Abstract: A coil spring includes a wire 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.

Abstract: A lower-side spring-receiving member of a suspension device, receiving a suspension spring structured to have a rising section at a lower side of the suspension spring, having a partially annular shape and including: a base end portion arranged at one end of the lower-side spring-receiving member wherein an end of the suspension spring is inserted into the base end portion; a slope portion arranged at the other end of the lower-side spring-receiving member and having a thickness in a cross-sectional view varying so as to follow a shape of the rising section of the suspension spring; and a holding portion that is arranged between the base end portion and the slope portion and holds the suspension spring, wherein the slope portion has a recess portion (Nk) formed on its bottom-surface; the recess portion includes a ridge portion is formed in a substantially mountain shape in a cross-sectional view taken along a radial direction of the partially annular shape and may be or may not be in contact with a mounting surface when no spring load of the suspension spring is applied.
