PROBLEM TO BE SOLVED: To make buckling of a piston rod difficult by improving maintainability without increasing man hours during installation on a railway vehicle.SOLUTION: A vehicle body support device 11 is constructed such that a vehicle body 6 is supported by a front truck 4a and a rear truck 4b. Cylinder devices 12a and 12b each arranged on the same sides in a vehicle width direction, to which piston rods 12aa and 12ba are attached via universal joints 13a, are connected to a vehicle body 6 positioned above both sides of both trucks in the vehicle width direction via piping 14. Rod-like members 15a and 15b are arranged in the vehicle width direction, and supported on both trucks so as to be rotatable around an axis. Arms 16a and 16b are integrally attached to both ends of the rod-like members 15a and 15b. The ends of the cylinders 12ab and 12bb of the cylinder devices 12a and 12b on opposite piston rod sides and the tips of the arms 16a and 16b are connected to each other via the universal joints 13b.SELECTED DRAWING: Figure 1

    【課題】鉄道車両に設置する際の作業工数を増加させず、メンテナンス性を改善し、ピストンロッドを座屈し難くする。【解決手段】前台車4aと後台車4bによって車体6を支持する車体支持装置11である。両台車の車両幅方向両側の上方に位置する車体6に、自在継手13aを介してピストンロッド12aa,12baを取り付けたシリンダ装置12a,12bの、車両幅方向の同じ側に配置されたシリンダ装置12a,12bを配管14で繋ぐ。棒状部材15a,15bを車両幅方向に配置し、軸中心周りの回転自在に両台車に支持させる。棒状部材15a,15bの両端部にアーム16a,16bを一体的に取り付ける。シリンダ装置12a,12bのシリンダ12ab,12bbの反ピストンロッド側の端部とアーム16a,16bの先端部を、それぞれ自在継手13bを介して連結する。【選択図】図1
