<P>PROBLEM TO BE SOLVED: To provide an air cleaner which is simple in structure, can reduce the number of part items, and can prevent a risk of the occurrence of a trouble at the generation of a backfire. <P>SOLUTION: An engine-side first case 12 and an air-release side second case 13 are connected to each other so as to be openable and closable via a filter 19, a through-hole 20 is formed at a part of the first case 12, and a blocking member 22 for blocking the through-hole 20 is arranged. Usually, the blocking member 22 is held in a blocking position of the through-hole 20 by a spring force, the blocking member 22 is operated at the generation of the backfire so as to be releasable by its inner pressure against the spring force, and the inner pressure is made to escape from the through-hole 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
