Patent ID: 8201657

Claim:
A steering apparatus for a vehicle, having: a first rotational member that receives a steering torque from a steering wheel; a second rotational member that receives the steering torque from the first rotational member and transmits the steering torque to a steered wheel; a cam follower that is provided at an end surface of one of the first rotational member and the second rotational member and provided in a position displaced with respect to a rotational shaft of the one of the rotational members; and a cam groove that is formed in an end surface of the other of the first rotational member and the second rotational member and extends in a direction perpendicular to a rotational shaft of the other of the rotational members, wherein the rotational shaft of the first rotational member is displaced with respect to the rotational shaft of the second rotational member, and in a state in which the first rotational member is arranged above the second rotational member, the cam follower engages with the cam groove wherein the cam follower includes a fixed pin that is fixed to the one of the rotational members; an oval rotational body which is rotationally supported on the 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; and biasing means for biasing the oval rotational body to rotate the oval rotational body in one direction of circumferential directions of the fixed pin.
