    Abstract: PROBLEM TO BE SOLVED: To support two membrane-like members in the neighborhood of a through hole without fixing the membrane-like members to a core plate by providing two torus-like plates, each of which has a curved recessed part and a connector on opposed inner faces which fit together annular members arranged around a through hole part connecting the membrane- like members naturally, through the membrane-like members. SOLUTION: Pressing membranes 2a, 2b opposted to a filter cloth are mutually connected monolithically near an untreated liquid hole 5. An intermediate ring 8 arranged around an untreated liquid hole 2d in each of the pressing membranes 2a, 2b is of a smaller outer diameter than an untreated liquid hole 1d in a core plate 1 and can be positioned inside the untreated hole 1d. A pair of clamping plates 3a, 3b is formed of a tours-like plate member with an untreated hole 34 respectively. The intermediate ring 8 which sets the clamping plates 3a, 3b with a setescrew 6 though the pressing membranes 2a, 2b is arranged on both front/back faces of the membranes 2a, 2b inside the peripheral part of an untreated liquid hole 2d opened in the membranes 2a, 2b. Further, a the untreated liquid hole 24 part of the pressing membranes 2a, 2b is arranged in the untreated liquid hole 1d of the core plate 1 with an untreated liquid hole check tool 3. Thus is possible to protect both pressing membranes 2a, 2b and core plate 1 against concurrent damage to be inflected to the membranes 2a, 2b and the core plate 1 due to a pressure generated between these parts.
