To achieve a structure capable of restraining backlash while preventing increase in a size of a housing.SOLUTION: A pressed part 27 is placed in a distal end side of a worm shaft 17 compared to a worm tooth part 26 and at a position shifted in an axial direction from a second support shaft part 25 of an outer peripheral surface of the worm shaft 17. An energizing member body 44 is pressed to the axial direction by a pressing member 45 constituting an energizing member 23, and thereby, a plate spring 46 fixed to the energizing member body 44 is pressed onto the pressed part 27, and the other side in the axial direction of the worm shaft 17 is energized in a direction to come close to a worm wheel.SELECTED DRAWING: Figure 1

    【課題】ハウジングの大型化を防止しつつ、バックラッシュを抑えられる構造を実現する。【解決手段】ウォーム軸17の外周面のうち、ウォーム歯部26よりもウォーム軸17の先端側で、かつ、第二支持軸部25から軸方向に外れた部分に被押圧部27が設けられている。付勢部材23を構成する押圧部材45により、付勢部材本体44を軸方向に押圧することで、付勢部材本体44に固定された板ばね46を被押圧部27に押し付け、ウォーム軸17の軸方向他方側部をウォームホイールに近づく方向に付勢する。【選択図】図1
