Abstract
A drive gear for a spinning reel is meshed with a pinion gear. The drive gear has a gear body, a plurality of drive gear teeth and a waveform regulating part. The gear body is mounted onto a drive shaft. The plurality of drive gear teeth are disposed on an outer peripheral side of the gear body, are circumferentially disposed at intervals and are meshed with the pinion gear. The waveform regulating part is disposed on at least a part of the plural drive gear teeth, and is configured to regulate a waveform of a vibration produced in meshing in an irregular pattern. The waveform regulating part is configured to regulate the waveform in the irregular pattern by having at least one feature of the drive gear teeth be different from the rest of the drive gear teeth, the at least one feature being selected from the group consisting of a pressure angle, a pitch, a torsion angle, a tooth profile shape and a tooth trace shape.
