1. An air conditioner comprising:
an indoor unit that is mountable on a ceiling, the indoor unit including:
a panel having an air inlet in a central portion of the panel and an air outlet along a side of the panel;
a main flap that is rotatable about a first rotation shaft;
a sub-flap that is rotatable about a second rotation shaft;
a gear that is rotatable by a common motor, the gear including a first extended portion extending from the gear beyond an outer circumference of the gear in a first radial direction of the gear, and a second extended portion extending from the gear beyond the outer circumference of the gear in a second radial direction of the gear; and
a link engaged with the second extended portion and the sub-flap,
wherein
the main flap and the sub-flap are configured to guide air discharged from the air outlet in a direction determined by a position of the main flap and a position of the sub-flap, and
the main flap and the sub-flap have a state in which, via rotation of the gear by the common motor,
the main flap rotates about the first rotation shaft according to a force received by the main flap via the first extended portion, to change the position of the main flap, and
the sub-flap rotates about the second rotation shaft according to a force received by the sub-flap via the second extended portion and the link while the main flap is rotating about the first rotation shaft, to change the position of the sub-flap.
