<P>PROBLEM TO BE SOLVED: To prevent an element of an air cleaner device from being soiled by oil included in blow-by gas, to prevent film surface vibration of a casing of the air cleaner device, and to prevent oil component of blow-by gas led into a blow-by gas introduction port from freezing. <P>SOLUTION: Attachment of oil to an element 24 can be prevented by connecting the vicinity of a blow-by gas introduction port 22f and the vicinity of the air delivery port 22g are connected by an oil guide member 32 and by guiding oil contained in the blow-by gas to an air delivery port 22g with an oil guide member 32. When the blow-by gas is introduced into the casing 23 through a blow-by gas introduction port 22f at a low temperature, an oil guide member 32 facing the blow-by gas introduction port 22f covers a part connected to a first side surface 22b with bulkheads 22h, 22p, 22q. Low temperature air is blocked by the bulkheads 22h, 22p, 22q to be hardly contacted to the blow-by gas introduction port 22f. As a result, freezing of oil component of blow-by gas can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
