The purpose of the present invention is to ensure reduction performance of radio noise while improving a workability and preventing a brush protective jig for protecting a brush contact from being forgotten to be removed, when assembling a sliding contact brush. A power transmission device for an electrically driven vehicle includes: a reduction gear mechanism (3); a sliding contact brush assembly (25); a brush case cover (16); and a protective cover (20). The reduction gear mechanism (3) is interposed between a motor (1) driven by an inverter (2) and drive wheels (9,9). The sliding contact brush assembly (25) is provided at the position of a shaft end (3c') of a countershaft (3c). The brush case cover (16) is mounted to a cover mounting portion (19). The protective cover (20) is mounted so as to cover brush contacts (5a, 5a) when the sliding contact brush assembly (25) is assembled to the shaft end (3c'). The protective cover (20) is set to have the axial length (L) interfering with the brush case cover (16), when the brush case cover (16) is mounted to the cover mounting portion (19) in a state where the protective cover (20) is installed.
