PURPOSE: To strengthen rigidity in the cross direction of a leaf spring by providing reinforcing fiber built in the middle of molding the leaf spring larger in elastic coefficient than glass fiber and arranging it along a neutral axis of curvature of a cross-section of the leaf spring. CONSTITUTION: A leaf spring 1 for a suspension of a vehicle is manufactured by molding of plastics strengthened by glass fiber. Reinforcing fiber 2 is built in during molding and materially arranged along a neutral axis A of curvature of the leaf spring 1. This reinforcing fiber 2 has an elastic coefficient extensively larger than glass fiber and is normally made of carbon fiber. Consequently, it is possible to strengthen rigidity in the cross direction of the leaf spring. |
