Abstract: An electric actuator includes a case, an electric motor 5 built in the case, and a motion conversion mechanism 4 configured to convert a rotary motion of the electric motor 5 into a linear motion. The electric motor 5 is fixed to the case (gear case 10) at a first end in an axial direction of the electric motor 5, and the electric actuator is provided with a first elastic member 50 between an outer peripheral surface of the electric motor 5 and an inner peripheral surface of the case (motor case 60) at a second end of the electric motor opposite to the first end fixed to the case (gear case 10).

Abstract: A wheel bearing device includes a wheel bearing supported by a knuckle; a hub ring having a boss portion; a second constant-velocity joint; and a first constant-velocity joint. The second constant-velocity joint includes an outer ring rotatably supported by the wheel bearing, and an inner ring coupled to the boss portion of the hub ring. The first constant-velocity joint includes an outer ring coupled to the outer race of the second constant-velocity joint, and an inner ring coupled to a drive shaft. The knuckle supports a pair of camber angle-adjusting linear motion actuators, and a pair of toe angle-adjusting linear motion actuators.

Abstract: The power transmission device includes an input shaft that rotates about its axis together with a vehicle wheel. A driving gear is arranged coaxially with the input shaft so as to rotate about the axis of the input shaft together with the input shaft. A driven gear meshes with the driving gear, and configured to transmit a rotational force to an output shaft connected to a regenerative energy converter. A wheel bearing for the vehicle wheel supports the input shaft such that the input shaft is rotatable about its axis relative to the driven gear.
