FIN SUPPORTING STRUCTURE OF BLOW-OUT OPENING FOR AIR-CONDITIONING

摘要

PROBLEM TO BE SOLVED: To provide a fin supporting structure of a blow-out opening for air conditioning capable of preventing rapid change of rotation load of a fin when the fin is rotated and obtaining excellent feeling of fin operation.;SOLUTION: A fin support member 4 is formed of olefin thermoplastic elastomer having Shore hardness of A80 and/or D60 by a die. The olefin thermoplastic elastomer has a characteristic that the transfer property of the die is inferior to that of other thermoplastic elastomers. If the fin support member 4 is formed of the olefin thermoplastic elastomer having such a characteristic, a large number of fine irregularities are formed on a surface of the molded fin support member 4 regardless of a processing status on a surface of the die. As a result of almost uniformly distributing a large number of fine irregularities on the surface of the fin support member 4 including a circumferential surface of a penetration hole 4b, rotation shafts of wind guide fins 7a-7d are supported by the circumferential surface of the penetration hole 4b, so to speak, in a state of point contact.;COPYRIGHT: (C)2009,JPO&INPIT
