The joining part 122 is joined to the base part 132 of the cleaning body holding part 130. The handle 121 is formed in a long shape extending from the joint portion 122. This handle portion 120 is an implementation configuration example corresponding to the “gripping portion” in the present invention. For convenience of explanation, the upper side and the lower side in FIG. 2 are referred to as the right side and the left side of the cleaning body holder 110.
　清掃体保持部１３０は、樹脂材料にて成型されており、清掃シート１４０を保持するための部材である。清掃体保持部１３０は、長尺状に形成された２つの保持部材１３１、凸部１３７、１３８および押え板１３９等を主体として構成されている。
　具体的には、清掃体保持部２２０は、ポリプロピレン（ＰＰ）が使用されている。なお、清掃体保持部２２０は可撓性を有する樹脂材料を適宜選択することができる。例えば、ポリエチレン（ＰＥ）、ポリエチレンテレフタラート（ＰＥＴ）、アクリロニトリル－ブタジエン－スチレン樹脂（ＡＢＳ）、ポリエステル系の熱可塑性エラストマーを使用できる。
この清掃体保持部１３０が、本発明における「保持部」に対応する実施構成例である。この凸部１３７、１３８が、本発明における「凸部」に対応する実施構成例である。 The cleaning body holding part 130 is a member that is molded of a resin material and holds the cleaning sheet 140. The cleaning body holding part 130 is mainly composed of two holding members 131 formed in a long shape, convex parts 137 and 138, a pressing plate 139, and the like.
Specifically, the cleaning body holder 220 is made of polypropylene (PP). In addition, the cleaning body holding | maintenance part 220 can select the resin material which has flexibility suitably. For example, polyethylene (PE), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene resin (ABS), and polyester-based thermoplastic elastomer can be used.
This cleaning body holding | maintenance part 130 is the implementation structural example corresponding to the "holding | maintenance part" in this invention. The convex portions 137 and 138 are an implementation configuration example corresponding to the “convex portion” in the present invention.
　保持部材１３１は、基部１３２からハンドル１２１が延在する方向と反対の方向に向かって延在して形成されている。すなわち、保持部材１３１は、基部１３２と先端部１３３を有し、基部１３２から先端部１３３に向かって延在した中間部１３４が形成されている。２つの保持部材１３１の先端部１３３はそれぞれ自由端となっている。
　この基部１３２、先端部１３３、中間部１３４が、本発明における「連接部」、「先端部」、「延在部」に対応する実施構成例である。 The holding member 131 is formed to extend from the base portion 132 in a direction opposite to the direction in which the handle 121 extends. That is, the holding member 131 has a base portion 132 and a distal end portion 133, and an intermediate portion 134 that extends from the base portion 132 toward the distal end portion 133 is formed. The front end portions 133 of the two holding members 131 are free ends.
The base portion 132, the tip portion 133, and the intermediate portion 134 are implementation configuration examples corresponding to the “joining portion”, “tip portion”, and “extending portion” in the present invention.
　中間部１３４は、基部１３２および先端部１３３に対し、外側方向Ｄ１へ突出している。よって、保持部材１３１は中間部１３４が外側方向Ｄ１へ突出する湾曲形状とされる。
　なお、凸部１３７、１３８において、保持部材１３１における先端部１３３側に設けられた凸部１３７を第１凸部１３７とする。また、保持部材１３１における基部１３２側に設けられた凸部１３８を第２凸部１３８とする。
　この第１凸部１３７、第２凸部１３８が、本発明における「第１凸部」、「第２凸部」の実施構成例である。 The intermediate portion 134 projects in the outer direction D1 with respect to the base portion 132 and the distal end portion 133. Therefore, the holding member 131 has a curved shape in which the intermediate portion 134 protrudes in the outer direction D1.
In the convex portions 137 and 138, the convex portion 137 provided on the distal end portion 133 side of the holding member 131 is referred to as a first convex portion 137. Further, the convex portion 138 provided on the base 132 side of the holding member 131 is referred to as a second convex portion 138.
This 1st convex part 137 and the 2nd convex part 138 are the implementation structural examples of the "1st convex part" and the "2nd convex part" in this invention.
　押え板１３９は、基部１３２から突出して形成されている。押え板１３９は、一対の保持部材１３１の間に、保持部材１３１と平行に延在するように形成されている。押え板１３９は、下方に向けて凸形状となるように湾曲して形成される板状部材として構成され、更に下面に係止突部（図示省略）を備えている。 The holding plate 139 is formed so as to protrude from the base portion 132. The holding plate 139 is formed between the pair of holding members 131 so as to extend in parallel with the holding member 131. The presser plate 139 is configured as a plate-like member that is curved so as to be convex downward, and further includes a locking projection (not shown) on the lower surface.
　図３に示すように、保持部材１３１の長手交差方向Ｘにおける外側方向Ｄに最も突出した部分は、第１最外部１３４Ｘとされる。なお、第１最外部１３４Ｘは、保持部材１３１の中間部１３４に形成される。さらに、第１最外部１３４Ｘは、中間部１３４における長手方向Ｙの長さを２分した位置に設けられている。これにより、中間部１３４は、第１最外部１３４Ｘを極大値とする曲線状に形成される。
　そして、第１凸部１３７の長手交差方向Ｘにおける外側方向Ｄ１に最も突出した部分は、第２最外部１３７Ｘとされる。
　この第１最外部１３４Ｘが、本発明における「最外部」の実施構成例である。 As shown in FIG. 3, the portion of the holding member 131 that protrudes most in the outer direction D in the longitudinal cross direction X is the first outermost portion 134X. The first outermost part 134X is formed in the intermediate part 134 of the holding member 131. Furthermore, the first outermost part 134X is provided at a position obtained by dividing the length of the intermediate part 134 in the longitudinal direction Y by two. Thereby, the intermediate part 134 is formed in the curve shape which makes the 1st outermost part 134X the maximum value.
The portion of the first convex portion 137 that protrudes most in the outer direction D1 in the longitudinal cross direction X is the second outermost portion 137X.
The first outermost part 134X is an example of the “outermost part” in the present invention.
　長手方向中心線ＹＣＬと第１最外部１３４Ｘとを結ぶ最短直線は、第１最外仮想直線Ｘ１とされる。
　長手方向中心線ＹＣＬと第２最外部１３７Ｘとを結ぶ最短直線は、第２最外仮想直線Ｘ２とされる。
　この第１最外仮想直線Ｘ１、第２最外仮想直線Ｘ２が、本発明における「第１最外仮想直線」、「第２最外仮想直線」の実施構成例である。
　第１最外仮想直線Ｘ１は、第２最外仮想直線Ｘ２よりも長く形成されている。この構成により後述する作用を奏する。 The shortest straight line connecting the longitudinal center line YCL and the first outermost part 134X is the first outermost virtual straight line X1.
The shortest straight line connecting the longitudinal center line YCL and the second outermost 137X is the second outermost virtual straight line X2.
The first outermost virtual straight line X1 and the second outermost virtual straight line X2 are implementation configuration examples of the “first outermost virtual straight line” and the “second outermost virtual straight line” in the present invention.
The first outermost virtual straight line X1 is formed longer than the second outermost virtual straight line X2. With this configuration, the effects described later are exhibited.
（清掃体の構成）
　次に図４～図７を参照しつつ、清掃体１４０について説明する。清掃体１４０は、拭き清掃において清掃対象である被清掃面上の汚れを掻き取る汚れ掻き取り機能を有するシート状の清掃体である。図５、図６に示すように、清掃体１４０は、平面視で長方形状に形成されている。清掃体１４０の長辺方向は、繊維集合体を構成する複数の繊維が延在する延在方向が交差する方向と概ね合致する。 (Configuration of cleaning body)
Next, the cleaning body 140 will be described with reference to FIGS. The cleaning body 140 is a sheet-like cleaning body having a dirt scraping function for scraping off dirt on a surface to be cleaned which is a cleaning target in wiping cleaning. As shown in FIGS. 5 and 6, the cleaning body 140 is formed in a rectangular shape in plan view. The long side direction of the cleaning body 140 substantially matches the direction in which the extending directions in which the plurality of fibers constituting the fiber assembly extend intersect.
　図４に示すように、清掃体１４０は、清掃体本体１５０と保持シート１６０を主体として構成されている。この清掃体１４０は、一回使用を目安とした使い捨てタイプのものや、清掃対象の被清掃面から除去したごみや埃を保持しつつ複数回の使用を目安として交換を行う使い捨てタイプのものであってもよいし、或いは洗濯などを行ったうえで繰り返し使用することが可能なタイプのものであってもよい。 As shown in FIG. 4, the cleaning body 140 is mainly composed of a cleaning body main body 150 and a holding sheet 160. This cleaning body 140 is a disposable type that is used once as a guide, or a disposable type that is exchanged using multiple times as a guide while holding dust and dust removed from the surface to be cleaned. It may be of a type that can be used repeatedly after washing or the like.
　清掃体本体１５０は、いずれもシート状の基材シート１５１、繊維集合体１５２、清掃対象側シート１５３が積層されて接合されている。これら基材シート１５１、繊維集合体１５２、清掃対象側シート１５３は、平面視が同様の長方形とされ、いずれも清掃体１４０の長辺方向に長尺状に延在している。繊維集合体１５２及び清掃対象側シート１５３は、汚れ掻き取り機能を有する刷毛状部位を構成しており、いわゆる「刷毛部」とも称呼される。 The cleaning body body 150 is formed by laminating and joining a sheet-like base material sheet 151, a fiber assembly 152, and a cleaning target side sheet 153. The base sheet 151, the fiber assembly 152, and the cleaning target side sheet 153 have the same rectangular shape in plan view, and all extend in a long shape in the long side direction of the cleaning body 140. The fiber assembly 152 and the cleaning target side sheet 153 constitute a brush-like portion having a dirt scraping function, and are also referred to as a so-called “brush portion”.
　図４に示すように、基材シート１５１および清掃対象側シート１５３は、長方形状の不織布で形成されたシートである。基材シート１５１は、清掃体１４０の短辺方向に複数のジグザグ状の短冊片１５１ａが並列状に延在している。また、清掃対象側シート１５３は、清掃体１４０の短辺方向に複数のジグザグ状の短冊片１５３ａが並列状に延在している。短冊片１５３ａは、短冊片１５１ａよりも幅が狭く構成されており、曲げ剛性が低くなっている。 As shown in FIG. 4, the base sheet 151 and the cleaning target side sheet 153 are sheets formed of a rectangular nonwoven fabric. In the base sheet 151, a plurality of zigzag strips 151 a extend in parallel in the short side direction of the cleaning body 140. The cleaning target side sheet 153 has a plurality of zigzag strips 153 a extending in parallel in the short side direction of the cleaning body 140. The strip piece 153a is configured to be narrower than the strip piece 151a and has low bending rigidity.
　図４に示すように、繊維集合体１５２は、繊維による単一の繊維構造体や、繊維が長さ方向および／または径方向にそろった繊維構造体（撚糸、紡績糸、複数の長繊維が部分的に接続された糸材など）、ないし当該繊維構造体の集合体とされ、熱可塑性繊維を一部に含み融着（「溶着」ともいう）が可能な繊維集合体として構成されている。繊維集合体１５２を形成する繊維は、糸、織物などの構成単位であり、太さに比して十分な長さを持つ、細くてたわみやすい形態のものである。典型的には長い連続状の繊維が長繊維（フィラメント）とされ、短い繊維が短繊維（ステープル）とされる。 As shown in FIG. 4, the fiber assembly 152 includes 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, and a plurality of long fibers. Partly connected thread material or the like) or an aggregate of the fiber structure, and is configured as a fiber aggregate that includes thermoplastic fibers in part and can be fused (also referred to as “welding”). . The fiber forming the fiber assembly 152 is a structural unit such as a thread or a woven fabric, and has a thin and flexible shape having a sufficient length compared to the thickness. Typically, long continuous fibers are long fibers (filaments), and short fibers are short fibers (staples).
　この繊維集合体１５２の繊維は、基端側が中央溶着線１７０、溶着接合部１７１、１７２、１７３にて接合されるとともに、当該溶着接合部を固定端とし当該固定端と対向する側（先端側）を自由端として、清掃体１４０（或いは繊維集合体１５２）の短辺方向に長尺状に延在する構成とされる。この繊維集合体１５２は、複数の繊維が束状に形成された「繊維束」とも称呼される。なお、この溶着接合部１７１、１７２、１７３は、後述する通り保持空間１８０を形成する。
　この溶着接合部１７１、１７２、１７３が本発明における「接合部」に対応する実施構成例である。 The fibers of this fiber assembly 152 are joined at the proximal end side by the central welding wire 170 and the welded joints 171, 172, and 173, and the side facing the fixed end (front end side) using the welded joint as a fixed end ) As a free end, and the cleaning body 140 (or the fiber assembly 152) extends in the long side direction. The fiber assembly 152 is also referred to as a “fiber bundle” in which a plurality of fibers are formed in a bundle shape. The weld joints 171, 172, 173 form a holding space 180 as will be described later.
These welded joints 171, 172, and 173 are implementation configuration examples corresponding to “joints” in the present invention.
　なお、繊維集合体１５２は、三つの繊維層が積層して形成されているが、繊維層の数は必要に応じて１または複数とすることができる。この繊維集合体１５２は、所定の平面や曲面による面構造を有するとともに、ある程度の厚みを有する立体形状として、或いは薄肉シート形状として構成されるのが好ましい。繊維集合体１５２は、典型的にはポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）、ポリエチレンテレフタレート（ＰＥＴ）、ナイロン、レーヨンなどを材質とし、実用上はトウを開繊することによって得られる長繊維（フィラメント）の集合体が用いられることが好ましい。特には、芯部分がポリプロピレン（ＰＰ）或いはポリエチレンテレフタレート（ＰＥＴ）であり、この芯部分の外面を覆う鞘部分がポリエチレン（ＰＥ）の複合繊維を用いて繊維集合体が構成されるのが好ましい。また、この繊維集合体１５２を形成する長繊維の繊度は、１～５０ｄｔｅｘのものが好ましく、更には２～１０ｄｔｅｘのものが好ましい。また、各繊維集合体は概ね同様の繊度の繊維から構成されてもよいし、或いは各繊維集合体が異なる繊度の繊維を含む構成であってもよい。 In addition, although the fiber assembly 152 is formed by laminating three fiber layers, the number of fiber layers can be one or more as necessary. The fiber assembly 152 preferably has a planar structure with a predetermined plane or curved surface, and is configured as a three-dimensional shape having a certain thickness or a thin sheet shape. The fiber assembly 152 is typically made of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon, rayon, etc., and is practically a long fiber (filament) obtained by opening the tow. ) Is preferably used. In particular, it is preferable that the core portion is made of polypropylene (PP) or polyethylene terephthalate (PET), and the sheath portion covering the outer surface of the core portion is made of a composite fiber of polyethylene (PE). The fineness of the long fibers forming the fiber assembly 152 is preferably 1 to 50 dtex, more preferably 2 to 10 dtex. In addition, each fiber assembly may be composed of fibers having substantially the same fineness, or each fiber assembly may include fibers having different finenesses.
　また、清掃時の掃き出し機能を向上させるためには、剛性の高い繊維、すなわち繊度が高い繊維を含む繊維集合体を用いるのが好ましい。また、繊維集合体は、捲縮繊維を有する構成されるのが好ましい。ここでいう捲縮繊維は、所定の巻き縮み処理が付与された繊維として構成され、繊維同士が絡み易い構造とされる。このような捲縮繊維を用いると、繊維集合体が清掃体ホルダ装着前の状態よりも嵩高となり、更に捲縮部分にごみを取り込み易い構造とされる。本構造は、特にトウ繊維から形成された捲縮繊維を用いることによって実現され得る。 Also, in order to improve the sweeping function at the time of cleaning, it is preferable to use a fiber assembly including fibers having high rigidity, that is, fibers having high fineness. In addition, the fiber assembly is preferably configured to have crimped fibers. 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 assembly 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.
　清掃体１４０は、短冊片１４３を有する。
　図６に示すように、保持シート１６０は、清掃体１４０の長辺方向において、基材シート１５１よりも長辺方向が短い長方形状の不織布で形成されたシートである。保持シート１６０は、清掃体１４０の短辺方向（長手交差方向X）に複数のジグザグ状の短冊片１６０ａが並列状に延在している。また、基材シート１５１は、清掃体１４０の短辺方向（長手交差方向Ｘ）に複数のジグザグ状の短冊片１５１ａが並列状に延在している。
　すなわち、清掃体１４０における短冊片１４３は、保持シート１６０の短冊片１６０ａと、基材シート１５１の短冊片１５１aとにより形成される。一方、清掃体１４０として短冊片１４３を有していれば足りるものである。すなわち、清掃体１４０の短冊片１４３としては、保持シート１６０の短冊片１６０ａか、基材シート１５１の短冊片１５１ａかのいずれか一方でも足りるものである。
この短冊片１４３、１６０ａ、１５１aが、本発明における「短冊片」に対応する実施構成例である。
　なお、複数の短冊片１４３における長手交差方向Ｘの長さは、それぞれ同一のものである。 The cleaning body 140 has a strip piece 143.
As shown in FIG. 6, the holding sheet 160 is a sheet formed of a rectangular nonwoven fabric whose long side direction is shorter than the base sheet 151 in the long side direction of the cleaning body 140. In the holding sheet 160, a plurality of zigzag strips 160 a extend in parallel in the short side direction (longitudinal crossing direction X) of the cleaning body 140. The base sheet 151 has a plurality of zigzag strips 151a extending in parallel in the short side direction (longitudinal crossing direction X) of the cleaning body 140.
That is, the strip 143 in the cleaning body 140 is formed by the strip 160 a of the holding sheet 160 and the strip 151 a of the base sheet 151. On the other hand, it is sufficient to have the strip 143 as the cleaning body 140. That is, as the strip piece 143 of the cleaning body 140, either the strip piece 160a of the holding sheet 160 or the strip piece 151a of the base sheet 151 is sufficient.
These strip pieces 143, 160a, 151a are implementation configuration examples corresponding to the “strip pieces” in the present invention.
In addition, the length of the longitudinal cross direction X in the plurality of strip pieces 143 is the same.
　なお、清掃体１４０において、短冊片１４３が存在する長手方向Ｙに延びる領域を、第１清掃体領域１４１とする。一方、清掃体１４０において、短冊片１４３が存在しない長手方向Ｙに延びる領域を第２清掃体領域１４２とする。
　この第１清掃体領域１４１、第２清掃体領域１４２が、本発明における「第１清掃シート領域」、「第２清掃シート領域１４２」に対応する実施構成例である。 In the cleaning body 140, an area extending in the longitudinal direction Y where the strip 143 exists is defined as a first cleaning body area 141. On the other hand, in the cleaning body 140, an area extending in the longitudinal direction Y where the strip 143 does not exist is defined as a second cleaning body area 142.
This 1st cleaning body area | region 141 and the 2nd cleaning body area | region 142 are the implementation structural examples corresponding to the "1st cleaning sheet area | region" and the "2nd cleaning sheet area | region 142" in this invention.
　第１清掃体領域１４１は、清掃体１４０における長手交差方向Ｘ上の両端部にそれぞれ設けられ、第２清掃体領域１４２は、一対の第１清掃体領域１４１の間に設けられる。
　なお、第１清掃体領域１４１は、清掃体１４０における長手交差方向Ｘ上の一方の端部のみを含む領域として設けることも可能である。 The first cleaning body region 141 is provided at both ends of the cleaning body 140 in the longitudinal cross direction X, and the second cleaning body region 142 is provided between the pair of first cleaning body regions 141.
In addition, the 1st cleaning body area | region 141 can also be provided as an area | region including only one edge part on the longitudinal cross direction X in the cleaning body 140. FIG.
　基材シート１５１、清掃対象側シート１５３および保持シート１６０を構成する不織布は、いずれも典型的には熱溶融性繊維（熱可塑性繊維）からなるシート状の不織布が使用されている。すなわち、これら基材シート１５１、清掃対象側シート１５３および保持シート１６０は、「不織布シート」とも称呼される。なお、清掃時の掃き出し機能を向上させるためには、剛性の高い不織布を用いるのが好ましい。また、各シートの短冊片をジクザグ状とすることによって、ごみを引っ掛けて捕捉し易い清掃機能の高い構造が実現される。なお、短冊片の形状に関しては、ジクザグ状、直線状、曲線状などのうちの単一種類或いは複数種類の形状を適宜用いることができる。 As the non-woven fabric constituting the base sheet 151, the cleaning target side sheet 153, and the holding sheet 160, a sheet-like non-woven fabric made of heat-meltable fibers (thermoplastic fibers) is typically used. That is, the base material sheet 151, the cleaning target side sheet 153, and the holding sheet 160 are also referred to as “nonwoven fabric sheets”. 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. Further, by forming the strips of each sheet in a zigzag shape, a structure with a high cleaning function that can easily catch and capture dust is realized. In addition, regarding the shape of the strip, 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.
　図６に示すように、清掃体本体１５０と保持シート１６０は、清掃体１４０の中央部分を清掃体１４０の長辺方向に延在する中央溶着線１７０と、中央溶着線１７０の両側に位置する複数の円形の溶着接合部１７１、１７２、１７３にて溶着接合されている。すなわち、図７に示すように、清掃体本体１５０を構成する基材シート１５１、繊維集合体１５２、清掃対象側シート１５３の各シートと、保持シート１６０が、中央溶着線１７０において溶着接合されている。また、清掃体本体１５０のうちの基材シート１５１と繊維集合体１５２の一部と、保持シート１６０が、溶着接合部１７１、１７２、１７３において溶着接合されている。 As shown in FIG. 6, the cleaning body main body 150 and the holding sheet 160 are positioned on both sides of the central welding line 170 that extends the central portion of the cleaning body 140 in the long side direction of the cleaning body 140 and the central welding line 170. A plurality of circular welded joints 171, 172, and 173 are welded and joined. That is, as shown in FIG. 7, the base sheet 151, the fiber assembly 152, and the cleaning target side sheet 153 constituting the cleaning body main body 150 and the holding sheet 160 are welded and joined at the center welding wire 170. Yes. Further, the base sheet 151 and a part of the fiber assembly 152 in the cleaning body main body 150 and the holding sheet 160 are welded and joined at welding joints 171, 172, and 173.
　以上の通り各シートが溶着接合されることによって、中央溶着線１７０と溶着接合部１７１、１７２、１７３との間には、清掃体１４０の長辺方向に延在する一対の保持空間１８０が形成されている。また、保持空間１８０における清掃体１４０の長辺方向の両端には、開口１８１それぞれが形成されている。この保持空間１８０が、本発明における「挿入部」に対応する実施構成例である。
　なお、換言すると、保持空間１８０は、一対の溶着接合部１７１、１７２、１７３との間における保持シート１６０の所定領域と、基材シート１５１の所定領域とにより形成される。この内、保持空間１８０における清掃用具１００の上側（図３の上側）に位置する保持シート１６０の所定領域を第１挿入領域１８０Ａとする。また、保持空間１８０における清掃用具１００の下側（図３の下側）に位置する基材シート１５１の所定領域を第２挿入領域１８０Ｂとする。この第１挿入領域１８０Ａ、第２挿入領域１８０Ｂが、本発明における「第１挿入領域」、「第２挿入領域」に対応する実施構成例である。 As described above, a pair of holding spaces 180 extending in the long side direction of the cleaning body 140 are formed between the center welding wire 170 and the welding joints 171, 172, and 173 by welding the sheets. 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 insertion area 180A. In addition, a predetermined area 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 insertion area 180B. The first insertion area 180A and the second insertion area 180B are implementation configuration examples corresponding to the “first insertion area” and the “second insertion area” in the present invention.
　複数の溶着接合部１７１、１７２、１７３は、清掃体１４０の長辺方向において、曲線状に列を形成するように配置されている。すなわち、開口１８１側の溶着接合部１７１は、清掃体１４０の短辺方向において、中央溶着線１７０に近接して配置されている。一方、溶着接合部１７２は、清掃体１４０の長辺方向における両端の開口１８１の間の中間領域１８２に配置され、溶着接合部１７１に比べて、中央溶着線１７０から離間して配置されている。溶着接合部１７３は、中央溶着線１７０からさらに離間して配置されている。これにより、保持空間１８０は、清掃体１４０の短辺方向における、開口１８１の断面積よりも中間領域１８２の断面積が大きい構成となっている。換言すると、保持空間１８０は、清掃体１４０の厚さ方向において、開口部１８１よりも中間領域１８２の変位量が大きい構成となっている。 The plurality of welded joints 171, 172, and 173 are arranged so as to form a line in a curved shape 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.
　溶着接合部の内、溶着接合部１７１は、保持シート１６０と基材シート１５１の境界に配置される。溶着接合部１７２は、清掃体１４０における第１清掃体領域１４１と第２清掃体領域１４２の境界に配置される。溶着接合部１７３は、第１清掃体領域１４１内に配置される。 Among the welded joints, the welded joints 171 are disposed at the boundary between the holding sheet 160 and the base sheet 151. The weld joint 172 is disposed at the boundary between the first cleaning body region 141 and the second cleaning body region 142 in the cleaning body 140. The weld joint 173 is disposed in the first cleaning body region 141.
（清掃体ホルダと清掃体の係合）
　次に図８を参照しつつ、清掃体ホルダ１１０と清掃体１４０の係合について説明する。図８に示すように、保持部材１３１はそれぞれ、保持空間１８０に挿入が可能とされている。保持部材１３１が保持空間１８０に挿入されることで、清掃体１４０が清掃体ホルダ１１０に保持される。 (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 FIG. 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.
　清掃体１４０が清掃体ホルダ１１０に保持されている状態においては、保持部材１３１が、長手交差方向Ｘに関して、第１清掃体領域１４１と第２清体領域１４２の双方に亘って配置される。
　すなわち、保持部材１３１における基部１３２部分の端部と、先端部１３３とが第２清掃体領域１４２に配置される。そして、保持部材１３１における中間部１３４の内、特に第１最外部１３４Ｘを有する領域が第１清掃体領域１４１に配置される。 In a state where the cleaning body 140 is held by the cleaning body holder 110, the holding member 131 is disposed across both the first cleaning body area 141 and the second clean body area 142 in the longitudinal cross direction X.
That is, the end portion of the base portion 132 portion of the holding member 131 and the distal end portion 133 are disposed in the second cleaning body region 142. Of the intermediate portion 134 of the holding member 131, the region having the first outermost part 134 </ b> X is disposed in the first cleaning body region 141.
　この結果、清掃体１４０を清掃体ホルダ１１０に保持させた状態にあっては、短冊片１４３における長手交差方向Ｘの長さを異ならせることができる。すなわち、保持部材１３１が第２清掃体領域１４２に配置されている領域においては、短冊片１４３の長手交差方向Ｘの長さは、清掃体１４０に形成された短冊片１４３の長手交差方向Ｘの長さと同一である。一方、保持部材１３１が第１清掃体領域１４１に配置されている領域においては、短冊片１４３の長手交差方向Ｘの長さは、清掃体１４０に形成された短冊片１４３の長手交差方向Ｘの長さよりも短いこととなる。 As a result, when the cleaning body 140 is held by the cleaning body holder 110, the lengths of the strip pieces 143 in the longitudinal crossing direction X can be varied. That is, in the region where the holding member 131 is disposed in the second cleaning body region 142, the length of the strip piece 143 in the longitudinal cross direction X is the length of the strip piece 143 formed in the cleaning body 140 in the longitudinal cross direction X. It is the same as the length. On the other hand, in the region where the holding member 131 is disposed in the first cleaning body region 141, the length of the strip piece 143 in the longitudinal cross direction X is the same as that of the strip piece 143 formed in the cleaning body 140. It will be shorter than the length.
　すなわち、保持部材１３１の第１最外部１３４Ｘが形成されている領域の短冊片１４３は、その他の領域における保持部材１３１が配置されている短冊片に比して、剛性を高めることができる。
　なお、保持部材１３１の中間部１３４は、第１最外部１３４Ｘを極大値とする曲線状に形成されている。よって、清掃体１４０を清掃体ホルダ１１０に保持させた状態にあっては、中間部１３４の端部側短冊片１４３から、中間部１３４の第１最外部１３４Ｘ側の短冊片１４３に向かい、段階的に短冊片１４３の剛性を上げることが可能となる。 That is, the strip 143 in the region where the first outermost part 134X of the holding member 131 is formed can have higher rigidity than the strip in which the holding member 131 is disposed in other regions.
Note that the intermediate portion 134 of the holding member 131 is formed in a curved shape having the first outermost portion 134X as a maximum value. Therefore, in a state where the cleaning body 140 is held by the cleaning body holder 110, the strip portion 143 of the intermediate portion 134 moves from the end portion side strip 143 toward the strip portion 143 on the first outermost 134 X side of the intermediate portion 134, In particular, the rigidity of the strip 143 can be increased.
　よって、ユーザは、高い剛性を有する第１最外部１３４Ｘ側の短冊片にて、被清掃面のゴミやほこりを容易に払うことができることとなる。 Therefore, the user can easily remove dust and dust on the surface to be cleaned with the strips on the first outermost 134X side having high rigidity.
　次に、図９～図１１に基づき、清掃体ホルダ１１０を清掃体１４０に挿入する際の動作につき説明する。
　まず、図９に示すように、清掃体ホルダ１１０を挿入方向Ｙ１に移動させる。そして、清掃体ホルダ１１０の先端部１３３を、清掃体１４０の開口１８１に位置決めする。
　この際、一対の開口１８１の間における長手交差方向Ｘの長さは、一対の先端部１３３の間における長手交差方向Ｘの長さよりも短く形成されている。
　よって、先端部１３３を開口１８１に挿入した状態で、清掃体ホルダ１１０を挿入方向に移動させると、一対の保持部材１３１がそれぞれ内側方向Ｄ２に湾曲される。 Next, the operation when the cleaning body holder 110 is inserted into the cleaning body 140 will be described with reference to FIGS.
First, as shown in FIG. 9, the cleaning body holder 110 is moved in the insertion direction Y1. And the front-end | tip part 133 of the cleaning body holder 110 is positioned in the opening 181 of the cleaning body 140. FIG.
At this time, the length in the longitudinal cross direction X between the pair of openings 181 is formed to be shorter than the length in the longitudinal cross direction X between the pair of tip portions 133.
Therefore, when the cleaning body holder 110 is moved in the insertion direction in a state where the distal end portion 133 is inserted into the opening 181, the pair of holding members 131 are curved in the inner direction D2.
　次に、図１０に示すように、第１凸部１３７が溶着接合部１７１に当接する。この状態において、さらに清掃体ホルダ１１０を挿入方向Ｙ１に移動させると、第１凸部１３７の第２最外部１３７Ｘを経過するまで一対の保持部材１３１がそれぞれ内側方向Ｄ２に湾曲される。そして、第１凸部１３７の第２最外部１３７Ｘが溶着接合部１７１を超えると、一対の保持部材１３１がそれぞれ外側方向Ｄ１へ復帰しようとする。 Next, as shown in FIG. 10, the first convex portion 137 comes into contact with the welded joint portion 171. In this state, when the cleaning body holder 110 is further moved in the insertion direction Y1, the pair of holding members 131 are bent in the inner direction D2 until the second outermost portion 137X of the first convex portion 137 has passed. And if the 2nd outermost part 137X of the 1st convex part 137 exceeds the welding junction part 171, a pair of holding member 131 will each return to the outer side direction D1.
　ここで、図１１に示すように、第１凸部１３７が溶着接合部１７１を超えた状態においては、一対の保持部材１３１における外側方向Ｄ１の復帰動作は、溶着接合部１７１により規制される。さらに清掃体ホルダ１１０を挿入方向Ｙ１に移動させると、一対の保持部材１３１は、第１最外部１３４Ｘまでは内側方向Ｄ２に湾曲する方向に動作し、第１最外部１３４Ｘを超えると外側方向Ｄ１へ復帰する方向へ動作する。これに伴い、第１凸部１３７も同様の動作を行う。
　すなわち、清掃体ホルダ１１０の挿入方向Ｙ１の挿入動作に伴い、第１凸部１３７が溶着接合部１７１以外の溶着接合部１７２、１７３に接触する可能性を低減することができる。 Here, as shown in FIG. 11, in the state where the first convex portion 137 exceeds the welding joint portion 171, the return operation in the outer direction D <b> 1 in the pair of holding members 131 is regulated by the welding joint portion 171. When the cleaning body holder 110 is further moved in the insertion direction Y1, the pair of holding members 131 operates in a direction that curves in the inner direction D2 up to the first outermost part 134X, and beyond the first outermost part 134X, the outer direction D1. Operates in the direction to return to. Accordingly, the first protrusion 137 performs the same operation.
That is, with the insertion operation of the cleaning body holder 110 in the insertion direction Y <b> 1, the possibility that the first convex portion 137 contacts the weld joint portions 172 and 173 other than the weld joint portion 171 can be reduced.
　また、清掃体ホルダ１１０が清掃体１４０に保持されている状態から、清掃体ホルダ１１０を引抜方向Ｙ２へ移動させた場合には、上記の動作と逆の動作が行われる。
　すなわち、清掃体ホルダ１１０の第２凸部１３８が溶着接合部１７１を乗り越えた後において、一対の保持部材１３１は、第１最外部１３４Ｘまでは内側方向Ｄ２に湾曲する方向に動作し、第１最外部１３４Ｘを超えると外側方向Ｄ１へ復帰する方向へ動作する。これに伴い、第１凸部１３７も同様の動作を行う。
　よって、清掃体ホルダ１１０の引抜方向Ｙ２の挿入動作に伴い、第１凸部１３７が溶着接合部１７１以外の溶着接合部１７２、１７３に接触する可能性を低減することができる。 In addition, when the cleaning body holder 110 is moved in the drawing direction Y2 from the state where the cleaning body holder 110 is held by the cleaning body 140, the operation opposite to the above operation is performed.
That is, after the second convex portion 138 of the cleaning body holder 110 gets over the welded joint portion 171, the pair of holding members 131 operate in the direction of bending in the inner direction D2 until the first outermost portion 134X. If it exceeds the outermost part 134X, it will move in the direction of returning to the outer direction D1. Accordingly, the first protrusion 137 performs the same operation.
Therefore, with the insertion operation of the cleaning body holder 110 in the pulling-out direction Y2, the possibility that the first convex portion 137 contacts the welding joint portions 172 and 173 other than the welding joint portion 171 can be reduced.
　つまり、本実施形態に係る清掃用具１００においては、清掃体ホルダ１１０を清掃体１４０に挿入する場合や、清掃体ホルダ１１０を清掃体１４０から引抜く場合において、ユーザがスムーズな動作を行うことができるものである。 That is, in the cleaning tool 100 according to the present embodiment, when the cleaning body holder 110 is inserted into the cleaning body 140 or when the cleaning body holder 110 is pulled out from the cleaning body 140, the user can perform a smooth operation. It can be done.
　また、本実施形態によれば、清掃対象側シート１５３の短冊片１５３ａの幅を基材シート１５１の短冊片１５１ａよりも小さい構成としているため、繊維集合体１５２の繊維が清掃対象側シート１５３の短冊片１５３ａに絡み付き易い構造を実現することが可能となる。すなわち、清掃体１４０における清掃対象に対向する面の短冊片１５３ａと繊維が絡むことにより、清掃体１４０の清掃対象に対向する側をよりボリュームアップすることになる。したがって、塵や埃を捕捉する清掃機能が向上する。一方、基材シート１５１の短冊片１５１ａや保持シート１６０の短冊片１６０ａは、清掃対象側シート１５３の短冊片１５３ａよりも繊維集合体１５２の繊維に絡みづらくなっている。そのため、短冊片１５１ａと短冊片１６０ａは、繊維集合体１５２の動きとは独立して埃掃き出し機能を発揮することができる。 Moreover, according to this embodiment, since the width of the strip 153a of the cleaning target side sheet 153 is smaller than that of the strip 151a of the base sheet 151, the fibers of the fiber assembly 152 are the same as the cleaning target 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.
　なお、本実施形態では、溶着接合部１７１、１７２、１７３は、中央溶着線１７０に対して対称に配置されているだけでなく、中央溶着線１７０の中心を通り、中央溶着線１７０に垂直な直線に対しても対称に配置されていることが好ましい。このような構成によれば、いずれの開口１８１からでも保持部材１３１を保持空間１８０に挿入させることができる。 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.
　なお、本発明は上記の実施の形態のみに限定されるものではなく、種々の応用や変形が考えられる。例えば、上記実施形態を応用した次の各変形例を実施することもできる。 Note that the present invention is not limited to the above-described embodiment, and various applications and modifications are possible. For example, the following modifications that apply the above embodiment may be implemented.
（第１変形例）
　次に、図１２～図１４に基づき第１変形例を説明する。なお、第１変形例に係る清掃用具は、第１の実施形態の清掃用具１００に比して、清掃体ホルダ１１０における清掃体保持部１３０の構成が異なるものである。 (First modification)
Next, a first modification will be described based on FIGS. In addition, the cleaning tool which concerns on a 1st modification differs in the structure of the cleaning body holding | maintenance part 130 in the cleaning body holder 110 compared with the cleaning tool 100 of 1st Embodiment.
　つまり、第１変形例における清掃体保持部１３０の中間部１３４は、第１弾性部材１３５と第２弾性部材１３６で構成されている。すなわち、第１弾性部材１３５と第２弾性部材１３６は、基部１３２側と先端部１３３側で互いに連結されている。そして、基部１３２と先端部１３３の中間部分の領域においては、第１弾性部材１３５と第２弾性部材１３６が互いに離間するように構成されている。図１３に示すように、第１弾性部材１３５は、基部１３２と先端部１３３の中間部分の領域において、基部１３２と先端部１３３より清掃体ホルダ１１０の下方（図１３の下方）に突出している。一方、第２弾性部材１３６は、当該領域において、基部１３２と先端部１３３より清掃体ホルダ１１０の上方（図１３の上方）に突出している。 That is, the intermediate part 134 of the cleaning body holding part 130 in the first modified example includes the first elastic member 135 and the second elastic member 136. That is, the first elastic member 135 and the second elastic member 136 are connected to each other on the base 132 side and the distal end 133 side. And in the area | region of the intermediate part of the base 132 and the front-end | tip part 133, it is comprised so that the 1st elastic member 135 and the 2nd elastic member 136 may mutually space apart. As shown in FIG. 13, the first elastic member 135 protrudes below the cleaning body holder 110 (downward in FIG. 13) from the base portion 132 and the distal end portion 133 in the region between the base portion 132 and the distal end portion 133. . On the other hand, the second elastic member 136 protrudes above the cleaning body holder 110 (upward in FIG. 13) from the base portion 132 and the tip end portion 133 in the region.
　また、図１２に示すように、一方の保持部材１３１の第１弾性部材１３５と、他方の保持部材１３１の第１弾性部材１３５は、基部１３２と先端部１３３の中間部分の領域において、互いに近接するように配置されている。また、一方の保持部材１３１の第２弾性部材１３６と、他方の保持部材１３１の第２弾性部材１３６は、当該領域において、互いに離間するように配置されている。 In addition, as shown in FIG. 12, the first elastic member 135 of one holding member 131 and the first elastic member 135 of the other holding member 131 are close to each other in the region between the base portion 132 and the distal end portion 133. Are arranged to be. In addition, the second elastic member 136 of one holding member 131 and the second elastic member 136 of the other holding member 131 are arranged so as to be separated from each other in the region.
　以上のように構成された中間部１３４は、１つの保持部材１３１を構成する第１弾性部材１３５と第２弾性部材１３６が、基部１３２と先端部１３３の中間部分の領域において、清掃体ホルダ１１０の上下方向および左右方向において最も離間するように配置されている。これらの離間距離は、図１２における清掃体ホルダ１１０の左右方向離間距離Ｗおよび、図１３における清掃ホルダ１１０の上下方向離間距離Ｄで示される。第１弾性部材１３５、第２弾性部材１３６は、樹脂材料で成型されているため、弾性変形によって、清掃体ホルダ１１０の上下方向および左右方向に撓むように構成されている。なお、清掃体ホルダ１１０の上下方向における上下方向離間距離Ｄ、すなわち、清掃体ホルダ１１０の初期状態における上下方向離間距離Ｄは、第１弾性部材１３５と第２弾性部材１３６を弾性変形によって上下方向に近接させた状態における第１弾性部材１３５と第２弾性部材１３６の距離に対する比率が２５０％以上であることが好ましい。 The intermediate portion 134 configured as described above is configured so that the first elastic member 135 and the second elastic member 136 constituting one holding member 131 are in the region of the intermediate portion between the base portion 132 and the distal end portion 133. Are arranged so as to be most separated in the vertical direction and the horizontal direction. These separation distances are indicated by a separation distance W in the horizontal direction of the cleaning body holder 110 in FIG. 12 and a separation distance D in the vertical direction of the cleaning holder 110 in FIG. Since the first elastic member 135 and the second elastic member 136 are molded of a resin material, the first elastic member 135 and the second elastic member 136 are configured to bend in the vertical direction and the horizontal direction of the cleaning body holder 110 by elastic deformation. Note that the vertical separation distance D in the vertical direction of the cleaning body holder 110, that is, the vertical separation distance D in the initial state of the cleaning body holder 110 is the vertical direction by elastically deforming the first elastic member 135 and the second elastic member 136. It is preferable that the ratio of the first elastic member 135 and the second elastic member 136 to the distance between the first elastic member 135 and the second elastic member 136 is 250% or more.
　図１２に示すように、第２弾性部材１３６の側面には、凸部１３７、１３８が形成されている。すなわち、第２弾性部材１３６の先端部１３３側には、凸部１３７が形成されており、第２弾性部材１３６の基部１３２側には、凸部１３８が形成されている。これらの凸部１３７、１３８は、平面視で半円状に形成されている。 As shown in FIG. 12, convex portions 137 and 138 are formed on the side surface of the second elastic member 136. That is, a convex portion 137 is formed on the distal end 133 side of the second elastic member 136, and a convex portion 138 is formed on the base 132 side of the second elastic member 136. These convex portions 137 and 138 are formed in a semicircular shape in plan view.
　次に図１４を参照しつつ、清掃体ホルダ１１０と清掃体１４０の係合について説明する。
　保持空間１８０の開口１８１の幅は、第１保持部材１３５と第２保持部材１３６の左右方向離間距離Ｗまたは上下方向離間距離Ｄのうちの大きい方よりも、小さく形成されている。そのため、保持部材１３１を保持空間１８０に挿入する過程において、第１弾性部材１３５と第２保持部材１３６は、開口１８１を通過する際に、互いに近接するように弾性変形する。 Next, the engagement between the cleaning body holder 110 and the cleaning body 140 will be described with reference to FIG.
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.
　第１弾性部材１３５と第２弾性部材１３６が開口１８１を通過した後は、復元力により、第１弾性部材１３５と第２弾性部材１３６は、基部１３２と先端部１３３の中間領域において、互いに離れる方向に変形する。すなわち、初期状態に戻るように変形する。これにより、図１４に示すように、保持空間１８０が、第１弾性部材１３５と第２弾性部材１３６によって上下方向に拡張される。 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 to return to the initial state. Thereby, as shown in FIG. 14, the holding space 180 is expanded in the vertical direction by the first elastic member 135 and the second elastic member 136.
　保持空間１８０への保持部材１３１の挿入が完了すると、凸部１３７、１３８が溶着接合部１７２の間に保持される。また、図１４に示すように、第１弾性部材１３５と第２弾性部材１３６の復元力によって、第１弾性部材１３５は、保持シート１６０を上方に押し上げ、第２弾性部材１３６は、基材シート１５１を下方に押し下げる。これにより、保持空間１８０内において、保持部材１３１が中間領域１８２に係合される。このとき、押え板１３９が清掃体１４０を上方から押えつけるとともに、押え板１３９の下面に設けられた係止突部（図示省略）が清掃体１４０の抜け止めとして作用する。これにより、清掃体１４０が清掃体保持部１３１によって確実に保持される。なお、保持部材１３０は、清掃体１４０の両端に形成されたいずれの開口１８１から保持空間１８０に挿入させてもよい。 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. As shown in FIG. 14, 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. Thereby, 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.
　以上の第１変形例によれば、清掃体１４０が清掃体ホルダ１１０に保持された状態において、清掃体保持部１３０が清掃体１４０を上下方向に拡張させて保持する。すなわち、保持部材１３１が弾性変形可能な第１弾性部材１３５と第２弾性部材１３６で形成されており、第１弾性部材１３５と第２弾性部材１３６の復元力によって、清掃体１４０を厚さ方向に拡張している。そのため、清掃体１４０の嵩が高められた状態で保持される。 According to the above first modified example, in a state where the cleaning body 140 is held by the cleaning body holder 110, the cleaning body holding part 130 expands 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 to. Therefore, the cleaning body 140 is held in an increased state.
　特に、繊維集合体１５２の嵩が高められた状態となる。繊維集合体１５２の嵩が高められた状態は、ボリューム感の高い状態として規定することができ、「嵩高状態」、「ボリュームアップ状態」、「空間充満度の高い状態」或いは「バルキー度の高い状態」ということもできる。
　したがって、繊維集合体１５２の嵩を高めることによって清掃効果向上を図ることが可能となる。また、繊維集合体１５２の嵩が高められることによって、被清掃面に対する密着の度合いが高まり、繊維集合体１５２の汚れが際立ち易く（黒くなり易く）なり、使用者はゴミが確実に捕捉されているという実感が得られることとなり満足度が高まる。 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. Further, 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 likely to stand out (is likely to become black), and the user can reliably catch dust. The satisfaction will be increased.
　また、第１変形例によれば、第１弾性部材１３５と第２弾性部材１３６は、清掃体ホルダ１１０の上下方向に離間しているだけでなく、清掃体ホルダ１１０の左右方向にも離間している。すなわち、第１弾性部材１３５と第２弾性部材１３６は、清掃体１４０の厚さ方向に離間して配置され、清掃体１４０を嵩高に保持するだけでなく、清掃体１４０の厚さ方向に交差する方向に離間して配置され、平面視における清掃体１４０の面積を確保している。換言すると、清掃体１４０は、平面視における面積が小さくなることを抑制しつつ、嵩高に保持される。したがって、清掃体１４０を広範な範囲で嵩高に保持することができ、清掃効率を向上することができる。 Further, according to the first modification, 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. ing. 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.
　清掃体１４０が清掃体ホルダ１１０に保持された状態では、保持部材１３１が保持空間１８０の内部を拡張する方向に押圧する。保持空間１８０は、保持シート１６０により形成された第１挿入領域１８０Ａと、基材シート１５１により形成された第２挿入領域１８０Ｂとの間に形成されている。つまり、保持部材１３１の第１弾性部材１３５が、保持空間１８０の第２挿入領域１８０Ｂを押圧する。また、保持部材１３１の第２弾性部材１３６が、保持空間１８０の第１挿入領域１８０Ａを押圧する。この結果、保持空間１８０における、第１挿入領域１８０Ａと第２挿入領域１８０Ｂとには張力が付与される。すなわち、保持部材１３１における第１弾性部材１３５と第２弾性部材とは、特に保持空間１８０における第２挿入領域１８０Bに所定の張力を与えるテンション付与部１９０とされる。さらに、第２弾性部材１３６は、第１テンション付与部１９０Ａとされる。さらに、第１弾性部材１３５は、第２テンション付与部材１９０Ｂとされる。 In the 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. The holding space 180 is formed between the first insertion region 180 </ b> A formed by the holding sheet 160 and the second insertion region 180 </ b> B formed by the base sheet 151. That is, the first elastic member 135 of the holding member 131 presses the second insertion region 180 </ b> B of the holding space 180. Further, the second elastic member 136 of the holding member 131 presses the first insertion region 180 </ b> A of the holding space 180. As a result, tension is applied to the first insertion region 180A and the second insertion region 180B in the holding space 180. That is, the first elastic member 135 and the second elastic member in the holding member 131 serve as a tension applying unit 190 that applies a predetermined tension to the second insertion region 180B in the holding space 180, in particular. 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.
　一方、第１弾性部材１３５は、第２弾性部材１３６よりも長手交差方向Ｘにおける内側に配置されている。すなわち、第２テンション付与部１９０Ｂは、第１テンション付与部１９０Ａよりも長手交差方向Ｘにおける内側に配置されている。
　よって、第２領域１８０Ｂは、第２テンション付与部１９０Ｂ（第１弾性部材１３５）から第１テンション付与部１９０Ａ（第２弾性部材１３６）に亘り、下から上（図１３の下から上）方向へテンションを付与されつつ傾斜される。すなわち、第２挿入領域１８０Ｂは、テンション部１９１を形成する。 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.
Accordingly, the second region 180B extends from the second tension applying portion 190B (first elastic member 135) to the first tension applying portion 190A (second elastic member 136) from the bottom to the top (from the bottom to the top in FIG. 13). It is tilted while being tensioned. That is, the second insertion region 180B forms a tension portion 191.
　この結果、第２挿入領域１８０Ｂは、第１挿入領域１８０Ａが配置されている方向（図１３の上方）へ傾斜される。さらに、第２挿入領域１８０Ｂと連続されている短冊片１６０ａ、１５１ａも第１挿入領域１８０Ａが配置されている方向（図１３の上方）へ移動される。 As a result, the second insertion region 180B is inclined in the direction in which the first insertion region 180A is arranged (upward in FIG. 13). Further, the strip pieces 160a and 151a that are continuous with the second insertion region 180B are also moved in the direction in which the first insertion region 180A is arranged (upward in FIG. 13).
　この結果、清掃体１４０においては、短冊片１６０ａ、１５１aと、清掃対象側シート１５３の距離が離間される。すなわち、清掃体１４０が清掃対象に接するべき領域を増加させることができる。
　さらに、この種の繊維集合体１５２を有する清掃用具１００にあっては、使用前にユーザが清掃具１００を振って繊維集合体１５２を開繊させる場合がある。本発明においては、繊維集合体１５２が開繊されるべき領域を確保できる。よって、繊維集合体１５２の開繊状態が良好なものとなる。 As a result, in the cleaning body 140, the distance between the strip pieces 160a and 151a 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.
　さらに、清掃体保持部１３０は二股状に、２つの保持部材１３１で形成されているため、清掃体ホルダ１１０が、清掃体１４０を嵩高に保持する状態において、清掃体１４０の平面視における面積が小さくなることをさらに抑制することができる。 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.
　また、第１変形例によれば、第１弾性部材１３５と第２弾性部材１３６は、基部１３２と先端部１３３から等距離に位置する中間部分において、清掃体ホルダ１１０の上下方向および左右方向において最も離間している。そのため、清掃体ホルダ１１０によって保持された清掃体１４０の中心において、清掃体１４０を最も嵩高にすることができる。これにより、清掃体１４０を効率的に嵩高に保持することができる。 Further, according to the first modified example, the first elastic member 135 and the second elastic member 136 are arranged in the vertical direction and the horizontal direction of the cleaning body holder 110 at an intermediate portion located at an equal distance from the base portion 132 and the distal end portion 133. Most distant. 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.
　また、第１変形例によれば、清掃体１４０が清掃体ホルダ１１０に保持された状態において、第１弾性部材１３５と第２弾性部材１３６の復元力によって、保持空間１８０内で、保持部材１３１が中間領域１８２に係合される。すなわち、第１弾性部材１３５と第２弾性部材１３６の復元力によって、清掃中に清掃体１４０が清掃体ホルダ１１０から抜けることを抑制することができる。 Further, according to the first modification, 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 when the cleaning body 140 is held by the cleaning body holder 110. Is engaged 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.
　（第２変形例）
　次に、図１５～図２４に基づき、第２変形例を説明する。第２弾性部材２３６は、凸部２３７と、凸部２３８とを有する。凸部２３７は、第２弾性部材２３６の先端部２３３側に設けられる。凸部２３８は、第２弾性部材２３６の基部２３２側に設けられる。 (Second modification)
Next, a second modification will be described based on FIGS. The second elastic member 236 has a convex part 237 and a convex part 238. The convex portion 237 is provided on the tip end portion 233 side of the second elastic member 236. The convex part 238 is provided on the base part 232 side of the second elastic member 236.
　凸部２３７は、挿入方向Ｙ１側に設けられた挿入側領域２３７Ａと、引抜方向Ｙ２側に設けられた引抜側領域２３７Ｃとを有する。さらに、凸部２３７は、挿入側領域２３７Ａと引抜側領域２３７Ｃとの間に設けられた中間領域２３７Ｂを有する。この挿入側領域２３７Ａ、中間領域２３７Ｂ、引抜側領域２３７Ｃが、本発明における「挿入側領域」、「中間領域」、「引抜側領域」に対応する実施構成例である。 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.
　次に、凸部２３７の構造を説明する。なお、便宜上、先端側２３３の凸部２３７の構造のみ説明するが、基部２３２側の凸部２３８が凸部２３７と同様の構成を有することができるのはもちろんである。
　図１６は、清掃体ホルダ２１０を挿入方向Ｙ１に移動させて、清掃体ホルダ２１０の保持部材２３１を、清掃体１４０の保持空間１８０に挿入する状態を示す。
　この場合、凸部２３７の挿入側領域２３７Ａが、清掃体１４０の接合部１７１Ａに当接する。この挿入側領域２３７Ａが接合部１７１Ａに最初に当接する点を、挿入開始点２３７Ａ１とする。この挿入開始点２３７Ａ１が、本発明における「挿入開始点」に対応する実施構成例である。 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 233 will be described, but the convex portion 238 on the base portion 232 side can have the same configuration as the convex portion 237.
FIG. 16 shows a state where the cleaning body holder 210 is moved in the insertion direction Y <b> 1 and the holding member 231 of the cleaning body holder 210 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.
　次に、図１７に示すように、挿入側領域２３７Ａが接合部１７１Ａに最後に当接する点まで、清掃体ホルダ２１０を挿入方向Ｙ１へさらに移動させる。この、挿入側領域２３７Ａが接合部１７１Ａに最後に当接する点を挿入終了点２３７Ａ２とする。この挿入終了点２３７Ａ２が、本発明における「挿入終了点」に対応する実施構成例である。 Next, as shown in FIG. 17, the cleaning body holder 210 is further moved in the insertion direction Y <b> 1 until the insertion side region 237 </ b> A finally comes into contact with the joint portion 171 </ b> A. 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.
　次に、図１８に示すように、清掃体ホルダ２１０を挿入方向Ｙ１へさらに移動させる。すると、接合部１７１Ａは、挿入終了点２３７Ａ２を通過して中間領域２３７Ｂに当接する。そしてさらに清掃体ホルダ２１０を挿入方向Ｙ１に移動することにより、清掃体ホルダ２１０と清掃体１４０の装着は完了する。 Next, as shown in FIG. 18, the cleaning body holder 210 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 210 in the insertion direction Y1, the mounting of the cleaning body holder 210 and the cleaning body 140 is completed.
　ここで、図１９に示すように、挿入開始点２３７Ａ１と、挿入終了点２３７Ａ２とを結んだ直線を、第１の凸部仮想直線Ｌ１とする。そして、挿入開始点２３７Ａ１を通過する挿入方向Ｙ１と平行な直線を第２の凸部仮想直線Ｌ２とする。そして、第１の凸部仮想直線Ｌ１と第２の凸部仮想直線Ｌ２とにより形成される角度を第１の角度Ａ１とする。
　この第１の凸部仮想直線Ｌ１、第２の凸部仮想直線Ｌ２、第１の角度Ａ１が、本発明における「第１の仮想直線」、「第２の仮想直線」、「第１の角度」に対応する実施構成例である。 Here, as shown in FIG. 19, a straight line connecting the insertion start point 237A1 and the insertion end point 237A2 is defined as a first convex virtual line L1. A straight line passing through the insertion start point 237A1 and parallel to the insertion direction Y1 is defined as a second convex virtual line L2. The angle formed by the first convex virtual line L1 and the second convex virtual line L2 is defined as a first angle A1.
The first convex virtual line L1, the second convex virtual line L2, and the first angle A1 are the “first virtual straight line”, “second virtual straight line”, and “first angle” in the present invention. It is an implementation structural example corresponding to "."
　図２０は、清掃体ホルダ２１０と清掃体１４０が装着されている状態から、清掃体ホルダ２１０を引抜方向Ｙ２に移動させる状態を示す。
　この場合、凸部２３７の引抜側領域２３７Ｃが、清掃体１４０の接合部１７１Ａに当接する。この引抜側領域２３７Ｃが接合部１７１Ａに最初に当接する点を、引抜開始点２３７Ｃ１とする。この引抜開始点２３７Ｃ１が、本発明における「引抜開始点」に対応する実施構成例である。 FIG. 20 shows a state in which the cleaning body holder 210 is moved in the drawing direction Y2 from the state where the cleaning body holder 210 and the cleaning body 140 are mounted.
In this case, the pull-out 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.
　次に、図２１に示すように、引抜側領域２３７Ｃが接合部１７１Ａに最後に当接する点まで、清掃体ホルダ２１０を引抜方向Ｙ２へさらに移動させる。この、引抜側領域２３７Ｃが接合部１７１Ａに最後に当接する点を引抜終了点２３７Ｃ２とする。この引抜終了点２３７Ｃ２が、本発明における「引抜終了点」に対応する実施構成例である。 Next, as shown in FIG. 21, the cleaning body holder 210 is further moved in the drawing direction Y2 until the drawing side region 237C finally comes into contact with the joint portion 171A. 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.
　次に、図２２に示すように、清掃体ホルダ２１０を引抜方向Ｙ２へさらに移動させる。すると、接合部１７１Ａは、引抜終了点２３７Ｃ２を通過して中間領域２３７Ｂに当接する。そしてさらに清掃体ホルダ２１０を引抜方向Ｙ２に移動することにより、清掃体ホルダ２１０は清掃体１４０から取り外される。 Next, as shown in FIG. 22, the cleaning body holder 210 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. Further, the cleaning body holder 210 is removed from the cleaning body 140 by moving the cleaning body holder 210 in the drawing direction Y2.
　ここで、図２３に示すように、引抜開始点２３７Ｃ１と、引抜終了点２３７Ｃ２とを結んだ直線を、第３の凸部仮想直線Ｌ３とする。そして、引抜開始点２３７Ｃ１を通過する引抜方向Ｙ２と平行な直線を第４の凸部仮想直線Ｌ４とする。そして、第３の凸部仮想直線Ｌ３と第４の凸部仮想直線Ｌ４とにより形成される角度を第２の角度Ａ２とする。
　この第３の凸部仮想直線Ｌ３、第４の凸部仮想直線Ｌ４、第２の角度Ａ２が、本発明における「第３の凸部仮想直線」、「第４の凸部仮想直線」、「第２の角度」に対応する実施構成例である。 Here, as shown in FIG. 23, a straight line connecting the drawing start point 237C1 and the drawing end point 237C2 is defined as a third convex virtual line L3. A straight line parallel to the drawing direction Y2 passing through the drawing start point 237C1 is defined as a fourth convex virtual line L4. The angle formed by the third convex virtual line L3 and the fourth convex virtual line L4 is defined as a second angle A2.
The third convex virtual line L3, the fourth convex virtual line L4, and the second angle A2 are the “third convex virtual line”, “fourth convex virtual line”, “ It is the implementation structural example corresponding to a "2nd angle".
　ここで、図２４に示すように、第１の角度Ａ１は、第２の角度Ａ２よりも小さく構成されている。これが、本発明における「前記第１の角度は、前記第２の角度よりも小さく形成されている」の実施構成例である。
　凸部２３７をこのように構成することによって、清掃体ホルダ２１０を清掃体１４０に装着する際には、スムーズに作業を行うことができる。一方、清掃用具１００を使用する際には、清掃体ホルダ２１０と清掃体１４０とが分離しにくくなる。 Here, as shown in FIG. 24, 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 as described above, when the cleaning body holder 210 is attached to the cleaning body 140, the operation can be smoothly performed. On the other hand, when the cleaning tool 100 is used, the cleaning body holder 210 and the cleaning body 140 are difficult to separate.
　（第３変形例）
　次に、図２５～図２６に基づき、第３変形例を説明する。第３変形例に係る清掃体ホルダ３１０の清掃体保持部３３０は、第１弾性部材３３５と第２弾性部材３３６とにより構成される。第２弾性部材３３６は、先端部３３３側の凸部３３７と、基部３３２側の凸部３３８とを有する。先端部３３３側の凸部３３７は、第２弾性部材３３６の先端部３３３側を外側方向に変形させることにより形成されている。 (Third Modification)
Next, a third modification will be described based on FIGS. The cleaning body holder 330 of the cleaning body holder 310 according to the third 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.
　すなわち、第３変形例に係る清掃体ホルダ３１０の先端部３３３側の凸部３３７は、第２変形例に係る清掃体ホルダ１１０の先端部１３３側の凸部２３７に比して、第２弾性部材３３６と凸部３３７との境界が明確ではないものである。
　さらに、このような構造の凸部３３７については、特に凸部３３７の挿入側領域３３７Aがどこから開始するのかが問題となる。 That is, the convex portion 337 on the distal end portion 333 side of the cleaning body holder 310 according to the third 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 second 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.
　よって、このような構造の凸部３３７に関する「第１の角度」の求め方を、図２６に基づき説明する。
　図２６は、清掃体ホルダ３１０を挿入方向Ｙ１に移動させて、清掃体ホルダ３１０の保持部材３３１を、清掃体３４０の保持空間１８０に挿入する状態を示す。
　この場合、凸部３３７が、清掃体３４０の接合部１７１Ａに当接する。この挿入側領域３３７Ａが接合部１７１Ａに最初に当接する点を、挿入開始点３３７Ａ１とする。また、この挿入開始点３３７Ａ１から中間部３３７Ｂに亘る部分を、凸部３３７の挿入側領域３３７Ａとする。
　これにより、凸部３３７のような構造であっても、上述した第３変形例と同様に、挿入開始点３３７Ａ１と、挿入終了点とを確定することが可能となる。よって、凸部３３７においても、第１の角度を決定することができる。 Therefore, how to obtain the “first angle” for the convex portion 337 having such a structure will be described with reference to FIG.
FIG. 26 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 337A first comes into contact with the joint portion 171A is set 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 determine insertion start point 337A1 and insertion end point similarly to the 3rd modification mentioned above. Therefore, the first angle can be determined also in the convex portion 337.
（第４変形例）
　次に、図２７～図２８に基づき、第４変形例を説明する。図２７～図２８においては、便宜上、第２弾性部材４３６と、先端部側の凸部４３７の構造のみを説明する。
　凸部４３７は、挿入側領域４３７Ａと、引抜側領域４３７Ｃが直線により構成されている。よって、中間領域４３７Ｂは点状となる。 (Fourth modification)
Next, a fourth modification will be described based on FIGS. 27 to 28, only the structure of the second elastic member 436 and the convex portion 437 on the tip end side will be described for the sake of convenience.
As for the convex part 437, insertion side area | region 437A and extraction side area | region 437C are comprised by the straight line. Therefore, the intermediate region 437B has a dot shape.
　図２８は、清掃体ホルダを挿入方向Ｙ１に移動させて、清掃体ホルダの保持部材を清掃体１４０の保持空間１８０に挿入する状態と、清掃体ホルダを引抜方向Ｙ２に移動させて、清掃体ホルダの保持部材を清掃体１４０の保持空間１８０から引抜く状態との双方を示す説明図である。
　このような構造の凸部４３７の場合、挿入終了点４３７Ａ２と、引抜終了点４３７Ｃ２とが、中間領域４３７Ｂにて一致することとなる。一方、挿入終了点４３７Ａ２と、引抜終了点４３７Ｃ２が凸部４３７における同一の部分であっても、「第１の角度」および「第２の角度」を求めることに何ら問題はないものである。 FIG. 28 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”.
（第５変形例）
　次に、図２９～図３０に基づき、第５変形例を説明する。図２９～図３０においては、便宜上、第２弾性部材５３６と、先端部側の凸部５３７の構造のみを説明する。
　凸部５３７は、挿入側領域５３７Aに凹部５３７ＡＡを有する。 (5th modification)
Next, a fifth modification will be described based on FIGS. 29 to 30, only the structure of the second elastic member 536 and the convex portion 537 on the tip end side will be described for the sake of convenience.
The convex portion 537 has a concave portion 537AA in the insertion side region 537A.
　図３０は、清掃体ホルダを挿入方向Ｙ１に移動させて、清掃体ホルダの保持部材を清掃体１４０の保持空間１８０に挿入する状態を示す説明図である。
　凸部５３７の場合は凹部５３７ＡＡが存在しているため、挿入領域５３７Ａと接合部１７１Ａの当接状態は、上述した第２変形例～第４変形例に係る凸部とは異なるものである。
　すなわち、凸部５３７の挿入領域５３７Ａが挿入開始点（図示せず）から挿入終了点５３７Ａ１に至るまでに、接合部１７１Ａが凹部５３７ＡＡを経由する。
　一方、仮にこのように挿入領域５３７Ａに凹部５３７ＡＡを有する構成であっても、あくまで挿入終了点５３７Ａ２は、挿入側領域５３７Ａが接合部１７１Ａに最後に当接する点である。このことは、引抜側領域５３７Ｃが凹部を有する場合であっても同様である。
　よって、凸部５３７が凹部５３７ＡＡを有する構造であっても、「第１の角度」および「第２の角度」を求めることに何ら問題はないものである。 FIG. 30 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 second to fourth 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”.
　なお、図１５～図３０に基づく第２変形例～第５変形例においては、先端部側の凸部における構成を中心に説明を行った。一方、上述した先端部側の凸部における構成を、基部側の凸部にも適宜実施可能なことはもちろんである。 In the second to fifth modifications based on FIGS. 15 to 30, the description has focused on the configuration of the convex portion on the tip 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.
　なお、図１５～図３０に基づく第２変形例～第５変形例においては、便宜上、清掃体ホルダの凸部と当接する清掃体の接合部として、「接合部１７１Ａ」のみを説明した。一方、第１の角度Ａ１と第２の角度Ａ２を求める場合、様々な形状の接合部や、様々な配置の接合部の集合に対しても適宜応用することができるのはもちろんである。
　この際、例えば清掃体における接合部の形状や、複数存在する接合部の配置形態や、さらには清掃体ホルダの中間部の構成次第においては、長手方向に連続するそれぞれの接合部に対し、第１の角度Ａ１や第２の角度Ａ２が異なった角度となる可能性がある。
　このように、複数の第１の角度Ａ１を有する場合は、最も小さい角度を本発明に係る「第１の角度」とする。
　さらに、複数の第２の角度Ａ２を有する場合は、最も大きい角度を本発明に係る「第２の角度」とする。 In the second to fifth modifications based on FIGS. 15 to 30, for convenience, only the “joining part 171A” has been described as the joining part of the cleaning body that comes into contact with the convex part 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.
　以上においては、清掃体ホルダ１１０は、二股状に、２つの保持部材１３１を有していたが、二股状に形成することなく、１つの保持部材１３１のみを有していてもよい。 In the above, 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.
