PROBLEM TO BE SOLVED: To provide an electric actuator in which operation of connecting a conductive member to an electric motor can be easily performed, and sealing between the conductive member and a case is not necessary.SOLUTION: The electric actuator comprises a drive unit having an electric motor 7, and a motion conversion mechanism unit that converts rotary motion of the drive unit to linear motion. The motion conversion mechanism unit comprises a nut that rotates in response to the rotary motion of the drive unit, and a screw shaft that is disposed on the inner circumference of the nut and that linearly moves in association with the rotation of the nut. In the electric actuator, a case 10 and a conductive member 19 formed integrally with the case 10 are provided. The conductive member 19 has an insertion portion 194. A motor terminal 7c of the electric motor 7 is inserted in the insertion portion 194 so as to be conductively connected.SELECTED DRAWING: Figure 10

    【課題】電動モータに対する導電部材の接続作業を容易に行うことができると共に、導電部材とケースとの間の密閉処理が不要な電動アクチュエータを提供する。【解決手段】電動モータ7を有する駆動部と、駆動部の回転運動を直線運動に変換する運動変換機構部とを備え、運動変換機構部が、駆動部の回転運動を受けて回転するナットと、ナットの内周に配置され、ナットの回転に伴って直線運動するねじ軸とを有する電動アクチュエータにおいて、ケース10と、ケース10と一体に形成された導電部材19とを備え、導電部材19は挿入部194を有し、挿入部194に電動モータ7のモータ端子7cが挿入されて導通可能に接続されている。【選択図】図10
