Abstract
A lubrication apparatus for a four-stroke engine includes an oil tank, a supply passageway having an opening to supply oil mist from the oil tank to driving parts, the opening being provided in the oil tank. A partition is provided between the opening and a side wall of the oil tank, the partition being formed by partition plate members so as to divide an inside of the oil tank into an inner area and an outer area. The inner area includes the opening, and the outer area is defined between the inner area and the side wall. Oil can freely move between the inner area and the outer area, and the opening is placed in a position above a surface of the oil accumulated in the oil tank even when the four-stroke engine is tilted in every direction.
