Abstract: PURPOSE: An air cleaner is provided to prevent the damage of an intake system including an air cleaner by discharging a backfire in an engine to the outside immediately. CONSTITUTION: An exhaust hole(21) is protruded to one side of a fresh air duct of an air cleaner(10), and a valve(20) is movably hinged to isolate the exhaust hole. The valve adopts a damper(30) for closing the exhaust hole at normal times and opening the valve in the occurrence of a backfire in an engine. The valve isolating the exhaust hole is opened at the moment to discharge an inner pressure when the backfire is generated from a surge tank of the engine. Thereby, an intake system is prevented from damage. To remove a backfire pressure, the valve isolates the exhaust hole with the supporting force of the damper so that external air is supplied into the engine.
