PURPOSE: To impede generating a magnetic sound so as to reduce an operating noise, by arranging a toroidal coil blower fan motor formed by dividing a yoke to prevent a yoke divided surface from being opposed to an adjacent magnetic metal material. CONSTITUTION: A yoke 31 of a toroidal coil fan motor 22 is divided into two parts along a line La of connecting the center position of a lead wire 34 and a rotary shaft O, to form a coil part 32. The line La along this yoke divided surface is tilted by a prescribed angleθwith respect to a vertical center line La of a motor supporting plate 20 and a motor cover 21, to set up the fan motor 22. In this way, vibration of the motor cover 21 and the motor supporting plate 20 formed of magnetic metal material can be avoided regardless of changing a leakage flux amount, to obtain suppressing a magnetic sound, and comfortable air conditioning can be attained.
