1. A suspension to be applied to a vehicle, the suspension comprising:
a coil spring configured to elastically receive vertical movement of a wheel relative to a vehicle body of the vehicle;
a shock absorber configured to damp the vertical movement;
a spring seat provided in the shock absorber, the spring seat supporting an axial end of the coil spring, the coil spring being in direct or indirect contact with the spring seat over a predetermined distance from an end of the coil spring to a point of separation of the coil spring; and
at least three strongly pressing parts provided in the spring seat, the strongly pressing parts being configured to apply contact pressures higher than contact pressure applied by another part of the spring seat, to the coil spring, wherein
the point of separation is disposed at a region between the strongly pressing parts, the region having the largest opening angle about an axial center of the shock absorber, among regions between the strongly pressing parts that are adjacent to each other,
wherein a load that is applied by the coil spring is biased to a side on which the strongly pressing parts are more densely disposed on the spring seat.
