Abstract
A ring gear of a planetary reduction gear is screwed into an inner peripheral surface of a first housing through an opening thereof, while the thrust-receiving flange of a screw feed mechanism is held by the locknut screwed into an inner peripheral surface of a second housing through an opening thereof. In addition, the locknut and the ring gear face each other in an axial direction with a slight gap provided therebetween when the openings, respectively, of the first and second housings are connected to each other in the axial direction. Accordingly, even if the threaded connection of any one component of the locknut and the ring gear is loosened, the one component is prevented from moving by the other component.
