PURPOSE:To enable a precise diffusing of cooled air or heated air by stretching a coil spring made of form storing alloy and a biasing spring on a wind shifter which is fitted rotatably at a lower position within a diffuser frame and in a diffuser. CONSTITUTION:An air conditioning diffuser 12 consisting of a diffuser frame 16 through which a first automatic wind directing part 50a having a coil spring 60 made of form storing alloy and a biasing spring 62 is associated to right and left wind shifters 18 is provided in a ceiling surface (C). In the case that heated air or cooled air is diffused into a room by connecting a connection port 24 to an air conditioning duct, when the heated air having high temperature is diffused, the coil spring 60 made of form storing alloy contracts has a lower dead shaft 54b of a crank part 54 stopped by a stopper 56 because of extension elasticity of the biasing spring 62, whereby a pair of upper and lower openings 32a and 32b of an arched long plate of the right and left wind shifters 18 are set automatically into the vertical direction, and heated air is diffused from a diffuser 14 downward, that is, vertically with respect the ceiling surface (C). |
