Abstract

PURPOSE: To easily regulate the size and to improve the executability by mounting a horizontal cover coating a branch tube via a stretchable vertical cover and stretchable in the extended horizontal direction of the tube at the lower end of a vertical cover. CONSTITUTION: A branching device comprises a vertical cover 40 which is hung from a frame 31 and vertically extended, and a horizontal cover 60 mounted at the lower side end of the cover 40 and extended in the horizontal direction. The cover 40 is divided into a fixed cover 41 and a movable cover 42 and longitudinally slidably engaged to be stretchable. The cover 60 is similarly divided into a fixed cover 61 and a movable cover 62, and longitudinally slidably engaged to be stretchable. Thus, since the branch cover is vertically and laterally stretchable, the size of the branch cover can be variably corresponded to the installing height of a tube cover 30 of an arbitrary site and a distance from the installation position to an outdoor unit.
