A link-motion-type vehicle suspension comprising: a link member rotated in a vertical direction, a lower spring seat , an upper spring seat , a coil spring arranged between the lower spring seat and the upper spring seat , an inclination of the lower spring seat being changed in accordance with a position of the link member in the vertical direction, the coil spring comprising: a lower end turn portion which is in contact with the lower spring seat ; an upper end turn portion which is in contact with the upper spring seat ; an effective portion of a cylindrical shape between the lower end turn portion and the upper end turn portion ; and a bowing control portion which is formed in at least one end turn portion of the lower end turn portion and the upper end turn portion , includes a taper portion whose thickness is reduced from an intermediate portion of the end turn portion toward a distal end of a wire along its length, and suppresses bowing of the effective portion by absorbing a change in the inclination of the lower spring seat by the taper portion , characterized in that the lower spring seat includes a first support portion at which a change in height of the first support portion when the link member is rotated in the vertical direction is small, and a second support portion at which the change in height is large, and the taper portion of the bowing control portion extends from the first support portion toward the second support portion . a link member rotated in a vertical direction, a lower spring seat , an upper spring seat , a coil spring arranged between the lower spring seat and the upper spring seat , an inclination of the lower spring seat being changed in accordance with a position of the link member in the vertical direction, the coil spring comprising: a lower end turn portion which is in contact with the lower spring seat ; an upper end turn portion which is in contact with the upper spring seat ; an effective portion of a cylindrical shape between the lower end turn portion and the upper end turn portion ; and a bowing control portion which is formed in at least one end turn portion of the lower end turn portion and the upper end turn portion , includes a taper portion whose thickness is reduced from an intermediate portion of the end turn portion toward a distal end of a wire along its length, and suppresses bowing of the effective portion by absorbing a change in the inclination of the lower spring seat by the taper portion , characterized in that the lower spring seat includes a first support portion at which a change in height of the first support portion when the link member is rotated in the vertical direction is small, and a second support portion at which the change in height is large, and the taper portion of the bowing control portion extends from the first support portion toward the second support portion . a lower end turn portion which is in contact with the lower spring seat ; an upper end turn portion which is in contact with the upper spring seat ; an effective portion of a cylindrical shape between the lower end turn portion and the upper end turn portion ; and a bowing control portion which is formed in at least one end turn portion of the lower end turn portion and the upper end turn portion , includes a taper portion whose thickness is reduced from an intermediate portion of the end turn portion toward a distal end of a wire along its length, and suppresses bowing of the effective portion by absorbing a change in the inclination of the lower spring seat by the taper portion , characterized in that the lower spring seat includes a first support portion at which a change in height of the first support portion when the link member is rotated in the vertical direction is small, and a second support portion at which the change in height is large, and the taper portion of the bowing control portion extends from the first support portion toward the second support portion . <EOS>
