ABSTRACT:
Disclosed is a silencing filter for use in a power-driven machine arranged such that the air allowed to flow-in through an air intake port provided in a machine cover is caused to flow upwards by being caused to flow from lower ends of holes formed in extended portions of a filter element to upper ends thereof, thus being carried to a space area located above the filter element; and then the air is caused to flow downwards through the filter element and then, by being passed through the inside of machine frame portions, is guided up to an air inlet port of an internal combustion engine.
