The second transmission piece 65 rotates following the movement of the magnetized body 46 of the front arm 44 while being pushed out by the pushing portion 68 of the first transmission piece 61, whereby the short rod portion 64 of the second transmission piece 65 is rotated.
The engagement state between the small protrusion 12 of the sickle piece 6 is released. On the other hand, the rear locking arm 45 of the rotary engagement body 40 also rotates in the same direction as the front arm 44, so that the locking portion 47 of the rear locking arm 45 disengages from the engagement protrusion 22 of the rack member 20. Then, the rack member 20 becomes the rotary engagement member 4
Since it is released from 0, it rises due to the spring force of the rack spring 25. Therefore, as the rack member 20 is returned to the initial position by the spring force of the rack spring 25, the engagement of the sickle piece 6 is automatically canceled.

A lock releasing mechanism for the rotary engaging body that releases the lock of the rotating engaging body 40 is operated. Then, when the cylinder 4 is rotated by the key operation, the first transmission piece 61 is pushed by the cam projection 9 to rotate clockwise as shown in FIG. Then, the second transmission piece 65 is pushed out by the first transmission piece 61, and the long rod 63 pushes the magnetized body 46 of the rotary engagement body 40 toward the front 31 side of the lock case 2. As a result, the rotary engagement body 40 rotates clockwise, so that the rack member 20 is released from the rear locking arm 45 of the rotary engagement body 40. Therefore, the sliding door 1 is opened while maintaining the state where the sickle piece 6 is unhooked.

に一旦摺接して他側へ移行する。Then, a key (not shown) is inserted into the cylinder 4 and the cylinder 4 is rotated clockwise. Then, as shown in FIG. 5, the rack member 20 becomes the rack spring 2.
It descends against the spring force of 5. When the rack member 20 descends, the inner tapered surface of the engagement protrusion 22 of the rack member 20 comes into sliding contact with the engagement portion 47 of the rear engagement arm 45, and the engagement protrusion 22 of the rack member 20 engages rearward. Arm 4
Riding on the locking portion 47 of No. 5. As a result, the sickle piece 6 of the sickle lock 3 enters the opening 34 of the receiving fitting 33 and engages with the receiving fitting 33. When the sickle piece 6 engages with the receiving fitting 33, the cam projection 9 of the cylinder 4 pushes the pushed portion 69 of the first transmission piece 61.
