PROBLEM TO BE SOLVED: To provide a spring of a suspension for a vehicle for reducing a load and vibration, and to provide a spring of a suspension for a vehicle for improving rigidity and nonlinearity of the spring.SOLUTION: A spring of a suspension for a vehicle includes a spring, which is supported and disposed between a lower seat installed on a suspension and a vehicle body and which is formed in a shape of a bellows type tube that is hollow inside to give elastic force. The spring is manufactured from materials with different qualities and is composed of an inner layer and an outer layer. The inner layer and the outer layer are respectively composed of materials with different qualities from each other. The inner layer is formed of an elastic material, while the outer layer is formed of a high rigidity material. Nonlinear characteristics are imparted to the spring by forming a groove-like slit on an outer side of the spring. |
