【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a cleaning tool according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of an essential part of FIG. 1, and FIG. 3 is an enlarged front view of an essential part of FIG.

In these drawings, the cleaning tool 1 is configured such that a cleaning tool main body 3 (broom head in this embodiment) is detachably connected to a lower end of a handle 2, and its configuration is as follows. Is. That is, the tapered portion 4 is formed near the lower end of the handle 2 so as to expand downward. Further, a downward protruding rod 5 is provided below the tapered portion 4. The protruding rod 5 is formed in a taper shape whose diameter decreases downward. Further, an engagement protrusion 6 (engagement means) for preventing rotation is provided at the boundary between the tapered portion 4 and the projecting rod 5. As shown in FIG. 3, the taper portion 4, the projecting rod 5, and the engaging projection 6 are integrally molded of resin, and the resin member 2a is fitted into the lower end of the round pipe 2b forming the handle 2. It is fixed by an adhesive.

A tubular connecting member 7 is externally fitted to the handle 2. A taper hole portion 8 having a shape corresponding to the taper portion 4 is formed on the upper end side in the connection member 7, and a female screw portion 9 is formed on the lower end side.

The cleaning tool body 3 is formed with a male screw portion 10 that is screwed into the female screw portion 9. A housing hole 11 for housing the projecting rod 5 is formed at the center of the male screw portion 10. The housing hole 11 has a tapered shape corresponding to the protruding rod 5. Further, an engagement recess 12 (engagement means) that engages with the engagement projection 6 is formed at the opening end of the accommodation hole 11.

With the above-described structure, when the handle 2 and the cleaning tool body 3 are connected, the engagement protrusion 6 and the engagement recess 12 are engaged with each other so that the cleaning tool body 3 is connected. The protruding rod 5 of the handle 2 is inserted into the accommodation hole 11 of the above. Then, when the connecting member 7 is rotated in this state, the female portion 9 and the male screw portion 10 are screwed together, and the connecting member 7 is moved to the cleaning tool main body 3 side, which causes the taper of the connecting member 7. The inner peripheral surface of the hole portion 8 is pressed against the outer peripheral surface of the tapered portion 4 of the handle 2, and the outer peripheral surface of the protruding rod 5 of the handle 2 is pressed against the inner peripheral surface of the housing hole 11 of the cleaning tool body 3 so as to be in close contact with each other.
