  And according to the cleaning tool 10 of this embodiment, even when the cleaning work is repeatedly performed using the cleaning tool 10, the state in which the handle portion 13 and the cleaning tool body 12 are firmly connected and integrated is long. Can be held for a period of time.

That is, according to the present embodiment, the following operational effects are obtained.
(1) With the cleaning tool main body 12 and the handle portion 13 connected, the main body side connecting portion 18 has a standing wall portion 26a that supports the pair of overhanging support portions 17 in the longitudinal direction (vertical direction) of the cleaning tool main body 12. Since the stress that vertically bends the cleaning tool main body 12 is supported by the structure standing up along, the main body side connecting portion 18 and the handle portion side connecting portion 14 are hardly deformed.
(2) In the connected state of the cleaning tool main body 12 and the handle portion 13, the main body side connecting portion 18 is between the pair of standing wall portions 26a that support the pair of overhanging support portions 17, and Since the plate portion 24 has a portion (on the edge portion 19 in this embodiment) that continues substantially on the same plane as the plate-like portion 24, the overhanging support portion 17 divided by the gap portion 16 opens even when bending stress is applied. Difficult to deform.
(3) In the connected state of the cleaning tool main body 12 and the handle portion 13, the handle portion side connecting portion 14 is formed so that the middle rib 22 protrudes from the groove portion 23 toward the distal end side in the insertion direction. Even if the portions protruding from the upper end and the lower end of the middle rib 22 to both sides are plate-like or thin, the upper and lower intervals of the groove 23 are difficult to spread. For example, when the middle rib 22 is recessed from the groove portion 23 and the overhanging portion protruding from the upper and lower ends of the middle rib 22 constituting the groove portion 23 is protruded from the middle rib 22, the overhanging portion protrudes. Since the plate-like portion 24 of the cleaning tool body 12 hits the portion, when the vertical bending force is applied to the protruding portion, the protruding portion is easily opened and deformed. However, in the connection structure 20 of the present embodiment, The intermediate rib 22 is preferably formed so as to protrude without being recessed from the groove 23 on the front end side, thereby preventing the open deformation in which the upper and lower intervals of the groove 23 are widened.
(4) In the present embodiment, the groove portion 23 of the handle portion side connecting portion 14 is formed by engaging the protruding portion 22a on the leading end side in the insertion direction of the middle rib 22 with the concave portion of the connecting raised portion 26b of the main body side connecting portion 18 in a connected state. Is prevented from being inserted into the tip from the overhanging support portion 17 of the main body side connecting portion 18, and the role of centering is to arrange the middle rib 22 of the handle portion side connecting portion 14 at the center of the gap portion 16 of the main body side connecting portion 18. Fulfill.
(5) In a state where the handle 13 is connected to the cleaning tool body 12, the overhanging support part 17 of the main body side connecting part 18 is connected to the pair of overhanging support parts 17 at the ends of the standing wall part 26a via the raised part 26b. Therefore, it is difficult to deform even when bending stress is applied.
(6) In the state where the cleaning tool main body 12 and the handle portion 13 are connected, the engagement structure of the first locking portion and the second locking portion for preventing the removal is the plate-like portion 24 of the main body side connecting portion 18. Since the structure is such that the punching hole 27 provided on the bottom surface of the handle portion side connecting portion 14 is engaged with the locking protrusion 28 on the bottom surface of the handle portion side connecting portion 14, The connecting portion is not subjected to a deformation force when the locking projection 28 is engaged with the punch hole 27. In other words, the connecting portion between the overhanging support portion 17 and the groove portion 23 is positioned below and away from the engaging portion between the first locking portion (the punch hole 27) and the second locking portion (the locking projection 28). Therefore, a sufficient structure and thickness that do not deform can be provided. Therefore, a strong connection structure can be obtained.
(7) The handle portion side connection is achieved by setting the thickness of the plate-like portion 24 (the edge portion 19 in this embodiment) at the end of the connection side to be thinner than the through hole of the main body side connection portion 18 or the recess for locking. When the portion 14 is inserted into the main body side connecting portion 18, the force with which the locking projection 28 provided on the bottom surface of the handle portion side connecting portion 14 gets over the plate-like portion 24 can be kept small. Furthermore, even if the portions constituting the upper and lower portions of the overhanging support portion 17 that receives the bending force and the groove portion 23 of the handle portion side connecting portion are thickened, the insertion force is not affected. The thickness of the structural part that receives the bending force and the thickness of the plate-like part 24 at the end on the connection side can be set from the through hole of the main body side connection part 18 or the recess for locking.

  Furthermore, according to this embodiment, the pressing part 24 continuing from the main body side connecting part 18 of the cleaning tool main body 12 to the front end side has a cross-sectional shape in which the thickness of the central part 24a is larger than the peripheral part 24b. And having a planar shape that is thin on the tip side, the pressing force from the handle 13 is effectively transmitted to the pressing part 24, and the bending suitable for the form of the surface to be cleaned is smoother. It is possible to cause the pressing portion 24 to be generated, and it is possible to efficiently clean the surface to be cleaned constituting these grooves and gaps by inserting the thin peripheral edge portion 24b into the thin grooves and gaps. Become.

  A second embodiment is shown in FIGS. 4A to 4C and FIGS. 5A and 5B. The connection part 20 of the second embodiment is different from the connection part 20 of the first embodiment described above in that the tip of the handle part side connection part 14 is not inserted from the rear side of the main body side connection part 18, The insertion direction is the opposite side, and the rear end of the handle portion side connecting portion 14 is inserted from the front end side of the main body side connecting portion 18. That is, the connecting portion 20 of the second embodiment is configured such that the rear end of the middle rib 22 of the handle portion side connecting portion 14 (on the side opposite to the connecting side end portion of the handle portion side connecting portion 14) and the main body side connecting portion. 18, the front end of the overhanging support portion 17 of the main body side connection portion 18 is inserted into the front end of the gap portion 16 from the front side opposite to the connection side end portion, which is behind the connection portion 18. Insert from and connect.

  In the second embodiment, the bottom surface 14b of the handle portion side connecting portion 14 that protrudes from the middle rib 22 on both sides and constitutes the lower portion of the groove portion 23 is a flat surface, and the locking projection 28 is downward on the tip portion thereof. Protrusively provided. The bottom side of the locking projection 28 is supported along the top surface of the plate-like portion 24 on the front end side of the main body side connecting portion 18 from the rear end of the groove portion 23 of the handle portion side connecting portion 14. Insert the tip of the part 17 and slide it. The locking protrusion 28 rides on the plate-like portion 24 by sliding insertion, and gradually increases the elastic deformation of the main body side connecting portion 18 and the handle portion side connecting portion 14 to be below the overhanging support portion 17 and the gap portion 16. It falls into the provided punch hole 27 elastically and is locked to the opening side opening edge of the punch hole 27, so that the handle portion side connecting portion 14 slides forward of the main body side connecting portion 18 and comes out. To prevent. Then, at the same time that the locking protrusion 28 as the second locking portion is locked into the punch hole 27 as the first locking portion, the rear end portion of the middle rib 22 is paired with the pair of main body side connecting portions 18. The movement toward the handle portion 13 of the handle portion side connecting portion 14 and the main body side connecting portion 18 is restricted by coming into contact with the connecting raised portion 26b standing upright from the plate-like portion 24 at the rear end of the wall portion 26a. .
