PROBLEM TO BE SOLVED: To prevent occurrence of position deviation of a liner while improving the attachment/detachment workability of the liner included between the axle box and spring of a truck for railway vehicle.SOLUTION: A wheel load adjuster comprises at least a liner included between an axle box and a spring supported directly or indirectly to the axle box. The liner is equipped with: a pressure receiving part for receiving a load from the spring; a first engaging part engaging with a first engaged part which hollows inward from a part of the outer edge of the pressure receiving part and protrudes from the top face of the axle box, and regulating the displacement to the axle box; and a second engaging part which protrudes outside from the pressure receiving part in an opposite side of the first engaging part and engages with a second engaged part of the axle box to regulate the displacement and rotation to the axle box.SELECTED DRAWING: Figure 4
【課題】鉄道車両用台車の軸箱とバネとの間に介在させるライナーの着脱作業性を良好にしつつ、ライナーの位置ずれを防止する。【解決手段】軸箱と、前記軸箱に直接又は間接に支持されるバネとの間に介在させる少なくとも1つのライナーからなる輪重調整具であって、前記ライナーは、前記バネからの荷重を受ける受圧部と、前記受圧部の外縁の一部から内方に窪み、かつ、前記軸箱の上面から突出する第1被係合部と係合して前記軸箱に対する変位を規制する第1係合部と、前記第1係合部とは反対側において前記受圧部から外方に突出し、かつ、前記軸箱の第2被係合部と係合して前記軸箱に対する変位及び回転を規制する第2係合部と、を備える。【選択図】図4
