Claims

[Claims for Utility Model Registration] A large number of rectangular filter papers that are continuous through folded twill lines are erected between two parallel end plates, and the space occupied by these filter papers has a hollow cylindrical shape as a whole. A filter element that has a filter paper arrangement pattern that satisfies the following configurations (a) to (e). (a)...A plurality of filter paper groups that are rotationally symmetrical with respect to the center line of the hollow cylinder constitute the same pattern. (b) ...The bent twill lines on the outer circumferential side of the filter paper group are arranged at substantially equal pitches almost along the outer circumferential circle. (c) In the above filter paper group, multiple pieces located on one side are
The bent twill line on the inner circumferential side is made up of approximately equal length parts arranged at approximately equal pitches along the inner circumferential circle, and a connecting part between filter paper groups located on the other side and connected to this equal length part. . (d) The connecting portions are arranged such that the inner circumferential folding curve is located along the starting end filter paper of the approximately equal length portion of the other filter paper group adjacent to the circumferential direction, and the connecting portions are sequentially shortened toward the outer circumferential circle. (e) At least one of the filter paper groups has a density different from that of the other filter paper groups.
