Abstract

A differential mechanism is provided between first output shaft, to which the rotation of the drive motor is transmitted, and second output shaft, to which the rotation of first output shaft is transmitted, for adjusting the relative positions of these two output shafts. An air-mix door is connected to first output shaft, and a blowout mode door is connected to second output shaft. The rotation of the drive motor is used to operate the air-mix door and the blowout mode door in linkage, and the blowout mode door is designed to be able to be independently operated by the operation of movable lever of differential gear mechanism.
