By causing an air introduction passage to be curved in an air cleaning device, the miniaturization of the air cleaning device can be realized, the life of a cleaner element can be lengthened and the uniformity of a flow of air in a clean chamber can be improved. An air introduction passage 21 having an outlet 21o opened to a dust chamber 12 of an air cleaner chamber 11 of an air cleaner 10 has a curved passage divided into a curved inside branch passage 23 and a curved outside branch passage 24 by a rectification plate 22. In the dust chamber 12, deflecting portions 33 and 34 are provided to deflect flows of air flowing to the dust chamber 12 from the outlet 21o via the curved inside branch passage 23 and the curved outside branch passage to thereby direct the flows to a cleaner element F. The deflecting portion 34 is positioned nearer to the outlet 21o than the deflecting portion 33 in a back-and-forth direction.
