  • Patent number: 11865886
    Abstract: A suspension includes a coil spring, a shock absorber, a spring seat, and at least three strongly pressing parts. The coil spring elastically receives vertical movement of a wheel relative to a vehicle body. The shock absorber damps the vertical movement. The spring seat is provided in the shock absorber. The sprint seat supports an axial end of the coil spring. The coil spring is in direct or indirect contact with the spring seat over a predetermined distance from an end to a point of separation of the coil spring. The strongly pressing parts are provided in the spring seat. The strongly pressing parts apply contact pressures higher than contact pressure applied by other part, to the coil spring. The point of separation is disposed at a region that is between the strongly pressing parts and has the largest opening angle about an axial center of the shock absorber.
