To prevent falling of a coil spring from a spring holding portion, to prevent falling of an elastic supporting member from the coil spring in being assembled in the coil spring, and to easily assemble the elastic supporting member to the coil spring.SOLUTION: An elastic supporting member 10 disposed between an end coil portion 4 of a coil spring 2 and a spring seat 5 has a main body portion (12) including a partially annular spring supporting face 11 supporting the end coil portion 4, and a spring holding portion 15 forming an annular shape in cooperation with the main body portion to define an insertion hole 16 to which the end coil portion 4 is inserted, and holding the end coil portion 4. The spring holding portion 15 includes an elastic wall body 21 elastically closely kept into contact with the end coil portion 4 from a side opposite to the spring supporting face 11 in an assembled state to the coil spring 2, and opposed to the end coil portion 4 with a clearance at least at one side of the end coil portion 4.SELECTED DRAWING: Figure 10
【課題】コイルスプリングのスプリング保持部からの脱落及び、コイルスプリングへの組付状態における弾性支持部材のコイルスプリングからの脱落を防止し、且つ弾性支持部材のコイルスプリングへの組付を容易にする。【解決手段】コイルスプリング2の座巻部4とスプリングシート5との間に介装される弾性支持部材10は、座巻部4を支持する部分円環状のスプリング支持面11を含む本体部(12)と、座巻部4を挿通させる挿通孔16を画定すべく本体部と協働して環状をなし、座巻部4を保持するスプリング保持部15とを有する。スプリング保持部15は、コイルスプリング2への組付状態において、スプリング支持面11と相反する側から座巻部4に弾発的に圧接し、座巻部4の少なくとも一方の側方において座巻部4に対して間隔をおいて対峙する弾性壁体21を含む。【選択図】図10
