的に形成されている。2. Description of the Related Art Conventionally, there are various types of air filters used in air cleaners, and the typical types are shown in FIGS. 3 and 4. That is, a long filter paper 1 is folded in a zigzag shape at predetermined intervals to form a large number of pleats 2, and the filter paper 1 with the pleats 2 formed is rolled into a cylindrical shape to form the filter body 3. A cylindrical inner cylinder 5 having a large number of through holes 4 is attached to the inner peripheral part of the filter body 3.
An end plate 6 that covers both the upper and lower ends of the filter body 3 is integrally formed at both upper and lower ends of the filter body 3 .

It passes through the filter paper 1 and reaches the inner peripheral side of the filter body 3, and further reaches into the inner cylinder 5 through the first through hole 4. Then, when the air passes through the filter paper 1, dust and the like contained in the air are removed, and the air from which the dust and the like have been removed flows out from the openings 8.

より略ドーナツ形の濾体１１が形成されている。Embodiment An embodiment of the present invention will be explained based on FIGS. 1 and 2. First, a long filter paper 9 is bent in a zigzag shape at equal intervals to form a large number of elongated filter papers 10. next,
The pleats 1 on one side along the longitudinal direction of the filter paper 9
By widening the interval between the folds 10 and narrowing the interval between the pleats 10 on the other side along the longitudinal direction of the filter paper 9, and bonding both ends of the filter paper 9 together in the longitudinal direction, a substantially donut-shaped filter body 11 is formed. is formed.
なお、この濾体１１の幅寸法は前記ひだ１０の幅寸法と
略等しく設定されている。そして、略円形をなす前記濾
体１１の外周部にはリング状の支持部材１２が気密状態

１の内周部には封止体である樹脂１３が気密状態に充填
されている。Note that the width dimension of this filter body 11 is set to be approximately equal to the width dimension of the pleats 10. A ring-shaped support member 12 is airtightly fixed to the outer periphery of the substantially circular filter body 11. In addition, the filter body 1 is a substantially circular space.
The inner periphery of 1 is filled with resin 13, which is a sealing body, in an airtight state.

ーナ本体（図示せず）内に空気の流れる向きとびだ１０
とが直交する向きに取付けられている。なお、支持部材
１２はエアクリーナ本体の内周面部にバッキング等を介
して支持されている。The filter body 11, which has a support member 12 fixed to its outer circumference and whose inner circumference is filled with resin 13, has an extension 10 in the direction in which air flows within the air cleaner main body (not shown).
It is installed in the direction perpendicular to the Note that the support member 12 is supported on the inner peripheral surface of the air cleaner main body via a backing or the like.
このような構成において、エアクリーナ本体内に流入し

塵等を含んだ空気の洩れが防止される。In such a configuration, the air containing dust and the like flowing into the air cleaner body collides with the folds 10 of the filter body 11 in a state substantially perpendicular to the folds 10, and when passing through the filter paper 9, the dust and the like are filtered out. Note that the outer circumference and inner circumference of the filter body 11 are kept airtight by the support member 12 and the resin 13, respectively.
Air leakage containing dust, etc. is prevented.
ここで、濾体１１の外径寸法はエアクリーナ本体の内径
寸法と略等しく設定され、濾体１１はエアクリーナ本体
の内径の略全体を占めている。このため、エアクリーナ
本体の外径寸法を大型化することなく十分な濾過面積が
確保され、小型でかつ濾過性能に優れた濾過装置が得ら
れる。また。Here, the outer diameter of the filter body 11 is set to be approximately equal to the inner diameter of the air cleaner body, and the filter body 11 occupies approximately the entire inner diameter of the air cleaner body. Therefore, a sufficient filtration area is ensured without increasing the outer diameter of the air cleaner main body, and a filtration device that is small and has excellent filtration performance can be obtained. Also.
濾体１１の幅寸法はひだ１０の幅寸法と略等しく設定さ
れて非常に薄型化されており、このため、エアクリーナ
本体の高さ寸法を縮小することによる濾過装置の小型化
も達成される。The width dimension of the filter body 11 is set to be approximately equal to the width dimension of the pleats 10, making it extremely thin, and therefore, the filtration device can be made smaller by reducing the height dimension of the air cleaner body.
なお、本実施例においては濾体１１の幅寸法を薄型化し
