Abstract

This invention inhibits the turbulence of airflow of conditioned air that is blown out from a blowout part and improves the energy efficiency of air conditioning when branching the conditioned air by a mounting structure part of a motor for driving a flap. An air conditioner having: a casing including a suction opening for sucking in indoor air and a blowout part for blowing out conditioned air; and a blower and a heat exchanger housed inside the casing has a flap 303 which is mounted on the blowout part and which adjusts the blowing direction of the conditioned air, and a motor 50 which serves as a drive source for oscillating the flap 303 and is provided at a position which avoids lengthwise ends of the blowout part. The motor 50 is provided with a flow-adjusting cover 80 formed in a shape of branching the conditioned air toward the respective lengthwise ends of the blowout part.
