Abstract
An oil pan forms a bottom portion of a crankcase of an engine. A partition wall extends upwardly from a bottom surface of the oil pan. The partition wall partitions an inside of the oil pan into a first region in which engine oil is stored and a second region in which the engine oil is not stored. An opening of an air introduction passage is arranged in the second region. The air introduction passage guides air from an intake passage to the crankcase for ventilation.
