In the present invention, both a motor case (31) that has a stator (35) affixed to the inside thereof and a gear case (41) that contains a reduction mechanism (SD) are made from aluminum, making it possible to radiate, directly to the outside from the motor case (31), almost all of the heat produced by the stator (35) when this brushless wiper motor (20) is operating. That is, heat transmitted to the motor case (31) can be radiated to the outside more efficiently than in existing designs, making it so that the motor case (31) does not get that hot. This allows not only reductions in size, weight, and electrical noise, but also improvements in high-temperature strength, and manufacturing costs can be reduced due to the elimination of the need for high-cost components that can withstand high temperatures.
