A first drain channel (25) is provided to the bottom wall surface (27) between the blow-by barrier (29) of a partition wall (20) and the blow-by-gas non-colliding part (33) of a collision plate (22). An oil introduction opening (36) in the first drain channel (25) opening to the bottom wall surface (27) is covered by the front-end surface (41) of a projecting wall (40) formed projecting on the back surface of a cylinder-head cover (1). The oil collecting in the first drain channel (25) in the oil separator (3) is thereby prevented from being carried up by the blow-by gas. |
