Abstract
A sub-gallery for leading oil to a cylinder head side of an engine is provided in a crankcase in such a manner as to be connected to an outlet of an oil filter and in parallel with a main gallery. A lubricating device is also provided to equally feed oil to each of portions to be lubricated in the engine, including the main gallery connected to a discharge port of an oil pump via the oil filter. This lubricating device sufficiently feeds oil to even the cylinder head side of the engine while avoiding increased pressure loss of the oil.
