摘要：
A wheel load adjusting tool includes at least one liner interposed between an axle box and a spring directly or indirectly supported by the axle box, the liner including: a pressure receiving portion configured to receive a load applied from the spring; a first engaging portion formed by recessing a part of an outer edge of the pressure receiving portion inward, the first engaging portion engaging with a first engaged portion to restrict the liner from being displaced with respect to the axle box, the first engaged portion projecting from an upper surface of the axle box; and a second engaging portion projecting outward from the pressure receiving portion at an opposite side of the first engaging portion, the second engaging portion engaging with a second engaged portion of the axle box to restrict the liner from being displaced and rotated with respect to the axle box.
