There is known a cleaning mop in which 93 is detachably mounted. In the cleaning mop, cylindrical rotary grips 90 a and 90 a are provided on the mop handle 90, and the mop handle 90 can be tilted at a pivotal attachment portion 94 with the mop mounting board 91.

  For cleaning the mop 92, a cleaning bucket 100 as shown in FIG. 6 is used. The dehydration basket 101 is rotatably provided in the cleaning bucket 100, and a conical mop cleaning member 103 is rotatably provided at the bottom of the mop cleaning portion 102 which is the adjacent space portion. When cleaning the mop 92, as shown in FIG. 7, water is poured into the mop cleaning unit 102, and then a recess (not shown) formed on the back surface of the mop head 93 is fitted into the mop cleaning member 103. And step on the pedal 104 repeatedly with your foot. Accordingly, the mop cleaning member 103 is rotated by a gear group mechanism (not shown) built in the bottom of the cleaning bucket 100, and the mop head 93 is rotated together with the mop mounting board 91, so that the mop 92 is cleaned by the rotational force. Will be.

  Further, when the dehydrated mop 92 is dehydrated, as shown in FIG. 8, when the mop 92 is housed in the dehydrated basket 101 and the pedal 104 is repeatedly stepped on with a foot, the dehydrated basket 101 is rotated by the gear group mechanism. The head 93 also rotates at the same time, and the water contained in the mop 92 is dehydrated by the centrifugal force. At the time of dehydration and the above-described cleaning, if the mop pattern 90 stands vertically and is held with one or both of the rotary grips 90a and 90a, the mop pattern accompanying the rotation of the mop head 93 is used. The rotation of 90 rotates stably without being transmitted to the rotating grips 90a and 90a (refer to Patent Document 1 for details of the above-described conventional cleaning mop and cleaning bucket).

  The above-described mop head 93 is merely such that the mop mounting board 91 is strongly fitted in a circular recess 95 (see FIG. 10) formed on the upper surface thereof. For this reason, when the mop head 93 is replaced, as shown in FIG. 9, the mop pattern 90 is moved in the non-rotating direction in the pivot 94 with the mop 92 of the mop head strongly stepped on with a foot (when the mop pattern 90 is tilted). The mop mounting plate 91 is removed from the circular recess 95 of the mop head 93 by pushing it down in the direction in which the mop handle 90 does not rotate. When attaching a new mop head 93, as shown in FIG. 10, after positioning the mop mounting board 91 directly above the circular recess 95 of the mop head 93, the upper surface of the mop mounting board 91 is strongly attached with the foot. It is stepped on and fitted into the circular recess 95.

  However, the simple fitting-type structure as described above involves a force work when the mop head 93 is exchanged, which is a difficult work for a powerless person such as a woman or an elderly person. Further, if the mop head 93 is loosely fitted, an accident such as the mop head 93 coming off during cleaning is also a concern.

  Regarding the mop mounting structure, in addition to the above-described conventional examples, the following Patent Document 2 and Patent Document 3 have been proposed, but these mop heads are fixed to the mop mounting panel or a member corresponding thereto by screws. In either case, the mop head replacement work is complicated.
