<p>PROBLEM TO BE SOLVED: To provide a Sirocco fan in which a size in a width direction in parallel with a rotating shaft of a fan rotor is easily reduced and an air blowing amount is easily assured.SOLUTION: A fan rotor 25 is formed with a right side rotor suction port 71 and a left side rotor suction port 72 for sucking air from each of a right side fan suction port 21 and a left side fan suction port 22 of a scroll casing 24 of a Sirocco fan 20. An outer-rotor type motor 26 is arranged at a deeper side in an internal space S1 of a fan rotor 25 rather than a first plane PL1 including the right side rotor suction port 71 and a second plane PL2 including the left side rotor suction port 72. The outer rotor type motor 26 has a motor stator 40 fixed not to be moved in respect with the scroll casing 24 and a magnet rotor 50 fixed to the fan rotor 25, and the magnet rotor 50 rotates around the motor stator 40.</p> |
