To provide an electric motor with a worm speed reducer and an electric power steering device that can further reduce interference sound between a worm wheel and a worm shaft.SOLUTION: An electric motor with a worm speed reduce and an electric power steering device include: a first housing that houses a worm wheel and supports the worm wheel such that the worm wheel is rotatable; a second housing that houses a worm shaft engageable with the worm wheel and supports the worm shaft such that the worm shaft is rotatable; and an elastic member that is disposed in a sandwiched state between the first housing and the second housing. The first housing and the second housing are fixed via a fixing member in a state where the elastic member is elastically deformed.SELECTED DRAWING: Figure 4
【課題】ウォームホイールとウォームシャフトとの干渉音をより低減することが可能なウォ-ム減速機付き電動機および電動パワーステアリング装置を提供すること。【解決手段】ウォ-ム減速機付き電動機および電動パワーステアリング装置は、ウォームホイールを収容し、且つ、当該ウォームホイールを回転可能に支持する第1ハウジングと、ウォームホイールに噛み合うウォームシャフトを収容し、且つ、当該ウォームシャフトを回転可能に支持する第2ハウジングと、第1ハウジングと第2ハウジングとの間に挟まれた状態で設けられる弾性部材と、を備える。第1ハウジングと第2ハウジングとは、弾性部材が弾性変形した状態で、固定部材を介して固定される。【選択図】図4
