PURPOSE: To lighten the calorific value by installing a plurality of rotor members, plurality of stator members, and a multidisc type disc brake device having the pressing members for acting a brake power on both the members, at the edge part of the rotor shaft of a driving electric motor which is connected in revolution transmission-enabled state with the axle of a railway rolling stock.

CONSTITUTION: A driving electric motor 2 is installed under the boggie of a railway rolling stock, and a driving gear fixed at one edge part of the rotor shaft 3 of the electric motor 2 and a driven gear fixed on an axle are meshed, and a disc brake device 1 is installed at the counter gear side edge part of the driving electric motor 2. The disc brake device 1 has two rotor members 10 installed on the outer periphery of a hollow shaft 9 joined with the rotor shaft 3 and three stator members 11 installed on the inner periphery of a key member 8 so as to be slided in the axial direction. A ring-shaped pressing plate 12 is arranged in proximity to the left side of the stator member 11, and a brake power is developed by pressing the pressing plate 12 by a plurality of pistons (pressing member) 15.
