がある。(Effect of the Invention) As described above, according to the present invention, the operation member for closing the ignition switch is returned from the end position of the operation member to the intermediate position in conjunction with the pressing operation of the operation member from the start position to the end position. A switching means for switching the ignition switch to an inoperative position where the ignition switch cannot be pressed in conjunction with the operation, and switching the operation element to an operation position where the ignition switch can be operated in conjunction with a return operation from the intermediate position to the start position. Since the operating member is switched to the inoperative position where the ignition switch cannot be pressed by the switching means in conjunction with the return operation of the operating member from the end position to the intermediate position by the switching means, the operating member is temporarily moved to the start position. The ignition switch is not operated unless the operation is returned to the normal position, and when the operation member is pushed again from the intermediate position in which the shut-off valve is open, the ignition plug is operated. The ignition switch can be prevented from being operated at the time of the re-pressing operation without using a deformed heart cam for the lock device as in the conventional example, and the problem associated with using the deformed heart for the lock device can be solved. Has the effect.
