Claim 6:
7. The ceiling suspended shelf according to claim 3, wherein
the switching mechanism includes:
a coupling belt;
a first reel that is rotatable integrally with the first shaft, the first reel including the coupling belt wound thereon; and
a second reel that is rotatable integrally with the second shaft, the second reel including the coupling belt wound thereon in the same winding direction as on the first reel;

as the first reel is rotated by an external driving force and the coupling belt is wound onto the first reel, the second reel is rotated in the direction reverse to a rotation direction of the first reel; and
as the second reel is rotated by an external driving force and the coupling belt is wound onto the second reel, the first reel is rotated in the direction reverse to a rotation direction of the second reel.
