Zusammenfassung:	Provided is a drive mechanism for a movable member of an air conditioner, in which a motor can be reduced in size while keeping the same swinging width as per the prior art for a vertical airflow direction adjustment vane. In this drive unit (70), in a rack and pinion mechanism for converting rotational motion to reciprocating linear motion, swinging motion is extracted directly from a rack (55) and a pinion (53) by making the rack travel in a curved path, making it possible to omit the conventional member for converting the linear motion of the rack to swinging motion. Because the swinging amount of a vane piece (201) of a vertical airflow direction adjustment vane (20) can be adjusted according to the rotating amount of the pinion (53), the motor torque can be reduced to a greater extent than with a configuration in which the swinging amount is adjusted according to the distance "from the motor shaft to the linking point of the first link and the second link," as per conventional practice.
