A flexible hose having an air-permeability and formed either: by sandwiching an air-permeable tape between the tape end edge portions, as leading and trailing in the hose longitudinal direction, of a soft resin tape to be helically wound, and by winding the air-permeable tape integrally with the soft resin tape; or by winding only the air-permeable tape helically. Especially, the air-permeable flexible hose can be properly used as a cleaner hose of the discharge circulation type by using it as an outer tube of a double tube. By giving lubricating properties to the inner circumference of the outer tube or the outer circumference of the inner tube, on the other hand, it is possible to prevent the wear which might otherwise be caused by the rubbing contact.
A flexible hose formed by winding a soft resin tape helically, comprising:
