摘要： An air-conditioning blow-out port unit comprises a housing formed by a primary injection molding of synthetic resin and having a plurality of coaxially arranged shaft holes provided in opposed sidewalls, and a plurality of blades formed in the housing by a secondary injection molding of synthetic resin and each having a pair of support shafts projectingly provided at the opposite sides of a blade body and turnably fitted in each pair of the shaft holes. In this air-conditioning blow-out port unit, an extra shaft portion is consecutively formed on the support shaft to project outwardly from the housing with the same diameter as the support shaft, and a flange is formed between the support shaft and the blade body in an opposed relation to an inner surface of the housing. With this unit, a turning feeling of the blade can be stablized irrespective of thermal expansion and shrinkage of the housing and the blade.
