Abstract An air-conditioning grille comprises an inner case having an opening through which the wind blows out located in a wind blowing duct. In the duct, provided are plural wind deflecting plates which are bendable so as to make both the ends thereof extend substantially crossing the blowing direction. In the duct provided is a connecting member which connects the upstream ends of the wind deflecting plates together and restricts rotations of these connecting portions relative to each other. Also provided is an operation member to be operated to bend the wind deflecting plates. One transfer shaft is provided to transfer an operational force of the operation member, at the time of its operation, to the connecting member. In order to prevent the connecting member from rotating itself about the transfer shaft with operation of the operation member, rotation moments of the connecting member about the transfer shaft substantially cancel one another.
An air-conditioning grille comprising: an air-duct casing for passing air therethrough, said air duct casing having upstream and downstream ends; an odd number greater than 1 of identical wind deflecting plates each having upstream and downstream ends, said downstream end of each of said deflecting plates being supported by said air duct casing; a connecting member disposed within said air duct casing for connecting said upstream ends of said deflecting plates together; moving means rotatably coupled to said air duct casing, said moving means being operably coupled to said deflecting plate so that said deflecting plates are bent in response to movements of said moving means, said moving means having a rotating axis located on a rotating axis of said downstream end of said deflecting plate that is located centrally in said plurality of deflecting plates; and a single transfer shaft for coupling said connecting member to said moving means, said deflecting plates being disposed symmetrically about said transfer shaft; wherein rotation moments about said transfer shaft that are generated by said deflecting plates substantially cancel one another; and wherein a notch is formed on said centrally located deflecting plate with one side of said moving means being disposed in said notch and the other side of said moving means protrudes outwardly from said air duct casing.
