PROBLEM TO BE SOLVED: To suppress generation of lateral force in a general-purpose coil spring.SOLUTION: A coil sparing is sued in a suspension of a vehicle. The coil sparing has a closed end structure where each terminal is formed into a flat shape. Each section with at least one pitch from each terminal is a gradual change section whose coil diameter becomes larger toward a center part of the coil spring. An increase width of the coil diameter per pitch in the gradual change section is made smaller than a diameter of an element wire of the coil spring.SELECTED DRAWING: Figure 1

    【課題】 汎用性が必要されるコイルばねにおいて横力の発生を抑制する。【解決手段】 コイルばねは、車両のサスペンションに用いられる。このコイルばねでは、各端末が平坦に形成されたクローズドエンドの構造を有する。各端末から少なくとも1ピッチ分の各区間は、コイルばねの中央部に向かうにつれてコイル径が増大する徐変区間となっている。徐変区間における1ピッチあたりのコイル径の増大幅は、コイルばねの素線径よりも小さい。【選択図】 図1
