CONSTITUTION: A rear wheel suspension device of a fuel cell vehicle comprises a cross member(1), an in-wheel motor case(2), an upper arm(3), a lower arm, a trailing arm(5), a coil spring(6), a shock absorber(7), a brake caliper(8), and a hub bearing. The cross member is installed to locate both sides of a vehicle body. The in-wheel motor case is installed with space between the both side of the cross member. One sides of the upper arm and the lower arm are coupled with the cross member and the other sides are installed in the in-wheel motor case. One side of the trailing arm is coupled with the in-wheel motor case and vehicle body portion in the front of the cross member. The lower side of the coil spring is installed in the trailing arm and the other side is connected to a vehicle body. The lower side of the shock absorber is coupled with the motor case and the other side is connected to a vehicle body. The brake caliper is coupled with the in-wheel motor case. The hub bearing is coupled with the exterior of the in-wheel motor case.
