Abstract
A lubrication device for an engine, includes: an oil pan which is disposed at a lower portion of an engine and stores lubrication oil; an oil pump which is disposed above the oil pan and driven by the engine; a suction oil passage which guides the oil in the oil pan to a suction port of the oil pump; and a supply oil passage which guides the oil discharged from a discharge port of the oil pump to lubrication parts of the engine. The suction oil passage is divided into an upstream oil passage on a side of the oil pan and a downstream oil passage on a side of the oil pump. A filter net serving as a strainer is sandwiched between the upstream oil passage and the downstream oil passage. Thus, it is possible to provide the light and simply-structured lubrication device for an engine.
