Abstract: An air conditioner includes: a stepped portion provided on a side of an outlet of an air passage wall; an air passage extension having a rotary shaft in the outlet, the air passage extension being rotatable in an opening direction about the rotary shaft to bring a rear end into abutment with the stepped portion in such a manner that the air passage extension integrates with the air passage wall to form a curved surface of a predetermined curvature; and a rotary mechanism configured to cause the air passage extension to rotate in such a manner as to bring the rear end into abutment with the stepped portion when the air conditioner is put into operation.

Abstract: There is provided a front flap 6 having a rotary shaft 61 at a front side of an outlet 5 to be rotatable outwardly from a housing 2 about the rotary shaft 61; a rotary mechanism 62 that rotates the front flap 6; an auxiliary flap 8 coupled with the front flap 6 and disposed inside the housing 2, and having a rotary shaft 81 disposed on the same axial center as that of the rotary shaft 61 to be rotatable about the rotary shaft 81; and a rotary mechanism 82 that rotates the auxiliary flap 8.
