ABSTRACT:
A structure for supporting an air filter on a carburetor, the air filter having a casing accommodating an air filtration element and a cap adapted to close the upper opening of the casing, the cap being adapted to be centered and fixed to the carburetor by a cooperation of a center bolt projecting upward from the carburetor and a butterfly nut. The supporting structure has a supporting member adapted to be fixed to the carburetor, an annular disc-shaped first resilient member connected at its inner periphery to one end of the supporting member and at its outer periphery to the casing of the air filter, and a second resilient member through which the cap of the air filter is fixed to an opposite end of the supporting member. The vibration of the casing and the cap of the air filter is avoided thanks to the first and the second resilient members which insulate the casing and the cap from the vibration caused by the engine to which the air filter is attached.
