The annular inner resin member 4 has a plurality of axially downgauged portions 6 arranged at intervals in a circumferential direction. The annular outer resin member 5 has filling portions 8 respectively filling the axially downgauged portions 6 and an axial surface covering portion 9 that is located radially inward RI of a tooth side 10C of the teeth 10 and covers the filling portions 8.According to the power transmission resin gear 1, deformation of a molded product due to forcible removal can be reduced without preparing a special tooth shape.
