Abstract
An oil pan structure includes a plurality of reinforcement beads of several kinds. An engine utilizes the oil pan, whereby the strength and vibration-rigidity (rigidity against vibration) of the oil pan and the engine are sufficiently enhanced so that a natural frequency of the oil pan and the engine therewith becomes adjustable through a selection as to the numbers, locations, and sizes of the beads.
