To compact a blower and to blow air in directions of both sides of a sirocco fan.

An electric motor 6 is constituted of a ring rotor 8 and a stator 10 to support the rotor 8 free to rotate. A plural number of magnets constituting the electric motor are arranged on an outer periphery of the rotor 8, an iron core is arranged on an inner periphery of the stator 10 and a coil is installed on each yoke of the iron core. When this coil of the electric motor 6 is properly electrified, the rotor 8 is rotated by interaction between the magnetized iron core of the stator and the magnets installed on the rotor 8. Consequently, blade bodies 18 are rotated, air flows in a direction shown with an arrow B and it is ventilated outside, for example, from a diffuser of an air conditioner. Additionally, as blade bodies 20 are simultaneously rotated at this time, air currents are generated in both side directions (direction of an arrow C) of a sirocco fan 4 from both side end parts of the sirocco fan 4.
