<P>PROBLEM TO BE SOLVED: To prevent an element of an air cleaner device from being fouled by oil included in blow-by gas, and to prevent film surface vibration of a casing of the air cleaner device. <P>SOLUTION: Air introduced from an air introducing port 21i of the casing 23 is derived from an air deriving port 22g by being mixed with the blow-by gas after filtering dust by passing through the element 24. Since a first side surface 22b in the vicinity of a blow-by gas introducing port 22f and a second side surface 22c in the vicinity of the air deriving port are connected by an oil guiding member 32, reduction in filtering performance when the oil sticks to the element, can be prevented by guiding the oil of coagulating oil mist included in the blow-by gas to the air deriving port along the oil guiding member. Moreover, since the oil guiding member connects the mutually opposed first and second side surfaces of the casing 23, generation of the film surface vibration is prevented by enhancing rigidity of the first and second side surfaces, to thereby contribute to reduction in intake noise. <P>COPYRIGHT: (C)2013,JPO&INPIT |
