Abstract
The first opening part penetrates the first partition wall that separates the crank chamber and the oil sump chamber. The lubricating device of the engine includes an oil mist generation control part. The oil mist generation control part disperses gas injected from the crank chamber into the oil sump chamber through the first opening part when the crank chamber has a positive pressure or restricts the flow of oil with which the injected gas collides, thereby controlling an amount of oil mist generated in the oil sump chamber.
