PURPOSE:To send air to every position in a passager's compartment, even a position far from a blow port, by operating a control member to set guide walls such that the latter substantially crosses the direction of stream of air in an air duct to throttle air introduced through an inflow port into a narrow width. CONSTITUTION:By operating a control member 10 to set guide wall elements 5a, 5a to substantially cross the direction of stream of air, air charged through an inflow port 2 is converged toward its center section and narrowed by the elements 5a, 5a so that the air has a high flow rate and is blown off from a blow port 3 in the form of a narrow strong air stream, thereby the air may reach a position far distance from the blow port 3. |
