PURPOSE:To make it possible to realize the state of dispersion while utilizing the features of the conventional deflecting device and to uniformly air-condition the entire part of a room to be air-conditioned by varying the angle of a dispersing element with respect to the axis of a flowpath of the dispersing element in accordance with the shift of a bias shielding member. CONSTITUTION:In a case where a bias shielding member 13 is substantially hermetically connected to a nozzle 10, the flow of a dispersing element is deflected toward the right-hand direction. Upon this occasion, the dispersing element 16 shifts to the downstream simultaneously with a bias shielding member through an external shaft 15 whereby the dispersing element 16 comes into contact with a first engaging member 22 and rotates around a dispersing element shaft 17. The flow of air flowing through the nozzle 10 and deflected to the right-hand is more promoted to adhere to a guide wall because the dispersing element 16 is directed toward the direction in which the air flow is deflected, and hence the deflection characteristic of the element 16 is improved. By controlling the rotation of a motor 17a, the setting of the external shaft 15, that is, the positions and angles of the bias shielding member 13 and dispersing element 16 can be controlled. When the bias shielding member 13 is shifted to the most upstream side, the rotational angle alpha becomes approximately 90 deg., that is, a so-called dispersive condition is created. |
