Abstract: An air cleaner includes a case having an internal space, a filter element capable of partitioning the internal space into a first space and a second space, an intake port that introduces an air into the first space therethrough, an exhaust port that discharges an air from the second space, and at least one baffle part projecting toward the filter element from an inner surface of the case. The baffle part diffuses the air introduced into the first space and introduces the air to the filter element. The baffle part includes a widened baffle part. The widened baffle part includes a guide section extending along an extending surface of the filter element and a widened section larger in width than the guide section.

Abstract: An air cleaner includes a case having an internal space, a filter element capable of partitioning the internal space into first and second spaces, an intake port that introduces an air into the first space therethrough, an exhaust port that discharges an air from the second space, and at least one baffle part projecting toward the filter element from an inner surface of the case. The baffle part diffuses the air introduced into the first space and introduces the air to the filter element. The baffle part includes a first baffle part extending along an extending surface of the filter element. The first baffle part is curved so as to be away from a hypothetical straight line connecting the intake port and the exhaust port as the first baffle part extends from the intake port toward the exhaust port as viewed in a direction perpendicular to the extending surface.
