This vehicular air cleaner device (60) is provided with a connecting tube (110) which extends from an air cleaner (80) to an air intake passage of an internal combustion engine. The connecting tube (110) is provided with a connecting-tube flange part (111) which extends in the radial direction. In a case main body (81), a cylindrical part (85) is formed so as to surround the connecting tube (110). In the cylindrical part (85), a connecting opening (86) is formed towards the inside of the case main body (81). A gas-liquid separation chamber (120) has, connected thereto, a blow-by hose (62) for guiding a blow-by gas. The gas-liquid separation chamber (120) is formed by bringing the inner end (87) of the cylindrical part (85) into contact with a side surface of the connecting-tube flange part (111), to occlude the connecting opening (86) with the connecting-tube flange part (111), and bringing an outer end part (88) of the cylindrical part (85) into contact with the wall of the connecting tube (110). |
