    摘要： In a method for utilizing a wedge engagement mechanism as means for retaining an output shaft without requiring a large driving power, there is a need for preventing fatigue life of an actuator from being reduced as a result of stress at contacting portions of parts of wedge engagement portions of the wedge engagement mechanism becoming large.In a linear actuator that converts rotary motion of a drive unit for rotation to linear motion through a rotary motion-to-linear motion conversion mechanism, a one-way mechanism is disposed upstream of the rotary motion-to-linear motion conversion mechanism in a rotational drive path, to thereby inhibit, with a small wedge engagement force, the output shaft from being driven by an external force, achieving reduction in the stress at the contacting portions.
