To provide an electrically-driven actuator the outer diameter dimension of which can be reduced.SOLUTION: At least one part of an electrically-driven motor 21 projected on a virtual plane orthogonal to a rotary shaft line Lh of a worm wheel 25 is superimposed on at least one of a worm 24 projected on the virtual plane and the worm wheel 25 projected on the virtual plane. The electrically-driven motor 21 does not exist on a side opposite to the worm wheel 25 across the worm 24. Accordingly, at least an external dimension in a vertical direction on a page space becomes smaller than that in a structure where the electrically-driven motor is arranged on a side opposite to the worm wheel across the worm.SELECTED DRAWING: Figure 6

    【課題】 外径寸法を小さくすることが可能な電動式アクチュエータの一例を開示する。【解決手段】 ウォームホィール25の回転軸線Lhと直交する仮想平面に投影された電動モータ21の少なくとも一部は、当該仮想平面に投影されたウォーム24及び当該仮想平面に投影されたウォームホィール25の少なくとも一方と重なっている。ウォーム24を挟んでウォームホィール25と反対側に電動モータ21が存在しない。したがって、ウォームを挟んでウォームホィールと反対側に電動モータが配置された構成に比べて、少なくとも、紙面上下方向の外形寸法が小さくなる。【選択図】 図6
