PURPOSE:To reduce the space of tire housing by providing means for limiting the steering angle of rear wheel with correspondence to the bound condition of rear wheel thereby preventing considerable bound of rear wheel under large steering condition. CONSTITUTION:The rear wheel steering system will steer the rear wheels 34a, 34b by means of a hydraulic actuator 31 to be driven through control of working oil in the left/right pressure chambers 37, 38 by means of a solenoid valve 60. Changeover of direction of solenoid valve 60 is executed through a controller 61. Here, a solenoid valve 64 for switching communication and interruption of oil paths 65, 66 to said chambers 37, 38 is provided. If the bound stroke S of rear wheel is lower than predetermined level under travel with car speed V lower than a setting level, said valve 64 is closed to alloy steering of rear wheel while if it is higher than predetermined level, said valve 64 is opened to steer the rear wheel. |
