Abstract: A joint structure includes first and second engagement members, and an elastic member. The first engagement member includes a first body and a first engagement claw. The second engagement member includes a second body and a second engagement claw. The elastic member is disposed between the first and second engagement portions in a circumferential direction. When a relative rotation angle between the first and second engagement members is less than a predetermined angle, the first and second engagement claws are not in direct contact with each other in the circumferential direction, and a rotational force is transmitted through the elastic member while the elastic member is being elastically deformed. When the relative rotation angle is equal to the predetermined angle, the first and second engagement claws are in direct contact with each other in the circumferential direction.

A steering portion includes: a Sun roller that is arranged coaxially around an outer periphery of a middle steering shaft; a plurality of planetary rollers that are arranged around an outer periphery of the Sun roller and contact an outer peripheral surface of the Sun roller; a carrier that supports the plurality of planetary rollers so as to make the planetary rollers rotatable and that is fixed to the middle steering shaft; and a belt that connects the roller to a power generating portion so as to enable a torque to be transmitted to the power generating portion.

Abstract: A reaction force actuator to be used in a steer-by-wire steering device includes an operating-side shaft, a motor, and a friction drive transmission. The operating-side shaft rotates integrally with an operating member that a driver operates. The motor includes a cylindrical motor output shaft disposed coaxially on an outer circumference of the operating-side shaft. The friction drive transmission changes a speed of a rotary motion of the motor output shaft and transmits the rotary motion to the operating-side shaft.
