A cleaning tool includes a support tool for rotatably supporting an adhesive tape roll via bearing members; and a storing case for storing the adhesive tape roll. Bearing caps detachably attached to both ends of the adhesive tape roll are used as the bearing members. The support tool has a gate-shaped frame which is made of a synthetic resin and includes a pair of left and right leg plates and a support base extending between the upper ends of the leg plates. An opening having substantially the same width as the gate-shaped frame while the storing case is closed, is formed between matching surfaces of a pair of openable case members from both side surfaces thereof over an upper surface thereof, the case members constituting the storing case. A portion of the outer contour of the storing case is complemented by the gate-shaped frame of the support tool.
