Abstract: In a reverse input cutoff clutch (1), two contact parts (PI1 and PI2) of a first group are respectively disposed closer to a first reference line (RL1) than two of a fifth contact part (PO1), a sixth contact part (PO2), a seventh contact part (PO3), and an eighth contact part (PO4), and two contact parts (PI3 and PI4) of a second group are respectively disposed farther from the first reference line (RL1) than the other two of the fifth contact part (PO1), the sixth contact part (PO2), the seventh contact part (PO3), and the eighth contact part (PO4).

Abstract: An actuator with reverse input blocking clutch has a function of switching the reverse input blocking clutch to a state in which torque can be transmitted between an input member and an output member, in a state in which reverse torque is input to the output member from an output-side mechanism, by applying torque to the input member by an actuator in an opposite direction to a direction of the reverse torque, and then by giving an instruction to the actuator to apply torque having a magnitude smaller than a magnitude of the reverse torque to the input member in the opposite direction, transmitting the reverse torque to the input member.

Abstract: A steering device includes: a variable actuator capable of changing an angle ratio between a steering angle of a steering wheel and a turning angle of a turning wheel; a steering auxiliary mechanism arranged between the variable actuator and the turning wheel to apply steering auxiliary force to a steering mechanism; a torque angle sensor to detect steering torque to be inputted into the steering mechanism. The steering auxiliary mechanism is driven such that the steering auxiliary force in accordance with the steering torque is generated, and, when an avoidance instruction is inputted, an automatic steering control is performed to drive-control the steering auxiliary mechanism so as to run at the turning angle specified by steering position instruction to be inputted. The angle ratio of the variable actuator is adjusted so as to suppress reaction force to be transmitted to the steering wheel by performing the automatic steering control.
