PROBLEM TO BE SOLVED: To stabilize a vehicle body attitude in a collision, while simplifying a vehicle body structure and also reducing weight.SOLUTION: A vehicle body of a railway vehicle comprises an underframe, a first member supported by the underframe in a state of being arranged on one side in the vertical direction more than the center in the vertical direction of the underframe and absorbing collision energy and a second member supported by the underframe in a state of being arranged on the other side in the vertical direction more than the center in the vertical direction of the underframe and contacting with an obstacle when the first member is compressed by a collision with the obstacle, and when the first member is compressed by the collision with the obstacle, the second member receives reaction from the obstacle, so that the second member transmits a moment load of inverse rotation of a moment load transmitted to the underframe to the underframe by the first member.SELECTED DRAWING: Figure 1 |
