There are a plurality of axle boxes to accommodate a plurality of bearings supporting a pair of axles, a plate spring extending in a car longitudinal direction and supported by a pair of the axle boxes which are away from each other in the car longitudinal direction among the plurality of axle boxes. The plate spring supports the cross beam while being pressed by the corresponding support from above such that the pressing member is separable from the plate spring. Elastic walls are at both respective sides of the supports in the car longitudinal direction and sandwiched between a lower surface of the bogie frame and an upper surface of the plate spring so as to be compressed.
