Specifically, the bearing position in the present embodiment is outside the projection width along the axial direction (left-right direction) of the core body portion 1a and is close to the body support portion 2a.

  The conversion unit is not limited to the above-described configuration, and the one-end support unit 20 may be configured to have flexibility (flexibility to bend in the right direction). In addition, the conversion unit contacts the left surface 13d of the locked portion 13 (base portion 13a) (the contact surface that contacts the right surface 23d of the locking portion 23) and the inner surface of the concave portion 13b (the upper surface of the convex portion 23e of the locking portion 23). It is also possible to comprise one or both of the contact surfaces. In this case, the left surface 13d is configured to include a surface that is inclined with respect to the left-right direction (for example, a lower-right inclined surface that is separated from the right surface 23d in the right direction toward the lower side). The surface that contacts the upper surface of the convex portion 23e can be configured to include a surface that is inclined with respect to the left-right direction (for example, a lower-right inclined surface that is separated from the right surface 23d in the right direction toward the lower side). .

In addition, the conversion portion includes a convex portion (specifically, a convex portion that fits into the other concave portion) provided on one of the other end portion 11 of the core body 1 and the other end support portion 21 of the main body portion 2. The convex portion is formed so that the convex portion is separated from the concave portion when the core body 1 is moved against the restriction of the core body 1 to release the concave-convex fitting. It is also possible to reduce the projection amount (volume) of the convex portion from the forming surface. For example, when the protrusion protrudes from the contact surface of the other end 11 or the other end support 21 and the protrusion is pressed with a predetermined pressure or more (for example, due to elasticity), the protrusion amount increases. The protrusion is retracted with respect to the contact surface so as to decrease, and when the pressing force is removed, the protrusion can be moved back and forth with respect to the contact surface so that the protrusion returns to the original protrusion amount. It is possible to include a support body (for example, an elastic body) to support. For example, the support is embedded in the contact surface. When the core body 1 is moved to release the concave / convex fitting, the protrusion is pressed by the inner surface of the concave portion, and the pressing of the predetermined pressure or higher releases the concave / convex fitting. Therefore, it is a force that moves the core body 1 in the movable direction against the regulation of the core body 1.

8A and 8B, the cleaning tool according to the present embodiment is configured to include a case 3 in which the main body 2 is detachable to accommodate the core body 1. As shown in FIGS. The case 3 has a body shape that can accommodate the core body 1, and has a main body 3 </ b> A that forms an opening on one surface (specifically, an upper surface opening). On both sides of the lower surface of the case 3 in the left-right direction, convex feet 3a (specifically, a pair of ridges parallel in the front-rear direction) are provided to stably stand the case 3 (main body 3A). Is formed. Further, the fitting pieces 2d of the main body part 2 (specifically, the lower ends of the pair of front and rear side wall parts 2c are arranged downward from both the left and right side ends of the upper end side inner surface of the case 3 (main body part 3A). A base portion extending to the base, and a base portion having a concave portion for fitting (see FIG. 1), and a fitting portion 3b (specifically, a concave portion into which the base portion of the fitting piece 2d is fitted). And the recessed part which has the convex part for a fitting fitted to the said concave part for fitting of the fitting piece 2d is provided in the recessed part. The configuration for fitting the main body 2 and the case 3 is not particularly limited, and either one of the main body 2 and the case 3 is provided with a fitting convex portion, and the other is fitted to the other. What is necessary is just to provide the combination recessed part. Moreover, although the cleaning tool of this embodiment is provided with the case 3, it is not limited to this, The cleaning tool is provided with the core 1 and the main-body part 2 without providing the case 3. It is also possible to configure.
[6. General operation of cleaning tool]

In the cleaning tool having the above configuration, the one end portion 10 of the core body 1 is connected to and supported by the one end support portion 20 of the main body portion 2, and the core body 1 is movable with respect to the main body portion 2 with the one end portion 10 as a starting point. (See FIGS. 5A, 6B, and 7). Specifically, the pair of shaft portions 12b of the one end portion 10 is supported (supported) by the bearing portion 22 of the one end support portion 20, and the central axes (front and rear) of the pair of shaft portions 12b fitted in the recess 22b. It can be rotated around a movable axis). That is, the core body 1 is configured to rotate with respect to the main body portion 2 starting from one end portion 10 (a pair of shaft portions 12b) (see FIGS. 5A and 7). Further, the other end portion 11 of the core body 1 is detachably locked to the other end support portion 21 of the main body portion 2.
[6-1. About locking operation]

  The operation of locking the other end portion 11 of the core body 1 to the other end support portion 21 of the main body portion 2 will be described. The core body 1 is rotated with the one end portion 10 as a starting point, and the outer surface side (left surface 13d) of the locked portion 13 in the other end portion 11 and the inner surface side (right surface 23d) of the other end support portion 21 come into contact. Thus, the other end part 11 and the other end support part 21 are brought close to each other. Here, when the concave portion 13b of the locked portion 13 of the other end portion 11 is directed toward the convex portion 23e of the other end support portion 21 or the convex portion 23e is brought close to the concave portion 13b, the locked portion 13 (base portion) 13a), the convex portion 23e extends along the tapered portion 13e between the pair of rail portions 13c, and the convex portion 23e extends along the pair of rail portions 13c between the pair of rail portions 13c. It moves (or slides) so as to guide it. When the convex portion 23e is placed along the tapered portion 13e, the base portion 23a of the locking portion 23 bends in the left direction due to the flexibility, so that the convex portion 23e contacts the tapered portion 13e, The left surface 13d is smoothly slid while appropriately bending the base 23a in accordance with the inclined surface of the tapered portion 13e.

And while the recessed part 13b of the other end part 11 (locked part 13) is fitted by the convex part 23e of the other end support part 21 (locking part 23), a pair of rail part 13c becomes a pair of groove part 23f. By fitting, the left surface 13d of the locked portion 13 and the right surface 23d of the locking portion 23 are in contact with each other (see FIGS. 5A and 6B). At this time, the other end portion 11 of the core body 1 is locked to the other end support portion 21 of the main body portion 2. Thus, in the state where the other end portion 11 is locked to the other end support portion 21, the other end portion 11 is supported by the other end support portion 21 as a support end, and the core body 1 starting from the one end portion 10 is used. The rotation is restricted (see FIG. 5A). In this state, the main body support portion 2a and the core body portion 1a are spaced apart from each other in the vertical direction and are parallel to each other in the left-right direction (see FIG. 5A). When the body body 1a is inserted and attached, the adhesive tape roll can be used appropriately.
[6-2. About unlocking operation]

  Subsequently, an operation of releasing the locking (uneven fitting) of the other end portion 11 of the core body 1 locked to the other end support portion 21 of the main body portion 2 (an operation of releasing the rotation restriction of the core body 1). ). Rotation of the core body 1 in the movable direction of the core body 1 in a direction away from the concave portion 13b of the other end portion 11 from the convex portion 23e of the other end support portion 21 or in a direction away from the convex portion 23e from the concave portion 13b. The core body 1 is moved against the restriction, and the locked portion 13 and the locking portion 23 are moved (slid) to be separated from each other. The movement of the core body 1 releases the fitting between the convex portion 23e and the concave portion 13b and the fitting between the pair of rail portions 13c and the pair of groove portions 23f.

  Here, the inclined surface 231e inclined to the lower right of the convex portion 23e slides on the upper surface of the inner surface of the concave portion 13b. The inclined surface 231e is moved along the inclined surface 231e so as to separate the concave portion 13b and the convex portion 23e from each other. Specifically, the inclined surface 231e applies the force for moving the core body 1 when the core body 1 is moved in the movable direction against the restriction of the movement (movable) of the core body 1 to the concave portion 13b and the convex portion. By converting the force to move away from 23e, the concave-convex fitting can be easily released. More specifically, when the core body 1 is moved in the movable direction against the restriction of the movement (movable) of the core body 1, the force in the movable direction (force along the radial direction of the core body 1). A part is changed toward the one end side in the axial direction of the core body 1 by the inclined surface 231e and acts on the other end 11 (recess 13b), and the other end 11 (recess 13b) is the other reaction. An axially outward force of the core body 1 is applied to the end support portion 21 (convex portion 23e). The concave / convex fitting is easily released by the action / reaction force between the other end portion 11 (concave portion 13b) and the other end support portion 21 (convex portion 23e).

  Further, the right surface 23 d inclined to the lower left of the locking portion 23 slides on the left surface 13 d of the locked portion 13. The right surface 23d moves along the right surface 23d so as to separate the concave portion 13b and the convex portion 23e. Specifically, the right surface 23d allows the other end portion 11 (concave portion 13b) and the other end support portion 21 (convex portion 23e) to exert the action / reaction force on each other, thereby restricting the regulation of the core body 1. In contrast, when the core body 1 is moved in the movable direction, a part of the force for moving the core body 1 in the movable direction is converted into a force for moving the concave portion 13b and the convex portion 23e apart. The uneven fitting can be easily released.

  Moreover, since the base 23a of the latching | locking part 23 has the flexibility which bends in the left direction, it moves so that the recessed part 13b and the convex part 23e may be spaced apart by the bending | flexion by this flexibility. Specifically, the base 23a is bent leftward (outward in the axial direction of the core body 1) when the core body 1 is moved in the movable direction against the restriction of the core body 1, thereby By converting a part of the force for moving the core body 1 in the movable direction into a force for moving the concave portion 13b and the convex portion 23e away from each other, the concave-convex fitting can be easily released.

  Further, in the bearing structure in which the shaft portion 12b of the one end portion 10 of the core body 1 is supported by the bearing portion 22 of the one end support portion 20 of the main body portion 2, the bearing portion 22 of the one end support portion 20 of the main body portion 2 is Since the shaft portion 12b of the one end portion 10 of the core body 1 is supported at the bearing position above the fitting position where the concave portion 13b and the convex portion 23e are fitted, the fitting position and the bearing position are in the vertical direction. In the case of a substantially equal bearing structure (for example, within the position along the axis (left-right direction) of the core body 1 or the projection width along the axial direction of the core body 1), there is a fitting position on the other end portion 11 side. Compared to the case of a bearing structure having a bearing position on the side), the core body 1 is rotated from one end portion 10 of the core body 1 as a starting point against the restriction of the movement of the core body 1 to release the uneven fitting. The locus of the other end portion 11 (specifically, an arcuate rotation locus) is more to the right ( The body specifically the lower right close). That is, the bearing structure shifts the rotation position of the other end portion 11 to the right by shifting the bearing position upward from the fitting position toward the main body support portion 2a in the vertical direction, thereby causing the concave portion 13b and the convex portion to protrude. It moves so that the part 23e may be spaced apart. Specifically, the bearing structure is configured such that when the core body 1 is moved in the movable direction against the restriction of the core body 1, the rotation locus of the other end portion 11 is shifted to the lower right side. By causing the end 11 (concave portion 13b) and the other end support portion 21 (convex portion 23e) to exert the above-mentioned action / reaction force, a part of the force for moving the core body 1 in the movable direction is convex with the recess 13b. By converting the force to move away from the portion 23e, the concave-convex fitting can be easily released.

  As described above, when the fitting between the concave portion 13b of the other end portion 11 and the convex portion 23e of the other end support portion 21 is released, the other end portion 11 of the core body 1 and the other end support portion 21 of the main body portion 2 are removed. Is released. Thus, in the state where the locking is released, the other end portion 11 released from the support by the other end support portion 21 is released from the other end support portion 21 as a free end, and the core body 1 starts from the one end portion 10. Rotates relative to the main body 2. In such rotation of the core body 1 with respect to the main body portion 2, as shown in FIG. 7, the core body 1 is moved to a desired position with respect to the main body portion 2 starting from one end portion 10. The other end portion 11 and the other end support portion 21 of the main body portion 2 can be separated from each other. In this state, when the adhesive tape roll is not attached to the core body 1, the adhesive tape roll is inserted from the other end portion 11 of the core body 1 to the one end portion 10, or the used adhesive tape roll is used for the core body 1. Can be easily removed from the other end 11 of the core body 1.

After using the cleaning tool (after cleaning the surface to be cleaned with the adhesive tape roll attached to the core 1), the main body 2 is fitted to the case 3 as an upper lid of the case 3, and the core 1 (or adhesive) The tape roll) can be stored in the case 3 and stored appropriately. Specifically, the upper surface opening of the case 3 is closed by the main body 2 by fitting the pair of fitting pieces 2 d of the main body 2 into the pair of fitted portions 3 b of the case 3.
