Abstract
A spring damper for absorbing vibration of a double coil spring is made of elastic material and composed of a cylindrical body, outer-wall convex portions, and inner-wall convex portions. The spring damper is arranged in an annular space formed between an outer coil spring and an inner coil spring of the double coil spring, so that the outer-wall convex portions push the outer coil spring in a radial outward direction and the inner-wall convex portions push the inner coil spring in a radial inward direction. Longitudinal ends of the cylindrical body are prevented from being hooked by spring wires of the outer or inner coil spring, when the double coil spring is expanded and compressed.
