SHUTTER DRIVING DEVICE OF INDOOR UNIT OF PACKAGE TYPE AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide a shutter driving device of an indoor unit of a package type air conditioner. SOLUTION: The shutter driving device has a lifter 30 for moving a shutter 10 upward/downward while moving upward/downward with the working force of a driving motor 40 transmitted via a driving roller 45, and a plurality of guide rollers 65 are disposed between the lifter 30 and a lifting guide 55 for guiding the upward/downward movement of the lifter 30. Accordingly, the surface contact between the lifter 30 and the lifting guide 55 is changed to the line contact, so that the frictional force and the noise caused thereby are reduced and the driving torque can be reduced.
