PURPOSE:To make it possible to easily adjust the air flow direction, to simplify the housing configuration and to reduce the number of assembly process steps by holding a sheet assembly between a fixed grill and a back retainer and inserting through guide slits of first and second sheets. CONSTITUTION:An airstream guide member 3 is comprised of a sheet assembly having a plurality of laterally long holes 13a disposed in accordance with intervals of lateral beams of a fixed grill 9 at the upper and lower parts, a laterally long guide slit 13b at its control portion, and second sheets 15 alternately stacked on each other. In this assembly, laterally long holes 13a and longitudinally long holes 15a intersect each other to form an airstream guide A, and operating pins 7b of the operating member 7 are inserted through guide slits 13b and 15b of first and second sheets 13 and 15 and the rear retainer 5.
