Abstract
Abstract An air intake duct is formed on an upper case of an air cleaner. The bottom surface of the air intake duct is also an upper surface of the upper case. An opening portion of the air intake duct is opened rearwardly of the vehicle, and a recessed portion is formed on the upper surface of the upper case at a portion in front of the opening portion of the air intake duct relative to the air flow direction in the air intake duct. As a result, the bottom surface of the opening portion is formed higher than the surface of the recessed portion. The bottom surface of the air intake duct is formed to be gradually upwardly inclined in the direction of the air flow in the air intake duct traveling from the opening portion of the air intake duct to an opening portion formed on the upper surface of the upper case.
