A cam slider is movable forward and rearward within the housing; and a spring attaches at one end to the rear of the housing and at the other end to the cam slider. Engaging jaws mounted on the slider can be locked in the engaging holes, and pin guiding slopes, pin engaging slopes and a pin hole of the engaging jaws are configured to receive an actuating pin fixed at a rear position of a movable rail to lock the opening preventing device at the time of drawing-out of a drawer and to unlock the opening preventing device at the time of drawing-in of a drawer.
