摘要： 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).

摘要： A knee action type suspension device (11) is provided with an arm member (20), a coiled compression spring (21), and a shock absorber (24). The arm member (20) is supported by a pivot (31) so as to be capable of pivoting in the vertical direction, the pivot (31) being provided to an arm mounting section (30). The coiled spring (21) is disposed between spring seats (22, 23). The coiled spring (21) extends and retracts between a fully rebound state and a fully bumped state according to the magnitude of a load applied to the vehicle body. The wire (40) of the coiled spring (21) has a large-diameter wire section (40a), a small-diameter wire section (40b), and a wire diameter changing section (40c). The large-diameter wire section (40a) is provided to a first portion (21a) of the coiled spring (21), the first portion (21a) being located on the side of the coiled spring (21) which is closer to the pivot (31). The small-diameter wire section (40b) is provided to a second portion (21b) of the coiled spring (21), the second portion (21b) being located on the side of the coiled spring (21) which is farther from the pivot (31). The wire diameter (d1) of the large-diameter wire section (40a) is greater than the wire diameter (d2) of the small-diameter wire section (40b).

摘要： A coiled spring for a suspension device includes a lower seat winding section (42), an upper seat winding section (44), and a helical effective section (45) which is formed between the seat winding sections (42, 44). The lower seat winding section (42) includes: a first portion (42a) which is always in contact with a lower spring seat irrespective of a load; and a second portion (42b) which comes into contact with and separates from the lower spring seat according to a load. The wire diameter at the second portion (42b) is greater than the wire diameter at the first portion (42a) and is greater than the average wire diameter at the effective section (45). The upper seat winding section (44) includes: a third portion (44a) which is always in contact with an upper spring seat irrespective of a load; and a fourth portion (44b) which comes into contact with and separates from the upper spring seat according to a load. The wire diameter at the fourth portion (44b) is greater than the wire diameter at the third portion (44a) and is greater than the average wire diameter at the effective section (45).
