Each of the both ends of the part 41 is fixedly coupled. In this embodiment, the bearing portion 40 and the first support shaft portion 41 are resin-molded so as to form a single integral with the cleaning head 20 (the mounting plate 21 and the connecting portion 22).

  The joint 30 is attached to the outer periphery of the first support shaft portion 41 so as to be rotatable.

  The joint 30 is provided with hole-shaped connecting portions 61 provided on the inner side surfaces 61A of the arm portions 60A and 60A constituting the bifurcated portion 60 at the tip of the handle 10 on both side portions 51A on the outer periphery of the rotating member 50. Thus, the rotating member 50 is pivotally attached to each of the projecting shaft-like second support shaft portions 51 provided on a single axis orthogonal to the rotation center axis (matching the center axis of the first support shaft portion 41). . In addition, the 2nd spindle part 51 may be made into a hole shape, and the connection part 61 may be made into a protruding shaft shape. Further, the rotation center axis of the rotating member 50 (matching the center axis of the first support shaft portion 41) and the second support shaft portion 51 are not necessarily orthogonal to each other, and may be on different planes and at right angles to each other. .
