PROBLEM TO BE SOLVED: To provide a suspension coil spring capable of reducing an amount of bending of a trunk in a compression state, and friction which is generated on a shock absorber, and a strut type suspension device comprising the suspension coil spring.SOLUTION: A suspension coil spring is attached between an upper side seating and a lower side seating on a strut type suspension device for vehicle. The suspension coil spring comprises: an upper end coil which is seated on the upper side seating; a spring effective part having one or more rolls formed so that a portion where curvature is the largest is positioned on outside of the vehicle, in an attachment state; and a lower end coil which contacts the lower side seating and is seated on the lower side seating at a lower side contact point positioned on outside of the vehicle of the lower side end coil central point.
【課題】圧縮状態における胴曲がり量及びショックアブソーバに生じるフリクションを低減可能な懸架コイルばね、及びこの懸架コイルばねを備えたストラット型懸架装置を提供すること。【解決手段】自動車用のストラット型懸架装置における上側座と下側座との間に装着される懸架コイルばねであって、前記上側座に着座する上側座巻と、装着状態において、曲率の最も大きい部位が車外側に位置するように形成された巻きを1つ以上有するばね有効部と、下側座巻中心点より車外側に位置する一箇所の下側接触点で前記下側座に接触して着座する下側座巻と、を有する懸架コイルばね。【選択図】図1
