A catcher member is provided to be movable between a standby position and a retracted position, and at the standby position, while being urged by an urging device, the catcher member is positioned in the standby position by a holding device. When a movable body is moved forward a predetermined movement position, a striker member is caught and engaged with the catcher member positioned in the standby position, and subsequently, holding by the holding device is released, and the catcher member is moved or relatively moved up to the retracted position by being urged by the urging device, so that the urging force is applied to the movable body up to position where the movement ends. An operation device is provided so as to be able to operate to move the catcher member which was moved to the retracted position without catching the striker member, toward the standby position.
