ABSTRACT:
A gear generally made of plastics for use in such precision devices as timepieces and the like and having improved gear teeth with reduced contacting noises is provided. Each tooth includes means for yielding an elastic deformation of the tooth so that, upon applications of fluctuated load thereto, the fluctuation of load will be cancelled by the elastic deformation of the tooth, whereby a remarkably quiet contacting movement with opposing gear can be achieved.
