In a breather device for an internal combustion engine, the bottom of the lubricating oil separation chamber is communicated with a space on the end face of a suitable rotating shaft,
The rotary shaft is characterized by forming a forced oil passage that communicates with the space and opens into the crank chamber, and rotates with the rotation of the rotary shaft to forcibly feed the lubricating oil in the space into the crank chamber. Breather device for internal combustion engines. (2) Utility model registration claim 1, which is equipped with a centrifugal force-type forced oil feed passage that forms a passage from the center of the rotating shaft to the outer peripheral surface of the rotating shaft as the forced oil feed passage goes downstream. Breather device for internal combustion engines. (3) A breather device for an internal combustion engine according to claim 1, wherein a spiral groove is formed on the outer peripheral surface of the rotating shaft as a forced oil feeding passage. (4) As a forced oil passage, a forced oil passage outlet is provided on the outer circumferential surface of the rotating shaft, and a communication hole that opens into the crank chamber is provided in the boss of the rotating shaft, and the position of the communication hole is adjusted when the crank chamber is under negative pressure. A breather device for an internal combustion engine according to claim 1, wherein the breather device is formed in a position communicating with the forced passage outlet. (5) A breather device for an internal combustion engine according to any one of claims 2 to 4, which utilizes a camshaft as a rotating shaft. (6) A breather device for an internal combustion engine according to any one of claims 2 to 4, which utilizes a crankshaft as a rotating shaft.
