A coil spring (2) according to one embodiment includes a lower end turn portion (20) which is in contact with a lower spring seat (10), an upper end turn portion (21) which is in contact with an upper spring seat (11), and an effective portion (22) between the lower end turn portion (20) and the upper end turn portion (21). The coil spring (2) is cylindrical about an axis of the effective portion (22) in its free shape which is not compressed. Further, with respect to a coordinate system in which a force line (FL) is assumed as a Z-axis, the coil spring (2) is cylindrical with a constant pitch in a direction along the Z-axis in its compressed shape which is compressed to a specified height.
