Abstract: An alignment adjustment device includes an actuator that is fixed to a vehicle body side support member and that is connected to an outer peripheral surface of a hub carrier so as to rotate the hub carrier. An intersection between a first axis and a second axis and an intersection of a universal joint are both positioned inside a wheel, and the intersection of the universal joint is inside the hub carrier.

Abstract: Left and right actuators (14) for a vehicle are provided that include a first housing (31) and a second housing (32) connected in a direction of an axis (L), a coupling flange (31a) of the first housing (31) and a coupling flange (32a) of the second housing (32) being connected by a plurality of bolts (35) disposed at equal intervals on a circumference having the axis (L) as the center, and since a component mounting part via which a stroke sensor (102) is mounted on the second housing (32) is provided at an intermediate position between two bolts (35) of the plurality of bolts (35) or at a position of any one bolt (35), the stroke sensors (102) of the left and right actuators (14) can be disposed at positions that are mirror-symmetric relative to a central plane (P) of a vehicle body while reducing the number of components by using in common for each of the left and right actuators (14) the second housing (32) on which the stroke sensor (102) is mounted.

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.

Abstract: A telescopic actuator includes a motor, an input flange rotated by the motor, a male screw member coupled to the input flange, a female screw member threadedly engaged with the male screw member, an output rod coupled to the female screw member, the output rod being moved in an axial direction thereof to output a thrust force when the input flange is rotated, and a housing inside which the male screw member and the female screw member are accommodated. The input flange is supported by the housing such that a relative movement of the input flange with respect to the housing is allowed in a radial direction but restricted in the axial direction.

Abstract: A telescopic actuator includes a housing, an output rod which is slidable in an axial direction with respect to the housing, at least two slide bearings via which the output rod is supported by the housing, and a stopper disposed between the two slide bearings. The stopper regulates a moving end position of the output rod.

Abstract: A reduction gear includes a rotatable carrier, a ring gear rotatably fitted in an offset supporting hole in the carrier, and first and second sun gears having first and second outer teeth meshed with first and second inner teeth of the ring gear, respectively. The rotation of the carrier is reduced in speed and outputted as relative rotation of the first and second sun gears. Thus, it is possible to secure a large reduction ratio although in a small structure having a small number of components. Also, it is possible to change the reduction ratio by a slight design change of the number of teeth in one or both of the outer teeth of the first and second sun gears, thereby improving the versatility.
