Abstract
An air cleaner includes an air intake port and an exhaust port on a side opposite to the intake port. A filter extends to the exhaust port side from the intake port side and divides the air cleaner into suction side and exhaust side air chambers. A distance between a side wall part of the suction side air chamber and the filter gradually decreases to the back of the suction side air chamber from the intake port. A distance between a side wall part of the exhaust side air chamber and the filter gradually increases to the exhaust port.
