ABSTRACT:
A grille for air conditioning for the instrument panel of an automobile is provided which includes a main case having an opening for blowing out a wind and a plurality of curvable wind direction adjusting plates supported so as to be rotatable relative to the main case. A support member supports the distal edges of the wind direction adjusting plates. The support member has extension plates respectively extending along an extending plane of the distal edge of each wind direction adjusting plate and coupling plates coupling the extension plates with each other. Each extension plate has a groove for receiving the distal edge which is not rotatable against the extension plate. The support member is movable on a circular locus relative to the main case, the arc having a shorter radius of curvature than a span between the two edges of the wind direction adjusting plate in an unstressed configuration.
