PROBLEM TO BE SOLVED: To provide a truck capable of not only preventing wheel load omission, but also effectively reducing lateral pressure.SOLUTION: A truck 1 includes: a leaf spring 16 which extends in a vehicle longitudinal direction while being supported by a first shaft box 14 at one end portion and supported by a second shaft body 15 at the other end portion, and supports a pressing member 21 from a lower side so as to be able to relatively displace; a first upper link 22 and a first lower link 23 which connect a lateral beam 5 and the first shaft body 14, and are elastically coupled to the first shaft box 14 at respective one end portions; and a second upper link 24 and a second lower link 25 which connect the lateral beam 5 and the second shaft box 15, and are elastically coupled to the second shaft box 15 at respective one end portions. Coupling points of the one end portions of the first upper link 22 and the first lower link 23 and the first shaft box 14 are disposed on a first virtual straight line L1 passing through a center of a first axle 8 in a side view, and coupling points of the one end portions of the second upper link 24 and the second lower link 25 and the second shaft box 15 are disposed on a second virtual straight line L2 passing through a center of a second axle 9 in a side view.SELECTED DRAWING: Figure 1

    【課題】輪重抜け防止だけでなく横圧も効果的に低減できる台車を提供する。【解決手段】台車1は、一端部が第1軸箱14に支持され且つ他端部が第2軸箱15に支持された状態で車両長手方向に延び、押圧部材21に対して相対変位可能に下方から支持する板バネ16と、横梁5と第1軸箱14とを接続し、それぞれの一端部が第1軸箱14に弾性的に連結される第1上リンク22及び第1下リンク23と、横梁5と第2軸箱15とを接続し、それぞれの一端部が第2軸箱15に弾性的に連結される第2上リンク24及び第2下リンク25とを備え、第1上リンク22及び第1下リンク23の一端部と第1軸箱14との連結点は、側面視にて第1車軸8の中心を通る第1仮想直線L1上に配置され、第2上リンク24及び第2下リンク25の一端部と第2軸箱15との連結点は、側面視にて第2車軸9の中心を通る第2仮想直線L2上に配置される。【選択図】図1
