Claims

[Claims for Utility Model Registration] 1. A breather hole 2 is formed in the middle of the breather board 1 in the vertical and horizontal directions in an inclined or standing position, and the upper edge 3a of the oil-proof plate 3 having a convex longitudinal section is connected to the breather board. Breather hole 2 on the inner surface of 1
It is closely fixed to the upper surface portion 1a, and its lower edge 3b is in contact with the surface portion 1b lower than the breather hole 2, so that air can be conducted between the breather board 1 and the oil-proof plate 3. The channel 4 is formed to flow into the boolean hole 2 from the left and right,
This breather device for engine blow-by gas is characterized in that an inlet 5 of an air guide path 4 is formed by both left and right open ends 6 of an oil-proof plate 3 at a position left and right away from a breather hole 2.
-2 Utility model registration claims Paragraph 1
- A device in which an oil return hole 7 is provided below the breather hole 2 on the inner surface of the breather board 1 and above the lower edge 3b of the oil-proof plate 3.
