This electric actuator is provided with an electric motor (8a), a pressing unit (20), a plate spring (21), a booster unit (22), and a booster ratio conversion unit (23). The booster unit (22) is configured to include a plurality of levers (29) that swing around roller (28), and is displaced in a direction in which a pressing plate (30) constituting the pressing unit (20) protrudes from a cylinder space (6a). The booster ratio conversion unit (23) displaces each roller (28) in the circumferential direction of each lever (29), thereby altering the booster ratio. |
