PURPOSE:To reduce a mechanical maximum movable steering angle degree of a rear wheel in accordance with a car speed by providing the second drive means, which moves the first drive means for turning an eccentric cam member and a shaft member along a moving axial line orthogonal with an axial line, in a housing. CONSTITUTION:When an eccentric cam member 50 is turned for housing by the first drive means 63, a lever member 30, engaged with this eccentric cam member 50 in a position eccentrically placed from a turn axial line, performs a swivel motion about it in accordance with a turn amount of the eccentric cam 50. The swivel motion of this lever member 30 is converted into a linear motion in which an operating rod 20, whose one end is turnably engaged, is moved along an axial line. Then, when a shaft member is moved relatively to the housing along a moving axial line, orthogonally intersecting with the axial line of the operating rod 20, by the second drive member 43, that is, lever ratio of the lever member is in a predetermined value, the operating rod is moved in accordance with this predetermined lever ratio to steer a rear wheel. |
