PROBLEM TO BE SOLVED: To suppress toe angle change due to deformation of a vehicular suspension device.SOLUTION: A vehicular suspension device includes an axle carrier having an axle supporting a steering wheel as rotatable, a first lower link member and a second lower link member which are lower than the axle and connect a body side member and the axle carrier respectively, a steering rack member which steers the steering wheel and is fitted to the body side member, and a steering control device which drives and controls an actuator for driving and controlling the steering rack member. One of the first lower link member and the second lower link member is set as the lateral force supporting link member which has more sharing of the lateral force compared with the other, a king pin axis, which sets the intersection of the first lower link member and the second lower link member as a lower pivot pint, is set to pass the inside of a tire ground contact surface, and the bush rigidity at the body side fitting position of the lateral force supporting link member and the steering rack member is set so as to suppress the toe angle change of the steering wheel due to deformation. |
