To relax shock that is generated when power of an electric motor is lost.SOLUTION: An electric actuator (10) is provided with a corotation restricting mechanism (50) that inhibits corotation of a rotating part (29) and a direct-acting part (30) which is caused by rotation of the rotating part (29) in an increasing direction (R3) of braking force and rotation of the rotating part (29) at torque less than predetermined torque in a decreasing direction (R4) of the braking force, and permits corotation of the rotating part (29) and the direct-acting part (30) which is caused by rotation of the rotating part (29) at torque more than the predetermined torque in the decreasing direction (R4).SELECTED DRAWING: Figure 1
【課題】電気モータが動力を喪失したときに発生する衝撃を緩和する。【解決手段】電動アクチュエータ(10)は、制動力の増加方向(R3)への回転部(29)の回転と、制動力の減少方向(R4)への所定トルク未満の回転部(29)の回転とに伴う、回転部(29)と直動部(30)との供回りを阻止し、減少方向(R4)への所定トルク以上の回転部(29)の回転に伴う、回転部(29)と直動部(30)との供回りを、許容する供回り制限機構(50)を備えている。【選択図】図1
