An axle that rotatably supports a wheel is elastically coupled to trailing arms of a motor vehicle via an upper connecting point and first and second lower connecting points, where the trailing arms are elastically coupled to a body of the vehicle. The first and second lower connecting points are positioned lower than the upper connecting point and are mutually arranged to open a gap in a front-to-rear direction of the vehicle. The first and second lower connecting points have elastic members and are arranged so that principal elastic axes of their respective elastic members intersect at a location that is outside, in the lateral direction of the vehicle, of a grounding point of the wheel. In this manner, the running stability can be increased without relying on the rigidity of the elastic members, resulting in increased freedom in design of the elastic members.
