To provide a vehicle power transmission device which inhibits leakage of electromagnetic noise.SOLUTION: A vehicle power voltage device has: a motor; a power transmission mechanism which transmits power of the motor to traveling wheels; an electric power conversion system 400 which supplies alternating-current power to the motor; and a metallic housing 401 which houses the electric power conversion system. The housing includes: a box part 402 formed with a recessed part 405 which houses the electric power conversion system; a lid part 403 which closes an opening of the recessed part; bolts 404 which connect the lid part to the box part; and protrusion parts 420, each of which extends from the lid part to the box part and is connected to the box part at its tip. The box part 402 is electrically connected with a vehicle body.SELECTED DRAWING: Figure 4
