構造。[Claims for Utility Model Registration] (1) A first separator chamber communicating with the crank chamber, a second separator chamber separated from the first separator chamber by a partition wall and communicating with the outside of the engine, and a second separator chamber communicating with the outside of the engine; In an oil separator structure having a siphon structure, the oil separator structure is provided with an oil reservoir and a siphon passage whose one end opens into the first separator chamber and whose other end opens into the oil reservoir. An oil separator structure for an engine, characterized in that a bypass passage forming means is provided for forming a bypass passage that bypasses an oil reservoir and communicates a first separator chamber and a second separator chamber during periods of time. (2) In the oil separator structure for an engine according to claim 1, the bypass passage forming means includes a bimetal that bulges toward the oil reservoir side as the temperature rises, and one end portion of which bulges out of the bimetal. 1. An oil separator structure for an engine, characterized in that it is formed of a pipe member that is displaced toward an oil reservoir side as the engine moves, and whose other end opens toward a first separator chamber.
