Abstract: A drive apparatus includes: a motor having a shaft; a bearing rotatably supporting the shaft; a housing for the motor and holding the bearing in a bearing holding portion; an insulating member between the bearing and the bearing holding portion; and an oil passage. The bearing holding portion includes a holding tubular portion holding the bearing from radially outside, and a holding bottom portion extending radially inward from an end on one side in the axial direction of the holding tubular portion. The insulating member includes an insulating tubular portion extending in the axial direction along the holding tubular portion, and an insulating bottom portion extending in the radial direction along the holding bottom portion. The holding tubular portion has a penetrating portion penetrating radially inside and outside. The oil passage includes a first channel inside the penetrating portion and a second channel connecting the first channel and the bearing.

Abstract: A drive device includes a shaft, a rotor, a stator, a bearing, a housing, a first neutralizing device, and a seal member. The shaft extends in the axial direction along a rotation axis. The rotor is fixed to the shaft and is rotatable about the rotation axis. The stator faces the rotor with a gap therebetween in the radial direction. The bearing rotatably supports the shaft. The housing accommodates the rotor, the stator, and the bearing. The first neutralizing device is arranged on one axial side of the bearing and electrically connects the shaft and the housing. The seal member is arranged between the bearing and the first neutralizing device in the axial direction.
