PROBLEM TO BE SOLVED: To provide a fitting mechanism of cartridge filter which enables the efficient attaching and removing with one operation in the attaching and removing operation of cartridge filter. SOLUTION: In the cartridge filter 1, a tube coupling 4 having downwardly- tapered outer surface is integrally fixed and disposed on the under part of an air hole 3 of a cell plate 2 which is horizontally fixed in a dust collector and a tube body 1B which is made of synthetic resin and is elastic is fixed on the upper end of a tubular filter 1A which is supported vertically-movably. Therein, the inner hole surface of the tube body 1B is constituted so as to be parallel with the outer surface inclination 1C of the tube coupling 4 and to be slightly smaller than the outer surface of the tube coupling 4.
