Abstract
A brake disc for a railway vehicle, including a ring-shaped plate portion with a front side serving as a frictional surface and a plurality of fins being projected and disposed radially on the back side of the plate portion, the plate portion being fixed to a wheel, wherein a rib is provided between fins adjacent to each other, and a slit developing in the direction from a wheel-side face of the rib toward the back side of the plate portion is disposed in a circumferentially intermediate portion of the rib, thereby making it possible to suppress the deformation caused by frictional heat.
