Abstract
An air cleaner provided with a bellows-like air cleaning filter includes an air permeable and pliable strip-like mesh element (3), a plurality of rectangular plastic frames (4) arrayed side by side with a predetermined pitch on one or both surfaces and along the full length of the mesh element (3), the plastic frames (4) being injection-molded and provided at both end portions in the width-wise direction with angled protrusions (5) having an approximately triangular cross-section and hinge portions (7) formed by thinning or linearly grooving a joint portion of the frames (4) between neighboring plastic frames (4). The bellows-like air cleaning filter is employed by transforming it into a cylindrical shape and fitting end caps (9) thereto.
