AIR-CONDITIONING DOOR AND INSTALLING METHOD FOR AIR-CONDITIONING DOOR

PROBLEM TO BE SOLVED: To arrange air-conditioning doors independently controlled in respective branch passage and to assemble the air-conditioning doors to an air-conditioning unit in a relatively short time regarding the air-conditioning unit in which a flow passage of air is divided into a plurality of branch passages. SOLUTION: Prior to installation, an air mix door 35 consists of a cylindrical body 40; a plurality of rotation shafts 36 positioned at both axial sides relative to the cylindrical body 40 and having a smaller outer diameter dimension than an inner diameter of the cylindrical body 40; a door body 37 radially extending from the rotation shaft 36; and a connection part 41 for connecting an opening end of the cylindrical body 40 and a cylindrical body side end of the rotation shaft 36. The connection part 41 can be broken by axial force of the rotation shaft 36. After the cylindrical body 40 of the air mix door 35 is clamped by two constitution member constituting a partition member 23, force is applied to the air mix door 35 toward an axial center of the rotation shaft 36. Thereby, the connection part 41 is broken and it is divided into the plurality of air mix doors 35, 35. COPYRIGHT: (C)2008,JPO&INPIT
