The present invention is directed to a helical compression spring for a vehicle suspension to be compressed between an upper seat and a lower seat. The spring is formed to provide an end coil center line connecting the centers of an upper end coil and a lower end coil to be offset to a coil axis of a body portion of the spring. A pitch of the lower end coil is set to tilt a lower end plane of the spring at a first predetermined angle to the lower seat in a direction for shortening the longitudinal length of one side of the spring closer to the end coil center line than the coil axis, in an unloaded state of the spring, and/or a pitch of the upper end coil is set to tilt an upper end plane of the spring at a second predetermined angle in a direction for shortening the longitudinal length of the other side of the spring closer to the coil axis than the end coil center line, in the unloaded state of the spring.
A helical compression spring for a vehicle suspension to be compressed between an upper seat and a lower seat, said spring being formed to provide an end coil center line connecting the centers of an upper end coil and a lower end coil of said spring to be offset to a coil axis of a body portion of said spring,
A strut type vehicle suspension comprising a strut mounted at the upper end thereof on a vehicle body for supporting a wheel, a lower seat fixed to said strut, an upper seat mounted on said vehicle body, and a helical compression spring mounted between said lower seat and said upper seat, with said strut enclosed in said spring,
