A bogie frame for railway vehicles includes a pair of left and right side frames disposed along a direction of rails and a cross frame that connects the side frames to each other, and the cross frame includes a top plate member, a bottom plate member, and a pair of front and rear side plate members that are disposed between these plate members and welded thereto, wherein the cross frame has mounting bracket support portions that extend from front and rear edges of the top plate member and the bottom plate member, correspondingly to locations where mounting brackets for mounting a traction motor and mounting brackets for mounting a gearbox are disposed, and the mounting brackets are welded to the mounting bracket support portions. This makes it possible to achieve good welding workability for assembling the bogie frame.
