However, there is a drawback in that the filter body that is in close contact with the part is not effectively used as a filter surface. In the above conventional one, in the filter element in which a space is formed between the filter body and the coarse filter medium, since the filter medium and the coarse filter medium are not in contact with each other,
Although the above-mentioned drawbacks do not occur, the following other drawbacks are brought about. That is, the coarse filter medium is increased in size by the distance from the filter body, and when the filter element is mounted in the casing, the interval between the coarse filter medium and the casing inner wall is narrowed, and the flow path resistance is reduced. Will increase.

間から導入され、所定の濾過流量を確保する。The air flows in through the inlet of the upper case 12, a part of the air enters between the folds 11 from the outer periphery of the filter body 1, and the rest is the filter body 1.
Through the coarse filter material 2 on the upper surface of the above, enters between the pleats 11, flows through the inside of the filter body 1, and flows out toward the outlet of the lower case 13. During this time, dust in the air is filtered. The air may contain coarse leaves and the like, which may flow from the upper case 12. In that case, the upper surface of the coarse filter medium 2 will be covered, leading to a clogged state, but the air will have pleats 11, 11 on the outer periphery of the filter body 1.
Introduced from between to ensure a predetermined filtration flow rate.
