PROBLEM TO BE SOLVED: To provide a worm wheel which includes resin made gear teeth and enables improvement of mechanical strength even when the worm wheel does not necessarily include a fibrous reinforcement material.SOLUTION: A worm wheel engages with a worm gear to transmit power. The worm wheel has resin gear teeth which engage with the worm gear. The gear teeth includes: an engagement part which engages with the worm gear; and an annular part which continues in a circumferential direction on at least one end in a tooth width direction.SELECTED DRAWING: Figure 3
【課題】樹脂製のギヤ歯を備えたウオームホイールにおいて、繊維状補強材を必ずしも含有しない場合でも、機械的強度を向上させることができるウオームホイールを提供する。【解決手段】ウオームギヤと噛み合って動力を伝達するためのウオームホイールであって、該ウオームホイールは、前記ウオームギヤと噛み合う樹脂製のギヤ歯を有し、該ギヤ歯は前記ウオームギヤと噛み合う噛合部と、歯幅方向の少なくとも一端において周方向に連続した環状部とを備えている。【選択図】図3
