A stay structure includes a stay main body having a ball-like portion at one end, and a base member configured to hold the ball-like portion. The base member includes a first base portion and a second base portion detachably attached to first base portion. The first base portion is provided with an upwardly protruded peripheral wall portion. The peripheral wall portion is divided into a plurality of divided wall pieces, and is provided with a recessed groove portion capable of holding an external periphery of the stay main body. The second base portion is provided with a pedestal portion fitted to the peripheral wall portion. The pedestal portion has at its upper surface a recessed curved surface on which the ball-like portion is swingably disposed. The ball-like portion is swingably held by and between the inner surface of the peripheral wall portion and the curved surface of the pedestal portion.

Stay structure

A rear end of a torsion bar is fixed to a distal portion of a spring plate so that the rear end of the torsion bar is in a position other than front to rear direction of a cross member. Thus, when a load is applied to the suspension system in the front to rear direction, the spring plate elastically deforms in this direction. Therefore, the suspension system can prevent the torsion bar from directly contacting the cross member. Also, the suspension arm has two arm portions each of which is supported by two pivot portions. The body has sufficient rigidity against a load applied in the lateral direction thereof. When a load is applied in the front to rear direction, the spring plate elastically deforms, thereby moving the suspension system in this direction. When a load is applied in the vertical direction of the body, the torsion bar twists. With this reaction force, a suspension force takes place and the spring plate bends. Thus, an excessive bending force is not applied to the torsion bar.
