Abstract
There is provided a suction device for a chain saw, comprising a suction chamber communicating with a suction port of a carburetor for an engine accommodated within the chain saw, and a muffling path formed within a rear handle of the chain saw to pass through said rear handle and provide communication between the suction chamber and atmosphere so that the suction noise of said engine is prevented from propagating outside due to the interference with the internal wall of said muffling path without providing separately for the chain saw a suction muffler or an air cleaner having a suction muffling path.
