Abstract: The present invention includes a roller brush provided in a frame main body. The roller brush includes a rigid shaft, a pair of guide rollers, which are arranged concentrically with a shaft center line of the rigid shaft, and are mounted to shaft ends of the rigid shaft, and a cleaning brush cloth including cut piles raised from a cloth front surface of a foundation cloth. The cleaning brush cloth is helically wound around a shaft outer-peripheral surface of the rigid shaft with a cloth back surface of the foundation cloth being in contact with the shaft outer-peripheral surface, and is fixed to the rigid shaft.

Abstract: To provide a compact manual cleaning instrument with which it is simple to collect and discharge dust, with which it is possible to clean in tight spaces, which is silent, and which is comfortable to use. A dust trapping body 3 is brought into contact with a surface to be cleaned, and the manual cleaning instrument 1 is moved back and forth, whereby dust can be trapped and collected in a dust collection chamber 37. The dust which has been collected can be discharged by opening a lid 28.

Abstract: A manually operated cleaner is provided with a body in the form of a box-shaped container having a removable lid and a bottom wall. Two parallel openings are provided through the bottom wall of the container. A roll brush is mounted to project out of one opening and a rotatable semicylindrical brush body is mounted for pivotable movement between two stop members with one of its surfaces including inclined bristles projecting through the other opening. A dust removing brush member having bristles inclined toward the interior of the container is pivotably mounted to the container and urged by spring means to maintain sliding contact with the bristles on the brush body.

Abstract: A hand-operated cleaning brush having means for automatically turning the brush body in a one-touch operation is provided. The cleaning brush comprises a handle, a brush holder having a hollow boss which is rotatably, upwardly and downwardly mounted on a shaft projecting downwardly from the brush holder into the hollow boss, a spring means arranged within the hollow boss to urge the brush body toward the brush holder, an actuating lever mounted on the brush holder and forked at its front end into two arms which cooperate with the boss such that when the actuating lever is operated the boss together with the brush body is pressed down against the force of the spring thereby releasing the boss from its locking position and causing it to rotate 180.degree. and to return to the position wherein the boss with the brush body is urged toward the brush holder to lock the brush body in place.
