A vertical shaft head is provided in which the oil that is introduced into the head cover chamber 1 and flows out to the breather device 2, separated from the blow-by gas and accumulated in the head cover chamber 1, is returned to the oil pan 5 through an oil return passage 6 led out from the head cover chamber 1. In a valve engine blow-by gas mixed oil return device, the outlet 6a of the oil return path 6 is connected to the oil pan 5.
The vertical shaft overhead valve engine is characterized in that the separated oil in the head cover chamber 1 is directly returned from the oil return passage 6 to below the surface of the lubricating oil stored in the oil pan 5. A return device for oil mixed with blow-by gas.
