PURPOSE:To reduce the max. mechanical movable steering quantity of a rear wheel according to the car speed by moving a movable block member in straight line form through an eccentric cam means by the first driving means and changing the direction of the above-described rectilinear movement for a fixed block member by the second driving means. CONSTITUTION:An operating rod 20 for steering rear wheels is supported in shiftable manner on a leg cylinder part 10A2 projecting to both the lower sides of a housing 10 formed integrally with a car body, and a cylindrical member 30 which is turned through the meshing of a pinion 42 and a worm wheel 36 by the second motor is supported on the cylindrical part 10A1 of the housing 10, and an eccentric cam shaft 50 which is turned through the meshing between a pinion 62 and a worm wheel 54 by the first motor 60 is supported on an upper housing 10B. A movable block member 70 is supported in slidable nanner on a guide rod 39 installed on the cylindrical member 30, and an eccentric pin 56 is engaged with a groove 70A on the upper side of the movable block member 70, and a driving projection 72 on the lower side is engaged with a groove 80A formed on a fixed block member 80 on the operating rod 20. |
