PROBLEM TO BE SOLVED: To provide an oil separator structure for an engine increasing oil collecting performance by making oil collected by a plurality of beads not easily flow into a downstream side chamber, surely be collected in an upstream side chamber and easily discharged to an oil circulation system from an oil outlet, and facilitating flow of oil collected on a surface of the plurality of beads. SOLUTION: An oil separator chamber of an oil separator structure is partitioned by two partition wall into two upstream side chambers and a downstream side chamber between these upstream side chambers. The plurality of projecting beads oriented in a direction crossing a direction of main gas flow are formed in parallel on an inner surface of a ceiling wall of the upstream side chamber. In order to lead liquid oil residing at a lower end part of the bead to both side wall sides by gas flow, the beads are formed in roughly chevron shape moving to gas flow downstream side as they approach both side wall sides.
