PROBLEM TO BE SOLVED: To cool the electronic parts for current application of a brushless motor, and besides, downsize the general constitution, and also, reduce the manufacturing cost, though it is of such constitution that it uses a brushless motor. SOLUTION: A blower 25 is equipped with a brushless motor 36 which is provided with an erected base 43 at the inner bottom of a housing 41 and is provided with a stator 46 at the outer periphery of this base 43, and is provided with a wiring board 48 where electronic parts 47 for controlling the current application to the stator 45 of this stator 46 and the rotary shaft 52 of an outer rotor 51 rotating outside the stator 46 is supported rotatably inside the base 43, a pipe 62 which supplies the base end of the base 43 within a housing 41 with a part of the wind produced by the fan 37 rotated by this fan motor 36, and, at the peripheral wall of the base 43, a ventilation 64 which is provided to pierce it from the base end to the tip and besides to connect with the pipe 62. |
