る。In the lock mechanism B, the front side protrusion 20
2 is formed on the arm member 201a and the lock member 20
The main body 200a of No. 0 is rotatably supported so as to vertically move the end portion on the side of the engaging surface 201d about the shaft 200c. When the engagement is released, the engagement means M ′ causes the front side protrusion 2 where the engagement surface 201d of the arm piece 201a and the inclined surface 201c come into contact with each other.
It is possible to slightly push down the arm piece 201a against the urging force of the spring 200d when getting over the top portion 201e of 01. Therefore, the engagement state of the engagement means M ′ of the moving body and the front side protrusion 201 is smoothly released.

01a is rotatably pivoted so as to move up and down around the shaft 200c at the end on the engagement surface 201d side. Therefore, the engagement means of the moving body that has been moved toward the lock mechanism B again. M'is brought into contact with the inclined surface 201c of the front side projection 201 to push the arm piece 201a downward against the bias of the spring 200d, whereby the engaging means M'overrides the top 201e. Then, after this, the arm piece 201
By returning a to the upper side, the engaging means M ′ can be properly engaged with the engaging surface 201d again, and the malfunction state can be returned to the normal state.
