Abstract

PURPOSE:To enable a predetermined uniform flow to be attained even if a variation occurs in a flow of air at an upstream side caused by a variation of a fan or the like by a method wherein an air amount distribution control vane arranged at an upstreams side of an outlet is provided with an opening or closing device to be opened or closed in response to a pressure difference between a front surface and a rear surface. CONSTITUTION:An air direction distributing control vane 3 is arranged near an outlet 6, and an air amount distributing control vane 2 is arranged at an upstream side. The air amount distribution control vane 2 is provided with an opening or closing device 4 to be opened or closed in response to a pressure of it. The opening or closing device 4 to be opened or closed in response to the pressure is comprised of two vanes 8 and 10 pivotally mounted by a rotary shaft 9 within an opening 11 formed in the air amount distribution control vane 2. The vane 10 is positioned at a location where the opening 11 is normally closed. The vane 8 is arranged at the front and rear surfaces of the air amount distributing control vane 2 so as to be projected in perpendicular to the surfaces and further positioned substantially at a right angled position against an air stream 11 flowing along the air amount distribution control vane 2.
