Abstract

A worm wheel (24) includes: a sleeve (50); and a toothed portion (60) provided by injection molding so as to cover a part of the sleeve (50), the toothed portion including a first thick portion (63) provided on a first side face (54a), which is a surface of the sleeve (50) on a side closer to an injection-mold gate in an axial direction, and a second thick portion (64) provided on a second side face (54b), which is a surface on an opposite side to the first side face (54a). A central part (54cc), in the axial direction, of the outer peripheral surface (54c) of the sleeve (50) projects in the radial direction relative to both ends (54ca, 54cb) in the axial direction. The first thick portion (63) of the toothed portion (60) has a smaller thickness in the axial direction than the second thick portion (64).
