The two-wheeled vehicle lock 30 according to the second embodiment has substantially the same structure as that of the first embodiment, but is not provided with the locking prevention plate 19. Then, instead, the locking prevention screw 32 is fixed to the left end portion 33 of the case 34 by being inserted almost vertically from the upper surface 36 to the bottom surface 38 of the case 34. According to the second embodiment, the lock prevention screw 32 is inserted into the case 34 to prevent the cannula 35 from protruding from the left side surface 40 of the case 34. Can be obtained. That is, the lock prevention screw 32 cannot be removed by only the hand, so that the lock 42 cannot be locked, and the key 42 cannot be removed unless it is locked by the latch mechanism, so that the key 42 is prevented from being stolen or lost. Therefore, mischief such as locking and stealing the key 42 is prevented. When it is no longer necessary to prevent locking, such as after sale, by removing the locking prevention screw 32 with a tool not shown, it becomes possible to lock (and unlock) as usual as described above. .

In the second embodiment, the lock prevention screw 32 is provided on the left end portion 33 of the case 34. However, the same applies if the movement of the hood 35 is prevented at any portion that does not affect the cam mechanism. It is possible to obtain various effects. Further, in the second embodiment described above, the locking / locking prevention screw 32 is provided, but it is also possible to prevent the locking by adhering and fixing the rod inside the case 34 so as to prevent the locking. When it is no longer necessary to prevent locking, the case 34 can be disassembled with a tool and removed by cutting the rod. [Third Embodiment] FIGS. 4 and 5 show a motorcycle lock 50 according to a third embodiment.
