Abstract

A railcar bogie includes a plate spring supported by a pair of axle boxes arranged away from each other in a car longitudinal direction, the plate spring supporting a cross beam while being pressed by a pressing member of a bogie frame from above such that the pressing member is separable from the plate spring, at least a lower surface of the plate spring containing resin. The lower surface of the plate spring includes an inclined surface inclined with respect to a horizontal direction when viewed from a car width direction. The bogie frame includes at least one lifting supporting portion, the at least one lifting supporting portion including a supporting surface, the supporting surface being opposed to the inclined surface of the plate spring from below with a gap and inclined along the inclined surface of the plate spring.
