A tree decoration is disclosed which comprises a storage device which has a plurality of storage units. Each of the storage units has a pulley independently rotatably mounted on the shaft, a rigid support member fixedly connected to the shaft and extending transversely outward therefrom adjacent an outside first end of the pulley, a grip, and a resilient polymer segment. The grip is connected to one of the support member and the outside first end surface of the pulley adjacent the other one. The resilient polymer segment is connected to the other one of the support member and the outside first end surface of the pulley, and is dimensioned so as to normally engage against the grip when aligned therewith and cause the pulley to rotate when the shaft is rotated, and to disengage from against the grip in response to a torque applied to one of the shaft and the pulley when the other one is held stationary so that one can rotate while the other is held stationary. Conveniently, a plurality of grips are used which are spokes on an outer lower end surface of the pulley, and a plurality of resilient polymer segments are used which protrude into the spaces between the spokes from an adjacent plate fixedly connected to the shaft. A plurality of garlands are also provided in the tree decoration, each being attached to the pulley in a corresponding one of the storage units.
