PROBLEM TO BE SOLVED: To set high torsional rigidity around the link axis, and to reconcile restraint of road noise and an improvement in comfortableness by connecting both lower arm via a sub-link having the link axis arranged in the center of gravity of one lower arm or on a straight line passing through the vicinity. SOLUTION: Respective wheel side connecting parts 3a, 4a of plural lower arms 3, 4 are swingably connected to a wheel support member 2 for rotatably supporting wheels 1. One lower arm 4 is formed in an L shape curved inside in the car width direction to the link axis L2 for connecting wheel side and car body side both connecting points P21, P22 for preventing interference with the wheels at steering time. Thus, the center of gravity G of the lower arm 4 exists in a position offset to the lower arm 3 side from the link axis L2. In this case, both lower arm 3, 4 are connected by a sub-link 5, and the link axis L3 of the sub-link 5 is arranged so as to be vertical to the link axis L2 and to coincide with a straight line passing through the center of gravity G.
