Summary:To provide an electric actuator having a configuration in which productivity is improved.SOLUTION: An electric actuator includes: a driving gear 62 connected to a speed reduction mechanism; an output shaft 61 to which the driving gear 62 is fixed; and a slide bearing 65 rotationally supporting the output shaft 61. The output shaft 61 includes: a body part 61a; a shaft flange part 61b projecting outward from the body part 61a in an output radial direction about a center axis J3 of the output shaft 61; and an annular projection part 61k projecting outward from the body part 61a in the output radial direction and positioned apart from the shaft flange part 61b on one side in a predefined direction. The slide bearing 65 rotationally supports a part of the body part 61a that is positioned on one side in a predefined direction from the annular projection part 61k. The shaft flange part 61b supports the driving gear 62 from the other side in the predefined direction. The driving gear 62 includes a press-in hole 62c in which the annular projection part 61k is pressed.SELECTED DRAWING: Figure 8 【課題】生産性を向上できる構造を有する電動アクチュエータを提供する。【解決手段】電動アクチュエータは、減速機構に接続された駆動ギア62と、駆動ギア62が固定された出力シャフト61と、出力シャフト61を回転可能に支持する滑り軸受65と、を備える。出力シャフト61は、本体部61aと、出力シャフト61の中心軸J3を中心とする出力径方向において本体部61aから外側に突出するシャフトフランジ部61bと、本体部61aから出力径方向の外側に突出し、シャフトフランジ部61bから所定方向の一方側に離れた位置に位置する環状突起部61kと、を有する。滑り軸受65は、本体部61aのうち環状突起部61kよりも所定方向の一方側に位置する部分を回転可能に支持している。シャフトフランジ部61bは、駆動ギア62を所定方向の他方側から支持している。駆動ギア62は、環状突起部61kが圧入された圧入孔62cを有する。【選択図】図8
