PROBLEM TO BE SOLVED: To regulate pulsation, to absorb cold air, and to prevent penetration of water by a method wherein a cleaner cap and a cleaner case are combined together to form an air chamber and meanwhile, one side of the air chamber forms an air input port. SOLUTION: Air penetrates into an air chamber 31 through an air inlet 34 and after pulsation is regulated, the air flows in a dirty side 26 after the flow of it through an inlet pipe 33. Air in the dirty side 26 is purified by an air filter 29 and flows in the clean side 28 and is guided to a carburetor. By combining together a cleaner cap 23 and a cleaner case 24 in such a state to be divided into two sections of one being the front and the other being a rear, an air chamber 31 is formed at the front part thereof. Further, the air input port 34 of the air chamber 31 is arranged at a front, cold air is sucked. Further, since a moisture content is separated away from air through a velocity of flow reduction operation of the air chamber 31, a moisture content is prevented from penetrating into the carburetor. |
