To provide an electric motor with a worm speed reducer and an electric power steering system capable of alleviating an interference sound caused by a worm gear and a worm shaft.SOLUTION: An electric motor with a worm speed reducer and an electric power steering system include: a worm gear; a first housing that rotatably supports the worm gear; a worm shaft; a second housing that rotatably supports the worm shaft; an elastic member interposed between the first housing and the second housing; and a pin that couples a second region of the second housing swingably to a first region of the first housing. When seen from a third direction intersecting both a first direction and a second direction, a meshing part of the worm gear and worm shaft are aligned with the pin in the first direction.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ー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】ウォー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、ウォームホイールと、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、ウォームシャフトと、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配置される弾性部材と、第1ハウジングにおける第1部位に対して第2ハウジングにおける第2部位を揺動可能に連結するピンと、を備える。第1方向および第2方向の双方に交差する第3方向から見た場合に、ウォームホイールおよびウォームシャフトの噛合部分と、ピンとは、第1方向に並ぶ。【選択図】図4
