<p>Provided is a gas-liquid separation structure which prevents an oil component that has been separated from blow-by gas from being carried away by the blow-by gas. This structure is equipped with: a gas-liquid separation chamber (26), which is capable of removing the oil component from blow-by gas containing an oil component, and hanging walls (31, 32), which are provided hanging from the ceiling surface of the gas-liquid separation chamber (26), so as to be capable of preventing the oil component that has been separated from the blow-by gas and has adhered to the ceiling surface of the gas-liquid separation chamber (26) at least from flowing along the ceiling surface to the downstream side of the gas-liquid separation chamber. The lower end of the hanging walls (31, 32) is formed as an upward-protruding curve or a bend, so as to be capable of guiding the oil component such that the oil component drips down from a position that is away from the main current of the blow-by gas when the oil component drips down from the ceiling surface along the hanging walls (31, 32).</p> |
