Abstract (en)
An air intake duct (22, 30) and an air inlet pipe (12a) of an air cleaner (12) are combined to form an elongate conduit system through which ambient air to be fed to the combustion engine flows. A branch tube (24, 32) having a length half that of the elongeate conduit system is branched from the longitudinally intermediate portion of the system and closed at its leading end (24b, 32b). A viscous damping material (26), such as, a foamed polyurethane, a glass wool or the like is packed in the branch tube.
