Next, when the door is closed, the door is closed with the operating portion of the operating lever being in a state where the door is opened, and when the movable pillar comes into contact with the fixed pillar, the hook portion at the tip of the hook is removed. , Get over the fixed pin of the fixed column. At the same time, one end of the lock member projecting from the side end surface of the moving column is pushed into the moving column, and the upward protrusion of the locking member lifts the stopper pin at the tip of the engaging piece of the engaging member, By the action of the spring, the operation lever moves to the fixed pillar side,
When the stopper pin climbs over the upward protrusion and the engaging piece falls down due to the action of the second spring, the engaging pin fits into the first concave portion of the engaging piece and the hook is drawn into the moving column. Since the hook moves, the hook is fixed by pulling in the horizontal direction by hooking the fixing pin of the fixing column. This state is the locked state.

When the lock is released, the disengagement piece of the engagement member is moved in the direction in which the engagement piece is disengaged from the engagement pin in the concave portion of the moving column, and the stopper pin is provided with an upward projection of the lock member. And return it to its original position by returning the lock member to its original position by the third spring, so that the operating lever is released and the operating portion of the operating lever is pulled fully in the direction opposite to the fixed column. , The hook protrudes toward the fixed column, and the tip of the hook largely points up, and the fixing pin comes off. When the door is opened in this state, the hook separates from the fixed column. At that time, when the operating portion of the operating lever is released from the hand, the engaging pin of the operating lever fits into the second recess of the engaging piece of the engaging member and is held in the open state.
