Electric Actuator

Abstract

To provide an electric actuator which simplifies the structure of the electric actuator by integrating the sliding seat of a sliding unit with a nut member, and then facilitates assembly to reduce combination tolerances, thereby improving the operating accuracy of the electric actuator. [Solution] The electric actuator (50) comprises a cylindrical housing (52), a sliding unit (54), and a threaded shaft (56). The cylindrical housing (52) has at least one guide groove extending vertically in its bore wall. The sliding unit (54) comprises a rotation limiting member (72), a nut member (70), and an output shaft. The rotation limiting member (72) has at least one guide mass that fits into a first end of the nut member (70) and is used to fit into the guide groove of the cylindrical housing (52). One end of the output shaft (74) fits into a second end of the nut member (70). The threaded shaft (56) is connected to the nut member (70) in a relatively movable manner.
