Abstract

A strut type suspension (11) is provided with a compression coil spring (12) a lower spring seat (13) an upper spring seat (14) and a shock absorber (15) that passes the inside of the compression coil spring (12). The compression coil spring (12) is disposed at a position offset to the outside of a vehicle with respect to the shock absorber (15). This compression coil spring (12) is mounted to a vehicle body (30) while being compressed between the spring seats (13 14). The compression coil spring (12) has large diameter element wire sections (40a) and small diameter element wire sections (40b). The large diameter element wire sections (40a) are provided in a vehicle inside portion (12a) of the compression coil spring (12). The small diameter element wire sections (40b) are provided in a vehicle outside portion (12b). The element wire diameter (d1) of the large diameter element wire sections (40a) is larger than the element wire diameter (d2) of the small diameter element wire sections (40b).
