Abstract
To suppress generation of noise during cranking, a pinion gear is fixed to a drive shaft of a starter starting an internal combustion engine. The pinion gear rotates a ring gear provided to the internal combustion engine by meshing therewith. The pinion gear includes gear teeth and an annular hollow portion located radially inside of the gear teeth. The annular hollow portion accommodates a vibration absorber to absorb vibration generated in the gear tooth.
