ABSTRACT A cleaning brush comprises a handle provided with a brush holder for holding a brush body that includes a brush surface having numerous short bristles inclined in the same direction; a hollow boss provided on the back side of the brush body and within the brush holder and rotatably, upwardly and downwardly movably mounted on a projection shaft extending downwardly from the brush holder into the hollow boss; a spring arranged within the hollow boss to urge the boss with the brush body toward the brush holder so that the brush body is held on the brush holder for enabling a brushing operation; the hollow boss including an upper portion and a lower portion which is larger in diameter than the upper portion; the lower boss portion being formed in its periphery with vertical grooves extending axially thereof in diametrically opposed relation to each other; projecting members extending downwardly from the brush holder and engageable with the grooves respectively so as to lock the boss against rotation when the projecting members are in engagement with the respective grooves; the lower boss portion being divided by the grooves into one-half circumferential sections each having a downwardly slanting top surface inclined circumferentially in the same direction; an actuating lever mounted on the holder and forked at its front end into two arms which extend above the upper boss portion; raised portions provided on the top face of the upper boss portion or on the arms; inclined surfaces provided on the arms or on the top face of the upper boss portion and cooperating with the raised portions; the arrangement being such that when the actuat- ing lever is operated the boss together with the brush body is pressed down against the force of the spring and the projecting members are disengaged from the grooves to release the boss from locking whereupon the boss is somewhat rotated to allow the project- ing members to ride on the slanting top surfaces on the lower boss portion so that when the actuating lever is released the projecting members slide down along the slanting top surface on the lower boss portion with a result that the boss together with the brush body is rotated to complete 180° rotation and is returned to the original position.
