)項記載のクロスフローフアン。[Scope of Claim for Utility Model Registration] (1) A casing in a cross flow fan consisting of an electric motor, a multi-blade impeller integrally fixed to the rotating shaft of the electric motor, and a casing disposed to cover them. A support body, on which a motor is mounted at the tip thereof, is integrally formed inside approximately the center of the casing. A hole having a size slightly larger than the outer circumference of the multi-blade impeller whose one end surface is shielded is formed in the end wall surface in the axial direction of the multi-blade impeller, and the end surface of the multi-blade impeller is disposed in close proximity to the hole. A crossflow fan that is characterized by (2) The cross flow fan according to claim (1) of the utility model registration, characterized in that the rotating shaft of the electric motor and the fitting part of the multi-blade impeller have an asymmetric shape to prevent slippage. (3) Utility model registration claim No. 1 characterized in that the rotating shaft of the electric motor and the fitting part of the multi-blade impeller are fixedly pressed together through an elastic rubber member.
