 of the case 60 facing the lower surface of the hall element 81 is thinner than the other wall portions, which contributes to improvement in sensor accuracy. The curved portion 66 is curved in a concave shape toward the magnet 100 and is disposed close to the magnet 100.

Fig. 6 is a front view of the housing 57 with the case 60 removed. Fig. 7 is a front view of the housing portion 57 from the state of fig. 6 with the spacer member 90 removed. The case 60 is made of synthetic resin or the like, and the gasket member 90 (shown in dotted lines) is made of a thin metal plate. The spacer member 90 is a tool for stably supporting the case 60 in the housing 57.

The housing portion 57 is provided with a female screw hole 51, and the fastening member 50 made of a tapping screw or the like is screwed into the female screw hole 51. A housing-side inclined portion 52 corresponding to the case-side inclined portion 62 is formed in front of the female screw hole 51. A rear positioning recess 55 is formed below and behind the female screw hole 51, and a positioning protrusion 65 provided on the case 60 is engaged with the rear positioning recess 55. A front positioning concave portion 56 is formed in front of the positioning concave portion 55, and a positioning convex portion 64 provided in the case 60 is engaged with the front positioning concave portion 56. The front positioning recess 56 is formed by two projections 53 and 54 which abut against the side portions of the gasket member 90.

Fig. 8 is a perspective view of the case 60 in a state where the gasket member 90 is combined. Fig. 9 is a perspective view of the case 60 in a state where the gasket member 90 is combined, and fig. 10 is a perspective view of the gasket member 90. A gasket member 90 made of a thin metal plate is engaged with the back surface side of the case 60, and has a function of protecting the case 60 when the fastening member 50 is fastened.

The gasket member 90 has: a 1 st support portion 92 that supports the back surface side of the through hole 70; a horizontal plane portion 94 extending horizontally from a lower end portion of the 1 st support portion 92; a 2 nd support portion 93 rising from a side portion of the horizontal surface portion 94 and pressing the upper surface of the main body portion 61; and a 3 rd supporting portion 95 which descends from an end of the horizontal surface portion 94 and presses a side surface of the main body portion 61. The 1 st support portion 92 is formed with a through hole 91 through which the fastening member 50 passes.

As described above, the substrate holding grooves 67 and 68 for holding the substrate 80 are formed in the side walls of the recess 63 for accommodating the substrate 80. The substrate holding grooves 67, 68 are formed on the back side of the positioning projections 64, 65 provided on the outer wall surface of the case 60. This makes it possible to reduce the size of the case 60 while maintaining a predetermined thickness.

Fig. 11 is a sectional view of throttle device 40. Fig. 12 is a sectional view taken along line XII-XII of fig. 11. As described above, the housing 42 is fixed to the outer peripheral portion of the handlebar 3 a. An extension 42c that covers the outer periphery of the handlebar 3a is provided on the vehicle width direction right side of the housing 42. The magnet support portion 101 that supports the magnet 100 is rotatably supported by the extension portion 42c and is housed in the case 42. The cylindrical rotating portion 102 is connected to the right side of the magnet support portion 101 in the vehicle width direction. The rotating portion 102 and the extending portion 42c are slidably engaged with each other.

A handle weight 104 and a handle end member 105 are fixed to the outer end of the handlebar 3a by bolts 106. A pipe member 103 fitted into the handlebar grip 41 at a position on the vehicle width direction right side of the handlebar grip 41 is fixed to the rotating portion 102 by its left end portion.

The bottom wall of the case 60 facing the hall element 81 mounted on the board 80 is made thin, and the distance between the hall element 81 and the magnet 100 is reduced, thereby improving the sensor sensitivity.

As described above, according to the throttle device of the present invention, since the housing 57 for housing the case 60 is provided in the case 42, the case 60 for holding the hall element 81 can be separated from the case 42, and the case 60 can be provided with versatility, whereby the number of designing steps and cost can be reduced.

Further, since the positioning convex portions 64 and 65 are formed on the outer wall surface of the case 60 and the positioning concave portions 55 and 56 into which the positioning convex portions 64 and 65 are engaged are formed on the inner wall surface of the housing 57, the case 60 can be reliably and easily positioned with respect to the housing 57.

Further, since the case 60 holds the substrate 80 on which the sensor 81 is mounted and the substrate holding grooves 67 and 68 for holding the substrate 80 are formed on the back side of the positioning convex portions 64 and 65, the substrate holding grooves 67 and 68 are formed in correspondence with the positions of the positioning convex portions 64 and 65, and thus the case 60 can be downsized while maintaining a predetermined thickness.

Further, since the curved portion 66 that is curved in a concave shape toward the magnet 100 and is disposed close to the magnet 100 is formed on the outer wall surface of the case 60, the hall element 81 and the magnet 100 can be disposed close to each other, the sensor sensitivity can be improved, and the throttle device 40 can be downsized.

Further, since the case-side inclined portion 62 is formed on the outer wall surface of the case 60 and the housing-side inclined portion 52 corresponding to the case-side inclined portion 62 is formed on the inner wall surface of the housing 57, it is possible to prevent erroneous assembly when the case 60 is assembled to the housing 57 and to reduce the size of the housing 42.

The form of the electric motorcycle, the shape and structure of the throttle device, the shape and structure of the housing and the case, the shape of the housing, the forms of the substrate and the hall element, and the like are not limited to the above embodiments, and various modifications are possible. The throttle device of the present invention can be applied to a saddle-ride type tricycle, a four-wheel vehicle, or the like to which a steering handle formed of a handle bar is applied.
