To provide a railway vehicle simplifying the structure of a vehicle body by dispersing transmission of load between a sub-frame 2 and the vehicle body 1 and capable of suppressing manufacturing cost in the railway vehicle using the sub-frame applied between a truck and a base frame and installed with a connector.
The truck 6 supports the sub-frame 2 through support rubbers 5, 5 and supports the vehicle body 1 through an air spring 3 above the support rubbers. The connector 10 is installed on the sub-frame 2. The neighborhood to the installation part supports the vehicle body through a support rubber 4. Rail direction load applied to the sub-frame 2 and tie direction load are shared by stopper rubbers 12, 13 and shock-absorption rubbers 8c, 8c installed between the air spring 3, the support rubber 4, left and right ends of the sub-frame and the base frame. Since a central pin is not used for connection of the sub-frame 2 and the vehicle body 1, the structure of the vehicle body 1 is simplified and enhancement of mounting accuracy and mounting workability are improved.
