To provide a railway vehicle truck whose anti-rolling device has improved durability.SOLUTION: AS a torsion bar 22 is coupled with an arm 47 where a pair of wedge shaped tapered surfaces 27, 27 of an end 23 of the torsion bar 22 is received by a pair of corresponding wedge shaped tapered surfaces 49, 49 of square socket 48 of an arm 47, so a relative displacement between a fitted part 26 of the torsion bar 22 and the square socket 48 of the arm 47 is suppressed, wearing of coupling parts of the torsion bar 22 and the arm 47 is prevented and durability of an anti-rolling device 21 is improved.SELECTED DRAWING: Figure 5

    【課題】アンチローリング装置の耐久性を向上させた鉄道車両用台車を提供する。【解決手段】トーションバー22の端部23の楔形をなす一対のテーパ面27,27を、アーム47の四角穴48の、対応する楔形をなす一対のテーパ面49,49で受けることにより、トーションバー22とアーム47とを結合させたので、トーションバー22の嵌合部26とアーム47の四角穴48との相対変位が抑止され、トーションバー22とアーム47との結合部の摩耗を防ぐことが可能であり、アンチローリング装置21の耐久性を向上させることができる。【選択図】図5
