Provided is a rail vehicle comprising a traction device which can absorb the vibration of a bogie in the front rear direction and which can improve the ride quality of the vehicle. A rail vehicle comprises a bogie (12) which supports the vehicle so that the vehicle can travel, a center pin (18) which is provided under the floor of the vehicle body (11), and a traction device which connects the center pin (18) and the bogie frame (70) of the bogie (12). The traction device comprises a rigid member (53) which is fitted over the center pin (18), and an elastic member (52) which is disposed on the inner surface of the bogie frame (70) so as to face the rigid member (53) in the front-rear direction (100) of the vehicle. The facing surface of the rigid member (53), which faces the elastic member (52), is sloped. As the acceleration or the deceleration of the vehicle increases, the area of contact between the facing surface and the elastic member (52) increases, and this increases the modulus of elasticity of the elastic member (52). |
