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.
