<p>PROBLEM TO BE SOLVED: To provide an air cleaner having a straightening structure which can reduce the influences of swirl to improve the measuring accuracy of a sensor while leaving an arrangement space as it is.SOLUTION: An air cleaner 1 includes a body 11 in which a cylindrical inner element 14 is stored, the body 11 having an inlet pipe 12 located offset from the center line in the radial direction of the body 11, and an outlet pipe 22 along a center axis C2 of the inner element 14. Inside the inner element 14, a cylindrical linear flow path forming part 51 is provided which has a predetermined length size along the direction of the center axis C2 and is communicated with the outlet pipe 22. In the linear flow path forming part 51, a straightening device 50 is provided at a position apart from the outlet pipe 22 and close to the end. In the straightening device 50, a number of small flow paths 53 are formed along the center axis C2.</p> |
