PROBLEM TO BE SOLVED: To provide a motor unit capable of improving efficiency of heat transfer from a motor to a motor case.SOLUTION: The motor unit comprises: a motor case 11 forming a motor chamber 14 in which a motor 20 is accommodated; a stator 23 that is supported by the motor case 11; and a rotor 22 which is disposed in an inner circumference of the stator 23 via an air gap and supported by the motor case 11 in a rotatable manner. At one end side of the rotor 22 in an axial direction, a blade 223 is provided that forms an air blow (arrow Win) toward a coil end 24e of the stator 23. Between the stator 23 and the motor case 11, an air blow passage 70 is provided that makes the air blow flow from a space 14a at a side where the blade 223 is provided, to a space 14b at an opposite side while interposing the stator 23 therebetween in a direction along the axial direction in the motor chamber 14.SELECTED DRAWING: Figure 1 |
