ABSTRACT:
A running gear for an electric rolling stock has coupling devices for coupling the output shafts of traction motors to the input shafts of reduction devices which are provided with electrically resistive elements so as to prevent return current from flowing therethrough. Therefore, the coupling devices possess a higher level of resistance than the grounding resistance of the grounding devices, thereby enabling any return current to be prevented from flowing through the coupling devices. Thus, the running device can be kept free from electrolytic corrosion.
