The lock 1 of the embodiment will be described. The housing 3 is provided on one leg 2a of the U-shaped plate 2, and the engaging boss 4 is provided on the other leg 2b.
[0008]
The housing 3 is supported so as to be rotatable about an axis along a vehicle body shaft 5 standing upright from the tip of the leg 2a. The cannula 6 protrudes into the bearing holes 3a and 3b provided in the housing 3 and the upper and lower ends protrude. In the housing 3, the rack portion 7 provided on one outer periphery of the cannula 6 and the pinion 8 pivotally supported by the housing 3 are engaged with each other in the housing 3, and the pinion 8 is always connected to the vehicle body shaft 5. When the whole is pushed into the housing 3 by pushing the upper end of the cannula 6, the pinion 8 rotating by the rack portion 7 is rotated around the fixed gear 9 by the rotational force. When rotated 90 degrees, the cannula 6 becomes horizontal. Here, a rack notch 7a is provided on one outer periphery of the cannuki 6 following the rack part 7 so that the cannula 6 can be pushed in horizontally without rotating the pinion 8, and the lower end of the cannuki 6 is faced. It engages with the engaging boss 4. As a result of this movement, the lock groove 12 provided on the outer peripheral surface of the cannula 6 is engaged with the lock piece 11 that is always urged in conjunction with the cylinder lock 10 provided in the housing 3 to lock the cannula 6. In this state, the kanuki 6 locks wheels (not shown).
[0009]
In order to release the lock state of the cannula 6, for example, the key 13 inserted into the cylinder lock 10 is turned to move the lock piece 11 from the lock groove 12 to the open position, and when the cannula 6 is released, the slide return spring 14 is released. The kanuki 6 is slid by the action of the above, and the lower end of the kanuki 6 is removed from the engaging boss portion 4, and the rack portion 7 on one side outer periphery of the kanuki 6 is reengaged with the pinion 8 by the slide. On the other hand, the housing 3 is biased so as to return to a fixed position by the rotation return spring 15, and thus acts in an overlapping manner with the slide return spring 14, and the housing 3 rotates around the axis of the vehicle body shaft 5. Then, it returns to the original open position and returns the cannula 6 to the vertical position.
[0010]

The operation portion 18b at the upper end is slightly protruded from the end face opening 21 at the upper end portion of the kanuki 6. Therefore, unless the engaging portion 18a is engaged with the outer surface of the housing 3 and this engagement is released, the cannula 6 cannot be pushed into the housing 3.
[0011]
The unlocked state holding mechanism 16 is operated by a finger that pushes the cannula 6 and moves the operating portion 18b of the safety lever 18 prior to the pushing operation so that the engaging portion 18a and the outer surface of the housing 3 are engaged. It can be pushed in by removing it.
[0012]
Next, the lock 22 of the second embodiment of the lock for a two-wheeled vehicle such as a bicycle, a motor-driven two-wheeled vehicle, or a motorcycle according to the present invention will be described with reference to FIGS. 6 and 7, as in the first embodiment. A housing 24 is provided on one leg 23a of the U-shaped plate 23, and an engagement boss 25 is provided on the other leg 23b.
[0013]
The housing 24 is supported so as to be rotatable about an axis along a vehicle body shaft 26 standing upright on one surface of one leg portion 23a, and a fixed internal gear portion 27 corresponding to the housing 24 around the axis of the vehicle body shaft 26 is supported. Is fixed to one surface of one leg portion 23a, and the fixed inscribed gear portion 27 and the pinion 28 pivotally supported by the housing 24 are always meshed with each other.
[0014]
A bearing hole 29 is provided in the housing 24 to slidably support the cannula 30, and a rack part 31 provided on one side of the cannula 30 is engaged with the pinion 28.
[0015]
When the upper end of the cannula 30 is pushed and slid downward, the pinion 28 is rotated from the position shown in FIG. 6 to move the meshing position along the fixed inscribed gear portion 27, and the housing 24 is moved to the vehicle body shaft 26. Rotating around, the cannula 30 is moved horizontally and its lower end is automatically made to correspond to the engagement boss part 25.
[0016]
Therefore, when the cannuki 30 is further pushed in horizontally, the rack notch 31a of the cannuki 30 corresponds to the pinion 28. Therefore, the cannuki 30 can be slid without rotating the pinion 28. A lock piece (not shown) associated with the cylinder lock 33 provided in the housing 24 falls into the lock groove 32 recessed on one side near the upper end, and the cannula 30 is locked at that position.
[0017]
