SOLUTION: A sprocket 3, having circumferentially formed projections engaging with circular holes of chains 2a, 2b, is set on the pedestal of the movable partition 12 to be rotated by a motor 7 rotating in both directions. The first chain 2a is connected to the rear end side of the box 10 on one end while connected to the front end side on the other end. The second chain 2b is connected to the front end side of the box 10 on one end while connected to the rear end side on the other end.
