ABSTRACT:
A manual cleaner has a case, a roller brush having driven rollers and mounted between the side plates of the case, wheels kept in contact with the driven rollers and mounted on axles extending in parallel with the roller bruch, and dust pans provided at both sides of the roller brush. The dust pans are formed at both sides with bearing projections rotatably received in the side plates of the case so as to be pivotable about the projections. The projections are each formed with an axle receiving hole elongated horizontally so that the axles received in the holes can move toward and away from the roller brush. Thus the wheels can move toward and away from the driven rollers while keeping the dust pans in a stationary position. The shaft of the roller brush has both ends vertically movably mounted in bearing plates provided at both sides of the case and biased by springs downwardly. Spring members integrally formed on the bearing plates extend in opposite directions to abut and urge the dust pans closed.
