ABSTRACT:
A four-cycle engine is provided which is suitable for use in a vehicle or an apparatus such as a small jet boat to be operated on the premise that it often overturns, and which is simple in structure. An oil pan 22 is disposed below the bottom of a crankcase 13, the spaces in the components are communicated with each other via a communicating hole 27 which is formed in the bottom of the crankcase 13, and a cylindrical peripheral wall 26 which is downwardly extending from the bottom of the crankcase 13 toward the oil pan 22 is formed around the communicating hole 27 and is spacially separated from the side wall of the oil pan 22 by a distance.
