Engages with the engaging portion 18b of the unlocking rod 18 for the glass frame and slides it downward. By the downward movement of the unlocking rod 18 for the glass frame, the operating portion 18a pushes down the unlocking lever of the glass frame locking device (not shown), and the glass frame is opened.
[0029]
As described above, in the locked state, the connecting rod 6 connecting the hook members 4 and 5 is locked by the lock member 10, and the hook members 4 and 5 are locked by the locking of the connecting rod 6. Even if it is hooked on the members 4 and 5 and the connecting rod 6, it cannot be moved to the unlocking side. In addition to turning the cam plate 8 by turning the lock shaft of the cylinder lock 7, that is, the cylinder lock 7 removes the key. In this state, the lock shaft is locked and the cam plate 8 cannot rotate. Therefore, unless the unlocking operation is performed using the cylinder lock 7 and an appropriate key, the hook members 4 and 5 are tilted or the connecting rod 6 is slid. It is impossible to move, and unauthorized release by wire or the like can be reliably prevented. When the lock is unlocked, the hook members 4, 5 and the connecting rod 6 are held in the unlocked position by the unlock holding member 15, so that the front frame is opened and the key is removed from the cylinder lock. However, the unlocked state is maintained, and when the front frame is closed, the unlocking holding member 15 hits the abutment portion 24 on the body frame side, unlocking and holding is released, and the hook members 4 and 5 can be locked. When the front frame is closed, the hook members 4 and 5 are automatically locked by the receiving fittings 22 and 23 and can be locked.
