Abstract
A drive mechanism is configured to drive a movable member of an air conditioner. The drive mechanism includes a motor, a pinion secured to a rotating shaft of the motor, a rack meshing with the pinion, and a guide. The rack has a driven portion directly or indirectly linked to the movable member. The guide is arranged to guide the rack so that the driven portion can travel in a curved path. The guide has a tube part through which the rack passes.

A drive mechanism configured to drive a movable member of an air conditioner, the drive mechanism comprising:
- a motor;
- a pinion secured to a rotating shaft of the motor;
- a rack having a driven portion directly or indirectly linked to the movable member, the rack meshing with the pinion, the driven potion having an elongated shape;
- and
- a guide arranged to guide the rack so that the driven portion can travel in a curved path,
- the guide having a tube part through which the rack passes along a longitudinal direction of the driven potion, and
- the rack having a protuberance that protrudes from a portion accommodated in the tube part toward an inner surface of the tube part.
