Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a truck for a railway vehicle capable of preventing, with a simple construction, decrease of wheel load by effectively coping with torsion in planarity.SOLUTION: A truck for a railway vehicle comprises a truck frame 100 for a railway vehicle, to which a left side beam 120a and a right side beam 120b arranged in a longitudinal of a rail 50, and a transverse beam 110 arranged in a sleeper direction, are coupled. In the truck frame 100 for a railway vehicle, at least one part of the transverse beam 110 is cut, and the cut part is connected with both of an upper connection member 150a and a lower connection member 150b. Thereby, torsion in the whole transverse beam is adjusted to allow a truck to follow torsion in planarity more easily.SELECTED DRAWING: Figure 1 【課題】簡素な構成で平面性捻れに対応し車輪の輪重抜け防止が可能な鉄道車両用台車の提供。【解決手段】レール５０の前後方向に配置された左側側梁１２０ａ及び右側側梁１２０ｂと、枕木方向に配置された横梁１１０が接合された鉄道車両用台車枠１００を備える鉄道車両用台車枠１００において、横梁１１０は、少なくとも１カ所が切断され、該切断部分は上側接続部材１５０ａと下側接続部材１５０ｂとで接続される。この結果、横梁全体の捻れ剛性を調節し、台車が平面性捻れに追従し易くなる。【選択図】図１
