PURPOSE:To smoothly perform regeneration operation, by providing the filter discs fixed to and supported by a support shaft and a cleaner blade supported by said shaft in a loosely engaged state and contacted with the specific position of a stopper. CONSTITUTION:The liquid to be filtered introduced into a container 3 through an introducing port 1 passes through the gaps formed between opposed filter disks 9 to flow in a filter cartridge 6 and subsequently discharged out of the container 3 as a filtrate from a lead-out port 2. When a solid is adhered to the outer periphery of the cartridge 6, a support shaft 8 is rotated. Whereupon, as against that the discs 9 continuously rotate in a state fixed to and supported by a support shaft 8, cleaner blades 10 are contacted with a stopper 13 and the resolution thereof is stopped while the scraping action due to the blades 10 begins with the stoppage of revolution and the above-mentioned adhered solid is scraped off. At this time, because two mutually opposed blades 10 stop at mutually shifted positions, the solid is easy to fall and the accumulation thereof on each blade 10 is prevented.
