To provide an air conditioner in which an air deflection plate having a relatively large mass and size is rotatable with a relatively small sized driving motor.

The present air conditioner is adapted such that a driving apparatus for driving an air deflection plate 6 includes a driving motor 8 having a driving shaft 8a, a first link 9 including a base end coupled with the driving shaft 8a and a first coupling part a provided on a tip end thereof, a second link 10 including a base end part coupled with the support shaft 7 of the air deflection part, including a second coupling part b provided on a tip end thereof, and having a long size with respect to the first link 9, and a rod 11 coupled with the first and the second coupling parts a and b at opposite ends thereof.
