Title:
COMPRESSION COIL SPRING
Document Type and Number:
Japanese Patent JP3938766
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a compression coil spring for a shock absorber, reducing sliding resistance generated between a cylinder and a piston of the shock absorber without increasing the size of a vehicular suspension.
SOLUTION: To achieve the compression coil spring which is adapted to generate lateral force between both ends along with the contraction of the vehicular suspension, a pitch angle of each winding is cyclically maximized or minimized along an elongating axial line.
