Abstract:
A helical compression spring mounted on a vehicle body to be compressed between an upper seat and a lower seat, a coil axis of said spring is substantially curved at a predetermined radius of curvature in an unloaded state of said spring, with opposite end planes of said spring formed to be seated on said upper seat and lower seat, respectively, and a pitch of a lower end coil of said spring is set to tilt the end plane of said lower end coil at a first predetermined angle to said lower seat in the direction for shortening the longitudinal length of said spring at the inside of the curvature, and the center of the end plane of said upper end coil is offset to the center of the end plane of said lower end coil in the direction of the inside of the curvature.
