An air conditioner includes a main body portion in which an air outlet is formed and a main body side mounting hole (24) is formed; a flap which changes a blowing direction of air; and a connecting member (21) which rotatably connects the flap with respect to the main body portion. The connecting member (21) has a mounting hole insertion portion (25) which is inserted into the main body side mounting hole (24). The mounting hole inserting portion (25) has an insertion main body portion (27) formed so that a total circumferential length of an outer circumferential surface is smaller than that of the main body side mounting hole (24), and an enlarged diameter portion (30) which is elastically deformable inward. The enlarged diameter portion (30) is formed so that a total circumferential length of the outer circumferential surface is larger than the circumferential length of the inner circumferential surface of the main body side mounting hole (24).
