2. Description of the Related Art In Japanese Patent Laid-Open No. 62-198572, a pair of left and right arm portions extending downward from a seat rail are disposed on opposite side surfaces with a wheel sandwiched therebetween, and the tip ends of these left and right arm portions are arranged. There is shown a lock device for a motorcycle, in which a lock body is connected to and locked by a substantially rod-shaped lock main body that is passed through a spoke from one side surface of the wheel in a vehicle width direction.

[0003]

By the way, since the left and right arm portions in the above-mentioned conventional example are provided as separate bodies and are welded or rotatably attached to the vehicle body side, the space between the left and right arm portions is reduced. When connecting with one lock body, it is necessary to accurately position each of the left and right arm end portions at the same position with the wheel in between.

However, if the arms are separated into left and right bodies as in this example, it becomes difficult to attach the arms that can be accurately positioned to the left and right when they are attached to the vehicle body by welding. Moreover, in particular, when the left and right arm portions are made rotatable, the left and right arm portions must be aligned each time locking is performed, which takes time and labor, which makes quick locking impossible. Then, this invention aims at solving such a problem.

[0005]

Means for Solving the Problems To solve the above problems, a motorcycle locking device according to the invention of the present application is a lock having a pair of left and right arm portions that can be respectively disposed on both axial side surfaces of a wheel. The lock bar is provided with a bar and a substantially rod-shaped lock body that is passed through the spokes in the axle direction from one side surface of the wheel and engages with each tip of the lock bar to lock at least one side. By connecting the left and right arm parts at positions apart from the respective tip parts by a cross part that traverses outward, it is formed as a substantially U-shaped left and right integrated component,
In addition, it is characterized in that the left and right arm portions are rotatably attached to the vehicle body side so that the respective tip portions thereof rotate integrally.

[0006]

Since the lock bar is substantially U-shaped, and the pair of left and right arm portions 41 and 42 and the cross portion 40 are continuous components, when the left and right arm portions are rotated to lock the wheels. The front ends of the arm portions of the lock bar are arranged on the opposite side surfaces with the wheel in between, and are aligned with each other. Therefore, when the lock body is passed between the spokes in the vehicle width direction, the lock bodies can be quickly engaged with the distal end portions of the respective arm portions.
