  • Patent number: 9416836
    Abstract: A supporting projection is formed on a resin base plate on which a seat winding portion of a coil spring is fitted. The supporting projection has such rigidity that a distal end portion does not deflect against a spring force applied radially inwards from the seat winding portion of the coil spring. On the other hand, an elastic deflectable area which deflects elastically by the spring force applied radially outwards from the seat winding portion of the coil spring is formed in an area which extends from a proximal end to the distal end portion of the supporting projection.
