Can be. In this case, the release member 10 does not move in the radial direction from the position shown in FIG. 5, and the connecting member 9 is held in a state of connecting the key cylinder 6 and the rotor 8. Therefore, the rotational force of the key cylinder 6 is directly transmitted to the rotor 8, and the rotor 8 can be rotated. Rotor 8
The cam surface 8a is moved from the locked position in FIG. 7 to the unlocked position in FIG. 18, so that the slider 13 is also moved from the locked position in FIG. 7 to the unlocked position in FIG. Therefore, the latch 12 can be moved from the locking position in FIG. 1 to the separation position in FIG. 2 and the end 23 a of the wire 23 can be pulled out from the slot 24.

The embodiment of the present invention is not limited to the above-described embodiment, but can be modified. For example, as shown in FIG. 19, the key cylinder 6 is not a free-turn type in which the key cylinder 6 rotates freely at the time of unauthorized unlocking, but the tumbler 7 is locked in a groove 26a formed in the hollow portion 26 of the frame 4 to lock the key cylinder 6 when locked.
