<P>PROBLEM TO BE SOLVED: To provide a motor unit for vehicles, which can effectively suppress the temperature rise of a coil in a simple structure. Ž<P>SOLUTION: The motor unit 10 for vehicles includes: a stator 21, in which a lead wire 17 is wound within a slot; a tubular rotor 22, which is arranged at an inner circumferential side of the stator; a housing, which stores the stator and the rotor; a shaft 24, which pierces the rotor axially; bearings 26 and 27, which support the shaft rotatably, being provided in the housing; and a lubricant feeder, which feeds the bearings with lubricant. In the unit, the axial end of the rotor is provided with a guide 50, which leads the lubricant to the projection 18 of a lead wire formed at the axial end of the stator.
