When a blow-by gas collides with an outer circumferential wall of a tubular member 34, part of oil mist in the collision gas is liquefied (an oil droplet 38). The oil droplet 38 takes in the oil mist in the blow-by gas which flows into an intake pipe 16 in succession, and moves on the outer circumferential wall of the tubular member 34 in accordance with a flow of an intake gas and the gravity while keeping a liquefied state. The oil droplet 38 flows in from an inlet section 28 while keeping the liquefied state, and uniformly flows into a surface of an impeller 22 to be discharged to a scroll 30 side. A surface of a diffuser 32 is washed uniformly by the oil droplet 38 keeping the liquefied state, and generation or accumulation of the deposit on the surface can be restrained. |
