Abstract

An engine for a vehicle can include an oil pan coupled to a lower portion of a crankcase, and a partition wall configured to partition a crank chamber in the crankcase and the oil pan. The partition wall can be disposed on the crankcase, and can include openings configured to return oil from a crank chamber side to an oil pan side. Bridges are configured to suppress back flow of the oil from the oil pan side to the crank chamber side. The bridges can be fixedly disposed below the openings so as to cover at least part of the openings from below.
