Abstract: Provided is an electric actuator, including: a drive part (2); a motion conversion mechanism part (3) configured to convert a rotary motion from the drive part (2) into a linear motion in an axial direction in parallel to an output shaft of the drive part (2); and a lock mechanism part (7) configured to prevent drive by the motion conversion mechanism part (3). The lock mechanism part (7) includes: a rotary motor (64); and a lock member (60), which is driven by the rotary motor (64) so as to be brought into at least any one of a locking state of preventing the drive by the motion conversion mechanism part (3) and an unlocking state of releasing the locking state.

Abstract: An auxiliary power unit equipped wheel support bearing assembly is provided which includes a wheel support bearing assembly and an auxiliary power unit. The auxiliary power unit is of a direct drive design that includes a stator mounted to a stationary ring of the wheel support bearing assembly and a motor rotor mounted to a rotational ring of the wheel support bearing assembly. An entirety of the auxiliary power unit is sized to extend less than an outer peripheral segment of a brake rotor, with the outer peripheral segment defining an area against which a brake caliper is intended to be pushed. The auxiliary power unit is, with respect to an axial direction, sized to be situated between a hub flange of the wheel support bearing assembly and a mounting face of the wheel support bearing assembly for mounting to a vehicle body of a vehicle.

Abstract: A steering device includes tie rods connected to right and left wheels, and rack bars connected to the respective tie rods. The steering device is capable of simultaneously steering the right and left wheels to the right or left of the vehicle, by moving the rack bars to the right or left. A rack bar moving arrangement is provided which is capable of moving the rack bars in opposite directions by the same distance, and rack teeth are arranged along the opposite directions. The rack bar moving arrangement includes a synchronizing gear in mesh with the rack bars, and is configured to convert the movement of one of the rack bars in one of the opposite directions to the movement of the other of the rack bars in the other opposite direction, thereby steering the wheels in opposite directions.
