The cam follower is pressed to the first and second movable cams and the fixed cam by a load of an article and a spring force of the spring. A pressing force to the cam follower, of the fixed cam includes a vertical component according to a height position of the supporting portion, and the vertical component compensates or eliminates the force of the spring to press up the load. Each of the cams is designed so that the load, the spring force and the pressing force to the cam follower from each of the cams, acting around the cam follower, are balanced.
