PROBLEM TO BE SOLVED: To secure the smooth action of an actuator for controlling a toe angle of a rear wheel without applying a large change to a constituent. SOLUTION: The rear suspension device is provided with: an upper arm 6 arranged at a front side more than an axle 3 as a lateral arm; a front side lower arm 7 arranged at a front side more than the axle; and a rear side lower arm 8 arranged behind the axle and connected with a suspension spring S. In order to turn a hub carrier 4 to actively control a toe angle of the rear wheel, a toe control arm 9 which is expandable and contractible by the actuator 26 is connected to the hub carrier, and a connection link 21 is interposed between a rear side lower arm and the hub carrier so that the hub carrier can be turned in a required range of an angle making a virtual king pin shaft K for connecting respective connection parts of the upper arm and the lower side lower arm relative to the hub carrier as a center.
