In a grounding structure for a driving unit of a motor-driven vehicle, the driving unit includes a dynamoelectric machine (4) that outputs driving power to the rotating axis (So) and a driving power transmission mechanism (5) including a rotating device (60) coupled to the rotating axis (So), the dynamoelectric machine (4) being connected to the driving power transmission mechanism (5). The grounding structure includes an coupling portion (41,42) provided to an machine casing (40) serving as an outer shell of the dynamoelectric machine (4) and being coupled to a mechanism casing (50) serving as an outer shell of the driving power transmission mechanism (5); a coupling portion (51,52) provided to the mechanism casing (50) and being coupled to the coupling portion (41,42) of the machine casing (40); a circumference wall (71) that forms a space (R) by arranging the coupling portion (41,42) of the machine casing (40) and the coupling portion (51,52) of the mechanism casing (50) so as to face each other between machine casing (40) and the mechanism casing (50); a casing hole (H C1 ) through which the space (R) communicates with an inside of the mechanism casing (50); a pressure release hole that releases a pressure of the space (R) by causing the space (R) to communicate with an outside of the mechanism casing (50); and a grounding object (8) that is disposed in the space (R) and that grounds the rotating device (60).
