This will be explained using what was used.

以下、床面吸込具Ｓの各部について詳述する。
ケース４０は、床面吸込具Ｓの外郭下側を成す略箱形状の下ケース４１と、外郭上側を成す略箱形状の上ケース４２から成り、下ケース４１と上ケース４２が、上下に合わさることにより構成されている。Hereinafter, each part of the floor suction tool S will be described in detail.
The case 40 includes a substantially box-shaped lower case 41 that forms the lower outer side of the floor surface suction tool S, and a substantially box-shaped upper case 42 that forms the upper side of the outer shell, and the lower case 41 and the upper case 42 are aligned vertically. It is constituted by.

ケース４０の底となる下ケース４１の底板には、被清掃面から塵埃を吸込むための長手方向に開口する吸込口４１ａが形成されている。この吸込口４１ａと上ケース４２との間には、所定の空間を確保することにより、回転ブラシ６０が収納される回転ブラシ収納室４０ａが形成されている。
尚、回転ブラシ収納室４０ａの後方には、後述する接続部５０へと連通する集塵風路４５が形成されており、吸込口４１ａから吸い込まれた塵埃が、接続部５０へと流下するように構成されている。The bottom plate of the lower case 41 serving as the bottom of the case 40 is formed with a suction port 41a that opens in the longitudinal direction for sucking dust from the surface to be cleaned. A rotary brush storage chamber 40a in which the rotary brush 60 is stored is formed between the suction port 41a and the upper case 42 by securing a predetermined space.
A dust collecting air passage 45 communicating with a connecting portion 50 described later is formed behind the rotating brush storage chamber 40a so that dust sucked from the suction port 41a flows down to the connecting portion 50. It is configured.

ケース４０の後部中央には、接続部５０が取り付けられる開口である接続部取付け口４０ｅが形成されている。
この接続部取付け口４０ｅは、下ケース４１と上ケース４２の後部中央に、それぞれ切り欠き部を形成し、下ケース４１と上ケース４２が上下に合わさる際に、これらの切り欠き部が合わさることで開口が形成される。In the center of the rear part of the case 40, a connection part attachment port 40e, which is an opening to which the connection part 50 is attached, is formed.
This connection part attachment port 40e forms a notch part in the center of the rear part of the lower case 41 and the upper case 42, respectively, and when the lower case 41 and the upper case 42 are combined vertically, these notch parts are combined. An opening is formed.

次に、ケース４０の一方の側壁には、後述する回転ブラシ６０の一端と嵌め合う駆動部７０の駆動側装着ガイド７３をケース４０の内方に挿入するための略円形状の駆動部装着開口４０ｂが形成されている。
この駆動部装着開口４０ｂは、下ケース４１と上ケース４２の側壁の端に、それぞれ半円形状の切り欠き部を形成し、下ケース４１と上ケース４２が上下に合わさる際に、これらの切り欠き部が合わさることで円形状の開口が形成される。Next, on one side wall of the case 40, a substantially circular drive unit mounting opening for inserting a drive side mounting guide 73 of the drive unit 70 that fits into one end of the rotating brush 60 described later into the inside of the case 40. 40b is formed.
The drive portion mounting opening 40b is formed with semicircular cutouts at the ends of the side walls of the lower case 41 and the upper case 42, respectively, and when the lower case 41 and the upper case 42 are joined together in the vertical direction, A circular opening is formed by combining the notches.

次に、ケース４０の他方の側壁には、後述する回転ブラシ６０を回転ブラシ収納室４０ａに挿入し、回転ブラシ６０の固定側装着ガイド６０ｅを係合する位置である略円形状で部分的に凹形状が形成された回転ブラシ装着開口４０ｃが開口している。
この回転ブラシ装着開口４０ｃは、下ケース４１と上ケース４２の側壁に、それぞれ半円形状及び凹形状が組み合わされた形状の切り欠き部を形成し、下ケース４１と上ケース４２が上下に合わさる際に、これらの切り欠き部が合わさることで形成される。Next, on the other side wall of the case 40, a rotating brush 60 described later is inserted into the rotating brush storage chamber 40a and partially fixed in a substantially circular shape that is a position where the fixed side mounting guide 60e of the rotating brush 60 is engaged. A rotating brush mounting opening 40c having a concave shape is opened.
The rotating brush mounting opening 40c forms notches with a combination of a semicircular shape and a concave shape on the side walls of the lower case 41 and the upper case 42, respectively, so that the lower case 41 and the upper case 42 are aligned vertically. In this case, these cutout portions are formed together.

次に、回転ブラシ装着開口４０ｃ側の回転ブラシ収納室４０ａの端側であって、吸込口４１ａと上下に重ならない位置には、回転ブラシ６０に付着した毛髪等を除去するリング形状である塵埃除去具４３を、このリング形状の周方向に回転自在に収納する塵埃除去具収納室４４が形成されている。
この塵埃除去具４３は、リング部４３ａと、このリング部４３ａから立設する爪部４３ｂを有する。尚、爪部４３ｂの数は、後述する回転ブラシ６０のらせん状の溝６０ｂの数と同数である。また、爪部４３ｂが立設する方向は、リング部４３ａが塵埃除去具収納室４４に取り付けられた状態において、駆動部装着開口４０ｂの方向を向いている。Next, at the end of the rotating brush storage chamber 40a on the rotating brush mounting opening 40c side and at a position that does not overlap vertically with the suction port 41a, the ring-shaped dust that removes hair and the like attached to the rotating brush 60 is removed. A dust removal tool storage chamber 44 is formed for storing the removal tool 43 rotatably in the ring-shaped circumferential direction.
The dust removing tool 43 includes a ring portion 43a and a claw portion 43b standing from the ring portion 43a. Note that the number of the claw portions 43b is the same as the number of spiral grooves 60b of the rotating brush 60 described later. Further, the direction in which the claw portion 43 b stands is directed toward the drive portion mounting opening 40 b in a state where the ring portion 43 a is attached to the dust removing tool storage chamber 44.

次に、塵埃除去具収納室４４は、下ケース４１から立設する半円状の切欠きがそれぞれ形成された３枚のリブ４１ｂ，４１ｃ，４１ｄと、上ケース４２から立設する半円状の切欠きがそれぞれ形成された３枚のリブ４２ｂ，４２ｃ，４２ｄが、下ケース４１と上ケース４２が上下に合わさる際に、これらの切り欠き部が上下に合わさることで形成されている。
尚、回転ブラシ収納室４０ａの下方（下ケース４１側）は、塵埃除去具４３の回転空間を確保する為に、塵埃除去具４３が外れない程度に開口している。Next, the dust removing tool storage chamber 44 has three ribs 41 b, 41 c, 41 d each formed with a semicircular cutout standing from the lower case 41 and a semicircular shape standing from the upper case 42. The three ribs 42b, 42c, and 42d formed with the notches are formed by aligning these notches vertically when the lower case 41 and the upper case 42 are vertically aligned.
In addition, in order to ensure the rotation space of the dust removal tool 43, the downward direction (the lower case 41 side) of the rotating brush storage chamber 40a is opened to such an extent that the dust removal tool 43 cannot be removed.

尚、回転ブラシ収納室４０ａ側と回転ブラシ装着開口４０ｃ側に位置するリブ４１ｂ，４１ｄ，４２ｂ，４２ｄに形成されている半円状の切欠きは、塵埃除去具４３のリング部４３ａの外径より小さい。また、これらのリブの中央に位置するリブ４１ｃ，４２ｃの半円状の切欠きは、リング部４３ａの外径より大きく形成されている。
従って、回転ブラシ収納室４０ａ側と回転ブラシ装着開口４０ｃ側に位置するリブに、左右に挟まれた位置に、塵埃除去具収納室４４が形成されており、上記の大きさの関係により、塵埃除去具４３が収納室から外れることなく保持される。The semicircular notches formed in the ribs 41b, 41d, 42b, and 42d located on the rotating brush storage chamber 40a side and the rotating brush mounting opening 40c side are the outer diameters of the ring portion 43a of the dust removing tool 43. Smaller than. The semicircular cutouts of the ribs 41c and 42c located at the center of these ribs are formed larger than the outer diameter of the ring portion 43a.
Accordingly, the dust removal tool storage chamber 44 is formed at a position sandwiched between the ribs positioned on the rotary brush storage chamber 40a side and the rotary brush mounting opening 40c side. The removal tool 43 is held without being removed from the storage chamber.

更に、リブ４１ｂ，４１ｃ，４１ｄと、リブ４２ｂ，４２ｃ，４２ｄは、それぞれ互いに平行であり、また、床面吸込具Ｓの使用時の進行方向と平行に構成されている。
つまり、塵埃除去具収納室４４は、塵埃除去具４３を床面吸込具Ｓの使用時の進行方向と平行な状態に保持する。
以上説明した、回転ブラシ装着開口４０ｃ、塵埃除去具収納室４４、この塵埃除去具収納室４４に保持される塵埃除去具４３、駆動部装着開口４０ｂの各中心は、略同軸方向に床面吸込具Ｓ内部に並んでいる。Furthermore, the ribs 41b, 41c, 41d and the ribs 42b, 42c, 42d are parallel to each other, and are configured to be parallel to the traveling direction when the floor suction tool S is used.
That is, the dust remover storage chamber 44 holds the dust remover 43 in a state parallel to the traveling direction when the floor suction tool S is used.
The centers of the rotary brush mounting opening 40c, the dust removing tool storage chamber 44, the dust removing tool 43 held in the dust removing tool storage chamber 44, and the driving unit mounting opening 40b described above are sucked into the floor surface in a substantially coaxial direction. Lined up inside the tool S.

ここで、主に図１４〜図１９を参照して、ケース４０に取り付けられる回転ブラシ６０について説明する。
回転ブラシ６０は、回転ブラシ６０の回転軸となる棒状の軸６０ｇが内部に挿入されている本体軸６０ａの外周に、らせん状の複数の溝６０ｂが形成されていると共に、隣り合う溝の間にらせん状にブラシ６０ｃが回転ブラシ６０の外方向に向かって設けられている。
図において、ブラシ６０ｃは柔軟性のある樹脂などで構成された短冊状のものを用いているが、回転ブラシ６０の外方向に向かって伸びる毛状ものでもよい。Here, the rotating brush 60 attached to the case 40 will be described mainly with reference to FIGS.
The rotating brush 60 has a plurality of spiral grooves 60b formed on the outer periphery of a body shaft 60a into which a rod-shaped shaft 60g serving as a rotating shaft of the rotating brush 60 is inserted, and between the adjacent grooves. A brush 60 c is provided in a spiral shape toward the outer side of the rotating brush 60.
In the figure, the brush 60c is a strip having a flexible resin or the like. However, the brush 60c may be a hair that extends outward from the rotating brush 60.

そして、本体軸６０ａの一方の端には、後述する駆動部７０の駆動側装着ガイド７３が嵌りこみ係合する凹部６０ｄが形成されている。この凹部６０ｄには、軸６０ｇと平行な向きとなる溝６０ｊが形成されている。
この溝６０ｊは、後述する駆動側装着ガイド７３に形成された動力伝達リブ７３ａが、軸６０ｇの軸方向から入り込むことにより係合し、駆動側装着ガイド７３の回転に対して凹部６０ｄの空回りを防止する為の回り止め構造である。
尚、凹部６０ｄ側の軸６０ｇの先端側には、本体軸６０ａから軸６０ｇが抜けないようにするために、抜け止め６０ｗが設けられている。A recess 60d is formed at one end of the main body shaft 60a, into which a driving side mounting guide 73 of the driving unit 70 described later is fitted and engaged. A groove 60j that is parallel to the shaft 60g is formed in the recess 60d.
The groove 60j is engaged when a power transmission rib 73a formed in a driving side mounting guide 73, which will be described later, enters from the axial direction of the shaft 60g, and rotates around the recess 60d with respect to the rotation of the driving side mounting guide 73. It is a detent structure to prevent it.
A stopper 60w is provided on the tip end side of the shaft 60g on the recess 60d side so that the shaft 60g does not come off from the main body shaft 60a.

次に、本体軸６０ａの他方の端に形成された凹部６０ｉには、固定側装着ガイド受部６０ｈが、内部に軸６０ｇを貫通した状態で、圧入により固定されている。
そして、この固定側装着ガイド受部６０ｈの本体軸６０ａが位置する反対側には、内部に軸受６０ｒを有する固定側装着ガイド６０ｅが、軸受６０ｒが軸６０ｇを軸支した状態で、軸６０ｇに対して回転自在に設けられている。Next, in the recess 60i formed at the other end of the main body shaft 60a, a fixed-side mounting guide receiving portion 60h is fixed by press-fitting with the shaft 60g penetrating inside.
Then, on the opposite side of the fixed-side mounting guide receiving portion 60h where the main body shaft 60a is located, a fixed-side mounting guide 60e having a bearing 60r therein is attached to the shaft 60g with the bearing 60r pivotally supporting the shaft 60g. On the other hand, it is provided rotatably.

尚、固定側装着ガイド受部６０ｈと軸受６０ｒの間には、リング形状の２つの潤滑板６０ｋがリング開口に軸６０ｇを通した状態で設けられている。この潤滑板６０ｋは、回転ブラシ６０が回転する際に、ケース４０に固定されている固定側装着ガイド６０ｅと、本体軸６０ａと共に回転する固定側装着ガイド受部６０ｈの接触抵抗を減らし、効率よく本体軸６０ａを回転させるためのものである。
また、固定側装着ガイド６０ｅが、軸６０ｇから抜けないように、固定側装着ガイド６０ｅから見て、固定側装着ガイド６０ｅを貫通する軸６０ｇの先端側に、抜け止め６０ｍが設けられている。Note that two ring-shaped lubricating plates 60k are provided between the fixed-side mounting guide receiving portion 60h and the bearing 60r with the shaft 60g passing through the ring opening. This lubricating plate 60k reduces the contact resistance between the fixed side mounting guide 60e fixed to the case 40 and the fixed side mounting guide receiving portion 60h that rotates together with the main body shaft 60a when the rotating brush 60 rotates, and efficiently. This is for rotating the main body shaft 60a.
Further, a stopper 60m is provided on the distal end side of the shaft 60g penetrating the fixed side mounting guide 60e as viewed from the fixed side mounting guide 60e so that the fixed side mounting guide 60e does not come off from the shaft 60g.

この抜け止め６０ｍは、固定側装着ガイド６０ｅと固定側装着ガイド受部６０ｈの軸６０ｇの軸方向（図面左右方向）の間に、クリアランスが形成されるように軸６０ｇに取付けられている。このように構成することにより、ケース４０や回転ブラシ６０の大きさに製造誤差などによりバラつきが生じても、各部を組みたて可能で、かつ、回転ブラシ６０がスムーズに回転できるように構成されている。
また、上記のように形成されたクリアランスに弾性体（例えば、バネ、ウエーブワッシャー）を介在させることで、上記の効果を奏すると共に、クリアランス内部に糸くずや毛髪などの塵埃の侵入を防止することができる。The retainer 60m is attached to the shaft 60g so that a clearance is formed between the fixed side mounting guide 60e and the axial direction (left and right direction in the drawing) of the shaft 60g of the fixed side mounting guide receiving portion 60h. By configuring in this way, even if the size of the case 40 or the rotating brush 60 varies due to manufacturing errors or the like, it is possible to assemble each part and to rotate the rotating brush 60 smoothly. ing.
In addition, by providing an elastic body (for example, a spring or a wave washer) in the clearance formed as described above, the above effects can be achieved and dust such as lint and hair can be prevented from entering the clearance. Can do.

次に、この抜け止め６０ｍを被うように固定側装着ガイド６０ｅにカバー６０ｎが圧入により固定されている。
このカバー６０ｎには、開口である透孔６０ｔが形成されている。この透孔６０ｔが形成されていることで、回転ブラシ６０を水で洗浄した後に、カバー６０ｎと固定側装着ガイド６０ｅの隙間に進入した水を外部に排出可能であると共に、軸受６０ｒで生じる熱を回転ブラシ６０の外部に放出し、軸受６０ｒを冷却することができる。Next, a cover 60n is fixed to the fixed side mounting guide 60e by press fitting so as to cover the retaining 60m.
The cover 60n is formed with a through hole 60t that is an opening. By forming the through hole 60t, after the rotary brush 60 is washed with water, the water that has entered the gap between the cover 60n and the fixed side mounting guide 60e can be discharged to the outside, and the heat generated in the bearing 60r. Can be discharged to the outside of the rotating brush 60 to cool the bearing 60r.

特に、固定側装着ガイド６０ｅにブラシ室と連通する透孔を形成することで、床面吸込具Ｓを使用する際に、透孔６０ｔからブラシ室へと流れる気流を形成することができ、より軸受６０ｒの冷却を促進することが可能となる。
また、回転ブラシ６０の端となるカバー６０ｎに***部６０ｖを形成することで、床面吸込具Ｓを使用する際に受ける衝撃力を緩和や、***部６０ｖを曲面とすることで、家具や壁などとの引っかかりを軽減することができる。In particular, by forming a through hole communicating with the brush chamber in the fixed side mounting guide 60e, when using the floor suction tool S, an air flow flowing from the through hole 60t to the brush chamber can be formed. It becomes possible to promote cooling of the bearing 60r.
Further, by forming the raised portion 60v on the cover 60n that is the end of the rotating brush 60, the impact force received when the floor suction tool S is used can be reduced, and the raised portion 60v can be curved so that furniture or You can reduce the catching on the wall.

次に、固定側装着ガイド６０ｅには、固定側装着ガイド６０ｅと共に回転可能で、周方向に突出した凸部６０ｆが形成されている。
固定側装着ガイド６０ｅは、回転ブラシ装着開口４０ｃに装着する際、凸部６０ｆを回転ブラシ装着開口４０ｃの凹形状の部分から挿入し、係止片６０ｓを固定側装着ガイド６０ｅに対して回転させることで、凹形状の部分と係止片６０ｓの左右の位置がずれて回転ブラシ装着開口４０ｃ側に係合する。Next, the fixed side mounting guide 60e is formed with a convex portion 60f that is rotatable together with the fixed side mounting guide 60e and protrudes in the circumferential direction.
When the fixed side mounting guide 60e is mounted in the rotating brush mounting opening 40c, the convex portion 60f is inserted from the concave portion of the rotating brush mounting opening 40c, and the locking piece 60s is rotated with respect to the fixed side mounting guide 60e. As a result, the left and right positions of the concave portion and the locking piece 60s are shifted and engaged with the rotary brush mounting opening 40c.

これにより、固定側装着ガイド６０ｅが回転ブラシ装着開口４０ｃに固定されて、抜けなくなるように構成されている。
尚、固定側装着ガイド６０ｅは、本体軸６０ａに対して回転自在に設けられているので、固定側装着ガイド６０ｅが回転ブラシ装着開口４０ｃに固定されても、本体軸６０ａは回転ブラシ収納室４０ａに回転可能に収納される。As a result, the fixed side mounting guide 60e is fixed to the rotating brush mounting opening 40c so that it cannot be removed.
The fixed-side mounting guide 60e is rotatably provided with respect to the main body shaft 60a. Therefore, even if the fixed-side mounting guide 60e is fixed to the rotating brush mounting opening 40c, the main body shaft 60a remains in the rotating brush storage chamber 40a. It is stored in a rotatable manner.

次に、主に図２０〜図２３を参照して、回転ブラシ６０の回転駆動力を発生させる駆動部７０について説明する。
駆動部７０は、外郭を構成するタービンケース７１と、タービンケース７１の内部に設けられた気流により回転するタービン７２と、回転ブラシ６０の一端に装着しタービン７２の回転駆動力を伝える駆動側装着ガイド７３と、このタービンの回転駆動力を駆動側装着ガイド７３に伝達する駆動力伝達手段であるベルト７４と、この駆動部７０を床面吸込具Ｓに取り付けた際に床面吸込具Ｓからの脱落を防止する為の係止部７５から構成されている。Next, the drive unit 70 that generates the rotational driving force of the rotary brush 60 will be described mainly with reference to FIGS.
The drive unit 70 includes a turbine case 71 constituting an outer shell, a turbine 72 that is rotated by an airflow provided inside the turbine case 71, and a drive-side attachment that is attached to one end of the rotary brush 60 and transmits the rotational driving force of the turbine 72. The guide 73, the belt 74 which is a driving force transmitting means for transmitting the rotational driving force of the turbine to the driving side mounting guide 73, and the floor suction device S when the drive unit 70 is attached to the floor suction device S. It is comprised from the latching | locking part 75 for preventing omission.

タービンケース７１は、一方の側方には、タービン７２を回転させる為の気流を導入する導入口７１ａが形成され、他方の側方には、タービン７２を通過した気流が外部に排気される排気口７１ｂと、タービンケース７１内部から駆動側装着ガイド７３が突出するガイド開口７１ｃが形成されている。尚、排気口７１ｂは、筒形状に形成されたタービンケース７１の筒部７１ｄの先端に開口している。
そして、タービンケース７１の内部空間には、導入口７１ａと排気口７１ｂの間に、タービン７２が回転自在に軸支されている。尚、タービン７２には、同軸にタービン用プーリー７２ａが取付けられている。In the turbine case 71, an inlet 71a for introducing an airflow for rotating the turbine 72 is formed on one side, and the airflow that has passed through the turbine 72 is exhausted to the outside on the other side. A port 71b and a guide opening 71c from which the drive side mounting guide 73 protrudes from the inside of the turbine case 71 are formed. In addition, the exhaust port 71b is opened at the front-end | tip of the cylinder part 71d of the turbine case 71 formed in cylinder shape.
In the internal space of the turbine case 71, a turbine 72 is rotatably supported between an introduction port 71a and an exhaust port 71b. A turbine pulley 72 a is coaxially attached to the turbine 72.

次に、駆動側装着ガイド７３は、略円筒形状の基部７３ｂ、この基部７３ｂの回転中心を基準に９０度間隔で、動力伝達リブ７３ａが形成されている。この動力伝達リブ７３ａは、各部を組みつけた際に、軸６０ｇの軸方向に対して垂直方向から見た形状が、円弧形状（又は弓形）であり、各部が組み付けられた際に軸６０ｇに対して平行になるように、基部７３ｂから径方向に突出している。
そして、駆動側装着ガイド７３は、同軸にガイド用プーリー７３ｃが設けられている。Next, the drive side mounting guide 73 has a substantially cylindrical base 73b and power transmission ribs 73a formed at intervals of 90 degrees with respect to the rotation center of the base 73b. The power transmission rib 73a has an arcuate shape (or arcuate shape) viewed from the direction perpendicular to the axial direction of the shaft 60g when the respective portions are assembled, and is attached to the shaft 60g when the respective portions are assembled. It protrudes in the radial direction from the base 73b so as to be parallel to the base 73b.
The drive side mounting guide 73 is provided with a guide pulley 73c coaxially.

また、駆動側装着ガイド７３は、動力伝達リブ７３ａが、タービンケース７１の外側に位置し、ガイド用プーリー７３ｃがタービンケース７１の内部に位置するように、ガイド開口７１ｃに回転自在に軸支されている。
更に、タービンケース７１の内部のタービン用プーリー７２ａとガイド用プーリー７３ｃの間には、プーリー７６が設けられている。このプーリー７６は、タービン７２で発生した回転駆動力を適切な回転速度・トルクに変換して駆動側装着ガイド７３に伝達する為のものである。The drive side mounting guide 73 is rotatably supported by the guide opening 71c so that the power transmission rib 73a is located outside the turbine case 71 and the guide pulley 73c is located inside the turbine case 71. ing.
Further, a pulley 76 is provided between the turbine pulley 72 a and the guide pulley 73 c inside the turbine case 71. The pulley 76 is for converting the rotational driving force generated in the turbine 72 into an appropriate rotational speed / torque and transmitting it to the drive side mounting guide 73.

そして、タービン用プーリー７２ａとプーリー７６、プーリー７６とガイド用プーリー７３ｃをそれぞれベルト７４ａ、７４ｂにより繋ぐことで、タービン７２の回転駆動力を駆動側装着ガイド７３に伝達可能に構成されている。
尚、本実施の形態のように、タービン用プーリー７２ａとガイド用プーリー７３ｃとの間に、減速用のプーリーを介在さることで、駆動側装着ガイド７３に伝達される回転駆動力を調整しているが、タービン用プーリー７２ａとガイド用プーリー７３ｃを直接ベルトで繋いでもよい。The turbine pulley 72 a and the pulley 76, and the pulley 76 and the guide pulley 73 c are connected by belts 74 a and 74 b, respectively, so that the rotational driving force of the turbine 72 can be transmitted to the drive side mounting guide 73.
As in this embodiment, the rotational driving force transmitted to the drive side mounting guide 73 is adjusted by interposing a deceleration pulley between the turbine pulley 72a and the guide pulley 73c. However, the turbine pulley 72a and the guide pulley 73c may be directly connected by a belt.

以上のように構成された駆動部７０は、次のように床面吸込具Ｓに取り付けられる。
主に図１９，図２３を参照すると、まず、上ケース４２と上カバー４６により形成された連通開口４６ａには、タービンケース７１の筒部７１ｄが挿入されると共に、駆動部装着開口４０ｂには、タービンケース７１に設けられた駆動側装着ガイド７３が挿入される。
そして、駆動部７０に設けられた係止部７５が、床面吸込具Ｓの係合開口４６ｂに係止することにより、駆動部７０が床面吸込具Ｓに確実に取り付けられる。
このように、床面吸込具Ｓにおいて、駆動部７０は床面吸込具Ｓの一方の側部、つまり、長手方向（左右方向）中央からずれた位置に設けられるので、極力小型に構成されている他方の側部に対して、重量が重くなり、左右の重量バランスが偏る構成となる。The drive unit 70 configured as described above is attached to the floor suction tool S as follows.
Referring mainly to FIGS. 19 and 23, first, the cylinder portion 71d of the turbine case 71 is inserted into the communication opening 46a formed by the upper case 42 and the upper cover 46, and the drive portion mounting opening 40b is inserted into the driving portion mounting opening 40b. The drive side mounting guide 73 provided in the turbine case 71 is inserted.
And the latching | locking part 75 provided in the drive part 70 latches to the engagement opening 46b of the floor surface suction tool S, and the drive part 70 is attached to the floor surface suction tool S reliably.
In this way, in the floor suction tool S, the drive unit 70 is provided at one side of the floor suction tool S, that is, at a position shifted from the center in the longitudinal direction (left-right direction), and thus is configured as small as possible. The other side portion is heavier and the left and right weight balance is biased.

以上のように駆動部７０が床面吸込具Ｓに取り付けられることにより、回転ブラシ収納室４０ａと風路Ｆと駆動部の導入口７１ａと排気口７１ｂが連通するので、駆動部７０に対しても電動送風機が発生する吸引力が生じることで、タービン７２を回転可能な気流を得ることができる。
つまり、電動送風機が起こす吸引力により、導入口７１ａから流入した気流は、タービン７０を回転駆動し、排気口７１ｂから排出され、この排出された気流は上ケース４２と上カバー４６により形成された風路Ｆを流下した後、上ケース４２の前開口から回転ブラシ収納室４０ａへと流入し、吸込口４１ａから流入した気流と共に、集塵風路を通り接続部５０へと流下する。Since the drive unit 70 is attached to the floor suction tool S as described above, the rotary brush storage chamber 40a, the air passage F, the drive unit inlet 71a, and the exhaust port 71b communicate with each other. In addition, since the suction force generated by the electric blower is generated, an airflow capable of rotating the turbine 72 can be obtained.
That is, due to the suction force generated by the electric blower, the airflow flowing in from the introduction port 71a rotates the turbine 70 and is discharged from the exhaust port 71b. The discharged airflow is formed by the upper case 42 and the upper cover 46. After flowing down the air path F, the air flows into the rotating brush storage chamber 40a from the front opening of the upper case 42, and flows down to the connecting portion 50 through the dust collecting air path together with the airflow flowing in from the suction port 41a.

次に、ケース４０の内部からの回転ブラシ６０の着脱について説明する。
（１）回転ブラシ６０の取り付け
まず、回転ブラシ６０は、凹部６０ｄが形成されている側の端から、回転ブラシ装着開口４０ｃに挿入される。
この時、塵埃除去具４３のリング部４３ａの内部開口に、回転ブラシ６０が挿入されると共に、回転ブラシ６０の複数の溝６０ｂに、リング部４３ａの爪部４３ｂがそれぞれ嵌り込んだ状態（爪部４３ｂが溝６０ｂにガイドされた状態）となる。
尚、回転ブラシ６０が、リング部４３ａ内に挿入されるとき、ブラシ６０ｃはリング部４３ａの内を折り曲がりながら通過し、駆動側装着ガイド７３方向に進む。Next, attachment / detachment of the rotating brush 60 from the inside of the case 40 will be described.
(1) Attaching the rotating brush 60 First, the rotating brush 60 is inserted into the rotating brush mounting opening 40c from the end on the side where the recess 60d is formed.
At this time, the rotating brush 60 is inserted into the internal opening of the ring portion 43a of the dust removing tool 43, and the claw portions 43b of the ring portion 43a are fitted in the plurality of grooves 60b of the rotating brush 60 (nail The portion 43b is guided by the groove 60b).
When the rotating brush 60 is inserted into the ring portion 43a, the brush 60c passes through the ring portion 43a while being bent, and proceeds toward the drive side mounting guide 73.

そして、回転ブラシ６０が駆動側装着ガイド７３に向けて、更に挿入されると、爪部４３ｂは回転ブラシ６０に接しながら、らせん状に形成された溝６０ｂに倣って、回転ブラシ６０の挿入動作に逆らわず、塵埃除去具収納室４４内部で回転する。
尚、爪部４３ｂは、駆動部装着開口４０ｂが位置する方向（ケース４０の内方）に先端を向けて形成されているので、回転ブラシ６０を回転ブラシ収納室４０ａに装着する際に、大きな抵抗とならない。When the rotary brush 60 is further inserted toward the drive side mounting guide 73, the claw portion 43b is in contact with the rotary brush 60 and follows the spirally formed groove 60b to insert the rotary brush 60. Without rotating against the dust removal tool storage chamber 44.
Since the claw portion 43b is formed with its tip directed in the direction in which the drive portion mounting opening 40b is located (inward of the case 40), the claw portion 43b is large when the rotating brush 60 is mounted in the rotating brush storage chamber 40a. Does not become resistance.

次に、回転ブラシ６０が駆動部７０の駆動側装着ガイド７３の位置まで挿入されることで、凹部６０ｄに駆動側装着ガイド７３が嵌り込む。このとき、動力伝達リブ７３ａは、溝６０ｊに軸方向から入り込み、溝６０ｊにおいて、駆動側装着ガイド７３の回転駆動方向に保持されることで、駆動側装着ガイド７３の凹部６０ｄにおける空回りを防止する。 また、動力伝達リブ７３ａが溝６０ｊに軸方向から入り込み際に、動力伝達リブ７３ａが円弧形状であることから、溝６０ｊを形成する壁面に対して引っかかりにくく、効率よく装着することができる。   Next, when the rotating brush 60 is inserted to the position of the driving side mounting guide 73 of the driving unit 70, the driving side mounting guide 73 is fitted into the recess 60d. At this time, the power transmission rib 73a enters the groove 60j from the axial direction, and is held in the rotational driving direction of the driving side mounting guide 73 in the groove 60j, thereby preventing idle rotation in the recess 60d of the driving side mounting guide 73. . Further, when the power transmission rib 73a enters the groove 60j from the axial direction, since the power transmission rib 73a has an arc shape, the power transmission rib 73a is not easily caught on the wall surface forming the groove 60j and can be efficiently mounted.

そして、凹部６０ｄに駆動側装着ガイド７３が嵌り込んだ状態において、固定側装着ガイド６０ｅの凸部６０ｆを回転ブラシ装着開口４０ｃの凹形状の部分から挿入し、固定側装着ガイド６０ｅを回転させることで、固定側装着ガイド６０ｅが回転ブラシ装着開口４０ｃに固定されて抜けなくなり、ケース４０からの回転ブラシ６０の脱落が防止される。
これで回転ブラシ６０は、回転ブラシ収納室４０ａに正しく取り付けられる。Then, in a state where the driving side mounting guide 73 is fitted in the concave portion 60d, the convex portion 60f of the fixed side mounting guide 60e is inserted from the concave portion of the rotating brush mounting opening 40c, and the fixed side mounting guide 60e is rotated. Thus, the fixed side mounting guide 60e is fixed to the rotary brush mounting opening 40c and cannot be removed, and the rotary brush 60 is prevented from falling off from the case 40.
Thus, the rotating brush 60 is correctly attached to the rotating brush storage chamber 40a.

尚、回転ブラシ６０が、回転ブラシ収納室４０ａに取り付けられた状態において、爪部４３ｂは回転ブラシ６０の溝６０ｂに倣った状態で保持され、回転ブラシ６０と共に回転駆動する。このように、爪部４３ｂが溝６０ｂに倣った状態で保持されれば、回転ブラシ６０を床面吸込具Ｓから抜くときに、あらためて爪部４３ｂと溝６０ｂの位置を合わせる必要がない。   In the state where the rotating brush 60 is attached to the rotating brush storage chamber 40 a, the claw portion 43 b is held in a state following the groove 60 b of the rotating brush 60 and is rotated together with the rotating brush 60. Thus, if the nail | claw part 43b is hold | maintained in the state which followed the groove | channel 60b, when removing the rotary brush 60 from the floor surface suction tool S, it is not necessary to align the position of the nail | claw part 43b and the groove | channel 60b anew.

（２）回転ブラシ６０の取外しについて
まず、固定側装着ガイド６０ｅを回転させ、回転ブラシ装着開口４０ｃの凹形状と位置を合わせ、回転ブラシ装着開口４０ｃと固定側装着ガイド６０ｅの固定を解除し、固定側装着ガイド６０ｅを引くことで、回転ブラシ装着開口４０ｃから回転ブラシ６０を引き抜くことができる。
回転ブラシ６０が床面吸込具Ｓから引き抜かれ始めると、爪部４３ｂがらせん状に形成された溝６０ｂに倣って、回転ブラシ６０の引き抜き動作に逆らわず、塵埃除去具収納室４４の内部で回転する。(2) Removal of the rotating brush 60 First, the fixed side mounting guide 60e is rotated, the concave shape of the rotating brush mounting opening 40c is aligned with the position, and the fixing of the rotating brush mounting opening 40c and the fixed side mounting guide 60e is released. By pulling the fixed side mounting guide 60e, the rotating brush 60 can be pulled out from the rotating brush mounting opening 40c.
When the rotary brush 60 starts to be pulled out from the floor suction tool S, the claw portion 43b follows the spirally formed groove 60b, and does not oppose the pulling operation of the rotary brush 60, and inside the dust removing tool storage chamber 44. Rotate.

この時、爪部４３ｂが溝６０ｂに倣うことにより、回転ブラシ６０の周囲に絡みつく髪の毛や糸くずのような塵埃を軸やブラシから剥ぎ取る。そして、回転ブラシ６０が塵埃除去具４３のリング部４３ａを通過するときに、回転ブラシ６０の表面から塵埃がこそぎとられる。   At this time, the claw portion 43b follows the groove 60b, so that dust such as hair and lint entangled around the rotary brush 60 is peeled off from the shaft and the brush. When the rotating brush 60 passes through the ring portion 43 a of the dust removing tool 43, dust is scraped from the surface of the rotating brush 60.

以上のように、駆動側装着ガイド７３の動力伝達リブ７３ａと凹部６０ｄに溝６０ｊを形成することにより、両部材を容易に着脱できるように構成できる。
また、動力伝達リブ７３ａの外形状が円形状（弓形）なので、回転ブラシ６０が駆動側装着ガイド７３に対して斜めになっても、溝６０ｊの内壁面（凹部６０ｄの内壁面）に動力伝達リブ７３ａが、径方向に接触することが無い（強く接することが無い）。言い換えると、動力伝達リブ７３ａは回転ブラシ６０が斜めになった状態において、溝６０ｊと径方向に強く接触しない逃げ形状となっている。
つまり、動力伝達リブ７３ａと溝６０ｊの係合関係を自在継ぎ手構造（ユニバーサルジョイント）に構成されている。As described above, by forming the groove 60j in the power transmission rib 73a and the recess 60d of the drive side mounting guide 73, both members can be easily attached and detached.
Further, since the outer shape of the power transmission rib 73a is circular (bowed), even if the rotary brush 60 is inclined with respect to the drive side mounting guide 73, power is transmitted to the inner wall surface of the groove 60j (inner wall surface of the recess 60d). The rib 73a does not contact in the radial direction (does not contact strongly). In other words, the power transmission rib 73a has a relief shape that does not make strong contact with the groove 60j in the radial direction when the rotary brush 60 is inclined.
That is, the engagement relationship between the power transmission rib 73a and the groove 60j is configured as a universal joint structure (universal joint).

これにより、床面吸込具Ｓを構成する各部の大きさの製造誤差や、回転ブラシ６０を取付ける際の不手際等により、回転ブラシ６０が軸受係止凹部に対して斜めに取付けられ場合や、清掃時の床面の凸部を回転ブラシ６０が乗り越える際などに、回転ブラシ６０が駆動側装着ガイド７３に対して斜めになっても、動力伝達リブ７３ａと溝６０ｊが、駆動力伝達のための回転を阻害することなく回転方向に係合するので、駆動側装着ガイド７３からの回転駆動力を回転ブラシ６０に確実に伝達することが可能である。   Thereby, due to manufacturing errors in the size of each part constituting the floor surface suction tool S, inconvenience when attaching the rotating brush 60, or the like, the rotating brush 60 is attached obliquely to the bearing locking recess, or cleaning is performed. Even when the rotary brush 60 gets over the drive side mounting guide 73 when the rotary brush 60 gets over the convex part of the floor at the time, the power transmission rib 73a and the groove 60j are used for driving force transmission. Since it engages in the rotation direction without impeding the rotation, it is possible to reliably transmit the rotational driving force from the driving side mounting guide 73 to the rotating brush 60.

また、回転ブラシ６０をケース４０から抜きながら回転ブラシ６０に付着した塵埃を取ることができる。特に、床面吸込具Ｓの吸込口を上方に向けて、回転ブラシ６０を抜き取れば、回転ブラシ６０からとられた塵埃は、床面吸込具Ｓの内部に落ちることから、作業者の手や周囲を汚すことがない。   Further, dust attached to the rotating brush 60 can be removed while removing the rotating brush 60 from the case 40. In particular, if the rotary brush 60 is pulled out with the suction port of the floor surface suction tool S facing upward, dust taken from the rotary brush 60 falls into the floor surface suction tool S. And does not pollute the surroundings.

また、回転ブラシ６０を取り付けるときも、取外すときも、塵埃除去具４３が溝６０ｂの形状に倣って回転するので、塵埃除去具４３が設けられたことによる回転ブラシ６０着脱時の抵抗を最小限にすることが可能である。
更に、塵埃除去具４３が溝６０ｂの形状に倣って回転するので、溝６０ｂの形状を直線形状の形態に限らず、溝６０ｂの形状をらせん形状等の曲線により構成することが可能である。
また、固定側装着ガイド６０ｅの軸６０ｇから離れた位置には、径方向の突出するつまみ部６０ｕが形成されている。これにより、毛髪や糸くずなどが固定側装着ガイド６０ｅに巻きついても、固定側装着ガイド６０ｅの取外し動作をより少ない力で行うことが可能となるIn addition, since the dust removing tool 43 rotates following the shape of the groove 60b when attaching or removing the rotating brush 60, the resistance when the rotating brush 60 is attached / detached due to the provision of the dust removing tool 43 is minimized. It is possible to
Furthermore, since the dust removal tool 43 rotates following the shape of the groove 60b, the shape of the groove 60b is not limited to a linear shape, and the shape of the groove 60b can be configured by a curved line such as a spiral shape.
Further, a knob portion 60u protruding in the radial direction is formed at a position away from the shaft 60g of the fixed side mounting guide 60e. As a result, even if hair, lint, or the like wraps around the fixed-side mounting guide 60e, the removal operation of the fixed-side mounting guide 60e can be performed with less force.

以上、回転ブラシ６０の着脱について説明したが、図１８において、塵埃除去具４３とブラシ６０ｃの関係を解りやすく説明する為、ブラシ６０ｃと塵埃除去具４３が重なる部分については、ブラシ６０ｃを省略して表現した。
実際の形態は、塵埃除去具４３内を回転ブラシ６０が移動する際、ブラシ６０ｃはリング部４３ａの内部を折れ曲がった状態で通過する。The attachment / detachment of the rotary brush 60 has been described above.

Further, the front screw boss receiver 40d used for assembling the lower case 41 and the upper case 42 has an outer side of a traveling roller provided on the front side of the lower case 41 so as not to block the airflow in the rotating brush storage chamber 40a. That is, it is arranged outside the rotating brush storage chamber 40a.

次に、主に図８，図１９を参照して、後述する駆動部７０内に設けられたタービン７２を回転させ、駆動部から排気された気流の風路Ｆについて説明する。
上ケース４２には、上ケース４２の上面と所定の間隔を空けて、上ケース４２の上面及び前側を覆う上カバー４６が設けられている。そして、上ケース４２の前方には、長手方向に前開口部４２ａが形成されており、上ケース４２と上カバー４６により囲まれた空間Ｋと回転ブラシ収納室４０ａとが連通している。Next, with reference mainly to FIGS. 8 and 19, the air path F of the airflow exhausted from the drive unit by rotating the turbine 72 provided in the drive unit 70 described later will be described.
The upper case 42 is provided with an upper cover 46 that covers the upper surface and the front side of the upper case 42 with a predetermined distance from the upper surface of the upper case 42. A front opening 42a is formed in the longitudinal direction in front of the upper case 42, and the space K surrounded by the upper case 42 and the upper cover 46 communicates with the rotary brush storage chamber 40a.

また、上ケース４２の駆動部装着開口４０ｂが形成されている側の側面後方には、上ケース４２と上カバーが合わさることで、駆動部７０の排気風路と連通する連通開口４６ａが形成されている。
以上のように各部を構成することで、上ケース４２と上カバーに挟まれた空間Ｋと、連通開口４６ａと、前開口部４２ａにより、駆動部７０からの排気を流下させる風路Ｆが構成される。
この他に、上カバー４６には、駆動部７０を床面吸込具Ｓに取り付ける時に駆動部７０の係止部７５と係合する係合開口４６ｂが形成されている。The upper case 42 and the upper cover are combined with each other to form a communication opening 46a that communicates with the exhaust air passage of the drive unit 70 on the rear side of the upper case 42 on the side where the drive unit mounting opening 40b is formed. ing.
By configuring each part as described above, the air path F that causes the exhaust from the drive unit 70 to flow down is configured by the space K sandwiched between the upper case 42 and the upper cover, the communication opening 46a, and the front opening 42a. Is done.
In addition, the upper cover 46 is formed with an engagement opening 46 b that engages with the locking portion 75 of the drive unit 70 when the drive unit 70 is attached to the floor suction tool S.

次に、主に図１１〜図１２を参照して、接続部５０について説明する。
接続部５０は、吸込筒５１と接続管５２から構成されている。吸込筒５１は、一端（第１の端５１ａ）をケース４０の後部中央（後部長手方向中央）に形成された接続部取付口４１ｅに、取付け位置を中心にケース４０に対して、前後に回動自在に連結されている。 そして、吸込筒５１の他端（第２の端５１ｂ）の外形状は円筒形状に形成されており、第２の端５１ｂと縁から所定間隔空けた位置に吸込筒５１外周に沿ったフランジ部５１ｃが形成されている。Next, the connection part 50 is demonstrated mainly with reference to FIGS.
The connection part 50 is composed of a suction cylinder 51 and a connection pipe 52. The suction cylinder 51 has one end (first end 51a) at a connection portion attachment port 41e formed at the rear center (rear longitudinal direction center) of the case 40, and back and forth with respect to the case 40 around the attachment position. It is pivotally connected. The outer shape of the other end (second end 51b) of the suction tube 51 is formed in a cylindrical shape, and a flange portion along the outer periphery of the suction tube 51 at a position spaced from the second end 51b by a predetermined distance. 51c is formed.

この第２のフランジは第１のフランジより直径が小さく、また、第２のフランジは、第１のフランジが形成されている位置より、吸込筒５１の端側に位置している。
また、フランジ部５１ｃと第２の端５１ｂの縁の間には、吸込筒５１の外周に沿った環状の溝部５１ｄが形成されている。The diameter of the second flange is smaller than that of the first flange, and the second flange is located closer to the end side of the suction cylinder 51 than the position where the first flange is formed.
An annular groove 51d is formed between the flange 51c and the edge of the second end 51b along the outer periphery of the suction cylinder 51.

次に、接続管５２は、内部に円筒形状の空間を有する管状で、その一端には、延長管３０やホース２０と接続するための接続管接続部５２ａが、他端には、接続管接続部５２ａの中心軸に対し傾いて開口した吸込筒５１と連結するための接続管連結部５２ｂが形成されている。
この接続管連結部５２ｂは、円筒形状に形成されており、接続管連結部５２ｂの開口の直径は、吸込筒５１の第２の端５１ｂの直径より大きく、フランジ部５１ｃの直径よりも小さく構成されている。そして、接続管連結部５２ｂの外周面には、２つの透孔が開口している。
尚、接続管連結部５２ｂの上面に形成された透孔５２ｃは、上方を接続管５２にネジ止め５３ａなどにより取り付けられるカバーにより覆われる。Next, the connection pipe 52 is a tube having a cylindrical space inside, a connection pipe connection portion 52a for connecting to the extension pipe 30 and the hose 20 at one end, and a connection pipe connection at the other end. A connecting pipe connecting part 52b for connecting to the suction cylinder 51 which is inclined and opened with respect to the central axis of the part 52a is formed.
The connecting pipe connecting portion 52b is formed in a cylindrical shape, and the diameter of the opening of the connecting pipe connecting portion 52b is larger than the diameter of the second end 51b of the suction cylinder 51 and smaller than the diameter of the flange portion 51c. Has been. And two through-holes are opened in the outer peripheral surface of the connection pipe connection part 52b.
The through hole 52c formed on the upper surface of the connecting pipe connecting portion 52b is covered with a cover that is attached to the connecting pipe 52 by screws 53a or the like.

以上のように構成された吸込筒５１と接続管５２は、次のように連結される。
まず、接続管５２の開口がある接続管連結部５２ｂに、吸込筒５１の第２の端５１ｂを挿入する。つまり、吸込筒５１と接続管５２は、前後の位置関係に連結される。
この時、第２の端５１ｂ側の吸込筒５１の直径は、接続管連結部５２ｂの開口直径より小さいので、接続管５２の内部に入り込と共に、接続管５２と吸込筒５１の間には、吸込筒５１に対して接続管５２が連結位置中心に回動可能（つまり、吸込筒５１に対して接続管５２が左右に動くことが可能）なクリアランスが介在する。
尚、本願でいうクリアランスとは、両部材間に隙間が開いていること、及び、吸込筒５１に対して接続管５２が回動可能な程度の接触状態も含む。The suction cylinder 51 and the connecting pipe 52 configured as described above are connected as follows.
First, the 2nd end 51b of the suction pipe | tube 51 is inserted in the connection pipe connection part 52b with the opening of the connection pipe 52. FIG. That is, the suction cylinder 51 and the connection pipe 52 are connected to the front-rear positional relationship.
At this time, since the diameter of the suction cylinder 51 on the second end 51b side is smaller than the opening diameter of the connection pipe connecting portion 52b, the suction pipe 51 enters the inside of the connection pipe 52 and between the connection pipe 52 and the suction cylinder 51. Further, there is a clearance that allows the connection tube 52 to rotate about the coupling position with respect to the suction tube 51 (that is, the connection tube 52 can move to the left and right with respect to the suction tube 51).
The clearance referred to in the present application includes a state in which a gap is opened between the two members and a contact state in which the connection tube 52 is rotatable with respect to the suction tube 51.

また、フランジ部５１ｃの直径は、接続管連結部５２ｂの開口直径より大きいので、接続管５２の接続管連結部５２ｂの端は、フランジ部５１ｃに当接する。
この状態において、接続管連結部５２ｂの外周面に開口する透孔５２ｃに、溝部５１ｄの内部に届く抜け止め部材５４を挿入することにより、吸込筒５１の他端側に形成された環状の溝部５１ｄに、この抜け止め部材５４が入り込み、接続管連結部５２ｂから吸込筒５１が抜けるのを防止する。
従って、上記のように各部が連結されることにより、接続管５２は吸込筒５１に対して脱落することなく回動可能に連結される。Moreover, since the diameter of the flange part 51c is larger than the opening diameter of the connection pipe connection part 52b, the end of the connection pipe connection part 52b of the connection pipe 52 contacts the flange part 51c.
In this state, an annular groove formed on the other end side of the suction cylinder 51 by inserting a retaining member 54 that reaches the inside of the groove 51d into the through hole 52c that opens to the outer peripheral surface of the connection pipe connecting portion 52b. This retaining member 54 enters 51d and prevents the suction tube 51 from coming off from the connecting pipe connecting portion 52b.
Therefore, by connecting the respective parts as described above, the connecting pipe 52 is rotatably connected to the suction cylinder 51 without dropping off.

次に、主に図１２〜図１３を参照して、被清掃面Ｇに対する床面吸込具Ｓの状態における接続管５２と吸込筒５１の連結状態と、床面吸込具Ｓの状態を説明する。
（１）被清掃面Ｇを清掃している状態（床面吸込具Ｓが被清掃面Ｇ上に乗っている状態）
床用吸込具Ｓで被清掃面Ｇを清掃している場合、床面吸込具Ｓの重量は被清掃面Ｇが支えている。この状態で使用者は、接続管５２に接続された延長管３０などに接続された手元操作部２１ａの把持部２１を握り、床用吸込具Ｓを、被清掃面Ｇ上を前後に動かして清掃を行う。Next, mainly referring to FIGS. 12 to 13, the connection state of the connecting pipe 52 and the suction cylinder 51 in the state of the floor suction tool S with respect to the surface G to be cleaned and the state of the floor suction tool S will be described. .
(1) A state where the surface to be cleaned G is being cleaned (a state where the floor suction tool S is on the surface to be cleaned G)
When the surface to be cleaned G is cleaned with the floor suction tool S, the surface to be cleaned G supports the weight of the floor surface suction tool S. In this state, the user grasps the grip portion 21 of the hand operation portion 21a connected to the extension tube 30 connected to the connection tube 52 and moves the floor suction tool S back and forth on the surface G to be cleaned. Clean.

この時、吸込筒５１がケース４０に対して取付け位置を中心に、前後に回転動作可能に取り付けられているので、使用者が前後に動かす際に、被清掃面上に位置する床面吸込具Ｓのケース４０側と、接続部５０とこの接続部５０取り付けられた延長管側が、スムーズに動作することができる。
つまり、床面吸込具Ｓを前後に動かすことにより、吸込筒５１がケースに対して回動して、延長管３０等と被清掃面Ｇ（ケース４０）のなす角度を変化させて、床面吸込具Ｓを被清掃面Ｇ上から離れることなく動作させることができる。At this time, since the suction cylinder 51 is attached to the case 40 so as to be able to rotate back and forth around the attachment position, the floor surface suction tool located on the surface to be cleaned when the user moves back and forth. The S case 40 side, the connecting portion 50, and the extension pipe side to which the connecting portion 50 is attached can operate smoothly.
That is, by moving the floor suction tool S back and forth, the suction cylinder 51 rotates with respect to the case, and the angle formed between the extension pipe 30 and the surface to be cleaned G (case 40) is changed. The suction tool S can be operated without leaving the surface to be cleaned G.

次に、吸込筒５１と接続管５２の連結位置状態について説明する。
上記のように、床面吸込具Ｓを、被清掃面Ｇ上を前後に動かす場合、吸込筒５１と接続管５２の連結位置には、主に前後方向の力が作用する。
つまり、接続管５２の接続管連結部５２ｂの内周面と５２ｓ、吸込筒５１の第２の端５１ｂ側の外周面５１ｓは、上下に互いに強く接触しないので、接続管５２が吸込筒５１に対して回動可能なクリアランスＣを保つことが可能である。
従って、床面吸込具Ｓが被清掃面Ｇ上にある時は、吸込筒５１に対して接続管５２が左右に回動可能（取り付け方向に対して垂直の面を回動作可能）に保たれる。Next, the connection position state of the suction cylinder 51 and the connection pipe 52 will be described.
As described above, when the floor suction tool S is moved back and forth on the surface to be cleaned G, a force in the front-rear direction mainly acts on the connection position between the suction cylinder 51 and the connection pipe 52.
That is, the inner peripheral surface 52s of the connecting pipe connecting portion 52b of the connecting pipe 52 and the outer peripheral face 51s on the second end 51b side of the suction cylinder 51 do not come into strong contact with each other in the vertical direction. On the other hand, it is possible to maintain a rotatable clearance C.
Therefore, when the floor suction tool S is on the surface to be cleaned G, the connecting pipe 52 can be turned left and right with respect to the suction cylinder 51 (a surface perpendicular to the mounting direction can be rotated). It is.

（２）床面吸込具Ｓが接続部５０側を持って、被清掃面Ｇから持ち上げられた状態
次に、床用吸込具Ｓが、接続部５０側を持って被清掃面Ｇをから持ち上げられた状態を説明する。
まず、ケース４０は自重によって、吸込筒５１に対して、吸込筒５１のケース４０の取付け位置を中心に、前方に傾こうとする力が作用する。上記の力が作用することにより、吸込筒５１が接続管５２に対して、前方に傾く力が作用する。(2) The state where the floor suction tool S is lifted from the surface to be cleaned G with the connecting portion 50 side Next, the floor suction tool S is lifted from the surface to be cleaned G with the connection portion 50 side The state that has been performed will be described.
First, due to its own weight, the case 40 acts on the suction cylinder 51 to tilt forward with the case 40 attached to the suction cylinder 51 as a center. When the above force is applied, the suction cylinder 51 is inclined forward with respect to the connection pipe 52.

この時、接続管５２は吸込筒５１に対して、回動可能となるように両部材の連結位置にクリアランスを設けて連結されているので、上記の作用により接続管連結部５２ｂ内で吸込筒５１が前方へ傾く。
そして、接続管連結部５２ｂの内周面５２ｓと吸込筒５１の外周面５１ｓ、溝部５１ｄの内壁と抜け止め部材５４、及び、接続管５２の端５２ａと吸込筒５１の端５１ｔが、それぞれ互いの面を押圧した状態で接触する。
これにより、吸込筒５１の外周面５１ｓと接続管５２の内周面５２ｓとの間に接触抵抗が生じ、接続管５２に対する吸込筒５１の回動を抑止することができる。At this time, since the connection pipe 52 is connected to the suction cylinder 51 with a clearance at the connecting position of both members so as to be rotatable, the suction cylinder is formed in the connection pipe connecting portion 52b by the above-described action. 51 tilts forward.
The inner peripheral surface 52s of the connecting pipe connecting portion 52b and the outer peripheral surface 51s of the suction cylinder 51, the inner wall of the groove 51d and the retaining member 54, and the end 52a of the connecting pipe 52 and the end 51t of the suction cylinder 51 are mutually connected. The contact is made while pressing the surface of.
Thereby, contact resistance arises between 51s of outer peripheral surfaces of the suction cylinder 51, and 52s of inner peripheral surfaces of the connection pipe 52, and rotation of the suction cylinder 51 with respect to the connection pipe 52 can be suppressed.

従って、回転ブラシ６０の駆動部７０が床面吸込具Ｓの側部に設けられ、左右の重量バランスが不均衡な床面吸込具Ｓを、接続部５２に延長管３０を接続した状態で被清掃面Ｇから持ちあげても、上述した作用により、接続管５２に対する吸込筒５１の回動を抑止することができ、床面吸込具Ｓの傾きを抑止できる。
これにより、床面吸込具Ｓを持ち上げた際に床面吸込具Ｓが右側又は左側（回転ブラシ６０の駆動部が位置する側）に傾いた状態になりにくく、被清掃面Ｇに床面吸込具Ｓを接地させる際に、床面吸込具Ｓが斜めの状態で被清掃面Ｇに接触することがないので、被清掃面Ｇ及び床面吸込具Ｓに強い衝撃を与えることを防止できる。Accordingly, the driving unit 70 of the rotary brush 60 is provided on the side of the floor suction tool S, and the floor suction tool S with an unbalanced left and right weight balance is covered with the extension pipe 30 connected to the connection part 52. Even if it is lifted from the cleaning surface G, the rotation of the suction cylinder 51 with respect to the connection pipe 52 can be suppressed by the above-described action, and the inclination of the floor suction tool S can be suppressed.
Accordingly, when the floor suction tool S is lifted, the floor suction tool S is not easily inclined to the right side or the left side (the side where the driving unit of the rotating brush 60 is located), and the floor surface suction is absorbed into the surface G to be cleaned. When the tool S is grounded, the floor suction tool S does not come into contact with the surface to be cleaned G in an oblique state, so that it is possible to prevent a strong impact from being applied to the surface to be cleaned G and the floor surface suction tool S.

以上のように、この発明に係る床面吸込具は、回転ブラシの床面吸込具本体への取り付け状態や使用時に受ける負荷に関わらず、回転ブラシが安定して回転駆動する電気掃除機に利用できる。   As described above, the floor suction tool according to the present invention is used for an electric vacuum cleaner in which the rotary brush is driven to rotate stably regardless of the mounting state of the rotary brush on the floor suction tool body and the load received during use. it can.
