To provide a cartridge type filter that reduces necessary force in inserting a filtration cartridge into a fixed cap to connect and withdrawing the same from the fixed cap.
An inclined trough 14 and an inclined protruded piece 33 which are interlocked with each other are installed to the fixed cap 10 and the filtration cartridge 20. Thus, the filtration cartridge 20 is proceeded axially and both the filtration cartridge and the fixed cap can be inserted and connected with each other by rotating the filtration cartridge 20 against the fixed cap 10. In withdrawing the filtration cartridge 20, it is rotated reversely when connected. Thus, the necessary force in the case of insertion and connection and in the case of withdrawal is largely reduced as compared to the necessary force in the conventional case of directly pushing axially or withdrawing the filtration cartridge 20. Therefore, the load added to the piping and the like at the working is also reduced.
