摘要： A coil spring includes a wire formed of spring steel shaped to be helical, and is compressed between an upper spring seat and a lower spring seat. The coil spring includes an upper portion and a lower portion. A positive pitch winding end portion is formed on the upper portion of the coil spring. A terminal-point-strong-abutting-portion is formed at a distal end of the winding end portion. The terminal-point-strong-abutting-portion is in contact with the upper spring seat at one point at a position deviated to an inner side of a vehicle with respect to a coil central axis. On the lower portion of the coil spring, an end turn portion which contacts the lower spring seat is formed at a position deviated to an outer side of the vehicle.
