Claims

[Claims for Utility Model Registration] A lid 3 is detachably attached to the open end 2 of the air cleaner body 1, and a stepped portion 9 having a seating surface 8 facing toward the open end 2 is formed on the inner circumferential surface 7 of the main body 1, The collar 5a of the filter paper element 5 is seated on this seating surface 8 via a gasket 4 made of an elastically deformable material, and the filter paper element 5 divides the inside of the main body 1 into an outside air communication chamber 10 and a clean air chamber 11. A clean air outlet 13 is deviated and opened in the rear end wall 12 of 11, and an oil blowback blocking plate 6 is provided between the clean air outlet 13 and the filter paper element 5 in the clean air chamber 11. The step portion 9
A positioning groove 15 is formed by running from the seating surface 8 toward the rear end wall 12 side, and the oil blowback blocking plate 6
In the engine air cleaner constructed by engaging the positioning protrusion 16 with the positioning groove 15, the gasket 4 made of an elastically deformable material has its outer peripheral surface formed into a protrusion, and the protrusion 4a is connected to the stepped portion of the main body 1. 9. An air cleaner for an engine, characterized in that the engine air cleaner is configured to press against an inner circumferential surface portion 7a on the open end 2 side of the step portion 9 to form a gap 19 for generating an intermediate differential pressure at the inner corner of the stepped portion 9.
