PROBLEM TO BE SOLVED: To provide a bogie for a railroad vehicle capable of reducing production manhours, by promoting weight reduction, by reducing stress of a welding part of brake device installation receivers and cross beams, in the bogie for the railroad vehicle. SOLUTION: This bogie for the railroad vehicle includes a bogie frame 5a composed of side beams 10 and 10 separately arranged in parallel and the cross breams 20 and 20 penetrating through a central part in the longitudinal direction of the side beams 10 and 10, two wheel sets having a wheel 240 in both end parts of a wheel shaft 230, a brake device 56 and an air spring 210. By providing an air spring receiving base 50 in the form of penetrating both end parts of the cross beams 20 and 20 through the central part in its longitudinal direction, the stress caused by the moment acting on the brake device installation receivers 54a and 54a can be reduced when a brake acts. Since the air spring receiving base 50 and the brake device installation receivers 54a and 54a are integrally constituted, manhours required for manufacturing a part and manhours for installing the part in the bogie frame, can be reduced.
