<p>PROBLEM TO BE SOLVED: To provide a filter apparatus for fine particle in exhaust having a filter body fixed to an internal support without damaging an air permeable cylindrical body comprising a fiber aggregate. SOLUTION: In the filter apparatus, the internal support 3 is arranged in the air permeable cylindrical body 2 comprising the fiber aggregate and a U-shaped fastenings are pushed in both side surfaces of the finger part 3b thereof to assemble the filter body 1. Each of the fastenings 5 is constituted of two flat plate parts 5a positioned on both side surfaces of the finger part 3b of the internal support 3, an arcuate connection part 5b and the press parts 5c formed to the outer surfaces of the leading ends of the flat plate parts 5a. The outer surface of the connection part 5b is tightly bound by a tight bending member 7 to mutually press the press parts 5c to support the air permeable cylindrical body 2 on the internal support 3.</p> |
