To provide a truck for a railway vehicle and a railway vehicle capable of improving ride quality of the railway vehicle and maintaining a vehicle body at an appropriate angle when the railway vehicle passes through a curve section.SOLUTION: A truck 10 for a railway vehicle includes a truck frame 12 and a pair of pneumatic springs 18. The truck frame 12 has a pair of auxiliary air chambers 24 provided corresponding to each of the pair of pneumatic springs 18 and a pair of valve devices 46 provided corresponding to each of the pair of auxiliary air chambers 24. Each auxiliary air chamber 24 includes a first air chamber 40 communicating with the pneumatic spring 18 and a second air chamber 42 communicating with the first air chamber 40 through a connection part 45. The valve device 46 brings the connection part 45 into an opened state when the pneumatic pressure inside the pneumatic spring 18 and the first air chamber 40 is a predetermined value or less and brings the connection part 45 into a closed state when the pneumatic pressure exceeds the predetermined value.SELECTED DRAWING: Figure 2

    【課題】鉄道車両の乗り心地を良くするとともに、鉄道車両が曲線区間を通過する際に車体を適切な角度に維持することができる鉄道車両用台車および鉄道車両を提供する。【解決手段】鉄道車両用台車10は、台車枠12と一対の空気ばね18とを備える。台車枠12は、一対の空気ばね18にそれぞれ対応して設けられる一対の補助空気室24と、一対の補助空気室24にそれぞれ対応して設けられる一対の弁装置46を有する。各補助空気室24は、空気ばね18に連通する第1空気室40と、接続部45を介して第1空気室40に連通する第2空気室42とを含む。弁装置46は、空気ばね18および第1空気室40内の空気圧が所定の値以下の場合に接続部45を開状態にし、上記空気圧が上記所定の値を超えることにより接続部45を閉状態にする。【選択図】 図2
