Abstract

PURPOSE: For facilitating the shake-down of dust attachment and ensuring standing long-time use, to feed a filter medium and to mold the closing members of a synthetic resin into the combined structures with the tops of said filter medium.
CONSTITUTION: An almost flat filter medium is provided with a number of long holes 11 and folded so that some of said long holes 11 may position at the tops of some folds and the almost medium portion of the other adjacent ones of said long holes 11 may position at the tops of the other folds. Closing members 12 are so molded into the combined structures with the peripheral portions of said long holes 11 of said filter medium 10 as to close said long holes 11. The inner and outer circumferential faces thereof are shaped in arc to constitute a filter A. Thus, the deep portions of the folds of this filter device is prevented from getting clogged with dust, the dust having attached to said filter A can be shaked off, and the damage of said filter can be prevented unlike conventional ones.
