PROBLEM TO BE SOLVED: To suppress wheel load fluctuation in the operated state of a stopper in an axle box suspension in which the axis of an elastic bush is directed in a vehicle longitudinal direction.SOLUTION: This axle box suspension for the railroad vehicle truck connects an axle box having a bearing housed therein to support an axle to a truck frame, and is provided with: an axis beam body part extending from the axle box in a vehicle longitudinal direction; an axis beam having a pin part projected from the tip of the axis beam body part in the vehicle longitudinal direction; a cylindrical elastic bush having an inner cylindrical part, an outer cylindrical part, and an elastic part provided between the inner cylindrical part and the outer cylindrical part, the inner cylindrical part being fitted to the pin part; an adapter that is attached to the outer cylindrical part and that connects the axis beam to the truck frame; and a first stopper that is attached to the pin part and that comes into contact with the adapter to restrict displacement when the axle box is displaced by a prescribed distance to one side in the vehicle longitudinal direction with respect to the truck frame.SELECTED DRAWING: Figure 3

    【課題】弾性ブッシュの軸線を車両長手方向に向けた軸箱支持装置において、ストッパが作用した状態での輪重変動を抑制する。【解決手段】車軸を支持する軸受が収容された軸箱を台車枠に連結する鉄道車両用台車の軸箱支持装置であって、前記軸箱から車両長手方向に延びる軸梁本体部と、前記軸梁本体部の先端から車両長手方向に突出するピン部とを有する軸梁と、内筒部と、外筒部と、前記内筒部と前記外筒部との間に介設された弾性部とを有し、前記内筒部が前記ピン部に嵌合される筒状の弾性ブッシュと、前記外筒部に取り付けられ、前記軸梁と台車枠とを連結するアダプタと、前記ピン部に取り付けられ、前記軸箱が前記台車枠に対して車両長手方向一方側に所定距離変位したときに前記アダプタに接触して変位を規制する第1ストッパと、を備える。【選択図】図3
