PURPOSE: To nearly conform the geometrical axis of a coil spring to the axis of a damper rod in a fixed load range so as to reduce friction generated in a damper and improve riding comfortableness by arranging the geometrical axis of the coil spring slanting against the axis of the damper rod. CONSTITUTION: The geometrical axis Ls of a compression coil spring 9 is slanted against the axis Ld of the damper rod 8a of a damper 8 centering around the middle point O in the vertical direction of the coil spring 9. The slanting direction and the slanting quantity are set so that the loaded axis Lm of the coil spring 9 is nearly conformed to the axis Ld of the damper rod 8a in a fixed load range. When the load range is 100kg-600kg; namely in a normal load, the distance (l) between at least one axis Ls of both end faces of the coil spring 9 and the axis Ld of the damper rod is in the range of 10-25% of the coil radius S of the coil spring 9. |
