Abstract: The present disclosure relates to an indoor unit of an air conditioner, the indoor unit including: a case having an outlet elongated in one direction; a first vane disposed at the outlet; a second vane disposed at the outlet at a position behind the first vane; a drive motor disposed on one side of the outlet and configured to provide a driving force to at least one of the first vane or the second vane; a drive link coupled to a shaft of the drive motor, and having a first end connected to the first vane and a second end connected to the second vane; and a first vane link having a first end connected to the case and a second end connected to an end portion in a longitudinal direction of the first vane, wherein the first vane has a first curvature formed on a surface perpendicular to an air discharge direction and formed in the longitudinal direction, such that the outlet may be tightly closed in response to sagging of a central part of the first vane due to self-weight in a dual vane structure, and in response to torsion that occurs due to a third vane link provided in the dual vane structure.
