Has been. In addition, openings 181 are formed at both ends of the cleaning body 140 in the long side direction in the holding space 180. This holding space 180 is an implementation configuration example corresponding to the “insertion portion” in the present invention.
In other words, the holding space 180 is formed by a predetermined region of the holding sheet 160 and a predetermined region of the base sheet 151 between the pair of welded joints 171, 172, and 173. Among these, a predetermined area of the holding sheet 160 located above the cleaning tool 100 (upper side in FIG. 3) in the holding space 180 is defined as a first area 180A. In addition, a predetermined region of the base sheet 151 located on the lower side of the cleaning tool 100 (lower side in FIG. 3) in the holding space 180 is defined as a second region 180B. The first area 180A and the second area 180B are implementation configuration examples corresponding to the “first area” and the “second area” in the present invention.

  The plurality of welded joints 171, 172, and 173 are arranged so as to form a curved line in the long side direction of the cleaning body 140. That is, the welding joint 171 on the opening 181 side is disposed in the vicinity of the central welding line 170 in the short side direction of the cleaning body 140. On the other hand, the weld joint 172 is disposed in an intermediate region 182 between the openings 181 at both ends in the long side direction of the cleaning body 140, and is disposed farther from the central weld line 170 than the weld joint 171. . The weld joint 173 is disposed further away from the central weld line 170. Accordingly, the holding space 180 has a configuration in which the cross-sectional area of the intermediate region 182 is larger than the cross-sectional area of the opening 181 in the short side direction of the cleaning body 140. In other words, the holding space 180 is configured such that the displacement amount of the intermediate region 182 is larger than the opening 181 in the thickness direction of the cleaning body 140.

(Engagement of cleaning body holder and cleaning body)
Next, the engagement between the cleaning body holder 110 and the cleaning body 140 will be described with reference to FIGS. 8 and 9. As shown in FIG. 8, each holding member 131 can be inserted into the holding space 180. When the holding member 131 is inserted into the holding space 180, the cleaning body 140 is held by the cleaning body holder 110.

  The width of the opening 181 of the holding space 180 is formed to be smaller than the larger one of the left-right direction separation distance W and the up-down direction separation distance D of the first holding member 135 and the second holding member 136. Therefore, in the process of inserting the holding member 131 into the holding space 180, the first elastic member 135 and the second holding member 136 are elastically deformed so as to be close to each other when passing through the opening 181.

  After the first elastic member 135 and the second elastic member 136 pass through the opening 181, the first elastic member 135 and the second elastic member 136 are separated from each other in the intermediate region between the base portion 132 and the distal end portion 133 due to the restoring force. Deform in the direction. That is, it is deformed so as to return to the initial state. Accordingly, as shown in FIG. 9, the holding space 180 is expanded in the vertical direction by the first elastic member 135 and the second elastic member 136.

  When the insertion of the holding member 131 into the holding space 180 is completed, the convex portions 137 and 138 are held between the welded joint portions 172. 9, the first elastic member 135 pushes the holding sheet 160 upward by the restoring force of the first elastic member 135 and the second elastic member 136, and the second elastic member 136 is a base sheet. Press 151 down. As a result, as shown in FIG. 8, the holding member 131 is engaged with the intermediate region 182 in the holding space 180. At this time, the presser plate 139 presses the cleaning body 140 from above, and a locking projection (not shown) provided on the lower surface of the presser plate 139 acts as a retaining member for the cleaning body 140. Thereby, the cleaning body 140 is reliably held by the cleaning body holding part 131. The holding member 130 may be inserted into the holding space 180 from any opening 181 formed at both ends of the cleaning body 140.

  According to the above embodiment, in a state where the cleaning body 140 is held by the cleaning body holder 110, the cleaning body holding part 130 extends and holds the cleaning body 140 in the vertical direction. That is, the holding member 131 is formed of a first elastic member 135 and a second elastic member 136 that can be elastically deformed, and the cleaning body 140 is moved in the thickness direction by the restoring force of the first elastic member 135 and the second elastic member 136. Has been extended. Therefore, as shown in FIG. 9, the cleaning body 140 is held in a state where the bulk is increased (a state indicated by a dotted line).

  In particular, the bulk of the fiber assembly 152 is increased. The state in which the bulk of the fiber assembly 152 is increased can be defined as a state with a high volume feeling, and can be defined as a “bulky state”, “volume up state”, “space fullness state” or “high bulky degree”. It can also be called "state". Therefore, it is possible to improve the cleaning effect by increasing the bulk of the fiber assembly 152. In addition, by increasing the bulk of the fiber assembly 152, the degree of adhesion to the surface to be cleaned is increased, the stain of the fiber assembly 152 is easily noticeable (is likely to become black), and the user is surely trapped with dust. The satisfaction will be increased.

  Further, according to the present embodiment, the first elastic member 135 and the second elastic member 136 are not only separated in the vertical direction of the cleaning body holder 110 but also separated in the left-right direction of the cleaning body holder 110. Yes. That is, the first elastic member 135 and the second elastic member 136 are spaced apart from each other in the thickness direction of the cleaning body 140, and not only hold the cleaning body 140 bulky but also intersect the thickness direction of the cleaning body 140. The cleaning body 140 is secured in the plan view so as to be spaced apart from each other. In other words, the cleaning body 140 is held bulky while suppressing the area in plan view from becoming smaller. Therefore, the cleaning body 140 can be held bulky in a wide range, and the cleaning efficiency can be improved.

In a state where the cleaning body 140 is held by the cleaning body holder 110, the holding member 131 presses in the direction of expanding the inside of the holding space 180. That is, the first elastic member 135 of the holding member 131 presses the second region 180 </ b> B of the holding space 180. Further, the second elastic member 136 of the holding member 131 presses the first region 180 </ b> A of the holding space 180. As a result, tension is applied to the first region 180A and the second region 180B in the holding space 180. That is, the first elastic member 135 and the second elastic member 136 in the holding member 131 serve as a tension applying unit 190 that applies a predetermined tension to the second region 180B in the holding space 180. Further, the second elastic member 136 is a first tension applying portion 190A. Further, the first elastic member 135 is a second tension applying member 190B.
The structure of the holding member 131 is an implementation configuration example corresponding to the “tension applying portion” in the present invention. In addition, the first tension applying unit 190A and the second tension applying unit 190B are implementation configuration examples corresponding to the “first tension applying unit” and the “second tension applying unit” in the present invention.

On the other hand, the first elastic member 135 is disposed on the inner side in the longitudinal cross direction X than the second elastic member 136. That is, the second tension applying unit 190B is arranged on the inner side in the longitudinal cross direction X than the first tension applying unit 190A. This is an exemplary embodiment of the present invention in which “the second tension applying portion is disposed on the inner side in the longitudinal crossing direction than the first tension applying portion”. Therefore, the second region 180B is the second region 180B. The tension is applied from the bottom to the top (from bottom to top in FIG. 3) while being tensioned from the tension applying portion 190B (first elastic member 135) to the first tension applying portion 190A (second elastic member 136). That is, the second region 180B forms a tension portion 191. This tension portion 191 is an implementation configuration example corresponding to the “tension portion” in the present invention.

  As a result, the second region 180B is inclined in the direction in which the first region 180A is arranged (upward in FIG. 3). Furthermore, the strips 160a and 151a that are continuous with the second region 180B are also moved in the direction in which the first region 180A is arranged (upward in FIG. 3). This is the “in the state where the holding portion of the holder is inserted into the insertion portion of the cleaning sheet, in the present invention, the tension is applied to the second region of the cleaning sheet by the tension applying portion of the holding portion. And the strips in the longitudinal crossing direction in the tension portion are moved in the direction in which the first region is arranged. "

As a result, in the cleaning body 140, the distance between the strip pieces 160 a and 151 a and the cleaning target side sheet 153 is separated. That is, the area where the cleaning body 140 should come into contact with the object to be cleaned can be increased.
Furthermore, in the cleaning tool 100 having this type of fiber assembly 152, the user may open the fiber assembly 152 by shaking the cleaning tool 100 before use. In the present invention, a region where the fiber assembly 152 is to be opened can be secured. Therefore, the opened state of the fiber assembly 152 is favorable.

  Furthermore, since the cleaning body holding part 130 is formed with two holding members 131 in a bifurcated shape, the area in the plan view of the cleaning body 140 is large when the cleaning body holder 110 holds the cleaning body 140 bulky. It can further be suppressed from becoming smaller.

  Further, according to the present embodiment, the first elastic member 135 and the second elastic member 136 are the most in the vertical direction and the horizontal direction of the cleaning body holder 110 at the intermediate portion located at an equal distance from the base portion 132 and the distal end portion 133. It is separated. Therefore, the cleaning body 140 can be most bulky at the center of the cleaning body 140 held by the cleaning body holder 110. Thereby, the cleaning body 140 can be efficiently held bulky.

  Further, according to the present embodiment, the holding member 131 is held in the holding space 180 by the restoring force of the first elastic member 135 and the second elastic member 136 in a state where the cleaning body 140 is held by the cleaning body holder 110. Engage with the intermediate region 182. That is, the restoring force of the first elastic member 135 and the second elastic member 136 can prevent the cleaning body 140 from coming off the cleaning body holder 110 during cleaning.

  Moreover, according to this Embodiment, since the width | variety of the strip piece 153a of the cleaning object side sheet 153 is made smaller than the strip piece 151a of the base material sheet 151, the fiber of the fiber assembly 152 is the cleaning object side sheet 153. It becomes possible to realize a structure that is easily entangled with the strip 153a. That is, when the strip 153a on the surface of the cleaning body 140 facing the object to be cleaned is entangled with the fibers, the side of the cleaning body 140 facing the object to be cleaned is further increased in volume. Therefore, the cleaning function for capturing dust and dust is improved. On the other hand, the strip pieces 151 a of the base sheet 151 and the strip pieces 160 a of the holding sheet 160 are less entangled with the fibers of the fiber assembly 152 than the strip pieces 153 a of the cleaning target side sheet 153. Therefore, the strip piece 151 a and the strip piece 160 a can exhibit a dust sweeping function independently of the movement of the fiber assembly 152.

  In the present embodiment, the weld joints 171, 172, and 173 are not only arranged symmetrically with respect to the central weld line 170, but also pass through the center of the central weld line 170 and are perpendicular to the central weld line 170. It is preferable that they are arranged symmetrically with respect to the straight line. According to such a configuration, the holding member 131 can be inserted into the holding space 180 from any opening 181.

  In addition, this invention is not limited only to said embodiment, A various application and deformation | transformation can be considered. For example, the following modifications that apply the above embodiment may be implemented.

(First modification)
Next, a first modification will be described based on FIGS. The cleaning tool 140 of the cleaning tool according to the first modification is provided with a high rigidity region 174 in the strip pieces 151a and 160a. In addition, the area | region of the strip pieces 151a and 160a in which the high rigidity area | region 174 is not provided is made into a low rigidity area | region. The high-rigidity region 174 and the low-rigidity region are implementation examples of the “high-rigidity region” and the “low-rigidity region” of the present invention. The strip provided with the high rigidity region 174 may be the strip 160a of the holding sheet 160 or the strip 151a of the base sheet 151. It is also possible to provide both the strip piece 160a and the strip piece 151a.

  The high-rigidity region 174 extends continuously in the longitudinal crossing direction X, which is the direction in which the strip pieces 151a and 160a extend. As a result, the strip pieces 151a and 160a are more reliably moved in the direction in which the first region 180A is arranged (upward in FIG. 3).

  Furthermore, the welding joints 171, 172, 173 (first joints) and the high-rigidity region 174 can be provided continuously. As a result, the strip pieces 151a and 160a are more reliably moved in the direction in which the first region 180A is arranged (upward in FIG. 3).

Specifically, the high-rigidity region 174 is configured by applying an adhesive such as a hot melt adhesive to a predetermined region of the strips 151a and 160a.
The high-rigidity region 174 is configured by sticking a non-woven fabric formed in a predetermined size to a predetermined region of the strips 151a and 160a.
Further, the high-rigidity region 174 is configured by a second joint portion in which predetermined regions of the sheet members (base material sheet 151 and holding sheet 160) constituting the strip pieces 151a and 160a are welded. The second joint portion that is the high-rigidity region 174 is an implementation configuration example of the “second joint portion” of the present invention.

(Second modification)
Next, a second modification will be described based on FIG.
In the cleaning tool according to the third modified example, the high rigidity region 174 of the strip pieces 151 a and 160 a is formed by the second joint portion 175. In this case, a part of the fiber assembly 152 can be welded to the second joint portion 175.
Therefore, a part of the fiber assembly 152 is connected to the strip pieces 151a and 160a where the second welded portion 175 exists. Therefore, when cleaning work is performed using the strip pieces 151a and 160a, the possibility that dust or the like can be captured by the fiber assembly 152 is improved.

(Third Modification)
Next, a third modification will be described based on FIG.
The cleaning tool 200 of FIG. 13 includes a cleaning body holder 210 and a cleaning body 240. The cleaning body holder 210 has a holding member 131. The holding member 131 has a single long structure extending in the longitudinal direction Y. The holding member 131 constitutes a tension applying unit 190. That is, one side (upper side in FIG. 13) in the thickness direction of the holding member 231 is the first tension applying portion 190A. Further, the holding member 231 has a convex portion on the other side (downward in FIG. 13) in the thickness direction. This convex portion is the second tension applying portion 190B.

The holding space 180 in the cleaning body 240 of the cleaning tool 200 is formed by joining both end portions of the holding space sheet 161 that is a single sheet-like member at the welding joint portion 176. Even with such a configuration, the first region 180A and the second region 180B of the holding space 180 according to the present invention can be configured.
The strip piece 162 a in the cleaning body 240 according to the present invention is formed by providing a plurality of cuts from one edge of the strip piece sheet 162. In addition, the strip piece sheet 162 is made into a pair, and the area | region where 162a is not formed in each strip piece sheet | seat and the predetermined position in the holding space sheet 161 are joined by a welding joining part.

  In a state where the cleaning body 240 is held by the cleaning body holder 210, the holding member 131 presses in the direction of expanding the inside of the holding space 180. That is, the first tension applying unit 190A of the holding member 131 presses the first region 180A of the holding space 180. Further, the second tension applying portion 190 </ b> B of the holding member 131 presses the second region 180 </ b> B of the holding space 180. As a result, tension is applied to the first region 180A and the second region 180B in the holding space 180.

Further, the second tension applying unit 190B is disposed on the inner side in the longitudinal crossing direction X than the first tension applying unit 190A.
Therefore, the second region 180B is inclined while being tensioned from the bottom to the top (from bottom to top in FIG. 13) from the second tension applying portion 190B to the first tension applying portion 190A (second elastic member 136). Is done. That is, the second region 180B forms a tension portion 191.

  As a result, the second region 180B is inclined in the direction in which the first region 180A is arranged (upward in FIG. 13). Furthermore, the strip piece 162a continuous with the second region 180B is also moved in the direction in which the first region 180A is arranged (upward in FIG. 13).

(Fourth modification)
Next, based on FIGS. 14-23, a 4th modification is demonstrated. The second elastic member 136 has a convex portion 237 and a convex portion 238. The convex portion 237 is provided on the distal end portion 133 side of the second elastic member 136. The convex portion 238 is provided on the base 132 side of the second elastic member 136.

The insertion direction Y1 is a direction in which the holding member 131 of the cleaning body holder 110 is inserted into the holding space 180 of the cleaning body 140. This insertion direction Y1 is the implementation structural example corresponding to the "insertion direction" in this invention.
The drawing direction Y2 is a direction in which the holding member 131 of the cleaning body holder 110 inserted into the holding space 180 of the cleaning body 140 is pulled out. This drawing direction Y2 is a direction facing the opposite direction to the insertion direction Y1. This drawing direction Y2 is an implementation configuration example corresponding to the “drawing direction” in the present invention.

  The convex portion 237 has an insertion side region 237A provided on the insertion direction Y1 side and a drawing side region 237C provided on the drawing direction Y2 side. Furthermore, the convex part 237 has an intermediate region 237B provided between the insertion side region 237A and the extraction side region 237C. The insertion side region 237A, the intermediate region 237B, and the extraction side region 237C are implementation configuration examples corresponding to the “insertion side region”, “intermediate region”, and “extraction side region” in the present invention.

Next, the structure of the convex part 237 will be described. For convenience, only the structure of the convex portion 237 on the distal end side 133 will be described, but the convex portion 238 on the base portion 132 side can have the same configuration as the convex portion 237.
FIG. 15 shows a state in which the cleaning body holder 110 is moved in the insertion direction Y <b> 1 and the holding member 131 of the cleaning body holder 110 is inserted into the holding space 180 of the cleaning body 140.
In this case, the insertion side region 237A of the convex portion 237 comes into contact with the joint portion 171A of the cleaning body 140. A point where the insertion side region 237A first comes into contact with the joint 171A is defined as an insertion start point 237A1. This insertion start point 237A1 is an implementation configuration example corresponding to the “insertion start point” in the present invention.

  Next, as shown in FIG. 16, the cleaning body holder 110 is further moved in the insertion direction Y1 until the insertion-side region 237A finally comes into contact with the joint portion 171A. The point where the insertion side region 237A finally comes into contact with the joint portion 171A is defined as an insertion end point 237A2. This insertion end point 237A2 is an implementation configuration example corresponding to the “insertion end point” in the present invention.

  Next, as shown in FIG. 17, the cleaning body holder 110 is further moved in the insertion direction Y1. Then, the joint portion 171A passes through the insertion end point 237A2 and comes into contact with the intermediate region 237B. Further, by moving the cleaning body holder 110 in the insertion direction Y1, the mounting of the cleaning body holder 110 and the cleaning body 140 is completed.

Here, as shown in FIG. 18, a straight line connecting the insertion start point 237A1 and the insertion end point 237A2 is defined as a first virtual straight line L1. A straight line parallel to the insertion direction Y1 passing through the insertion start point 237A1 is defined as a second virtual straight line L2. The angle formed by the first virtual line L1 and the second virtual line L2 is defined as a first angle A1.
The first virtual straight line L1, the second virtual straight line L2, and the first angle A1 correspond to the “first virtual straight line”, “second virtual straight line”, and “first angle” in the present invention. It is an implementation structural example.

FIG. 19 shows a state in which the cleaning body holder 110 is moved in the drawing direction Y2 from the state where the cleaning body holder 110 and the cleaning body 140 are mounted.
In this case, the drawing-side region 237C of the convex portion 237 comes into contact with the joint portion 171A of the cleaning body 140. A point where the drawing side region 237C first comes into contact with the joint portion 171A is a drawing start point 237C1. This drawing start point 237C1 is an implementation configuration example corresponding to the “drawing start point” in the present invention.

  Next, as shown in FIG. 20, the cleaning body holder 110 is further moved in the drawing direction Y <b> 2 until the drawing side region 237 </ b> C finally comes into contact with the joint portion 171 </ b> A. The point where the drawing side region 237C finally comes into contact with the joint portion 171A is defined as a drawing end point 237C2. This drawing end point 237C2 is an implementation configuration example corresponding to the “drawing end point” in the present invention.

  Next, as shown in FIG. 21, the cleaning body holder 110 is further moved in the drawing direction Y2. Then, the joint portion 171A passes through the drawing end point 237C2 and comes into contact with the intermediate region 237B. And the cleaning body holder 110 is removed from the cleaning body 140 by moving the cleaning body holder 110 further in the drawing direction Y2.

Here, as shown in FIG. 22, a straight line connecting the drawing start point 237C1 and the drawing end point 237C2 is defined as a third virtual straight line L3. A straight line parallel to the drawing direction Y2 passing through the drawing start point 237C1 is defined as a fourth virtual straight line L4. The angle formed by the third virtual straight line L3 and the fourth virtual straight line L4 is defined as a second angle A2.
The third virtual straight line L3, the fourth virtual straight line L4, and the second angle A2 correspond to “third virtual straight line”, “fourth virtual straight line”, and “second angle” in the present invention. It is an implementation structural example.

Here, as shown in FIG. 23, the first angle A1 is configured to be smaller than the second angle A2. This is an implementation configuration example of “the first angle is formed smaller than the second angle” in the present invention.
By configuring the convex portion 237 in this way, when the cleaning body holder 110 is mounted on the cleaning body 140, the operation can be performed smoothly. On the other hand, when the cleaning tool 100 is used, the cleaning body holder 110 and the cleaning body 140 are difficult to separate.

(5th modification)
Next, a fifth modification will be described based on FIGS. The cleaning body holder 330 of the cleaning body holder 310 according to the fifth modification is configured by a first elastic member 335 and a second elastic member 336. The second elastic member 336 includes a convex portion 337 on the distal end portion 333 side and a convex portion 338 on the base portion 332 side. The convex portion 337 on the distal end portion 333 side is formed by deforming the distal end portion 333 side of the second elastic member 336 outward.

That is, the convex portion 337 on the distal end portion 333 side of the cleaning body holder 310 according to the fifth modified example has a second elasticity compared to the convex portion 237 on the distal end portion 133 side of the cleaning body holder 110 according to the fourth modified example. The boundary between the member 336 and the convex portion 337 is not clear.
Further, with regard to the convex portion 337 having such a structure, there is a problem in particular where the insertion side region 337A of the convex portion 337 starts.

Therefore, how to obtain the “first angle” for the convex portion 337 having such a structure will be described with reference to FIG.
FIG. 25 shows a state in which the cleaning body holder 310 is moved in the insertion direction Y <b> 1 and the holding member 331 of the cleaning body holder 310 is inserted into the holding space 180 of the cleaning body 340.
In this case, the convex portion 337 comes into contact with the joint portion 171A of the cleaning body 340. A point where the insertion side region 237A first comes into contact with the joint portion 171A is defined as an insertion start point 337A1. A portion extending from the insertion start point 337A1 to the intermediate portion 337B is defined as an insertion side region 337A of the convex portion 337.
Thereby, even if it is a structure like the convex part 337, it becomes possible to fix insertion start point 337A1 and insertion end point similarly to the 5th modification example mentioned above. Therefore, the first angle can be determined also in the convex portion 337.

(Sixth Modification)
Next, a sixth modification will be described based on FIGS. 26 to 27, for convenience, only the structure of the second elastic member 436 and the convex portion 437 on the tip end side will be described.
As for the convex part 437, the insertion side area | region 437A and the extraction side area | region 437C are comprised by the straight line. Therefore, the intermediate region 437B has a dot shape.

FIG. 27 shows a state in which the cleaning body holder is moved in the insertion direction Y1, the holding member of the cleaning body holder is inserted into the holding space 180 of the cleaning body 140, and the cleaning body holder is moved in the pulling direction Y2. It is explanatory drawing which shows both the state which pulls out the holding member of a holder from the holding space 180 of the cleaning body 140. FIG.
In the case of the convex portion 437 having such a structure, the insertion end point 437A2 and the drawing end point 437C2 coincide with each other in the intermediate region 437B. On the other hand, even if the insertion end point 437A2 and the drawing end point 437C2 are the same portion in the convex portion 437, there is no problem in obtaining the “first angle” and the “second angle”.

(Seventh Modification)
Next, a seventh modification will be described based on FIGS. 28 to 29, only the structure of the second elastic member 536 and the convex portion 537 on the tip end side will be described for convenience.
The convex portion 537 has a concave portion 537AA in the insertion side region 537A.

FIG. 29 is an explanatory diagram illustrating a state in which the cleaning body holder is moved in the insertion direction Y <b> 1 and the holding member of the cleaning body holder is inserted into the holding space 180 of the cleaning body 140.
In the case of the convex portion 537, since the concave portion 537AA exists, the contact state between the insertion region 537A and the joint portion 171A is different from the convex portions according to the third to fifth modifications described above.
That is, the joining portion 171A passes through the recess 537AA from the insertion start point (not shown) of the insertion region 537A of the projection 537 to the insertion end point 537A1.
On the other hand, even if the insertion region 537A has the recess 537AA as described above, the insertion end point 537A2 is only the point where the insertion side region 537A comes into contact with the joint portion 171A last. This is the same even when the extraction side region 537C has a recess.
Therefore, even if the convex portion 537 has the concave portion 537AA, there is no problem in obtaining the “first angle” and the “second angle”.

  In the fourth to seventh modifications based on FIGS. 14 to 29, the description has been made focusing on the configuration of the convex portion on the tip end side. On the other hand, it is needless to say that the configuration of the convex portion on the distal end side described above can be appropriately implemented on the convex portion on the base side.

In the fourth to seventh modifications based on FIGS. 14 to 29, for convenience, only “joining portion 171 </ b> A” has been described as the joining portion of the cleaning body that comes into contact with the convex portion of the cleaning body holder. On the other hand, when obtaining 1st angle A1 and 2nd angle A2, it is needless to say that it can apply suitably also to the joint of various shapes and the joint of various arrangements.
At this time, for example, depending on the shape of the joint portion in the cleaning body, the arrangement form of the plurality of joint portions, and further the configuration of the intermediate portion of the cleaning body holder, each joint portion continuous in the longitudinal direction is The first angle A1 and the second angle A2 may be different angles.
Thus, when it has several 1st angle A1, let the smallest angle be a "1st angle" which concerns on this invention.
Furthermore, when it has several 2nd angle A2, let the largest angle be a "2nd angle" which concerns on this invention.

(Eighth modification)
Next, an eighth modification will be described with reference to FIGS. The cleaning body holder 610 includes a cleaning body holder longitudinal direction 610Y that is parallel to the insertion direction Y1, a cleaning body holder longitudinal crossing direction 610X that is a direction that intersects the cleaning body holder longitudinal direction 610Y, and a cleaning body holder longitudinal direction 610Y. And the cleaning body holder thickness direction 610Z that intersects both the cleaning body holder longitudinal crossing directions 610X. This cleaning body holder longitudinal direction 610Y is an example of the “holding tool longitudinal direction” according to the present invention. This cleaning body holder longitudinal crossing direction 610X is an example of the “holding tool longitudinal crossing direction” according to the present invention. This cleaning body holder thickness direction 610Z is an example of the “holding tool thickness direction” according to the present invention.

  The two holding members constitute a first holding member 6311 and a second holding member 6312, respectively. The first holding member 6311 is an example embodiment that corresponds to the “first long member” according to the present invention. The second holding member 6312 is an example embodiment that corresponds to the “second long member” according to the present invention. Each of the first holding member 6311 and the second holding member 6312 has two elastic members. Among the two elastic members in the first holding member 6311 and the two elastic members in the second holding member 6312, the elastic members arranged so as to be close to each other in the region of the intermediate portion between the base portion 632 and the tip portion 633 are One elastic member 635 is used. In addition, among the two elastic members in the first holding member 6311 and the two elastic members in the second holding member 6312, the elastic members arranged so as to be separated from each other in the region of the intermediate portion between the base portion 632 and the tip portion 633 are The second elastic member 636 is used.

The second elastic member 636 has a convex portion. That is, the convex portion 638 is provided on the base 632 side of the second elastic member 636. A convex portion 637 is provided on the distal end portion 633 side of the second elastic member 636.
The convex portion 637 on the tip end portion 633 side of the second elastic member 636 includes a convex portion separation region 637A extending in a direction in which the two second elastic members 636 are separated from each other, and the second elastic member 636 and the first elastic member. And a convex portion proximity region 637 </ b> B extending in a direction in which 635 is joined. This convex part separation area 637A is an example of the “convex part separation area” according to the present invention. This convex portion proximity region 637B is an example embodiment that corresponds to the “convex portion proximity region” according to the present invention.
The tip 633 is formed in a region where the second elastic member 636 and the first elastic member 635 are joined.

  In the cleaning tool (not shown) according to the eighth modification, the convex portion 637 is located in the vicinity of the tip portion 633. Therefore, the operation of mounting the cleaning body 140 on the holding member 631 by the user proceeds while the convex portion 637 positioned in the vicinity of the distal end portion 633 is in contact with the welding joint portions 171, 172, and 173. Therefore, the holding member 631 does not wobble in the holding space 180, and a stable mounting operation can be performed.

  In addition, the front-end | tip part 633 of the 1st holding member 6311 and the front-end | tip part 633 of the 2nd holding member 6312 are comprised in the direction which mutually faces. Therefore, the operation of mounting the cleaning body 140 on the holding member 631 by the user proceeds while the two distal end portions 633 sandwich the central welding wire 170 therebetween. Therefore, the holding member 631 does not wobble in the holding space 180, and a stable mounting operation can be performed. Further, in a state where the cleaning body 140 and the holding member 631 are mounted, the two distal end portions 633 may be configured to sandwich the center welding wire. In this case, it becomes difficult for the cleaning body 140 and the holding member 631 to separate from each other because the two distal end portions 633 sandwich the central welding wire.

FIG. 31 is a side view of cleaning body holder 610 in FIG. The second elastic member 636 is bent in a direction away from the first elastic member 635 in the cleaning body holder thickness direction 610Z. It can be said that the second elastic member 636 is bent upward. The region where the bending of the second elastic member 636 is started is a bending start region 636A. This bend start region 636A is an example of the “bend start region” according to the present invention.
The bending start region 636A is formed in a region where the convex portions 637 and 638 are provided in the second elastic member 636.

The bending start region 636A is easily subjected to pressure due to a load applied by the user, for example, during a cleaning operation by the user. On the other hand, the bending start region 636A is formed in the region of the second elastic member 636 where the convex portions 637 and 638 are formed. That is, the region where the convex portions 637 and 638 are formed is a region having the longest length in the cleaning body holder longitudinal cross direction 610X. Therefore, the bending start region 636A has a strong configuration. Therefore, the cleaning body holder 610 according to the eighth modification has a configuration that is not easily damaged.
In the eighth modified example, the bending start region 636A is provided on both the convex portion 637 and the convex portion 638. On the other hand, the bending start region 636A can be formed on either the convex portion 637 or the convex portion 638.

The base 632 has a region arranged in the holding space 180 in a state where the user wears the cleaning body 140 and the cleaning body holder 610. This region is referred to as a locking base region 632A. The longest length of the cleaning body holder thickness direction 610Z in the locking base region 632A is defined as a first length D1. On the other hand, the longest length in the cleaning body holder thickness direction 610Z at the tip 633 is defined as a second length D2.
The first length D1 is formed longer than the second length D2. As a result, when the user attaches the cleaning body 140 and the cleaning body holder 610, the distal end portion 633 can be smoothly inserted into the holding space 180. Furthermore, in a state where the cleaning body 140 and the cleaning body holder 610 are mounted, the locking base region 632A is more in contact with the configuration (the base sheet 151 and the holding sheet 160) forming the holding space 180. Can do. Therefore, the cleaning body 140 and the cleaning body holder 610 are difficult to separate.

By forming the first length D1 longer than the second length D2, in the holding member 631, the length of the cleaning body holder thickness direction 610Z in the pulling direction Y2 is the cleaning body holder thickness direction in the insertion direction Y1. It is formed longer than the length of 610Z.
That is, the length of the cleaning body holder thickness direction 610Z in the holding member 631 is configured to be shortened for a while as it goes from the drawing direction Y2 side to the insertion direction Y1 side. In other words, the holding member 631 is thinner in the region on the insertion direction Y1 side than in the region on the drawing direction Y2 side. Thereby, the holding member 631 can make the front end portion 633 side more flexible than the base portion 632. With this configuration, the user can easily place the cleaning body 140 on the distal end portion 633 side along the object to be cleaned. On the other hand, it is possible to ensure the strength with respect to the base 632 side.

In the distal end portion 633, the longest length in the cleaning body holder thickness direction 610Z in the region on the drawing direction Y2 side is defined as a third length D3. In the distal end portion 633, the longest length of the cleaning body holder thickness direction 610Z in the region on the insertion direction Y1 side is defined as a fourth length D4.
The third length D3 is formed longer than the fourth length D4. That is, the tip 633 has a tapered shape. As a result, when the user attaches the cleaning body 140 and the cleaning body holder 610, the distal end portion 633 can be smoothly inserted into the holding space 180.

32 is a cross-sectional view taken along line XI-XI in FIG. In the second elastic member 636, the longest length in the cleaning body holder longitudinal crossing direction 610X is defined as a length D5. In addition, when defining this length D5, the area | region in which the convex parts 637 and 638 in the 2nd elastic member 636 are not considered.
Moreover, in the 1st elastic member 635, let the longest length in the cleaning body holder longitudinal cross direction 610X be length D6.
The length D5 is formed longer than the length D6. As a result, the first elastic member 635 is less rigid than the second elastic member 636.

  That is, as shown in FIG. 33, when the user attaches the cleaning body 140 to the cleaning body holder 610, the first elastic member 635 bends more greatly than the second elastic member 636. That is, the second elastic member 636 has a smaller amount of bending change than the first elastic member 635. When the user attaches the cleaning body 140 to the cleaning body holder 610, the cleaning body 140 hangs down in a substantially arc shape due to its own weight. On the other hand, the second elastic member 636 which is the elastic member closest to the user also forms an arc shape. Therefore, when the cleaning body 140 is mounted on the cleaning body holder 610, the arc-shaped cleaning body 140 is mounted on the arc-shaped second elastic member 636. Therefore, the user can smoothly perform the mounting operation of the cleaning body 140 and the cleaning body holder 610. Further, the risk of damaging the cleaning body 140 can be reduced by the second elastic member 636.

  FIG. 34 shows a state in which the first elastic member 635 and the second elastic member 636 have moved in a direction to reduce the distance in the cleaning body holder thickness direction 610Z by the action of an external force. This is a situation that occurs, for example, when a user cleans a narrow gap with a cleaning tool. In such a state, an imaginary line connecting the first elastic member 635 and the second elastic member 636 is defined as an elastic member continuous imaginary line L5. This elastic member continuous virtual line L5 is an example embodiment that corresponds to the “elastic member continuous virtual line” according to the present invention. In this situation, the elastic member continuous virtual line L5 and the cleaning body holder longitudinal crossing direction 610X can be parallel to each other. Therefore, the user can smoothly clean a narrow gap.

In addition, it demonstrates per structure for making the elastic member continuous virtual line L5 and the cleaning body holder longitudinal cross direction 610X parallel by the effect | action of external force. First, the first elastic member 635 and the second elastic member 636 can be made flat. That is, in the cross-sectional shape of the 1st elastic member 635 and the 2nd elastic member 636, it shows that the length of the cleaning body holder longitudinal crossing direction 610X is a shape longer than the length of the cleaning body holder thickness direction 610Z.
Further, in the first elastic member 635, the rigidity of the region where the bending is started can be made lower than the rigidity of the region other than the region where the bending is started. This can be achieved by shortening the length of the cleaning body holder thickness direction 610Z in the region where the bending is started as compared with other regions.
Further, the rigidity of the bending start region 636A of the second elastic member 636 can be made lower than the rigidity of the region other than the bending start region 636A. This can be achieved by shortening the length in the cleaning body holder thickness direction 610Z in the bending start region 636A as compared with other regions.
In addition, the arc formed by bending the first elastic member 635 and the arc formed by bending the second elastic member 636 are arcs in a perfect circle.

Note that the elastic member continuous imaginary line L5 corresponds to the most protruding portion of the surface of the first elastic member 635 on the cleaning body holder thickness direction 610 and the surface of the second elastic member 635 on the cleaning body holder thickness direction 610. The most prominent portion is continuous.
Based on FIGS. 35 to 37, this “most protruding portion” will be described. 35 to 37, a holding member 631 is shown as a concept including both the first elastic member 635 and the second elastic member 636. 35 to 37 are sectional views of the holding member 631.
The holding member 631 shown in FIG. 35 has a flat surface on the cleaning body holder thickness direction 610Z. Therefore, the holding member 631 shown in FIG. 35 does not have the “most protruding portion”. In such a case, the imaginary line which continued each surface on the cleaning body holder thickness direction 610Z in the 1st elastic member 635 and the 2nd elastic member 636 forms the elastic member continuous virtual line L5.
The holding member 631 shown in FIG. 36 has a curved surface on the cleaning body holder thickness direction 610Z. In addition, the holding member 631 shown in FIG. 37 has an elliptical shape. In the holding member 631 shown in FIGS. 36 and 37, an imaginary line in which the tops of the first elastic member 635 and the second elastic member 636 on the cleaning body holder thickness direction 610Z are continuous is an elastic member continuous imaginary line. L5 is formed.
Note that the region where the elastic member continuous virtual line L5 is formed may be a partial region of the first elastic member 635 and the second elastic member 636.

(Ninth Modification)
Next, a ninth modification will be described based on FIGS. FIG. 38 is a plan view showing a main part of the cleaning body holder 710. 39 is a cross-sectional view taken along line XIII-XIII in FIG.
The cleaning body holder 710 according to the ninth modification is different in the configuration of the holding member from the cleaning body holder 610 according to the eighth modification. That is, the holding member 720 according to the ninth modified example has a region where the tip end portion 733 of the first holding member 7311 and the tip end portion 733 of the second holding member 7312 overlap with each other in the cleaning body holder longitudinal crossing direction 710X. ing. In other words, the tip portion 733 of the first holding member 7311 and the tip portion 733 of the second holding member 7312 have a region where they are stacked on each other in the cleaning body holder thickness 710Z.

  Therefore, the operation of mounting the cleaning body 140 on the holding member 731 by the user proceeds while the two distal end portions 733 reliably pinch the center welding wire 170. Therefore, the holding member 731 does not wobble in the holding space 180, and a stable mounting operation can be performed. Furthermore, in the state where the cleaning body 140 and the holding member 731 are mounted, the two tip portions 733 securely hold the center welding wire. Thus, the two distal end portions 733 sandwich the central welding wire, so that the cleaning body 140 and the holding member 731 are difficult to separate.

The present invention is not limited to the configurations of the above-described embodiments and the first to ninth modifications, and may be other configurations. For example, the cleaning body holder 110 has the two holding members 131 in a bifurcated shape, but may have only one holding member 131 without being formed in a bifurcated shape.
Moreover, it is also possible to combine suitably embodiment mentioned above and a 1st modification-a 9th modification.
