SUSPENSION COIL SPRING AND STRUT-TYPE SUSPENSION DEVICE

摘要

A suspension coil spring mounted between an upper end and a lower end of a vehicle strut-type suspension device comprises a coil spring body having an upper end turn secured at the upper end and a lower end turn secured at the lower end when the suspension coil spring is mounted. In the mounted state, the upper end and the upper end turn are substantially in contact with each other at two or more upper contact points on the upper end turn. In the mounted state, the lower end and the lower end turn are substantially in contact with each other at one lower contact point on the lower end turn. The two upper contact points are disposed so as to be separated from each other in the upper end turn in the front and back direction of a vehicle. The one lower contact point is disposed at a position in the vehicle outside direction relative to a plane passing through the two upper contact points in the lower end and being parallel to the end turn center axis.
