AIR DISCHARGE DEVICE

PURPOSE:To make it possible to easily load a plurality of louvers by mounting louver support frame body supporting front louvers and rear louvers within the housing. CONSTITUTION:Respective front louvers 4 are mounted between both left and right front louvers support frames 10 of a louver support body 6, and respective rear louvers 5 are mounted on both vertical rear support frames 11. Upon this occasion, the intervals between both front lour support frames 10 and both rear louver support frames 11 can be widened elastically. Respective shaft holes 17 and 19 of links 16 and 18 are fitted in connecting shafts 4b and 5b of louver 4 and 5, and respective louvers 4 and 5 are connected to each other so as to integrally rotate the louvers 4 and 5 in linkage therewith. The louver support frame member 6 is inserted into the housing 3, and respective engaging projections 15 on the upper and lower surfaces of the louvers support frame body 6 are engaged with engaging grooves 9 on upper and lower inner surfaces of the housing 3, and the louver support frame body 6 is held within the housing 3. By these procedures, a plurality of louvers can be easily loaded within the housing.
