<Handle lock module>
A steering wheel lock module 40 for locking the steering wheel 2 (see FIG. 1) is provided in the front upper portion of the vehicle. The handle lock module 40 is attached to the front part of the top bridge 30 at the center in the vehicle width direction. As viewed from the side in FIG. 4, the handle lock module 40 is inclined with respect to the vertical direction so that the upper end is arranged rearward and the lower end is arranged forward.

The steering wheel lock module 40 locks the rotation of the steering shaft 29 (see FIG. 2) (locks the steering wheel 2) when the ignition switch 41 is rotated. The steering wheel lock module 40 comprises an ignition switch 41 , a lock pin 42 , a restricting device 43 and a housing 44 . For example, the handle lock module 40 is electrically operated by a solenoid.

A steering wheel lock module 40 is included in the smart key system (not shown). A smart key system includes an ECU (Electronic Control Unit) mounted on a vehicle body, a transceiver (antenna) connected to the ECU, and a smart key (radio) carried by a driver. The smart key performs two-way communication with the ECU via a transmitter/receiver to authenticate the ID of the smart key. Once the ID of the smart key is authenticated, the engine can be started and each part of the vehicle can be unlocked.

For example, the ON operation of the ignition switch 41 is enabled or validated by ID authentication of the smart key (unlocked state). On the other hand, when the smart key is separated from the transmitter/receiver (ECU) and the communication between the smart key and the ECU is lost, the smart key becomes disabled or invalid (locked state). For example, equipment that can be unlocked and locked by ID authentication of a smart key includes a steering wheel lock, opening and closing of seats, opening and closing of an article storage section and a fuel filler port, and the like. For example, the smart key system performs at least one of visual notification such as flashing hazard lamps and auditory notification such as emitting an electronic sound when locking and unlocking various equipment (Answer back).

7, the ignition switch 41 has a rotation axis RL along the inclination of the handle lock module 40. As shown in FIG. Hereinafter, the direction along the rotation axis RL is referred to as the "axial direction", the direction perpendicular to the axial direction is referred to as the "radial direction", and the direction around the rotation axis RL is referred to as the "circumferential direction". The ignition switch 41 has an axial length. The ignition switch 41 has a knob 41a projecting upward in the axial direction. The knob 41a is exposed upward along the axial direction so that it can be pinched by the passenger.

The ignition switch 41 is rotatable between an off position for stopping the engine, an on position for driving the engine, and a lock position for locking the steering wheel. For example, when the ignition switch 41 is rotated from the OFF position to the ON position, the engine can be started. On the other hand, when the ignition switch 41 is rotated from the ON position to the OFF position, the engine stops.

The locked position is the full steering position of the steering wheel. The full steering position is a position where the steering wheel is substantially turned to either the left or the right. The lock position of the embodiment is the full steering position to the left side (side stand side) of the steering wheel (see FIG. 6). Note that the lock position may be the full steering position to the right.

As shown in FIG. 7, the lock pin 42 protrudes to lock the steering wheel when the ignition switch 41 is rotated to the lock position. The lock pin 42 appears and disappears with respect to the head pipe 21 by rotating the ignition switch 41 . For example, when the steering wheel is rotated leftward by a predetermined angle and the ignition switch 41 is rotated from the off position to the lock position, the lock pin 42 protrudes and engages with the engagement recess 21a of the head pipe 21 (two points shown in FIG. 7). dashed lock pin 42). This restricts the rotation of the front wheel steering system including the steering wheel and top bridge 30 with respect to the head pipe 21 .

The regulation device 43 regulates the rotation operation of the ignition switch 41 . The regulation device 43 releases the regulation of the rotation operation of the ignition switch 41 when the smart key ID is authenticated. For example, the regulating device 43 includes a solenoid having an actuator that can be displaced by energization. For example, the ignition switch 41 is restricted from rotating by engaging a solenoid actuator with the ignition switch 41 . When the ID of the smart key is authenticated, the actuator of the solenoid is energized and the lock is released, so that the ignition switch 41 can be rotated.

<Second embodiment>
In the first embodiment, an example in which the cap 50 does not have a light emitting portion has been described, but the present invention is not limited to this. As shown in FIG. 8, the second embodiment differs from the above-described first embodiment in the aspect of the cap 250 . In addition, in the following description, the same code|symbol is attached|subjected about the structure similar to 1st embodiment mentioned above, and description is abbreviate|omitted.

The cap 250 of the second embodiment comprises a light emitter 255 . The handle lock module 40 comprises an anti-theft unit 254 having a board 256 that unlocks the handle lock module 40 . One of wires 261 and 262 branched from a wire bundle 260 extending from a battery (power source) on the vehicle body side (hereinafter also referred to as “first wire 261”) is connected to light emitting portion 255 . The substrate 256 is connected to the other of the wirings 261 and 262 branched from the wiring bundle 260 (hereinafter also referred to as “second wiring 262”). The light emitting part 255 and the substrate 256 are electrically connected to the battery through wirings 261 and 262, respectively.

As shown in FIG. 10, the cap 250 and the anti-theft unit 254 overlap each other in top view along the axial direction. The light emitting part 255 and the substrate 256 overlap each other when viewed from above along the axial direction. The light-emitting portion 255 and the substrate 256 overlap the housing 44 of the handle lock module 40 when viewed from above in the axial direction. Note that the handle lock module 40 is not provided with a light-emitting portion or the like.

For example, the board 256 includes an electronic circuit board such as a PCB (Printed Circuit Board). For example, the board 256 provides two-way communication with the smart key to provide identity verification of the smart key. Once the ID of the smart key is authenticated, the engine can be started and each part of the vehicle can be unlocked.

As shown in FIG. 9, the cap 250 has an extension 253 extending axially downward from the front portion of the annular portion 51 . The annular portion 51, the extending portion 253, and the pair of left and right bulging portions 52 are integrally formed of the same member. As shown in FIG. 10, the extending portion 253 overlaps the housing 44 of the handle lock module 40 when viewed from above in the axial direction. The extending portion 253 incorporates a light emitting portion 255 (see FIG. 8).

As shown in FIG. 8, the light-emitting portion 255 is built into the cap 250 . The first wiring 261 is connected to the light-emitting portion 255 from below through the inside of the cap 250 (between the extending portion 253 and the housing 44). The anti-theft unit 254 is built into the handle lock module 40 . The second wiring 262 is connected from below to the substrate 256 of the anti-theft unit 254 through a through hole (not shown) provided in the housing 44 .

In this embodiment, an example in which the anti-theft unit 254 is built into the handle lock module 40 has been described, but the present invention is not limited to this. For example, the anti-theft unit 254 may not be built into the handle lock module 40 . For example, the anti-theft unit 254 may be attached to the exterior of the handle lock module 40 . For example, the layout of the anti-theft unit 254 can be changed according to required specifications.

Note that the arrangement of the wirings 261 and 262 is not limited to the example in FIG. For example, as shown in FIG. 11, the first wiring 261 may be embedded in the cap 250 together with the light emitting portion 255. As shown in FIG. The second wiring 262 may be built into the steering wheel lock module 40 together with the anti-theft unit 254 .

For example, the pair of left and right light emitting portions 255A and 255B may not overlap the substrate 256 when viewed from above along the axial direction. The wirings 261A, 261B connected to the pair of left and right light emitting portions 255A, 255B may be pulled out from the cap 250 and distributed to the left and right sides of the housing 44 of the handle lock module 40 . The pair of left and right light emitting portions 255A and 255B may be arranged at positions sandwiching the substrate 256 when viewed from above along the axial direction. In this case, the wirings 261A and 261B connected to the light emitting portions 255A and 255B are easily drawn out from the housing 44 of the handle lock module 40, so that the wirings 261A and 261B can be preferably arranged.

<Effect>
In the second embodiment, the handle lock module 40 comprises an anti-theft unit 254 having a board 256 for unlocking the handle lock module 40, the cap 250 comprises a light emitting part 255, the light emitting part 255 and the board 256 have: The wirings 261 and 262 are connected to each other, and the cap 250 and the anti-theft unit 254 overlap each other when viewed from above, thereby providing the following effects.
Compared to the case where the cap 250 and the anti-theft unit 254 are separated from each other in top view, the light-emitting portion 255 and the substrate 256 are closer to each other, so it is easier to arrange the wirings 261 and 262 efficiently. In addition, if the light-emitting portion 255 is not provided in the handle lock module 40 but is provided in the cap 250, the handle lock module 40 can be made smaller.

<Modification>
In addition, in the above-described embodiment, an example in which the protective portion entirely surrounds the outer periphery of the handle lock module has been described, but the present invention is not limited to this. For example, the protector may partially surround the outer circumference of the handle lock module. For example, as shown in FIG. 13, the protective portion 134 may have a cutout shape that partially covers the outer circumference of the handle lock module 40 (see FIG. 5). The protector 134 may have a notch 135 into which the handle lock module 40 can be inserted. The protective portion 134 may include a pair of tips 137 facing each other with a gap Wn smaller than the maximum width Wmax of the notch 135 .
In other words, the protective portion only needs to satisfy either (A) or (B) below.
(A) The protective portion 34 has a closed shape that covers the outer circumference of the handle lock module 40 (see FIG. 3).
(B) The protective portion 134 has a cutout shape that partially covers the outer circumference of the handle lock module 40, and is spaced at a distance Wn smaller than the maximum width Wmax of the cutout 135 into which the handle lock module 40 can be inserted. It has a pair of tips 137 facing each other (see FIG. 13).
According to this configuration, the protective portion satisfies either (A) or (B) above and covers the outer periphery of the handle lock module, so that the pair of tips are opposed to each other with an interval equal to or larger than the maximum width of the notch.
