PROBLEM TO BE SOLVED: To provide a track gauge variable truck, capable of maintaining a function of track gauge conversion, arranging a derailment deviation prevention structure in a vehicle gauge, and suppressing increase of weight of the truck.SOLUTION: A track gauge variable truck comprises: a truck frame; an axle and a wheel; an axle box; an axle box beam; a slide stopper receiver; a lock device; a rub plate; and a bearing device. The axle box comprises therein a first bearing for rotatably supporting the axle. The lock device is fixed to the axle box beam and selectively locks a position of the slide stopper receiver in an axial direction. The bearing device is fixed to a lower part of the axle box beam, and disposed in a deviated state to outside of a vehicle width direction, with respect to a vehicle width direction center of the first bearing. The other end of the axle box beam has a first part disposed below the axle box, and a second part projecting downward from the first part so as to overlap to the bearing device in view from a vehicle longitudinal direction, and a notch is provided, the notch being opened to the wheel side by a lower face of the first part and an inside face of the second part.SELECTED DRAWING: Figure 4

    【課題】軌間可変台車において、軌間変換の機能を維持しつつ、脱線逸脱防止構造を車両限界内に配置し、更に台車の重量増加を抑制することを目的とする。【解決手段】軌間可変台車は、台車枠と、車軸と車輪と、軸箱と、軸箱梁と、スライドストッパ受と、ロック装置と、擦り板と、支承装置とを備える。軸箱は、車軸を回転自在に支持する第1軸受を内部に収容する。ロック装置は、軸箱梁に固定され、スライドストッパ受の軸線方向における位置を選択的にロックする。支承装置は軸箱梁の下部に固定され、第1軸受の車幅方向中心に対して車幅方向外側に偏って配置される。軸箱梁の他端部は、軸箱の下方に配置された第1部分と、車両長手方向から見て支承装置と重なるように第1部分から下方に突出する第2部分とを有し、第1部分の下面及び第2部分の内側面により車輪側に向けて開放された切欠き部が形成されている。【選択図】図4
