In FIG. 11D, the case where the soft portion 221 and the second soft portion 223 are connected in the vicinity of the tip 22aa is illustrated, but the soft portion 221 and the second soft portion 223 are not connected, and are separately provided. It may be formed.
Moreover, after providing the protrusion part 22f, you may provide a 2nd soft part further.

Since the second soft portion 223 is formed on the tip 22aa side where the inclined surface 22a becomes high, the second soft portion 223 is formed when the cleaning tool 100 is leaned against the wall with the tip 22aa side of the peripheral surface 22b facing the wall. It will touch the wall. Accordingly, even when the cleaning tool 100 is leaned against the wall with the tip 22aa side of the peripheral surface 22b facing the wall without impairing the effect of maintaining the strength when the upper end portion of the grip portion 22 is gripped. It can be made difficult to fall.
The second soft part 223 may be formed flush with the peripheral surface 22b or may be formed so as to protrude forward.

(Modification 2)
As in the gripping part 22B shown in FIG. 12, the second soft part 223B may be formed so as to cover from the inside of the through hole 22db to the periphery of the through hole 22db of the peripheral surface 22b. In this case, the second soft portion 223B is formed so as to protrude forward by 1 mm to 10 mm, more preferably 5 mm to 8 mm.
Even in this case, even when the cleaning tool 100 is leaned against the wall with the tip 22aa side of the peripheral surface 22b facing the wall without impairing the effect of maintaining the strength when the upper end of the grip 22 is gripped. Can be difficult to fall.
The second soft part 223B may be formed so as not to protrude forward.

(Modification 3)
Like the holding part 22C shown in FIG. 13, two protrusions 22fC may be formed by forming the upper part of the through hole 22db on the front side of the peripheral surface 22b.
Also in this case, when the cleaning tool 100 is leaned with the tip 22aa side of the peripheral surface 22b facing the wall, two points come into contact with the wall. Accordingly, even when the cleaning tool 100 is leaned against the wall with the tip 22aa side of the peripheral surface 22b facing the wall without impairing the effect of maintaining the strength when the upper end portion of the grip portion 22 is gripped. It can be made difficult to fall.
