PURPOSE:To eliminate the possibility of occurrence of a shearing force caused by a longitudinal force by coupling both ends of main arm laid crosswise of a vehicle and formed of a leaf spring, and both ends of an auxiliary arm laid obliquely or longitudinally of the vehicle and having a rigidity higher than that of the main arm, respectively to specific parts. CONSTITUTION:A suspension arm 10 constituting a vehicle suspension device 12, includes a main arm 14 and an auxiliary arm 16. Further, the main arm 14 is formed of a leaf spring, having its one end coupled to a vehicle body 34, rotatably about an axis extending vertically, and its outer end coupled to a wheel support member 18. Further, the auxiliary arm 16 is laid obliquely or longitudinally of the vehicle body 34, having a rigidity which is higher than that of the main arm, and having its one end coupled to the main arm 14, rotatably about an axis extending vertically, and the other end coupled to the vehicle body 34 through the intermediary of a resilient cylindrical bushing 44 whose axis extends vertically. |
