Abstract: An end turn portion of a coil spring includes a first portion, a second portion, and a third portion. The first portion is always in contact with a spring seat irrespective of the magnitude of a load applied to the coil spring. The second portion contacts the spring seat when the load applied to the coil spring is large, and is separated from the spring seat when the load is small. The third portion is always separated from the spring seat irrespective of the magnitude of the load. An insulating sheet made of a material having rubber elasticity is attached to a lower surface of a wire at the end turn portion by means of adhesive bonding. The insulating sheet is provided on a lower surface of a region including at least the second portion.

Abstract: 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.
