One embodiment of a motor unit according to the present invention is provided with an electric power generator including a first shaft which rotates by means of a motive force of an engine, a motor having a second shaft, a housing, oil which accumulates in a lower region of an accommodating portion, and a first pump portion which is positioned inside the accommodating portion and which is driven by means of the rotation of the first shaft. An oil passage includes a first oil passage. The first oil passage includes a first sucking-up oil passage connected from the lower region of the accommodating portion to the first pump portion, a first shaft inner oil passage which is connected to a discharge port of the first pump portion and extends inside the first shaft along a first axis of rotation, a first radial oil passage which extends from the first shaft inner oil passage to a radially outer side to supply oil to a first stator, and a motor supply oil passage which extends from the discharge port of the first pump portion toward the motor to supply oil to the motor.
