摘要： A drive unit includes: a rotating electric machine having a rotation axis extending in a horizontal direction; a rotating electric machine case; and a power conversion device. The power conversion device is arranged on one side of the rotating electric machine in an orthogonal direction. The power conversion device includes a first connector to which a first electric power line through which electric power supplied to the rotating electric machine and electric power supplied from the rotating electric machine flow are connected. The first connector is provided on a first end side and is arranged to protrude from the power conversion device at a predetermined angle in a direction away from the rotating electric machine in the orthogonal direction, as the first connector goes away from the power conversion device in the rotation axis direction, when viewed from above.

摘要： A driving unit includes a rotary electric machine which has a rotation axis extending in a horizontal direction, a rotary electric machine case, and an electric power conversion device. The electric power conversion device has an electric power conversion device case and is disposed on one side of the rotary electric machine in an orthogonal direction. The electric power conversion device case is fixed to the rotary electric machine case. At either the electric power conversion device case or the rotary electric machine case, a guide portion protruding in the orthogonal direction and extending in the rotation axis direction is formed above a connecting portion where the rotary electric machine and the electric power conversion device are electrically connected.

摘要： A planetary gear mechanism has a sun gear disposed to a rotating shaft, a plurality of pinion gears, a carrier supporting the plurality of the pinion gears, a ring gear meshing with the pinion gear on the outer diameter side of the carrier and a case holding the ring gear on the outer diameter side thereof. The ring gear is slidable in the axial direction of the rotating shaft with respect to the case. The planetary gear mechanism has a load transmission member abutting to an inner diameter side end portion of the ring gear and holding the carrier and the ring gear so as to be relatively rotatable. The load transmission member transmits an axial load from the ring gear to the carrier.
