ABSTRACT:
An air cleaner for an engine of a snow mobile provided with an endless vehicle track driven by the engine, includes an air cleaner main body comprising a duct extending longitudinally of the snow mobile and disposed on a floor covering of the endless vehicle track. The air cleaner main body is connected at its forward end to a carburetor for the engine and includes a rearward portion formed with a plurality of air inlet apertures. A riders' seat is mounted on the rear portion of the air cleaner main body and includes a shock-absorbing member for enclosing the air inlet apertures and an outer cover member for covering the shock-absorbing member. The shock-absorbing member serves concurrently as a cleaning element of the air cleaner, and at least one air intake port is formed in the outer cover of the seat at its rear end or one or both of its sides. The air cleaner main body is formed with an increased volume section which serves as a muffler for silencing engine intake noises.
