Abstract: In an electric motor cooling structure for cooling an electric motor provided in a power unit by jetting an oil to the electric motor, an oil passage for passing the oil therethrough is formed between a cover member covering the electric motor from outside and a lid member fitted to the cover member. The cover member is formed with a plurality of jet holes as through-holes communicating with the oil passage, and the plurality of jet holes are oriented in the same direction as an axial direction of the motor. The oil passage is formed in an annular shape as viewed in the axial direction of the electric motor. The cover member is formed with a second oil passage for supplying the oil to a rotary shaft of the electric motor. Such cooling structure efficiently cools the electric motor while suppressing processing cost with a simple oil passage structure.
