Abstract:
A resin gear has a plurality of teeth on an outer periphery thereof. One surface of each tooth has a tooth plane which meshes with another gear. The tooth thickness is substantially uniform from a tooth tip to a tooth root. A reinforcing rib is provided on the surface of each tooth on the opposite side from the tooth plane.
