The gas-liquid separating chamber (70) includes: an inflow part (203) into which the blowby gas is introduced from the oil circulation pathway; oil discharge parts (204) configured to flow the oil separated from the blowby gas back to the oil circulation pathway; and a blowby gas discharge part (400) configured to discharge the blowby gas not containing oil mist from the gas-liquid separating chamber (70) and supplies the blowby gas to an intake passageway to a combustion chamber. The oil discharge parts (204) are formed as openings on at least two corners in a lower part of the gas-liquid separating chamber (70) in the longitudinal direction.",
