Provided is a drive mechanism for a movable member of an air conditioner, the drive mechanism achieving downsizing of a motor while maintaining the same swing width of a vertical wind direction adjustment blade as in the prior art. In a drive unit (70), in a rack and pinion mechanism which converts a rotational motion into a reciprocating linear motion, an oscillating motion can be extracted directly from a rack (55) and a pinion (53) by causing the rack to draw a curved trajectory, thereby making it possible to omit a conventional member for converting the linear motion of the rack into an oscillating motion. Further, the amount of swing of a blade piece (201) of a vertical wind direction adjustment blade (20) can be adjusted by the amount of rotation of the pinion (53), and consequently the torque of a motor can be made smaller than in a conventional configuration in which the amount of swing is adjusted by the distance "from a motor shaft to a connection point between a first link and a second link". |
