PROBLEM TO BE SOLVED: To provide a suspension coil spring that enables reduction of the amount of buckling in the compressed state and friction of a shock absorber, and a strut type suspension device including the suspension coil spring.SOLUTION: A suspension coil spring mounted between an upper seat and a lower seat in a strut type suspension device for an automobile includes: an upper coil end that is seated on two upper contact points arranged to separate from each other in the longitudinal direction of the automobile so as to substantially come into contact with the upper seat; a spring effective portion having one or more turns formed so that a portion with the largest curvature is located on the vehicle outer side in the mounted state; and a lower coil end that is seated on one lower contact point located on the vehicle outer side from the central point of the lower coil end so as to substantially come into contact with the lower seat. The two upper contact points of the upper coil end of the suspension coil spring are formed on a line segment parallel with a line segment extending in the longitudinal direction of the automobile.SELECTED DRAWING: Figure 1

    【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、前記自動車の前後方向に離間して設けられた二箇所の上側接触点で実質的に前記上側座に接触して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実質的に前記下側座に接触して着座する下側座巻と、を有し、前記上側座巻は、前記二箇所の上側接触点が、前記自動車の前後方向に延在する線分に平行な線分上に形成されている懸架コイルばね。【選択図】図1
