Abstract
A bearing holder () having a bearing () rotatably supporting a crankshaft () is fixed so as to face an opening () of the engine case (). A gas-liquid separation chamber () is formed between a cover member () covering the opening () and the bearing holder (). Therefore, by utilizing the bearing holder () as a part of the wall surface of the gas-liquid separation chamber (), the gas-liquid separation chamber () can be partitioned without increasing the number of components and without forming a special wall surface in the engine case (). Thus, it is possible to reduce the size and weight of the engine case (), and reduce the cost by simplifying the shape thereof and reducing the number of components. Also, a labyrinthis formed by ribs () projecting from the bearing holder () and the cover member (), and therefore gas-liquid separation can be effectively performed by the labyrinth (). Thus, it is possible to provide a small light gas-liquid separation device with a small number of components.
