摘要： A torque is transmitted from a steering assistance motor to a steering shaft via a gear. The first rotation restraining element, which is radially deformed by being sandwiched between the outer circumference of the steering shaft and the inner circumference of the gear, exerts a radial force corresponding to the radial deformation on the steering shaft and the gear, to generate a torque based on friction for restraining the relative rotation between the shaft and gear. The restraining torque generated based on the deformation of the first rotation restraining element is smaller than the breaking torque of the second rotation restraining element, which is fitted to the steering shaft and the gear via clearances so as to restrain the relative rotation between the shaft and gear.
