Abstract
An air conditioner includes: an air passage extending from a suction port to a blowout port, a heat exchanger at the upstream side of the air passage, a cross flow fan in the air passage on the downstream side of the heat exchanger, and an air passage wall provided in a downstream area of the cross flow fan to reach the blowout port. A restricting section that restricts an air passage sectional area is provided at a corner section of the side wall of the air passage wall. The restricting section has a shape by which the air passage sectional area has a rectangular cross section expanding from the upstream side to the downstream side and is restricted to reduce an enlargement ratio of the air passage sectional area. Further, the restricting section has a smooth restricting surface crossing the corner section of the cross section of the air passage.
