Abstract
To provide a compression spring formed of an elastic body made from a resin or rubber which is capable of maintaining its shape upon deformation without the use of any supporting member, thereby always ensuring a specific load-deformation characteristic. A compression spring of the present invention includes a cylindrical spring main body, wherein compression energy generated when the compression spring is pressed in the radial direction is absorbed by elastic deformation of the cylindrical spring main body. In this compression spring, a base having a flat bottom surface swelled along a plane perpendicular to the pressing direction is formed on the pressing force receiving side of the spring main body. Furthermore, a reinforcing wall for connecting the swelled portion of the base to a side portion of the cylindrical spring main body is formed integrally with the spring main body.
