ABSTRACT:
A duct with a damper is provided in an air conditioning apparatus to adjust an air flow rate. A slit is formed in the duct to be opened in a side wall. The damper comprises an opening and closing part inserted in the duct through the slit and a pivotal shaft which is turnably held by the duct. This construction facilitates easy connection of the damper to the duct. The damper undergoes opening and closing movement by a cable. The cable is fixed to a given position in the air conditioning apparatus by forming an engaging part at an end portion of the cable and by forming another engaging part in a cable supporting part for supporting cable at a position corresponding to the first engaging part so as to engage the two engaging parts.
