PROBLEM TO BE SOLVED: To realize a plurality of vehicle body support methods by one truck.SOLUTION: A truck for a railway vehicle comprises: wheel shafts; truck frames supporting the wheel shafts; bolsters turnable with respect to the truck frames; pneumatic springs intervening between the truck frames and the bolsters; a traction device transmitting the traction force from the truck frame to a vehicle body; and a bolster regulation device which can switch from a first state where the turning resistance of the bolster with respect to the vehicle body is imparted to a second state where the turning resistance of the bolster with respect to the vehicle body is smaller than that in the first state.SELECTED DRAWING: Figure 1
【課題】1つの台車で複数の車体支持方式を実現可能にする。【解決手段】鉄道車両用台車は、輪軸と、前記輪軸を支持する台車枠と、前記台車枠に対して旋回可能なボルスタと、前記台車枠と前記ボルスタとの間に介在する空気バネと、前記台車枠から車体に牽引力を伝達する牽引装置と、前記車体に対する前記ボルスタの旋回抵抗を付与する第1状態と、前記車体に対する前記ボルスタの旋回抵抗を前記第1状態よりも小さくする第2状態との間で切換動作可能なボルスタ規制装置と、を備える。【選択図】図1
