  Therefore, the present invention has been made in view of such a point, and in a cleaning body for cleaning an object to be cleaned, it is possible to take in an object to be collected such as dust, dust, dust or dirt to the back of the fiber. Therefore, it is an object to provide a technique effective for improving the cleaning effect.

  In order to achieve the above object, the invention described in each claim is configured. The invention described in each of these claims is for areas to be cleaned indoors, outdoors, and outdoors in detached houses, condominiums, buildings, factories, vehicles, etc. (floor surfaces, wall surfaces, windows, ceiling surfaces, outer wall surfaces, pillars, furniture surfaces, clothing , Curtains, blinds, bedding, lighting, electric cords, home appliances, etc.) and a cleaning tool for cleaning each component of the human body. These various cleaning regions may be configured as a flat surface, or may be configured as a curved surface, an uneven surface, or a step surface.

  The cleaning tool according to the present invention is used for cleaning a cleaning object, and includes a cleaning body holder and a cleaning body held by the cleaning body holder. In the present invention, the cleaning body is a disposable type that is intended for one-time use, or a multiple-time use while holding collection objects such as dust, dust, and dust collected from the object to be cleaned. It may be of a disposable type for replacement, or of a type that can be used repeatedly after washing.

  The cleaning body holder is configured to include a gripping portion, and a first holding body and a second holding body extending in a long shape in parallel from the gripping portion. The gripping unit is configured as a part that is gripped by a user's finger. Each holding body is configured as a portion that holds the cleaning body. At this time, the gripping part and the holding body may be configured so as to be inseparable from each other, or may be configured to be separable from each other. Moreover, what is necessary is just a structure provided with at least two holding bodies, and another holding body may be added.

  The cleaning body includes a first insertion space and a second insertion space, a first sheet and a second sheet, a first inner joint and a first outer joint, a second inner joint and a second It includes an outer joint, an intermediate region, a fibrous body, and a gap. Each of the first insertion space and the second insertion space is configured as an insertion space in which each of the first holding body and the second holding body of the cleaning body holder is inserted and extends along the first direction. . In addition to the first insertion space and the second insertion space, a further insertion space may be added. Here, the “insertion space extending along the first direction” is understood as an insertion space including an extending component along the first direction, and the insertion space includes all or one part of the insertion space. A configuration in which the extending direction of the part matches the first direction and a configuration in which the extending direction of all or part of the insertion space substantially matches the first direction are included. Both the first sheet and the second sheet are configured as a nonwoven fabric sheet made of a nonwoven fabric. A 1st inner side junction part and a 1st outer side junction part are comprised as a junction part which joins the piled 1st sheet | seat and 2nd sheet | seat, and divides 1st insertion space. A 2nd inner side junction part and a 2nd outer side junction part are comprised as a junction part which joins the piled 1st sheet | seat and 2nd sheet | seat, and divides 2nd insertion space. The intermediate region is configured as a region formed between the first inner joint portion and the second inner joint portion. The fibrous body is configured as a portion where a plurality of fibers extending in a second direction intersecting the first direction are joined to the first sheet in the intermediate region. The fibrous body may be configured to be joined to the first sheet by the first inner joining line or the second inner joining line existing in the intermediate region, or the first inner joining line or the second inner joining line may be used. The structure joined to a 1st sheet | seat by the junction part different from 2 inner side joining lines may be sufficient. In the state where each of the first holding body and the second holding body of the cleaning body holder is not inserted into the first insertion space and the second insertion space of the cleaning body, the expansion portion is the second in the intermediate region. The interval in the direction of is configured as a portion that exceeds the shortest interval among the intervals between the first holding body and the second holding body.

According to the cleaning tool having the above configuration, the first holding body and the second holding body of the cleaning body holder are inserted into the first insertion space and the second insertion space of the cleaning body, respectively. The insertion space and the second insertion space approach each other, whereby the fiber body in the intermediate region is in the direction in which the fiber body is disposed with respect to the first insertion space and the second insertion space, that is, the first The sheet and the fiber body are extruded in the overlapping direction. By this extrusion, the thickness of the fiber portions on both sides of the intermediate region of the fiber body (for example, the free end portion of the fiber body when the intermediate region is a fixed end portion) is increased. Therefore, the inter-fiber distance in the pushing direction of the fiber body is widened with respect to the cross section of the cleaning body, and the apparent specific volume can be increased as compared to before the cleaning body holder is attached to the cleaning body. As a result, it is possible to expand the area for collecting collection objects such as dust, dust, and dust to the inside of the fiber, making it possible to use the fiber body effectively, thereby improving the cleaning effect. It becomes possible to plan.
Further, the surface area increases as the interfiber distance of the fibrous body increases, and as a result, the cleaning range of one wipe increases and the wiping effect increases.
In addition, the above-mentioned state in which the specific volume and surface area of the fibrous body is increased is naturally formed by inserting each holding body into each insertion space, so that the fibers of the fibrous body are unwound by hand before use, By shaking the cleaning body holder together with the cleaning body, it is reasonable that the user does not have to perform an operation to increase the volume feeling of the cleaning body. And since the shape of the cleaning body once formed is forcibly maintained by each holding body inserted in each insertion hole, the said shape can be maintained stably longer.

  Moreover, in the cleaning tool of the further form which concerns on this invention, the fiber body of the said cleaning body is the structure joined to the 1st sheet | seat by the 1st inner side junction part and the 2nd inner side junction part in the intermediate | middle area | region. Preferably there is. According to such a configuration, the cleaning body is formed into the first sheet by using the first inner joint portion that divides the first insertion space and the second inner joint portion that divides the second insertion space. It is reasonable because it can be joined.

  Moreover, in the cleaning tool of the further form which concerns on this invention, the fiber body of the said cleaning body is along a 1st direction different from a 1st inner side junction part and a 2nd inner side junction part in an intermediate | middle area | region. It is preferable that the structure is joined to the first sheet by the intermediate joining portion that extends. Thereby, the cleaning body using the junction part different from a 1st inner side junction part and a 2nd inner side junction part is provided for joining of a fiber body and a 1st sheet | seat.

Moreover, in the cleaning tool of the further form which concerns on this invention, it is preferable that the fiber body of the said cleaning body is the structure containing the some fiber of a 1st group, and the some fiber of a 2nd group. The plurality of fibers of the first group are arranged on the first sheet side and are fibers bonded to the first sheet by at least the first inner joint portion and the second inner joint portion in the intermediate region. On the other hand, the plurality of fibers of the second group are arranged on the opposite side of the first sheet across the plurality of fibers of the first group, and the first inner joint portion and the second inner joint are disposed in the intermediate region. The fibers are bonded to the first sheet by an intermediate bonding portion extending along the first direction, which is different from the portion.
As a result, when the first insertion space and the second insertion space approach in accordance with the insertion operation of the cleaning body holder, the plurality of fibers of the first group swivel upwards on the cleaning body integrally with the first sheet. On the other hand, a cleaning body having a configuration in which the plurality of fibers of the second group do not rotate integrally with the first sheet above the cleaning body is realized.

  Moreover, in the cleaning tool of the further form which concerns on this invention, the fiber body of the said cleaning body is a 1st sheet | seat by the 1st outer junction part and the 2nd outer junction part in which the some fiber of a 1st group is further. It is preferable that it is the structure joined to. According to such a configuration, the plurality of fibers in the first group have more joints with the first sheet, and therefore have good followability when swiveling upward with the first sheet integrally with the first sheet.

  Moreover, in the cleaning tool of the further form which concerns on this invention, the said cleaning body has both the 1st insertion space and the 2nd insertion space in the direction where the some fiber of a fiber body cross | intersects a 1st direction. It is preferable that the configuration extends over the two. Thereby, the cleaning body in which the fiber body is not divided into the fiber corresponding to the first insertion space and the fiber corresponding to the second insertion space is realized.

  The cleaning body according to the present invention is configured substantially in the same manner as the cleaning body of each of the above cleaning tools. Therefore, according to the cleaning body according to the present invention, the same effect as the above-described effect can be obtained, and at least the collection target such as dust, dust, dust or dirt can be taken into the fiber. This makes it possible to improve the cleaning effect.

  Moreover, in the further form of the cleaning body which concerns on this invention, it is preferable that an intermediate | middle junction part is comprised as a junction part extended in zigzag form. Thereby, the shape of the intermediate joint is asymmetrical with respect to the first direction.

  Moreover, in the further form of the cleaning body which concerns on this invention, the space | interval of the 2nd direction between the insertion port of 1st insertion space and the insertion port of 2nd insertion space is reduced rather than an expansion part. It is preferable to have a structure having a narrowed portion. According to such a configuration, the expansion portion functions as a guide region for facilitating insertion of each holding body into each insertion space.

  Moreover, in the further form of the cleaning body which concerns on this invention, it is preferable that the surface opposite to a 1st sheet | seat is prescribed | regulated as a cleaning body surface of the said cleaning body among 2nd sheets. Thereby, the cleaning body having a configuration in which one side of the second sheet is exposed on the surface of the cleaning body, that is, a configuration in which another cleaning body element on one side of the second sheet is not joined is realized.

  As described above, according to the present invention, in a cleaning body for cleaning a cleaning target, it is possible to take in a target to be collected such as dust, dust, dust or dirt to the back of the fiber, thereby cleaning the object. It became possible to improve the effect.

The handle portion 150 is connected to the holder main body 140 via a connection portion 141 formed by one end portion of the handle main body 151 and one end portion of the holder main body 140. Regarding the connection structure of the handle part 150, the holder main body 140 and the handle part 150 (the handle main body 151 and the connection part 141) can be assembled as separate structures, or the holder main body 140 and the handle part 150 can be connected to each other. It is possible to appropriately adopt a configuration in which the connecting portion 141 is integrally molded with the connecting portion 141, or a configuration in which the connecting portion 141 is integrally molded with either the holder main body 140 or the handle main body 151. The handle portion 150 or the handle main body 151 here constitutes a “gripping portion” in the present invention.

  The holder main body 140 is a part having a function of holding the cleaning body 110 in a detachable manner. The holder main body 140 is provided with a pair of left and right long holding bodies 142 and 142. These holding bodies 142 and 142 have a fixed end 143 as an end on the connection portion 141 side and a free end 144 as an end on the opposite side in parallel (parallel to each other) at a predetermined interval. E) The elongated shape extends. That is, the holder main body 140 has a fork shape in which the tip side is divided into two forks by the holding bodies 142 and 142. Regarding the cross-sectional shapes of the holding plates 142, 142, those having a rectangular, square, circular, or polygonal cross section can be appropriately employed.

  Each holding body 142 is provided with a protruding piece 145 and a pressing plate 146. The protruding piece 145 protrudes from the outer edge portion 142a of each holding body 142 to the outside of the holding body. It is preferable that one or a plurality of the projecting pieces 145 be provided in the longitudinal direction of each holding body 142 (two in each holding body 142 in FIG. 1). Thereby, the site | part in which the protrusion piece 145 was provided among each holding body 142 is made into the widened part by which the length of the width direction was most expanded among each site | part of the said holding body. The holding plate 146 is configured as a plate-like member that extends forward between the two holding plates 142 and 142 and is curved so as to be convex toward the lower side. A locking projection (not shown) is provided. The holding bodies 142 and 142 here constitute the “holding body” in the present invention.

  Each holding body 142 can be inserted into a corresponding insertion space (an insertion hole 117 described later) formed in the cleaning body 110, and has a function of holding the cleaning body 110 in the insertion state in the insertion space. Have. In the inserted state, each holding body 142 is fitted in the insertion space of the cleaning body 110 so as to be in close contact with each other, and exerts a fixing action on the cleaning body 110. In addition, each holding body 142 has a protruding piece 145, which is a widened portion of the holding body, in the inserted state, acts as a stopper for the cleaning body 110. Further, in this inserted state, the presser plate 146 presses the cleaning body 110 from above, and the locking protrusion on the lower surface acts as a retaining member for the cleaning body 110. Thereby, in the insertion state of each holding body 142, the cleaning body 110 is reliably held while being prevented from being detached by the holder main body 140.

  In addition, it is preferable to appropriately set the shape of each holding body 142 in order to facilitate the insertion operation of each holding body 142. For example, regarding the shape of the holding body in the plate width direction, a configuration in which the plate width of each holding body 142 is constant between the fixed end 143 and the free end 144, or the plate width of each holding body 142 is set to the free end 144. It is possible to employ a configuration that becomes smaller as it goes. Further, for example, regarding the shape of the holding body in the plate thickness direction, a configuration in which the plate thickness of each holding body 142 is constant between the fixed end 143 and the free end 144, or the plate thickness of each holding body 142 is the free end. A configuration that becomes smaller toward 144 can be employed.

The cross-sectional structure regarding the BB line of the cleaning body 110 in FIG. 3 is shown.

  As shown in FIG. 2, the cleaning body 110 of the present embodiment includes a sheet-like holding sheet portion 111 and a brush portion 114 as its constituent elements. The brush portion 114 is overlapped on one surface of the holding sheet portion 111, and these components are joined at a predetermined joining portion.

  As shown in FIG. 4, the holding sheet portion 111 is formed by stacking a sheet-like first sheet 112 and a second sheet 113 each made of a nonwoven fabric. The holding sheet portion 111 is preferably configured such that the long side of the second sheet 113 in the first direction 10 is shorter than the long side of the first sheet 112 in the first direction 10. Thereby, in the state where the first sheet 112 and the second sheet 113 are overlapped, the extended surface of the first sheet 112 that extends from the second sheet 113 inserts the holding body 142 of the cleaning body holder 130, which will be described later. The function of smoothly guiding to the hole 117 is achieved. The first sheet 112 and the second sheet 113 here correspond to the “first sheet” and the “second sheet” in the present invention, respectively.

  On the other hand, the brush portion 114 is formed by stacking the fiber assembly 115 and the sheet-like third sheet 116 made of a nonwoven fabric, and is attached to the second sheet 113 of the holding sheet portion 111 on the fiber assembly 115 side. . Therefore, the cleaning body 110 is configured such that the fiber assembly 115 is sandwiched between the second sheet 113 and the third sheet 116 of the holding sheet portion 111. The fiber assembly 115 is composed of three stacked fiber bodies. Of these three fibrous bodies, one fibrous body 115a on the second sheet 113 side is a fibrous body composed of a plurality of fibers of the first group (corresponding to “a plurality of fibers of the first group” in the present invention). The other two fiber bodies 115b are made of a plurality of fibers of the second group (corresponding to “a plurality of fibers of the second group” in the present invention). Each of the fiber bodies 115a and 115b constituting the fiber assembly 115 is configured such that a plurality of fibers extend in the second direction 12 across both the one insertion hole and the other insertion hole. Thereby, the cleaning body in which the fiber assembly 115 is not divided into the fiber corresponding to the one insertion hole 117 and the fiber corresponding to the other insertion hole 117 is realized. In the cleaning body 110, one cleaning body surface (cleaning body upper surface) is formed by the second sheet 113 of the holding sheet portion 111, and the other cleaning body surface (cleaning body) is formed by the third sheet 116 of the brush portion 114. Bottom surface) is formed. Thereby, as for the cleaning body 110, the single side | surface of the 2nd sheet | seat 113 is exposed to the cleaning body surface, while the single side | surface of the 3rd sheet | seat 116 is exposed to the cleaning body surface.

  The first sheet 112, the second sheet 113, and the third sheet 116 having the above-described configuration are each a plurality of strip pieces (strip portions) that are cut in a zigzag shape at the ends in the direction of arrow 12 in FIG. 112a, 113a and 116a are preferably provided. All of these strips 112a, 113a, and 116a are configured to extend in a long shape in the direction of arrow 12 in FIG. In this case, the sheets 112, 113, and 116 including the strip pieces are also referred to as strip sheets. The strip having such a configuration is particularly effective as a structure having a high cleaning function that easily catches and captures dust and easily draws dust that has entered the recess. In addition, regarding the shape of the strips 112a, 113a, and 116a, a single type or a plurality of types of shapes such as a zigzag shape, a linear shape, and a curved shape can be appropriately used.

(Configuration of nonwoven fabric)
As for the first sheet 112, the second sheet 113, and the third sheet 116 having the above-described configuration, a sheet-like nonwoven fabric typically made of hot-melt fibers (thermoplastic fibers) can be used. Accordingly, the first sheet 112, the second sheet 113, and the third sheet 116 are also referred to as “nonwoven fabric sheets”. This non-woven fabric is a sheet-like composition made by fixing or intertwining fibers by mechanical, chemical, or thermal treatment, and can be joined by partially including thermoplastic fibers. And configured as a nonwoven fabric having a plurality of strips. As the thermoplastic fiber (hot melt fiber), polyethylene, polypropylene, polyethylene terephthalate, or the like can be used.

Moreover, it is preferable that this nonwoven fabric is comprised with a 10-100 g / m < ² > thermoplastic fiber provided with practical intensity | strength. As this non-woven fabric, those manufactured by air-through method, spun bond method, thermal bond method, spun lace method, point bond method, melt blow method, stitch bond method, chemical bond method, needle punch method, etc. should be used appropriately. Can do. The nonwoven fabric referred to here corresponds to the “nonwoven fabric” in the present invention. In addition, in order to improve the sweeping-out function at the time of cleaning, it is preferable to use a highly rigid nonwoven fabric. Instead of or in addition to the non-woven fabric, a material obtained by processing a material such as urethane, sponge, woven fabric, net, or walif into a strip shape may be used.

(Configuration of fiber assembly)
On the other hand, each of the fiber bodies 115a and 115b of the fiber assembly 115 is a single fiber structure made of fibers, or a fiber structure in which fibers are aligned in the length direction and / or radial direction (twisted yarn, spun yarn, a plurality of A thread material in which long fibers are partially connected), or an aggregate of the fiber structure, and is configured as a fiber body that includes thermoplastic fibers in part and can be joined. The fiber forming each fibrous body is a structural unit such as a thread or a woven fabric, and is defined as a thin and flexible form having a sufficient length compared to the thickness, and typically a long continuous The shaped fibers are long fibers (filaments), and the short fibers are short fibers (staples). Similar to the strips 112a, 113a, and 116a, the fibers of the fibrous body are configured to extend in a long shape in the direction of the arrow 12 in FIG. The fiber assembly 115 is also referred to as a “fiber bundle” in which a plurality of fibers are formed in a bundle shape. The “fiber body” in the present invention is configured by the fiber bodies 115 a and 115 b constituting the fiber assembly 115.

  In the present embodiment, the case where the fiber assemblies 115a and 115b are overlapped to form the fiber assembly 115 is described, but the number of fiber bodies can be one or more as necessary. . The fiber assembly 115 and the fiber bodies 115a and 115b preferably have a planar structure with a predetermined plane or curved surface, and are configured as a three-dimensional shape having a certain thickness or a thin sheet shape. The “fiber body” here is typically a length obtained by opening a tow from a material made of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon, rayon, or the like. An aggregate of fibers (filaments) is frequently used as this fiber body. In particular, the core portion is preferably polypropylene (PP) or polyethylene terephthalate (PET), and the sheath portion covering the outer surface of the core portion is preferably composed of a composite fiber of polyethylene (PE). The long fibers forming this fiber body preferably have a fineness of 0.5 to 66 dtex. Moreover, each fiber body may be comprised from the fiber of the almost same fineness, or the structure in which each fiber body contains the fiber of a different fineness may be sufficient. Moreover, when using the fiber containing a thermoplastic resin, it is preferable to use at least 2 or more types of resin of different melting | fusing point (For example, resin whose melting | fusing point difference is 20 degreeC or more).

  Moreover, in order to improve the sweeping-out function at the time of cleaning, it is preferable to use a fiber body including a highly rigid fiber, that is, a fiber having a high fineness. Moreover, it is preferable that this fiber body is set as the structure which has a crimped fiber. In this case, it is preferable to use crimped fibers having 5 to 30 crimps per inch. A crimped fiber here is comprised as a fiber to which the predetermined winding shrinkage process was provided, and is set as the structure where fibers are easy to get entangled. When such a crimped fiber is used, the fiber body becomes bulkier than the state before the cleaning body holder is mounted, and further, a structure in which dust is easily taken into the crimped portion is obtained. This structure can be realized in particular by using crimped fibers formed from tow fibers. Moreover, it is preferable to use a fiber containing a dusting oil agent in order to reliably adsorb dust, dust, dust and the like.

  As a fibrous body, a flat yarn obtained by slitting a film into a tape shape and extending in the longitudinal direction, or a thermoplastic film resin called a split yarn, is scraped in a direction perpendicular to the orientation direction of the resin to become a fibrous shape. You may use what the film was joined by mesh shape. Alternatively, a bulky and low fiber density nonwoven fabric such as an air-through nonwoven fabric may be used as the fibrous body.

It can be configured as an insertion space. The “first insertion space” and the “second insertion space” in the present invention are configured by the insertion holes 117 and 117 referred to here.

  FIG. 5 is referred to regarding a specific joining portion of the cleaning body 110 joined by the first joining portion 121, the second joining portion 122, and the third joining portion 123. As shown in FIG. 5, both the first joining portion 121 and the second joining portion 122 are fibrous bodies on the holding sheet portion 111 and part of the brush portion 114, specifically, the first sheet 112 and the second sheet 113. It is comprised as a junction part which joins three components which added 115a. Thereby, only the fiber body 115a composed of a plurality of fibers of the first group among the fiber bodies of the fiber assembly 115 is connected to the holding sheet portion 111 at the first joint portion 121 and the second joint portion 122, and the second group. The fibrous body 115 b made of a plurality of fibers is not connected to the holding sheet portion 111 at the first joint portion 121 and the second joint portion 122. On the other hand, the third joining portion 123 is configured as a joining portion that joins all of the holding sheet portion 111 and the brush portion 114.

  According to such joining, the holding sheet portion 111 (the first sheet 112 and the second sheet 113) and the fiber body 115a are both fixed ends at the ends joined by the first outer joining portion 121a. A first extending portion 111a extending with the end opposite to the first inner bonding portion 121b as a free end across the first outer bonding portion 121a, and an end bonded by the second outer bonding portion 122a The second extending portion 111b extends with the end portion on the opposite side of the second inner joint portion 122b sandwiching the second outer joint portion 122a as a free end. On the other hand, the portion excluding the fibrous body 115a in the brush portion 114, that is, the portion composed of the fibrous body 115b and the third sheet 116 has the end joined at the third joining portion 123 as a fixed end, and the third joining portion. 123, a first extending portion 114a and a second extending portion 114b each extending with the end portion on the side away from 123 as a free end.

  Further, in the cleaning body 110 of the present embodiment, when the cleaning body holder 130 is not attached, that is, when each holding body 142 is not completely inserted into each insertion hole 117, A feature is that the distance d1 in the direction 12 includes the widening portion 124 that exceeds the shortest distance among the distances d2 between the two holding bodies 142 and 142. The spacing part 124 may be formed over the entire region of the cleaning body 110 in the first direction 10, or may be formed in a part of the cleaning body 110 in the first direction 10. FIG. 3 shows an embodiment in which the distance d <b> 2 between the two holding bodies 142, 142 is constant in the first direction 10. Further, on both sides of the widening portion 124 with respect to the first direction 10, the distance between the two insertion holes 117, 117 in the second direction 12 is narrower than the widening portion 124, specifically, the distance d 1 is set. Spacing portions 125, 125 that are less than the distance d2 are provided. In particular, the separation portion 125 on the insertion port 117a side functions as a guide region for facilitating insertion of each holding body 142 into each insertion hole 117. The expanded portion 124 and the reduced portion 125 here correspond to the “expanded portion” and the “reduced portion” in the present invention.

  In addition to FIG. 3, FIG. 6 is referred further about the effect of the cleaning body 110 which has the expansion part 124 of the said structure. 6 shows a state before and after each holding body 142 is inserted into each insertion hole 117 with respect to the cross-sectional structure of the cleaning body 110 in FIG.

  In FIG. 3, when each holding body 142 is inserted into each insertion hole 117, first, the free end 144 of one holding body 142 comes into contact with the inclined region 121f on the insertion port 117a side of the first inner joint portion 121b, In addition, the free end 144 of the other holding body 142 contacts the inclined region 122f on the insertion port 117a side of the second inner joint portion 122b. When the insertion of the holding body 142 is continued, the inclined areas 121f and 122f operate so as to be attracted to each other by the holding bodies 142 and 142, and further, the straight line area 121e in the middle connected to the inclined areas 121f and 122f. , 122e also operate so as to be attracted to each other by the two holding bodies 142, 142.

  As a result, as shown in FIG. 6, the two insertion holes 117, 117 approach the directions of arrows 14 and 16 in the drawing, whereby the holding sheet portion 111 and the fiber body 115 a in the intermediate region 118 are inserted into the insertion hole 117. , 117 are pushed in the direction in which the fiber assembly 115 is arranged, that is, in the direction of the arrow 18 in the drawing. This extrusion operation increases the thickness of the fiber portions of the fiber assembly 115 on both sides of the intermediate region 118 (for example, the free end portion of the fiber assembly 115 when the intermediate region 118 is a fixed end). Specifically, the holding sheet portion 111 and the first extending portion 111a of the fibrous body 115a have their free ends pivoted in the direction of the arrow 20 around the intermediate region 118 with the third joint 123 as the pivot center, The holding sheet portion 111 and the second extending portion 111b of the fibrous body 115a have their free ends pivoted in the direction of the arrow 22 around the intermediate region 118 with the third joint 123 as the pivot center. Further, when the projecting piece 145 of each holding body 142 slides on the first outer joint portion 121a or the second outer joint portion 122a, the swiveling operation of the first extending portion 111a and the second extending portion 111b. Is further encouraged. In order to perform such a turning operation more reliably, regarding the cross section of the cleaning body 110 in the width direction (second direction in FIG. 3), the shape of the components above the holding sheet portion 111 and the shape thereof It is preferable that the shape of the lower component is asymmetric. In the case of the embodiment shown in FIG. 6, the cleaning body 110 is asymmetric because no component is provided above the holding sheet portion 111.

  On the other hand, in the turning operation of the first extending portion 111a and the second extending portion 111b, the first extending portion 114a of the third sheet 116 and the fibrous body 115b, and the first extending portion of the third sheet 116 and the fibrous body 115b. 2 The extended portions 114b are in a state where their positions are substantially maintained, or due to the self-weight action of each fibrous body, the free end portion of the fibrous body is around the intermediate region 118 with the third joint 123 as the pivot center. Turn in the direction of arrow 24 or 26.

The swivel movement of the first extending portion 111a and the second extending portion 111b causes the interfiber distance in the extrusion direction of the fiber assembly 115 with respect to the cross section of the cleaning body 110 in the width direction (arrow 12 direction in FIG. 3). Since it is spread, it is possible to increase the apparent specific volume compared to before the cleaning body holder 130 is attached to the cleaning body 110. As a result, the area for collecting collection objects such as dust, dust, and dust can be extended to the inside of the fiber, and the fiber assembly 115 can be used effectively, thereby providing a cleaning effect. It is possible to improve.
Further, the surface area increases as the inter-fiber distance of the fiber assembly 115 increases, and as a result, the cleaning range of one wipe increases and the wiping effect increases.
In addition, the above-described state in which the specific volume and the surface area of the fiber assembly 115 are increased is naturally formed by inserting each holding body 142 into each insertion hole 117. Therefore, the fibers of the fiber assembly 115 are used before use. It is reasonable that the user does not have to perform an operation to increase the volume feeling of the cleaning body 110 by unraveling by hand or shaking the cleaning body holder 130 together with the cleaning body 110. In addition, since the shape of the cleaning body 110 once formed is forcibly maintained by each holding body 142 inserted into each insertion hole 117, the shape can be stably maintained for a longer time.
