Upper suspension members have axle side mounting portions mounted on a wheel carrier with an axle on which a dirigible wheel is rotatably supported. The axle side mounting portions are disposed on opposite sides of the center of the wheel and a middle portion which is substantially equidistant from the side mounting portions is displaced from the center of the dirigible wheel in the longitudinal direction of the vehicle body.
