Abstract
A resin gear has a concave portion formed on a gear body at a position radially inward of a boundary region between a toothed portion and a non-toothed portion. During a molding process, a welded portion is formed at the non-toothed portion by merger of flow of the molten resin along a first path and flow of the molten resin along a second path. The first path detours the concave portion and passes through the side of the toothed portion, and the second path detours the concave portion and passes through the side of the non-toothed portion.
