A bogie frame for railway vehicles includes: a pair of left and right side beams disposed along a direction of rails; a cross beam that connects the side beams to each other; and a mounting bracket for mounting a functional part, the mounting bracket being joined to the cross beam, wherein the cross beam has a rectangular cross section and includes a top plate section, a bottom plate section, and a pair of side plate sections; the top plate section has a cutout opening extending to one of the side plate sections; the mounting bracket is inserted in the cutout opening; and the mounting bracket and the top plate section are joined together by butt welding. This configuration enhances welding workability for welding mounting brackets for mounting functional parts such as a traction motor, a gearbox, and a brake, and allows a greater degree of design flexibility for the positions where functional parts are mounted.
