Abstract
A cam follower includes an oval rotational body which is rotationally supported on a fixed pin, and in which an outer circumferential shape thereof is an oval, a long axis of the oval is longer than a width of the cam groove, and a short axis of the oval is shorter than the width of the cam groove, the oval rotational body being biased and being rotated by a biasing spring in one direction about the fixed pin. As a consequence, when a steering wheel is in a neutral position, the outer circumferential surface of the cam follower comes into contact with both side surfaces of the cam groove in the width direction of the cam groove and gaps therebetween can be eliminated. As a result, neutral stability of the steering wheel and steering feeling during straightforward traveling are improved.
