Description of the Related Art A conventional oil mist separator is, for example, as shown in FIG. 5, a blow-by gas inlet portion 1, a container portion 2 having a mechanism for capturing oil mist in blow-by gas therein, and a blow-by gas outlet portion 3. And an oil drain portion 4 for returning the trapped oil to the engine body.

As shown in FIG. 5 is known. (For example, Japanese Utility Model Application Laid-Open No. 63-105712) This mechanism bends the flow of the blow-by gas passing through the container portion 2 by the bypass plates 5a, 5b, 5c, ... The oil mist collides with and adheres to each of the bypass plates and is captured. The trapped oil falls on the bottom of the container and is finally returned to the engine body from the oil drain section 4.

となっていた。However, in such a conventional oil mist separator, the oil drain portion which collides with the surfaces of the detour plates 5a, 5b, 5c, ... Since it was configured to return to the engine body from 4, the oil once adhered is separated from the surface by the flow of the blowby gas and is blown away while falling on the bottom surface along the surface of the detour plates 5a, 5b, 5c. It is easy to be carried away to the downstream through the opening 7, and this has been a factor of lowering the capture efficiency.

効率を上げることが可能となる。According to the present invention, due to the shape of the bypass plate, the oil that once collides with and adheres to the surface of the bypass plate enters the groove shape when flowing on the surface of the bypass plate toward the opening due to the flow of blow-by gas. Therefore, the oil is smoothly dropped to the bottom of the container along the continuous groove shape toward the bottom of the container, so that the oil is effectively collected in the oil drain on the bottom. It can be returned to the engine body. Due to these effects, it becomes possible to increase the oil mist capturing efficiency.
