Abstract

A small decoration capable of exhibiting play characteristics sufficient to provide a key ring with unexpectedness. The small decoration includes a container provided with a key ring mounting section. In the container is arranged a spring drive unit including a drive mechanism which includes a plurality of gears driven by a spiral spring. The drive mechanism also includes two gear shafts arranged so as to vertically project from the spring drive unit. One of the gear shafts is mounted with a decorative element such as a doll and the other gear shaft is mounted with a spring winding-up element. The spring winding-up element is adapted to wind up the spiral spring in association with closing of a lid member pivotally connected to the container and be returned to the original state while unwinding the spiral spring to actuate the decorative element when the lid member is open.
