Abstract: Provided is an indoor unit of an air conditioner, and the indoor unit includes: a case installed indoors and having an outlet formed in a front or bottom thereof; and a vane module disposed at the case and guiding a flow direction of air discharged from the outlet, and the vane module includes: a first vane disposed in the outlet and rotatably installed on a forward side of a discharge direction of discharged air; a second vane disposed in the outlet and rotatably installed; two motor coupling parts disposed at both ends of the first vane and the second vane, respectively, wherein two motors each have at least a portion of which is exposed to the outlet; a vane motor assembled with at least one of the two motor coupling parts and providing a driving force; a drive link assembled to be rotatable rotatably to the motor coupling part, rotated by the driving force of the vane motor, and transmitting the driving force to the first vane and the second vane; a first vane link assembled to be relatively rotatable with the drive link and the motor coupling part on a forward side of the drive link to thereby rotate the first vane; and a second vane link assembled to be relatively rotatable with the drive link and the motor coupling part on a forward side of the drive link to thereby rotate the second vane, and the first vane link and the second vane link are assembled in a line with the drive link on a forward side of the drive link. Accordingly, a size of the vane itself may be maximized by minimizing a space occupied by a drive module.
