ABSTRACT:
An air cleaner of an internal combustion engine including an air inlet conduit connected to a main body containing a filter element and composed of upper and lower longitudinally extending conduit portions formed of a synthetic resin and connected together. The lower conduit portion is formed integrally with a heated air inlet port, and the upper conduit portion is formed integrally with a stepped flange for constituting a lower half portion of a housing of a vacuum motor. A cap is joined by supersonic melt adhesion or bonding to the stepped flange with an outer peripheral edge of a diaphragm being held therebetween, to provide an upper half portion of the housing of the vacuum motor. The diaphragm is connected at its upper portion to a valve body for opening and closing the heated air inlet port which is controlled by the vacuum motor of the diaphragm type.
