A coil spring (2) for use in a link-motion-type suspension (1) includes a lower end turn portion (20), an upper end turn portion (21), and an effective portion (22) of a cylindrical shape between the lower end turn portion (20) and the upper end turn portion (21). Further, the coil spring (2) includes a bowing control portion (100) including a taper portion (25) formed in at least one end turn portion of the lower end turn portion (20) and the upper end turn portion (21). The taper portion (25) has a shape whose thickness is reduced from the middle of the end turn portion (20) toward a distal end (4X) of a wire (4) along its length, and bowing of the effective portion (22) is suppressed by absorbing a change in the inclination of a spring seat (10) by the taper portion (25) .
