Abstract
In producing a blow-out port device in a two-stage inject:on molding process by use of synthetic resin, the blow-out port device having a housing including pairs of shaft bores and pairs of circular section bosses both provided in and on opposed wall portion of a peripheral wall of the housing, and a plurality of blades each including a pair of protruding portions provided at opposite ends of each of blade bodies disposed within the housing to abut against a pair of boss and to have the same outside diameter as the boss, and a pair of support shafts projectingly provided on end faces of the protruding portions and turnably fitted in the shaft bores, the housing is forced at a primary injection step, and then, the blades are formed at a secondary injection step by use of the shaft bores in the housing as support shaft-forming cavities. Thus, it is possible to provide an air-conditioning blow-out port device having an improved appearance around a mounting portion of each blade.
