動式アクチユエータ。[Claims for Utility Model Registration] (1) An outer race that is provided integrally with the motor rotor and has an inner thread formed on the inner surface of the hollow part, and an outer thread that meshes with the inner thread. In a motor-driven actuator comprising a lead screw movably provided in a hollow part, the outer race is made of a material having excellent sliding properties and a coefficient of thermal expansion similar to that of the metal material forming the lead screw. The bearing side end of the outer race is fixed by heat caulking to the inner ring of a bearing device that rotatably supports the motor rotor, so that both members rotate together. A motor-driven actuator characterized by: (2) The motor-driven actuator according to claim 1, which is a registered utility model, characterized in that a polyphenylene sulfide resin containing a fluororesin resin is used as the resin material with excellent sliding properties. . (3) Utility model registration claim 1, characterized in that one end of the outer race is supported by a bearing device and the other end of the outer race is pivotally supported by a plain bearing. Motor-driven actuator as described.
