PURPOSE:To improve a blowoff effect with all the wind from a connecting duct blown off in the direction of a wind regulating vane, by setting up a neck part tightened inward behind the outer frame as well as a passage to be set apart rearward to the connecting duct of an air conditioner for automobiles, etc. CONSTITUTION:A connecting duct 10 whose tip 10a is set tight to the rear external of an outer frame 4 consists of a neck part 10b closed tight inward behind the outer frame 4, a passage 10c set apart profressively larger toward the rear and a cylinderlike passage 10b in addition. With this constitution, when wind regulation does not take place, wind nearby the inner surface of the connecting duct 10, as shown in a, the whole amount of wind from the duct 10 is blown off forward straight as it is along a wind regulating vane 1 at the outside. Next, when a wind regulating vane 2 is directed to a C direction, wind at the left is blown off intact in the C direction along the wind regulating vane 1 but at the right blown off in the c direction after it has once collided with the wind regulating vane 1; the whole amount of wind thus comes blown off in the C direction. |
