ABSTRACT:
In an working machine in which: an engine and a fuel tank for the engine are mounted on a machine body; an air cleaner mounted outside the machine body has a cleaner case including a cylindrical case body and a lid body being mounted on one end of the case body, and a cleaner element being housed in the cleaner case and dividing the inside of the cleaner case into a pre-purification chamber and a post-purification chamber; and an air-outlet pipe is connected to an intake system of the engine with an intake duct interposed therebetween, a canister capable of absorbing a vaporized fuel generated in the fuel tank is attached to the fuel tank or the machine body; a purge joint communicating with the post-purification chamber is provided to the lid body of the air cleaner; and a purge conduit extending from the canister is connected to the purge joint. Accordingly, it is possible to take a vaporized fuel generated in the fuel tank into the engine by utilizing the lid body of the air cleaner.
