Abstract
PURPOSE:To obtain a filter element which is sure in sealing properties and firm in the structure by forming the sealing part of an annular filter body which is supported on the upper and lower annular supporting bodies different in size into such a structure that the filter body and the supporting bodies are closely stuck. CONSTITUTION:A filter element 20 is constituted of a filter body 2, a supporting body 21, an upper sealing packing 22 and a lower sealing packing 23. The supporting body 21 has an upper supporting ring 26 provided with an annular groove 26a, a lower supporting ring 25 provided with an annular recessing part 25a opened downward in a turned guttering shape and a strut 24 radiately joining both. The filter body 2 is formed by radiately fluting and working a sheetlike filter medium. The upper sealing packing 22 is spread over the annular groove 26a and an upper end edge 15a and formed by urethane foam. The lower sealing packing 23 is spread over the lower supporting ring 25 and a lower end edge 16a of the filter body and formed into an annular shape by urethane foam.
