摘要： A blowby gas processing device including a cylinder block, a cylinder head, a cylinder head cover, an oil separator and a flow velocity amplification device is provided. The cylinder block contains an inter-block passage constituting part of a blowby gas passage passing the blowby gas through in a crank case of an internal combustion engine and introducing the gas into an intake passage of the internal combustion engine. The cylinder head cover contains an in-head passage constituting part of the blowby gas passage provided in at least one of the cylinder head or the cylinder head cover. The oil separator is provided in the inter-block passage and configured to separate and remove oil from the blowby gas. The flow velocity amplification device increases the flow velocity of blowby gas flowing at a bottommost portion provided in the vicinity of the lowest position in the in-head passage.
