<p>PROBLEM TO BE SOLVED: To provide a space-saving linear actuator in which an upper part yoke and a bottom yoke do not drop off as a result of a strong impact. SOLUTION: The linear actuator is provided with a fixing part 20 comprising the upper part yoke 25 having a center yoke 24 and the bottom yoke 21a having a recessed part 200 formed at part of a bottom and a fitting hole 201 for fitting the center yoke 24 into the recessed part 200, and a movable part 30 which relatively moves in the axial direction of the fixing part 20. In the state where the center yoke 24 and the bottom yoke 21a are fitted, a spring 26 for locking is mounted between the tip part of the center yoke 24 projected from a fitting hole 201 and a step part 202 formed at a boundary between the bottom surface of the recessed part 200 and the plane of the bottom yoke.</p> |
