[II] Effects of the Embodiment According to the above-described embodiment, the on-start switch 66A and the unlock switch 66B of the transmitter 66 are operated to transmit the radio wave including the encryption code.
Actuates an ignition coil 87 and an igniter 88, which are engine ignition devices, drives a starter motor 68 to start the engine 4, and further, a receiver 67 operates an actuator 37 of the steering lock mechanism 34 to release the steering lock. Thus, the engine start and the steering lock release can be easily performed by remote control.

Further, since the engine 4 is started and the steering lock is released by the action of the radio wave transmitted from the transmitter 66 as described above, the motorcycle 1 is stolen due to damage of the ignition key device by a flathead screwdriver. Also, it is possible to prevent the motorcycle 1 from being stolen due to unauthorized unlocking by picking. Further, the theft of the motorcycle by anyone other than the owner of the transmitter 66 can be prevented.

Further, since the engine is started by remote control from the transmitter 66 and the steering lock is released, the engine 4 can be warmed up while staying in the room, and the engine 4 can be operated without looking for the keyhole even in the dark. Can be started.

Further, even if the start-on switch 66A of the transmitter 66 is operated, if the transmission is in the neutral position and the stand comes out and the contact of the safety relay 89 in FIG. Since it was configured not to drive, the engine 4
Can be safely started.

Further, the microcomputer 71 of the receiver 67 shown in FIG. 11 operates the starter relay 74 on and off in a fixed pattern shown in FIG. Since the battery is driven / stopped in the above-described pattern, the discharge amount of the battery 76 can be reduced, and the battery can be prevented from running out.

The vehicle body side start switch 27 shown in FIG.
7 is connected in parallel with the contact of the starter relay 74, so that the starter motor 68 can be driven by the rider manually turning on the vehicle body side start switch 27, and the engine 4 is manually started. Can be done.

Further, as shown in FIG. 11, the actuator 37 of the steering lock mechanism 34 operates only when the signal processing circuit 54 receives power supply from the power supply lines 90A and 90B and simultaneously inputs an unlock signal from the signal line 91. Since the steering lock is released by turning on the solenoid 52, the steering lock cannot be released only by directly connecting the power supply to the actuator 37, and the theft of the motorcycle 1 can be prevented.

Since the power supply circuit 72 of the receiver 67 shown in FIG. 11 has a built-in auto cut-off circuit, the power supply of the battery 76 can be saved when not in use for a long period of time, and the running out of the battery can be prevented.

As shown in FIG. 3, since the lock bar 36 of the actuator 37 moves upward from below the vehicle and engages with the engaging hole 40 of the engaging member 35, the steering lock is performed. When the actuator 37 fails, the lock bar 36 can be prevented from engaging with the engagement hole 40 by its own weight and locking the steering.
Safety can be ensured.

Further, since the transmission of the force from the lock hand lever 39 to the lock bar 36 is only in the direction to lock the steering, even if the lock hand lever 39 is broken, the lock bar 36 is Engagement hole 4
0, and the theft of the motorcycle 1 can be prevented.

Since the lock hand lever 39 is provided above the upper bracket 20, the operability of the steering lock can be improved.

Moreover, this lock hand lever 39
Since the lock is normally locked by the safety lever 61, even if the rider accidentally touches the lock hand lever 39, the lock hand lever 39 does not operate and the steering lock during traveling or the like can be prevented.

Further, as shown in FIG. 3, since the mounting portion 43 of the actuator case 41 is formed in a U-shaped cross section, the lock bar 36 is engaged with the engaging hole 40 of the engaging member 35, and the steering is performed. Even if the bolt 44 is removed and the actuator case 41 is to be removed from the motorcycle while locked, the lock bar 36 and the engagement hole 40 cannot be disengaged due to the mounting horizontal portion 43A.
