PROBLEM TO BE SOLVED: To provide a vehicle body support device for a railway vehicle capable of preventing the deterioration in ride-comfort by securing lateral rigidity for supporting a vehicle body without imparting the lateral rigidity (rigidity in the different direction) to a bolster spring, and capable of reducing weight and cost by simplifying the bolster spring.SOLUTION: In a vehicle body support device 1 for a railway vehicle having a traction link 30 for connecting a center pin 40 joined to a vehicle body 5 and a truck frame 10 and a pair of left-right air springs 20 and 20 provided between the vehicle body 5 and the truck frame 10 and supporting the vehicle body 5, the traction link 30 is branched off in the horizontal direction on the side connected to the truck frame 10, and its branched-off respective end parts are respectively provided with rubber bushes 33a and 33b.SELECTED DRAWING: Figure 1

    【課題】枕バネに左右剛性(異方向剛性)を持たせることなく、車体支持の左右剛性を確保して乗り心地の悪化を防止するとともに、枕バネの簡素化を図って軽量化及び低コスト化を行うことができる鉄道車両用車体支持装置を提供すること。【解決手段】車体5に結合される中心ピン40と台車枠10とを連結する牽引リンク30と、車体5と台車枠10との間に設けられて車体5を支持する左右一対の空気バネ20,20とを有する鉄道車両用車体支持装置1において、牽引リンク30は、台車枠10に連結する側では水平方向へ分岐しており、その分岐した各端部にそれぞれゴムブッシュ33a,33bを備えている。【選択図】図1
