  "textContent": "A knee-action-type suspension (11) is provided with an arm member (20), a compression coil spring (21), and a shock absorber (24). The arm member (20) is supported in such a way that it is pivotable in the upward and downward directions by a pivot (31) provided on an arm mounting portion (30). The coil spring (21) is arranged between spring seats (22, 23). The coil spring (21) is extended and retracted between a full-rebound state and a full-bump state in accordance with the magnitude of a load applied to a vehicle body. A wire (40) of the coil spring (21) includes a large-diameter wire portion (40a), a small-diameter wire portion (40b), and a wire diameter varying portion (40c). The large-diameter wire portion (40a) is provided in a first portion (21a) of the coil spring (21), which is on the side near to the pivot (31). The small-diameter wire portion (40b) is provided in a second portion (21b) of the coil spring (21), which is on the side far from the pivot (31). A wire diameter (d1) of the large-diameter wire portion (40a) is greater than a wire diameter (d2) of the small-diameter wire portion (40b).",
