PROBLEM TO BE SOLVED: To further improve a rotary feeling of a fishing reel transmitted to a handle.SOLUTION: A drive gear 11 of a spinning reel 100 is engaged with a pinion gear 12. The drive gear 11 includes a gear body 11a, a plurality of drive gear teeth 11b and a waveform adjusting unit 16. The gear body 11a is provided in a drive shaft 10. The plurality of drive gear teeth 11b are provided at intervals in a circumferential direction at an outer peripheral side of the gear body 11a, and engaged with the pinion gear 12. A waveform adjusting unit 16 is provided in at least a portion of the plurality of drive gear teeth 11b, and performs adjustment so that a waveform WS of vibration generated in gearing becomes non-uniform. The waveform adjusting unit 16 performs adjustment so that the waveform WS becomes non-uniform by varying at least any of a pressure angle PA, a pitch PE, a torsion angle TA, a tooth profile shape TS and a tooth trace shape TLS between at least one drive gear tooth 11b and remaining drive gear teeth 11b.COPYRIGHT: (C)2015,JPO&INPIT【課題】ハンドルに伝わる釣り用リールの回転フィーリングをさらに向上させる。【解決手段】スピニングリール100の駆動ギア11は、ピニオンギア12に噛み合う。駆動ギア11は、ギア本体11aと複数の駆動ギア歯11bと波形調整部16とを備える。ギア本体11aは駆動軸10に設けられる。複数の駆動ギア歯11bは、ギア本体11aの外周側に周方向に間隔を隔てて設けられ、ピニオンギア12に噛み合う。波形調整部16は、複数の駆動ギア歯11bの少なくとも一部に設けられ、噛み合いにおいて発生する振動の波形WSが不均一になるように調整する。波形調整部16は、少なくとも1つの駆動ギア歯11bと残りの駆動ギア歯11bとの間で、圧力角PA、ピッチPE、ねじれ角TA、歯形形状TS、及び歯すじ形状TLSの少なくともいずれかを異ならせることによって、波形WSが不均一になるように調整する。【選択図】図5
