PURPOSE: An oil pan of an engine is provided to improve rigidity and to improve a vibration resistance about vibration from an engine or an external factor by forming a bead in a dip sump and a bottom surface and a side of an oil pan. CONSTITUTION: An oil pan of an engine comprises a connection peripheral part(110), a connecting part(112), a first, a second, a third, and a fourth sides(121,123), a bottom part(130), a deep sump(140), a device for oil pouring(150), and multiple beads(160). The connecting part is formed in the connection peripheral part with multiple, and is connected with a lower part of an engine by a connecting means. The first, the second, the third, and the fourth sides are formed at a side in every direction of an oil pan of a lower side of the connection peripheral part. The bottom part is formed at a lower side of a third side selected among the first, the second, the third, and the fourth sides. The dip sump is connected to one side of the bottom part, and is formed deeper than a surface of a bottom part into a down direction. The device for oil pouring is formed in one side selected among the first, the second, the third, and the fourth sides, and an engine oil pipe is connected. Multiple beads are formed with bending at more than one selected among the first, the second, the third, and the fourth sides, and the dip sump.
