A power transmission device for a vehicle is comprised of a motor including a rotor shaft and a stator having an electromagnetic coil; an inverter configured to generate an alternating current, the inverter being connected with the coil to controllably rotate the rotor shaft relative to the stator; a gear set including an input shaft coupled with and rotated by the rotor shaft, an output shaft and gears so meshed as to transmit torque of the input shaft to the output shaft; and a grounding path electrically connecting a part of the gear set with a body of the vehicle, the part being so disposed as to have the input shaft electrically interposed between the part and the rotor shaft.

A friction engagement element has a friction member including resin, and a metal member having a sliding surface slidable on the friction member. The friction member has an aged layer at an outermost layer of the friction member, and a hardened layer in abutment with an inner side of the aged layer in a thickness direction of the friction member. The sliding surface of the metal member has a plurality of recesses, and a transferred film of the aged layer of the friction member transferred and adhered to insides of the plurality of recesses through sliding between the friction member and the metal member.
