４は略水平状態になる。In the non-energized state, the operating rod 35 of the solenoid 30 extends downward, and the magnetic body 36 thereof separates from the magnetic body 46 of the rotary engaging body 40. Then, the rotary engagement body 40 rotates clockwise due to the spring force of the spring 42. At this time, the magnetic material 46 of the front arm 44 approaches the window portion 14 of the front 31, so that the sickle lock member 60 is pushed by the pushing portion 68 of the engagement releasing member 65 urged by the spring 66. , Rotate counterclockwise. As a result, the short rod portion 64 of the sickle lock member 60 separates from the small protrusion 12 of the sickle piece 6. On the other hand, since the rear arm 45 of the rotary engagement body 40 also rotates in the same direction as the sickle lock member 60, the rotation locking member 50 also rotates by a predetermined amount in the counterclockwise direction by the spring force of the spring 51, and the locking thereof. Arm 5
4 is in a substantially horizontal state.

る。In the above case, the key is inserted into the cylinder 4 of the sickle lock 3 and the cylinder 4 is rotated, but in the present invention, the sliding door 1 can be opened as it is. That is, as shown in FIG. 4, when the sliding door 1 is tried to be fully opened in the non-energized state, the radius 1 of the sickle piece 6 is
Since 0 is in sliding contact with the upper edge of the opening 34 of the receiving member 33, the cylinder 4 of the sickle lock and the pinion member 5 rotate following the opening degree of the sliding door 1, and the rack member 20 moves upward. Therefore, in the event of an emergency such as a fire, if the solenoid 30 is in the non-energized state by the control of the remote control device, the sliding door 1 can be immediately opened without the key.

いるため、引戸１を開けることができない。Then, the rotary engaging member 40 rotates counterclockwise against the spring force of the spring 42. At this time, the magnetized body 46 of the front arm 44 is separated from the window portion 14 of the front 31, so that the sickle lock member 60 rotates clockwise. On the other hand, since the rear arm 45 of the rotary engagement body 40 also rotates in the same direction as the sickle lock member 60, the rotary locking member 50 rotates clockwise against the spring force of the spring 51. Then, the rack member 20 is released from the rotation locking member 50 and is lowered by the spring force of the rack spring 25.
As a result, the pinion member 5 and the cylinder 4 rotate clockwise, and the sickle piece 6 of the sickle lock 3 opens the opening 34 of the receiving fitting 33.
To enter. At this time, the cam projection 9 of the cylinder 4 slides over the pushed-out portion 69 of the engagement releasing member 65 and goes over. Further, the short rod portion 64 of the sickle lock member 60 is the small protrusion 1 of the sickle piece 6.
The second stopper surface 11 and the second stopper surface 11 are engaged with each other. Therefore, since the sickle lock 3 is locked by the sickle lock lock member 60, the sliding door 1 cannot be opened.
