Document Type and Number:
Japanese Patent JP7022171
Kind Code:
B2
Abstract:
To provide a filter structure which can be adjusted for sizes of various objects.SOLUTION: A filter structure 1 comprises a regular square-shaped filter body 2, and an adhesive part 3. The adhesive part 3 is formed in such a manner that an adhesive is coated on one face of the filter body 2. Further, the adhesive part 3 is formed into a belt-like form having a constant width, and includes a first lattice part 31, a second lattice part 32, a third lattice part 33 and a fourth lattice part 34 which have a lattice shape . The first lattice part 31 is located in a first region R1, and is coated in a lattice shape of 3×3 with a position of less than a constant width from an outer periphery of the first region R1 as an outer edge, whereby nine sections are formed. Widths of nine sections are so set as to be gradually larger in the order of a center side, an outer side and the middle. The second lattice part is formed symmetrically to the first lattice part with respect to a second line. The third lattice part and the fourth lattice part are formed symmetrically to the first lattice part and the second lattice part respectively with respect to a first line.SELECTED DRAWING: Figure 1
