PURPOSE:To prevent a coil spring from moving in radial direction by providing a vibration-proof seat fitted into the coil spring for vehicle suspension with projections engaged with internal sides of the coil spring. CONSTITUTION:A vibration-proof rubber seat 6 has a conical stand-shaped convex part 6a on the underside face of a flat part 6e, and a peripheral face of part 6a forms a taper face. The plural number of triangular projections 6c, outer faces of which run parallel with the inner side of a coil spring 5, are provided on said taper face intermittently in the peripheral direction. Further grooves 6b are radially provided on the upper face of said seat 6, while a hole 6d is made in the center of the seat 6. Due to the hole 6d, even if the upper end of the coil spring 5 is separated from the flat part 6e of the seat 6 because of an incoming vibration, the spring 5 does not move in radial direction relative to the seat. |
