＜実施形態＞ <Embodiment>

１．電気掃除機ユニット
図１に示すように、電気掃除機ユニットＡは、電気掃除機１及び掃除機支持装置６を備える。
電気掃除機１は、吸込具２、接続パイプ３、掃除機本体４をこの順で備える、いわゆるスティック型（縦型）の掃除機である。電気掃除機１は、吸込具２から接続パイプ３を通って掃除機本体４内に塵埃を吸い込む。なお、電気掃除機１は、図外の電源アダプターと着脱可能に装着されて充電される携帯型である。
電気掃除機１は、接続パイプ３に代えて装着できるブラシ体５を掃除機本体４に備える。
ここで、接続パイプ３の延伸方向（図中の「Ｘ」である）を「筒軸方向」とし、筒軸方向における吸込具２が存在する側を「一端側」とし、掃除機本体４が存在する側を「他端側」とする。吸込具２のヘッド部２１の延伸方向（図中の「Ｙ」である）を「左右方向」とし、当該延伸方向は筒軸方向と直交する。また、左右方向と直交し且つ筒軸方向を含む仮想面において筒軸方向の直交する方向（図中の「Ｚ」である）を「表裏方向」とする。
通常、床面を清掃する際には、吸込具２のヘッド部２１を前後方向に移動させ、ヘッド部２１が位置する側を前側又は表側とし、操作者が位置する側を後側又は裏側とする。また、筒軸方向が上下方向と一致する場合、表裏方向は前後方向と一致することから、表裏方向を、筒軸方向が上下方向と一致しない場合も「前後方向」とする場合もある。
掃除機支持装置６は、接続パイプ３が上下方向と平行なる状態又はこれに近い状態で、電気掃除機１を着脱可能に支持する。掃除機支持装置６は、電気掃除機１の吸込具２を載置する載置台７と、載置台７に載置された電気掃除機１を裏側から支持する支柱８とを備える。ここでは、補助集塵具９が支柱８に出し入れ可能に設けられている。
以下、電気掃除機１及び掃除機支持装置６について説明する。 1. Vacuum Cleaner Unit As shown in FIG. 1, the vacuum cleaner unit A includes a vacuum cleaner 1 and a vacuum cleaner support device 6.
The vacuum cleaner 1 is a so-called stick-type (vertical) vacuum cleaner that includes, in this order, a suction tool 2, a connection pipe 3, and a vacuum cleaner body 4. The vacuum cleaner 1 sucks dust from the suction tool 2 through the connection pipe 3 into the vacuum cleaner body 4. The vacuum cleaner 1 is a portable type that is charged by being detachably attached to a power adapter (not shown).
The electric vacuum cleaner 1 includes a brush body 5 that can be attached to a vacuum cleaner body 4 in place of a connection pipe 3.
Here, the extension direction of the connection pipe 3 (indicated by "X" in the drawing) is defined as the "cylinder axis direction", the side in the cylinder axis direction where the suction tool 2 is located is defined as the "one end side", and the side where the vacuum cleaner body 4 is located is defined as the "other end side". The extension direction of the head 21 of the suction tool 2 (indicated by "Y" in the drawing) is defined as the "left-right direction", which is perpendicular to the cylinder axis direction. Moreover, the direction perpendicular to the left-right direction and perpendicular to the cylinder axis direction in an imaginary plane including the cylinder axis direction (indicated by "Z" in the drawing) is defined as the "front-rear direction".
Usually, when cleaning a floor surface, the head portion 21 of the suction tool 2 is moved in the front-rear direction, and the side where the head portion 21 is located is the front side or front side, and the side where the operator is located is the rear side or back side. Also, when the cylinder axis direction coincides with the up-down direction, the front-back direction coincides with the front-back direction, so the front-back direction may be referred to as the "front-rear direction" even when the cylinder axis direction does not coincide with the up-down direction.
The vacuum cleaner support device 6 detachably supports the vacuum cleaner 1 with the connection pipe 3 parallel to the vertical direction or nearly so. The vacuum cleaner support device 6 includes a base 7 for placing the suction tool 2 of the vacuum cleaner 1, and a support pole 8 for supporting the back side of the vacuum cleaner 1 placed on the base 7. Here, an auxiliary dust collector 9 is provided on the support pole 8 so as to be retractable therefrom.
The electric vacuum cleaner 1 and the vacuum cleaner support device 6 will now be described.

操作ボタンは、例えば、電気掃除機のＯＮ・ＯＦＦスイッチ、吸込具２の回転ブラシのＯＮ・ＯＦＦスイッチ等である。これらのスイッチは回路モジュールに接続されている。 (1-5) Hand-operated operation unit The hand-operated operation unit 43 includes a handle unit 431 for operating (holding) the vacuum cleaner 1 when cleaning, an operation button (not shown) provided near the handle unit 431, and a release operation unit 48 for operating the main body side lock/release mechanism 46 to release the fixed connection between the vacuum cleaner main body 4 and the connection pipe 3. The release operation unit 48 will be described later.
The handle portion 431 utilizes the space 401d between the L-shaped portion 401a and the inverted L-shaped portion 401e, and is constituted by a bent region of the L-shaped portion 401a and a bent region 403a of the front cover 406.
The operation buttons are, for example, an ON/OFF switch for the vacuum cleaner, an ON/OFF switch for the rotating brush of the suction tool 2, etc. These switches are connected to the circuit module.

（１－６）配線部
配線部４５は、吸込具２の回転ブラシを回転駆動するモータに電力を供給するための配線（図示省略）を筐体本体４０１のＬ字状部分４０１ａの表面に沿って備え、表カバー４０３により覆われている。 (1-6) Wiring section The wiring section 45 has wiring (not shown) for supplying power to the motor that rotates the rotating brush of the suction tool 2, which is provided along the surface of the L-shaped portion 401a of the housing main body 401 and is covered by the front cover 403.

（２）接続パイプ
図１を用いて説明する。
接続パイプ３は、筒状をし、一端側が吸込具２に着脱可能に接続され、他端側が掃除機本体４に着脱可能に接続されている。接続パイプ３は、筒状部３１と、筒状部３１の表側を覆う表カバー３３とを備える。
図５に示すように、接続パイプ３の他端部３ａには、本体側ロック・解除機構４６がロックする本体側被ロック部３５が設けられている。ここでは、ロック機構に係合構造が利用され、本体側被ロック部３５は、解除機構４６が係合する係合孔（貫通孔）３５ａにより構成されている。 (2) Connecting Pipes This will be explained with reference to FIG.
The connection pipe 3 is cylindrical, with one end detachably connected to the suction tool 2 and the other end detachably connected to the vacuum cleaner body 4. The connection pipe 3 includes a cylindrical portion 31 and an outer cover 33 that covers the outer side of the cylindrical portion 31.
5, the other end 3a of the connection pipe 3 is provided with a main body side locked portion 35 that is locked by a main body side lock/unlock mechanism 46. Here, an engagement structure is used for the lock mechanism, and the main body side locked portion 35 is configured with an engagement hole (through hole) 35a with which the unlock mechanism 46 engages.

接続パイプ３の一端部には、吸込具２との接続状態をロックする吸込具側ロック機構が設けられている。ここでの吸込具側ロック機構は、係合構造が利用され、回転可能に支持された係合体３７により構成されている。係合体３７は、その回転支持位置よりも他端側に位置し且つ表カバー３３から露出する吸込具側操作部と、回転支持位置よりも一端側に位置し且つ裏側に突出する凸部を有する係合部とを有し、係合部が吸込具２の係合孔（図示省略、吸込具側被ロック部である）に係合する。なお、吸込具側操作部を押圧することで、係合体３７が回転して係合部の係合孔への係合が解除される。 A suction tool side locking mechanism that locks the connection with the suction tool 2 is provided at one end of the connection pipe 3. The suction tool side locking mechanism here utilizes an engagement structure and is composed of an engagement body 37 that is rotatably supported. The engagement body 37 has a suction tool side operating part that is located on the other end side of the rotation support position and is exposed from the front cover 33, and an engagement part that is located on the one end side of the rotation support position and has a convex part that protrudes to the back side, and the engagement part engages with an engagement hole (not shown, suction tool side locked part) of the suction tool 2. Note that by pressing the suction tool side operating part, the engagement body 37 rotates and the engagement part is released from the engagement hole.

（３）吸込具
図１を用いて説明する。
吸込具２は、左右方向に延伸するヘッド部２１の底部に吸込口を有し、その内部に回転ブラシ（図示省略）を収容する。
吸込具２は、ヘッド部２１の左右方向の中央から接続パイプ３側に筒状に延伸する延伸筒部２３を有している。延伸筒部２３の内部とヘッド部２１の底部の吸込口とは連通している。
吸込具２の延伸筒部２３は、接続パイプ３の一端部に挿入されることで、接続パイプ３と接続される。延伸筒部２３の他端には、接続パイプ３との接続を固定する吸込具側ロック機構の係合部が係合するための係合孔（吸込具側被ロック部）が設けられている。
吸込具２は、立設状態にある電気掃除機１を前側から支持する支持部２５を有している。ここでの支持部２５は、拡大図に示すように、欠け部分により構成され、この欠け部分に延伸筒部２３が嵌合することで、延伸筒部２３を前側から支持すると共に左右方向にも位置決めされる。 (3) Suction Tool This will be explained with reference to FIG.
The suction tool 2 has a suction port at the bottom of a head portion 21 that extends in the left-right direction, and houses a rotating brush (not shown) inside.
The suction tool 2 has an extended tube portion 23 that extends in a cylindrical shape from the center in the left-right direction of the head portion 21 toward the connection pipe 3. The inside of the extended tube portion 23 and the suction port at the bottom of the head portion 21 are in communication with each other.
The extension tube portion 23 of the suction tool 2 is inserted into one end of the connection pipe 3, thereby being connected to the connection pipe 3. The other end of the extension tube portion 23 is provided with an engagement hole (suction tool side locked portion) for engaging with an engagement portion of the suction tool side locking mechanism that fixes the connection to the connection pipe 3.
The suction tool 2 has a support part 25 that supports the vacuum cleaner 1 in an upright position from the front side. As shown in the enlarged view, the support part 25 here is configured with a cutout part, and the extension tube part 23 fits into this cutout part, thereby supporting the extension tube part 23 from the front side and positioning it in the left-right direction.

（４）本体側ロック・解除機構
図３及び図４を用いて説明する。
本体側ロック・解除機構４６は本体側ロック機構４６０と本体側解除機構４６５との両機能を有する。
（４－１）本体側ロック機構
本体側ロック機構４６０は係合構造を利用している。本体側ロック機構４６０は、接続パイプ３の他端に設けられている本体側被ロック部３５の係合孔３５ａ（図５参照）に係合する係合部４６１を有する。係合部４６１は左右方向を回転軸として回転可能に支持されている。具体的には、係合部４６１は軸部４６２から裏側に延伸し、図４に示すように、パイプ接続部４４の周壁の貫通孔４４ａを貫通して内部へ張り出している。なお、この張出部分４６１ａが接続パイプ３の他端部の係合孔３５ａ（図５参照）に係合する。
なお、係合部４６１の張出部分４６１ａがパイプ接続部４４の内側に入るように回転する方向（向き）を係合方向とし、係合部４６１の張出部分４６１ａがパイプ接続部４４の内側から外側に回転する方向（向き）を解除方向とする。 (4) Main Unit Lock/Unlock Mechanism This will be explained with reference to Figs.
The main body side lock/release mechanism 46 has the functions of both a main body side lock mechanism 460 and a main body side release mechanism 465 .
(4-1) Main Body Locking Mechanism The main body locking mechanism 460 utilizes an engagement structure. The main body locking mechanism 460 has an engagement portion 461 that engages with the engagement hole 35a (see FIG. 5) of the main body locked portion 35 provided at the other end of the connection pipe 3. The engagement portion 461 is supported so as to be rotatable about the left-right direction as a rotation axis. Specifically, the engagement portion 461 extends from the shaft portion 462 to the rear side, and as shown in FIG. 4, penetrates the through hole 44a in the peripheral wall of the pipe connection portion 44 and protrudes inward. The protruding portion 461a engages with the engagement hole 35a (see FIG. 5) at the other end of the connection pipe 3.
The direction (orientation) in which the protruding portion 461a of the engaging portion 461 rotates to enter the inside of the pipe connection portion 44 is defined as the engagement direction, and the direction (orientation) in which the protruding portion 461a of the engaging portion 461 rotates from the inside to the outside of the pipe connection portion 44 is defined as the release direction.

（４－２）本体側解除機構
本体側解除機構４６５は、本体側ロック機構４６０の係合部４６１を本体側被ロック部３５の係合孔３５ａから抜ける方向（解除方向）に移動させて、接続状態の固定（係合）を解除する。
ここでの本体側解除機構４６５は、手元操作部４３の解除操作部４８（図２参照）の操作により係合部４６１を解除方向に回転させるための可動部４６６を備える。可動部４６６は軸部４６２から径方向に突出する。ここでは、可動部４６６は軸部４６２に一体に設けられている。可動部４６６における係合部４６１側の面は、筒軸方向と交差し、軸体４８５の筒軸方向の一端部と当接又は近接する。これにより、軸体４８５が筒軸方向を一端側に移動することで、可動部４６６が軸部４６２の回りを解除方向へと移動する。これにより、可動部４６６と一体化されている係合部４６１が解除方向に回転移動する。 (4-2) Body-side Release Mechanism The body-side release mechanism 465 moves the engaging portion 461 of the body-side locking mechanism 460 in a direction (releasing direction) in which it comes out of the engaging hole 35a of the body-side locked portion 35, thereby releasing the fixed (engaged) connected state.
The main body side release mechanism 465 here includes a movable part 466 for rotating the engagement part 461 in the release direction by operating the release operation part 48 (see FIG. 2) of the hand operation part 43. The movable part 466 protrudes in the radial direction from the shaft part 462. Here, the movable part 466 is provided integrally with the shaft part 462. The surface of the movable part 466 on the engagement part 461 side intersects with the cylindrical axis direction and abuts or comes close to one end of the shaft body 485 in the cylindrical axis direction. As a result, the shaft body 485 moves in the cylindrical axis direction toward the one end side, and the movable part 466 moves around the shaft part 462 in the release direction. As a result, the engagement part 461 integrated with the movable part 466 rotates and moves in the release direction.

本体側解除機構４６５は、上記の解除操作部４８の解除操作以外の操作により、係合部４６１を解除方向に回転させるための操作部４６７を備えてもよい。操作部４６７は、図４に示すように、掃除機本体４のパイプ接続部４４の表カバー４０３の開口４０３ｂを利用して操作可能に構成されている。
操作部４６７は、開口４０３ｂ内に配され且つ裏側が開口する箱状をする箱状部分４６７ａと、箱状部分４６７ａと軸部４６２とを連結する連結部分４６７ｂとを有する。なお、箱状部分４６７ａが開口４０３ｂに対して押し込まれる（退避する）と、軸部４６２が回転し、結果的に係合部４６１が解除方向に移動（回転）する。
なお、図示しないが、操作部４６７（箱状部分４６７ａ）とパイプ接続部４４の周壁との間には、押し込まれた操作部４６７を元の位置に戻すように付勢する付勢機構（例えばバネ体）が設けられている。付勢機構の図示は省略している。 The main body side release mechanism 465 may include an operation unit 467 for rotating the engagement unit 461 in the release direction by an operation other than the release operation of the release operation unit 48. The operation unit 467 is configured to be operable by utilizing the opening 403b of the front cover 403 of the pipe connection unit 44 of the vacuum cleaner main body 4, as shown in FIG.
The operating portion 467 has a box-shaped portion 467a that is disposed in the opening 403b and has a box shape with an open back side, and a connecting portion 467b that connects the box-shaped portion 467a to the shaft portion 462. When the box-shaped portion 467a is pushed (retracted) into the opening 403b, the shaft portion 462 rotates, and as a result, the engaging portion 461 moves (rotates) in the release direction.
Although not shown, a biasing mechanism (e.g., a spring body) that biases the pushed-in operating part 467 so as to return it to its original position is provided between the operating part 467 (box-shaped part 467a) and the peripheral wall of the pipe connection part 44. The biasing mechanism is not shown.

上述のように、ここでの本体側ロック・解除機構４６は、係合部４６１と軸部４６２と可動部４６６と操作部４６７とを一体に備える回転移動体４６８により構成されている。回転移動体４６８は、図３の（ａ）に示すように、配線部４５の表壁に形成された軸支持部４５ａに軸部４６２が回転可能に支持され、操作部４６７の箱状部分４６７ａが表カバー４０３の開口４０３ｂ内に位置する状態で、表カバー４０３により覆われている。
なお、本実施形態の第３方向は、軸部４６２の軸心を回転中心とする回転移動体４６８の回転方向であり、回転移動体４６８の係合方向の回転の向きが本実施形態の一方側であり、回転移動体４６８の解除方向の回転の向きが本実施形態の他方側である。 As described above, the main body side lock/unlock mechanism 46 here is composed of a rotational moving body 468 integrally including an engagement portion 461, a shaft portion 462, a movable portion 466, and an operation portion 467. As shown in Fig. 3A, the rotational moving body 468 is covered by the front cover 403 with the shaft portion 462 rotatably supported by a shaft support portion 45a formed on the front wall of the wiring portion 45, and the box-shaped portion 467a of the operation portion 467 positioned within the opening 403b of the front cover 403.
In addition, the third direction in this embodiment is the rotational direction of the rotational moving body 468 with the axis of the shaft portion 462 as the rotation center, and the rotational direction of the rotational moving body 468 in the engagement direction is one side in this embodiment, and the rotational direction of the rotational moving body 468 in the release direction is the other side in this embodiment.

（５）解除操作部
主に図６及び図７を用いて説明する。
解除操作部４８は、掃除機本体４における接続パイプ３との接続位置よりも手元操作部４３側に設けられている。解除操作部４８は、使用者から解除操作を受け付ける操作受付部材４８１と、操作受付部材４８１の受付動作により本体側解除機構４６５（図４参照）を動作させる動作部材４８３とを備える。 (5) Release Operation Portion This will be explained mainly with reference to FIGS. 6 and 7. FIG.
The release operation unit 48 is provided on the hand operation unit 43 side of the connection position between the vacuum cleaner body 4 and the connection pipe 3. The release operation unit 48 includes an operation acceptance member 481 that accepts a release operation from the user, and an operation member 483 that operates the main body side release mechanism 465 (see FIG. 4 ) in response to the acceptance operation of the operation acceptance member 481.

（５－１）操作受付部材
操作受付部材４８１は、筒軸方向と交差する第２方向に移動可能に支持されている。ここでは、第２方向は表裏方向である。操作受付部材４８１は、裏側が開放する箱状部４８１ａと、箱状部４８１ａの開口縁から外方へ張り出す鍔部４８１ｂとを有する。
操作受付部材４８１は、筐体本体４０１のＬ字状部分４０１ａと表カバー４０３との間に配され、箱状部４８１ａが表カバー４０３の開口４０３ｃに嵌合する。
なお、鍔部４８１ｂは開口４０３ｃよりも大きい。これにより、操作受付部材４８１の箱状部４８１ａが開口４０３ｃに対して出退可能に支持される。使用者による操作受付部材４８１の受付動作は、使用者の箱状部４８１ａの押込みによる裏側への移動である。 (5-1) Operation Receiving Member The operation receiving member 481 is supported so as to be movable in a second direction intersecting with the axial direction. Here, the second direction is the front-to-back direction. The operation receiving member 481 has a box-shaped portion 481a that is open on the back side, and a flange portion 481b that protrudes outward from the opening edge of the box-shaped portion 481a.
The operation receiving member 481 is disposed between the L-shaped portion 401 a of the housing main body 401 and the front cover 403 , and the box-shaped portion 481 a fits into an opening 403 c of the front cover 403 .
The flange 481b is larger than the opening 403c. This allows the box-shaped portion 481a of the operation receiving member 481 to be supported so as to be able to move in and out of the opening 403c. The receiving operation of the operation receiving member 481 by the user is performed by the user pushing the box-shaped portion 481a to move it to the back side.

操作受付部材４８１は、箱状部４１８ａの底面（裏面）から裏側に突出する突出部４８１ｃを備える。突出部４８１ｃにおける筒軸方向の一端側が傾斜面４８１ｄとなっている。
傾斜面４８１ｄは、当該傾斜面上を突出部４８１ｃの基部側から突出側に向かう（図６においてＺ方向の裏側に進む）にしたがって、箱状部４１８ａの底面から離れるように傾斜している。具体的に、突出部４８１ｃの筒軸方向の他端側の端面は筒軸方向と直交し、突出部４８１ｃの筒軸方向の寸法に着目して換言すると、左右方向に直交する断面（図６である）において、裏側に近づくにしたがって突出部４８１ｃの筒軸方向の寸法が小さくなるように傾斜している。
突出部４８１ｃの傾斜面４８１ｄは、動作部材４８３の他端部と当接し、使用者からの操作受付部材４８１の押込みによる移動力を動作部材４８３に伝達する力伝達部を構成する。なお、傾斜面４８１ｄは、後述の力変換体４８７の傾斜面４８７ｄと当接する。 The operation receiving member 481 includes a protruding portion 481c protruding from the bottom surface (rear surface) of the box-shaped portion 418a toward the rear side. One end side of the protruding portion 481c in the cylinder axis direction is an inclined surface 481d.
The inclined surface 481d is inclined so as to move away from the bottom surface of the box-shaped portion 418a as it moves from the base side of the protruding portion 481c toward the protruding side (progressing toward the back side in the Z direction in FIG. 6) on the inclined surface. Specifically, the end face on the other end side of the cylindrical axis direction of the protruding portion 481c is perpendicular to the cylindrical axis direction, and in other words, focusing on the dimension of the protruding portion 481c in the cylindrical axis direction, in a cross section (FIG. 6) perpendicular to the left-right direction, the dimension of the protruding portion 481c in the cylindrical axis direction is inclined so as to become smaller as it approaches the back side.
The inclined surface 481d of the protruding portion 481c abuts against the other end of the operating member 483 and constitutes a force transmitting portion that transmits the moving force caused by the user pressing the operation accepting member 481 to the operating member 483. The inclined surface 481d abuts against an inclined surface 487d of a force converter 487 described later.

（５－２）動作部材
動作部材４８３は、筒軸方向に移動可能に支持され、操作受付部材４８１の受付動作により筒軸方向を一端側（接続位置側）に移動する。
動作部材４８３は、筒軸方向に延伸する軸体４８５と、操作受付部材４８１の裏側への移動力を軸体４８５の一端側への移動力に変換する力変換体４８７とを備える。なお、ここでは、軸体４８５と力変換体４８７は他部材で構成されているが、例えば、一部材で構成してもよい。なお、軸体４８５は本実施形態の軸部の一例に相当し、力変換体４８７は本実施形態の力変換部の一例に相当する。 (5-2) Movement Member The movement member 483 is supported so as to be movable in the axial direction, and moves in the axial direction toward one end (the connection position) in response to a reception operation of the operation reception member 481 .
The operating member 483 includes a shaft body 485 extending in the axial direction of the cylinder, and a force converter 487 that converts a moving force of the operation receiving member 481 toward the back side into a moving force toward one end side of the shaft body 485. Note that, although the shaft body 485 and the force converter 487 are made of different members here, they may be made of a single member, for example. Note that the shaft body 485 corresponds to an example of a shaft portion in this embodiment, and the force converter 487 corresponds to an example of a force converter in this embodiment.

（５－２－１）軸体
軸体４８５は、横断面形状が円形状の棒状をし、図７の（ａ）に示すように、Ｌ字状部分４０１ａの表面に形成されたリブ４０１ｇの凹み４０１ｈに嵌るようにして支持されている。なお、リブ４０１ｇは左右方向に延伸し、筒軸方向に間隔をおいて複数個設けられている。各リブ４０１ｇの左右方向の端部は、筒軸方向に延伸するリブ４０１ｉにより補強（連結）されている。軸体４８５の他端側は後述の力変換体４８７に固定されている。 (5-2-1) Shaft The shaft 485 is rod-shaped with a circular cross section, and is supported by fitting into a recess 401h of a rib 401g formed on the surface of the L-shaped portion 401a, as shown in Fig. 7(a). The ribs 401g extend in the left-right direction, and a plurality of ribs 401g are provided at intervals in the axial direction. The left-right ends of each rib 401g are reinforced (connected) by a rib 401i extending in the axial direction. The other end of the shaft 485 is fixed to a force converter 487, which will be described later.

（５－２－２）力変換体
力変換体４８７は筒軸方向の移動可能に支持されている。ここでは、図７の（ａ）に示すように、力変換体４８７の裏面が筐体本体４０１の表面に当接し、力変換体４８７の左右端面が筐体本体４０１から筒軸方向に沿って表側に延伸するリブ４０１ｊと当接する。
力変換体４８７は全体として筒軸方向に長い直方体状に似た形状をしている。力変換体４８７は、筒軸方向に延伸する縦溝部４８７ａと、左右方向に延伸する横溝部４８７ｂとを有し、他端部４８７ｃの端面が傾斜面４８７ｄとなっている。 (5-2-2) Force conversion body The force conversion body 487 is supported so as to be movable in the axial direction. Here, as shown in Fig. 7A, the back surface of the force conversion body 487 abuts against the surface of the housing body 401, and the left and right end surfaces of the force conversion body 487 abut against ribs 401j extending from the housing body 401 to the front side along the axial direction.
The force converter 487 has a shape resembling a rectangular parallelepiped that is long in the axial direction as a whole. The force converter 487 has a vertical groove 487a extending in the axial direction and a horizontal groove 487b extending in the left-right direction. The end surface of the other end 487c forms an inclined surface 487d.

縦溝部４８７ａは軸体４８５を固定するためのものである。縦溝部４８７ａは、筒軸方向の一端側に形成され、当該縦溝部４８７ａに軸体４８５の他端部が嵌合する。なお、縦溝部４８７ａと軸体４８５の他端部とは固定されている。固定として、縦溝部４７８ａによって軸体４８５を挟む力によって固定が実現されてもよいし、例えば接着剤や係合構造を使用して固定してもよい。これにより、軸体４８５と力変換体４８７とが筒軸方向に一体で移動可能となる。 The vertical groove 487a is for fixing the shaft body 485. The vertical groove 487a is formed on one end side in the axial direction of the cylinder, and the other end of the shaft body 485 fits into the vertical groove 487a. The vertical groove 487a and the other end of the shaft body 485 are fixed to each other. Fixation may be achieved by the force of the vertical groove 478a clamping the shaft body 485, or it may be fixed using, for example, an adhesive or an engagement structure. This allows the shaft body 485 and the force conversion body 487 to move together in the axial direction of the cylinder.

横溝部４８７ｂは筒軸方向の略中央に形成されている。横溝部４８７ｂは、図６に示すように、表裏方向に出退する操作受付部材４８１の鍔部４８１ｂ用のスペースである。操作受付部材４８１が使用者の押し込みにより動作部材４８３が筒軸方向の一端側に移動した際に、箱状部４８１ａにおける筒軸方向の一端側に位置する側壁の内面と、横溝部４８７ｂを構成している他端側の側面とが当接する。これにより、動作部材４８３が筒軸方向の一端側に抜けるのを防止できる。
なお、横溝部４８７ｂの筒軸方向の一端側と縦溝部４８７ａとは操作受付部材４８１の外側に位置し、横溝部４８７ｂの筒軸方向の他端側と他端部４８７ｃとは操作受付部材４８１の箱状部４８１ａ内に位置する。 The lateral groove 487b is formed in the approximate center in the axial direction. As shown in Fig. 6, the lateral groove 487b is a space for the flange 481b of the operation receiving member 481, which moves in and out in the front-to-back direction. When the user presses the operation receiving member 481 and the operating member 483 moves to one end in the axial direction, the inner surface of the side wall located at one end in the axial direction of the box-shaped portion 481a comes into contact with the side surface of the other end that constitutes the lateral groove 487b. This makes it possible to prevent the operating member 483 from slipping out to one end in the axial direction.
In addition, one end side of the horizontal groove portion 487b in the axial direction and the vertical groove portion 487a are located outside the operation receiving member 481, and the other end side of the horizontal groove portion 487b in the axial direction and the other end portion 487c are located inside the box-shaped portion 481a of the operation receiving member 481.

他端部４８７ｃの傾斜面４８７ｄは、当該傾斜面上を筒軸方向の他端側（図６において右側）から筒軸方向の一端側（図６における左側）に向かうにしたがって操作受付部材４８１の箱状部４８１ａに近づくように傾斜する。
傾斜面４８７ｄは、操作受付部材４８１の突出部４８１ｃの傾斜面４８１ｄ（力伝達部）と当接する。これにより、操作受付部材４８１が裏側に移動すると、力変換体４８７の傾斜面４８７ｄが操作受付部材４８１側の傾斜面４８１ｄに沿ってズレて（せり出して）、力変換体４８７が筒軸方向の一端側に押し出される。つまり、操作受付部材４８１の裏側への移動力を軸体４８５の一端側への移動力に変換することができる。
なお、図示していないが、軸体４８５を支持し且つ筒軸方向の最も他端側に位置するリブ４０１ｇと力変換体４８７の一端部との間には、軸体４８５に嵌められたバネ体が設けられていてもよい。これにより、使用者により一旦押し込まれた操作受付部材４８１を開口４０３ｂから出方向に戻すように構成されている。つまり、使用者による解除操作を元に戻すように付勢する付勢機構を備えている。 The inclined surface 487d of the other end 487c inclines so as to approach the box-shaped portion 481a of the operation receiving member 481 as it moves from the other end side in the axial direction (the right side in Figure 6) to one end side in the axial direction (the left side in Figure 6).
The inclined surface 487d comes into contact with the inclined surface 481d (force transmission portion) of the protruding portion 481c of the operation receiving member 481. As a result, when the operation receiving member 481 moves to the rear side, the inclined surface 487d of the force conversion body 487 shifts (protrudes) along the inclined surface 481d on the operation receiving member 481 side, and the force conversion body 487 is pushed out to one end side in the tubular axis direction. In other words, the moving force of the operation receiving member 481 toward the rear side can be converted into a moving force toward one end side of the shaft body 485.
Although not shown, a spring body fitted to the shaft body 485 may be provided between the rib 401g that supports the shaft body 485 and is located at the other end side in the axial direction of the cylinder and one end of the force converter 487. This is configured to return the operation receiving member 481 once pushed in by the user in the direction of exit from the opening 403b. In other words, a biasing mechanism is provided that biases the release operation by the user to return to the original state.

（６）離間機構
（６－１）の構造
図３及び図４を用いて説明する。
離間機構４９は、解除操作部４８の操作により接続パイプ３側に突出する突出部材４９１を備える。突出部材４９１は、ベース部４９１ａと、ベース部４９１ａから筒軸方向の一端側に延伸する延伸部４９１ｂとを備える。ここでの延伸部４９１ｂは例えば円柱状をしている。
ここでは、延伸部４９１ｂが筐体本体４０１のリブ４０１ｋの貫通孔４０１ｍを挿通し、ベース部４９１ａの裏面が筐体本体４０１に当接し、ベース部４９１ａの表面が表カバー４０３に当接することで、ガタツキなく筒軸方向に移動可能に支持される。ここで、貫通孔４０１ｍは、リブ４０１ｋに設けられた２つの貫通孔４０１ｎの間に設けられる。この２つの貫通孔４０１ｎは、筐体本体４０１側の配線と接続パイプ３側の配線とを電気的に接続するための一対の電極ピン３６が挿入される孔である。 (6) Structure of the Separation Mechanism (6-1) This will be explained with reference to Figs. 3 and 4.
The separation mechanism 49 includes a protruding member 491 that protrudes toward the connection pipe 3 by operating the release operating part 48. The protruding member 491 includes a base part 491a and an extension part 491b that extends from the base part 491a toward one end side in the cylindrical axis direction. The extension part 491b here has, for example, a cylindrical shape.
Here, the extension portion 491b is inserted through a through hole 401m of a rib 401k of the housing body 401, the back surface of the base portion 491a abuts against the housing body 401, and the front surface of the base portion 491a abuts against the front cover 403, so that the extension portion 491b is supported so as to be movable in the axial direction without rattling. Here, the through hole 401m is provided between two through holes 401n provided in the rib 401k. These two through holes 401n are holes into which a pair of electrode pins 36 for electrically connecting the wiring on the housing body 401 side and the wiring on the connection pipe 3 side are inserted.

突出部材４９１は、ベース部４９１ａの筒軸方向の他端側に傾斜面４９１ｃを有している。傾斜面４９１ｃは、当該傾斜面上を筒軸方向の一端側から他端側に向かうにしたがって表カバー４０３の裏面から離れるように傾斜している。傾斜面４９１ｃは本体側解除機構の操作部４６７の裏面と当接している。これにより、操作部４６７が軸部４６２の回りを解除方向に回転するにしたがって、傾斜面４９１ｃが筒軸方向の他端側から一端側にせり出すことで、突出部材４９１が筒軸方向の一端側に押し出される。このように、操作部４６７の解除方向の移動力を突出部材４９１の一端側への移動力に変換できる。
また、ここでは、解除操作部４８が使用者により解除操作されて軸体４８５が移動し、軸体４８５に当接する可動部４６６が軸部４６２の回りを解除方向に回転することで、突出部材４９１が筒軸方向の一端に向かって移動する。したがって、この突出部材４９１の押し出しの動きによって、接続パイプ３をパイプ接続部４４から離脱させる方向に押し出すことができる。 The protruding member 491 has an inclined surface 491c on the other end side of the base portion 491a in the axial direction. The inclined surface 491c is inclined so as to move away from the rear surface of the front cover 403 as it moves from one end side to the other end side in the axial direction on the inclined surface. The inclined surface 491c abuts against the rear surface of the operating portion 467 of the main body side release mechanism. As a result, as the operating portion 467 rotates around the shaft portion 462 in the release direction, the inclined surface 491c protrudes from the other end side in the axial direction to one end side, and the protruding member 491 is pushed out to one end side in the axial direction. In this way, the moving force of the operating portion 467 in the release direction can be converted into a moving force toward one end side of the protruding member 491 in the axial direction.
In addition, here, when the release operation portion 48 is released by the user, the shaft body 485 moves, and the movable portion 466 in contact with the shaft body 485 rotates around the shaft portion 462 in the release direction, so that the protruding member 491 moves toward one end in the axial direction of the cylinder. Therefore, the pushing movement of the protruding member 491 can push the connection pipe 3 in a direction to separate it from the pipe connection portion 44.

解除操作部４８を操作する際、例えば、使用者は、接続パイプ３を把持して接続パイプ３を支持した状態で行ってもよいし、電気掃除機１を自立させた状態で行ってもよい。特に、自立状態で行う場合、離間機構４９により接続パイプ３と掃除機本体４とを離間させるため、使用者が接続パイプ３に触れることなく、接続パイプ３と掃除機本体４とを分離することができる。また、自立状態では、接続パイプ３及び吸込具２の重力が作用する方向と突出部材４９１が突出する方向とが略一致するため、接続パイプ３が掃除機本体４から外れやすくできる。なお、自立状態で掃除機本体４と分離した接続パイプ３はそのまま転倒することなく、自立状態を維持できるため、使用者にとって非常に使い勝手の良いものとなる。 When operating the release operation unit 48, for example, the user may hold the connection pipe 3 to support the connection pipe 3, or may operate the vacuum cleaner 1 in a self-supporting state. In particular, when operating the vacuum cleaner 1 in a self-supporting state, the separation mechanism 49 separates the connection pipe 3 from the vacuum cleaner body 4, so the user can separate the connection pipe 3 from the vacuum cleaner body 4 without touching the connection pipe 3. In addition, in a self-supporting state, the direction in which gravity acts on the connection pipe 3 and the suction tool 2 and the direction in which the protruding member 491 protrudes are approximately the same, so that the connection pipe 3 can be easily removed from the vacuum cleaner body 4. In addition, the connection pipe 3 separated from the vacuum cleaner body 4 in a self-supporting state can maintain its self-supporting state without falling over, making it very easy for the user to use.

３．掃除機支持装置
主に図１を用いて説明する。
（１）掃除機支持装置
掃除機支持装置６は、上述のように載置台７と支柱８とを備える。
載置台７は、偏平な箱状をし、前面の開口（上面の開口の図示は省略）から後方へと延び且つ補助集塵具９のヘッド部を挿入できる挿入空間７１を有する。
載置台７の上面には挿入空間７１に連通する貫通孔を左右方向に複数個有している。上面の貫通孔は、載置台７に載置された電気掃除機１の吸込具２の吸込口と対向するように設けられている。
支柱８は、下支柱部８１と上支柱部８３とを備え、上支柱部８３が電気掃除機１の接続パイプ３を後方から支持する。支柱８は、上支柱部８３に補助集塵具９を収容するボックス８５を着脱可能に備える。
支柱８（上支柱部８３）は、ボックス８５を装着するための装着部を有する。ここでのボックス９５は、上下方向に長く且つ少なくとも上面が開放する箱状をしている。ボックス９５における支柱８と対向する対向壁には上支柱部８３に上下に間隔をおいて設けられた２個の係合片があり、当該係合片が係合する係合溝が装着部として形成されている。なお、装着部（係合溝）は、上支柱部８３の左右方向の左右壁と、左右方向と直交する方向の後側の後壁とに設けられ、ボックス８５の取り付け位置を選択できる。 3. Vacuum Cleaner Support Device The following will be explained mainly with reference to FIG.
(1) Vacuum Cleaner Support Device The vacuum cleaner support device 6 includes the mounting base 7 and the support pole 8 as described above.
The mounting table 7 has a flat box shape, extends rearward from an opening on the front surface (the opening on the top surface is not shown), and has an insertion space 71 into which the head portion of the auxiliary dust collector 9 can be inserted.
The upper surface of the mounting base 7 has a plurality of through holes in the left-right direction that communicate with the insertion space 71. The through holes in the upper surface are provided so as to face the suction port of the suction tool 2 of the electric vacuum cleaner 1 placed on the mounting base 7.
The support 8 includes a lower support portion 81 and an upper support portion 83, and the upper support portion 83 supports the connection pipe 3 of the vacuum cleaner 1 from behind. The support 8 includes a box 85 that houses the auxiliary dust collector 9 and is detachably attached to the upper support portion 83.
The support 8 (upper support portion 83) has an attachment portion for attaching the box 85. The box 95 here is a box-shaped portion that is long in the vertical direction and at least the top is open. On the opposing wall of the box 95 that faces the support 8, there are two engagement pieces that are provided at an interval above and below on the upper support portion 83, and engagement grooves with which the engagement pieces engage are formed as attachment portions. The attachment portions (engagement grooves) are provided on the left and right walls of the upper support portion 83 in the horizontal direction and on the rear wall on the rear side in the direction perpendicular to the horizontal direction, so that the attachment position of the box 85 can be selected.

（２）補助集塵具
補助集塵具９は、モップ、埃取り、ブラシ、ほうき、たわし、などの清掃用具である。補助集塵具９は図外のヘッド部と柄部９１を備える。
ヘッド部は、柄部９１に着脱可能に装着され、交換可能に構成されている。
柄部９１は、図９に示すように、ヘッド部が一端に装着される内パイプ９１１と、内パイプ９１１を伸縮可能に収容する外パイプ９１３と、内パイプ９１１を外パイプ９１３に対して位置決めする位置決め機構９１５と、外パイプ９１３の上端を覆うキャップ９１７とを少なくとも有する。 (2) Auxiliary Dust Collector The auxiliary dust collector 9 is a cleaning tool such as a mop, duster, brush, broom, scrubbing brush, etc. The auxiliary dust collector 9 includes a head portion and a handle portion 91, not shown.
The head portion is removably attached to the handle portion 91 and configured to be replaceable.
As shown in Figure 9, the handle portion 91 has at least an inner pipe 911 to one end of which the head portion is attached, an outer pipe 913 that houses the inner pipe 911 in an expandable and contractible manner, a positioning mechanism 915 that positions the inner pipe 911 relative to the outer pipe 913, and a cap 917 that covers the upper end of the outer pipe 913.

位置決め機構９１５は、内パイプ９１１に共回り状態で取り付けられるアダプター９１８と、アダプター９１８と外パイプ９１３との間に配されるストッパー９１９とを有する。
アダプター９１８は、内パイプ９１１の欠け部９１１ａに嵌合する凸部９１８ａと、ストッパー９１９が嵌合する嵌合部９１８ｂと、嵌合部９１８ｂの上下両端から外方へ張り出す下鍔部９１８ｃ、上鍔部９１８ｄとを備える。嵌合部９１８ｂの外周面は、同図の（ｃ）に示すように、外周面の半径が等しい円周面９１８ｅと、外周面を周方向に旋回するにしたがって中心から遠くなる拡径面９１８ｆとからなる。 The positioning mechanism 915 has an adapter 918 that is attached to the inner pipe 911 in a corotating state, and a stopper 919 that is disposed between the adapter 918 and the outer pipe 913 .
The adapter 918 includes a protrusion 918a that fits into the notch 911a of the inner pipe 911, a fitting portion 918b into which the stopper 919 fits, and a lower flange 918c and an upper flange 918d that protrude outward from both the upper and lower ends of the fitting portion 918b. As shown in (c) of the same figure, the outer peripheral surface of the fitting portion 918b is made up of a circumferential surface 918e having the same radius, and an expanding surface 918f that becomes farther from the center as it goes around the outer peripheral surface in the circumferential direction.

ストッパー９１９は、弾性変形可能なゴム材料により構成され、横断面形状が「Ｃ」字状をしている。「Ｃ」字の両端に位置する部位は厚肉部９１９ａとなっている。ストッパー９１９の外周面は外パイプ９１３の内周面に略当接し、外パイプ９１３が内パイプ９１１に対して回転すると、外パイプ９１３と共に回転する。
ストッパー９１９は、ストッパー９１９内であって一対の厚肉部９１９ａ間にアダプター９１８の嵌合部９１８ｂの拡径面９１８ｆが位置するように、アダプター９１８の嵌合部９１８ｂに嵌合する。これにより、外パイプ９１３が内パイプ９１１に対して回転すると、外パイプ９１３と共にストッパー９１９が回転し、やがてストッパー９１９の厚肉部９１９ａが拡径面９１８ｆに達すると、ストッパー９１９の厚肉部９１９ａが外パイプ９１３の内面を押圧し、外パイプ９１３が内パイプ９１１に固定される。 The stopper 919 is made of an elastically deformable rubber material and has a C-shaped cross section. The portions located at both ends of the C are thick-walled portions 919a. The outer peripheral surface of the stopper 919 is in approximate contact with the inner peripheral surface of the outer pipe 913, and when the outer pipe 913 rotates relative to the inner pipe 911, the stopper 919 rotates together with the outer pipe 913.
The stopper 919 fits into the fitting portion 918b of the adapter 918 so that the expanded diameter surface 918f of the fitting portion 918b of the adapter 918 is located between the pair of thick portions 919a inside the stopper 919. As a result, when the outer pipe 913 rotates relative to the inner pipe 911, the stopper 919 rotates together with the outer pipe 913, and when the thick portion 919a of the stopper 919 eventually reaches the expanded diameter surface 918f, the thick portion 919a of the stopper 919 presses the inner surface of the outer pipe 913, and the outer pipe 913 is fixed to the inner pipe 911.

以上、実施形態を説明したが、この実施形態に限られるものではなく、例えば、以下のような変形例であってもよい。また、実施形態と変形例、変形例同士を組み合わせたものであってもよい。
また、実施形態や変形例に記載していていない例や、要旨を逸脱しない範囲の設計変更があっても本発明に含まれる。 Although the embodiment has been described above, the present invention is not limited to this embodiment, and may be modified as follows, for example. In addition, the embodiment and the modified examples may be combined, or the modified examples may be combined.
Furthermore, examples not described in the embodiments and modifications, and design changes that do not depart from the gist of the present invention are also included in the present invention.

＜変形例＞ <Modification>

（１）電気掃除機１はスティック型の掃除機であったが、キャニスター型の掃除機であってもよい。この場合、掃除機本体に接続される可撓性のホース体の手元操作具と吸込体との接続部について適用できる。
（２）電気掃除機１は補助集塵具９を備えていないが、例えば、補助集塵具や補助集塵具の長手方向に間隔をおいて磁石を設け、補助集塵具を電気掃除機に着脱可能に装着するようにしてもよいし、補助集塵具を収納するためのボックス８５に磁石を設けて、電気掃除機に着脱可能に装着するようにしてもよい。
（３）電気掃除機１は集塵パックを収容するタイプの掃除機であったが、集塵パックの代わりに、集塵フィルタを電動送風機の上流側に設け、吸い込んだ塵埃を集塵ケース内に集塵するタイプ（いわゆるサイクロン式）であってもよい。
（４）実施形態では、吸込体が接続パイプ３と吸込具２とで構成され、掃除機本体４と吸込体との接続の一例として、掃除機本体４と接続パイプ３との接続について説明している。
しかしながら、本発明に係る接続は、例えば、吸込体を吸込具で構成し、接続パイプ付きの掃除機本体の接続パイプと吸込具との接続であってもよいし、吸込体を吸込具で構成し、接続パイプのない掃除機本体と吸込具との接続であってもよい。 (1) Although the electric vacuum cleaner 1 is a stick type vacuum cleaner, it may be a canister type vacuum cleaner. In this case, the present invention can be applied to a connection between a hand-operated tool of a flexible hose body connected to the vacuum cleaner body and a suction body.
(2) The electric vacuum cleaner 1 does not have an auxiliary dust collector 9. However, for example, magnets may be provided at intervals along the auxiliary dust collector or the longitudinal direction of the auxiliary dust collector so that the auxiliary dust collector can be removably attached to the electric vacuum cleaner, or a magnet may be provided in a box 85 for storing the auxiliary dust collector so that it can be removably attached to the vacuum cleaner.
(3) The electric vacuum cleaner 1 is a type that houses a dust collection bag, but instead of a dust collection bag, a dust collection filter may be provided upstream of the electric blower, and the sucked dust may be collected in a dust collection case (a so-called cyclone type).
(4) In the embodiment, the suction body is composed of the connection pipe 3 and the suction tool 2, and the connection between the vacuum cleaner body 4 and the connection pipe 3 is described as an example of the connection between the vacuum cleaner body 4 and the suction body.
However, the connection according to the present invention may be, for example, a connection between the suction tool and a connection pipe of a vacuum cleaner main body with a connecting pipe, or a connection between the suction tool and a vacuum cleaner main body without a connecting pipe, in which the suction body is formed of a suction tool.

（５）実施形態では、（本体側）ロック機構４６０と（本体側）解除機構４６５とが一体となった（本体側）ロック・解除機構４６について説明したが、ロック機構と解除機構とを別体で備えてもよい。なお、一体とした構造の方が簡易となる。
（６）実施形態の解除操作部４８は、筐体本体４０１のＬ字状部分４０１ａの直線領域に設けられているが、解除操作部をＬ字状部分４０１ａの屈曲領域に設けてもよい。なお、直線領域に解除操作部を設けると、直線状の軸体４８５を利用でき、その構造が簡易となる。
（７）実施形態の解除操作部４８は操作受付部材４８１と動作部材４８３とを別体で備えているが、例えば、操作受付部材と動作部材とを一体で備える構造にしてもよい。一例として、第１方向にスライド可能に設けられた動作部材の一部を使用者が直接スライドさせるような構造がある。 (5) In the embodiment, the (main body side) lock/release mechanism 46 is described as being integrated with the (main body side) lock mechanism 460 and the (main body side) release mechanism 465. However, the lock mechanism and the release mechanism may be provided separately. Note that an integrated structure is simpler.
(6) In the embodiment, the release operation unit 48 is provided in the straight region of the L-shaped portion 401a of the housing body 401. However, the release operation unit may be provided in the bent region of the L-shaped portion 401a. If the release operation unit is provided in the straight region, the straight shaft body 485 can be used, and the structure is simplified.
(7) Although the release operation unit 48 in the embodiment includes the operation acceptance member 481 and the operating member 483 as separate bodies, for example, the operation acceptance member and the operating member may be integrally provided. As an example, there is a structure in which the user directly slides a part of the operating member that is provided to be slidable in the first direction.

（８）実施形態の動作部材４８３は、解除操作があると第１方向を接続位置側に移動するが、例えば、ロック機構の係合方向と解除方向とを実施形態と逆になるように構成し、動作部材が第１方向を接続位置と反対側に移動するようにしてもよい。この場合、操作受付部材と動作部材との当接面を、第２方向を押込側に進むにしたがって第１方向を接続位置に近づくように傾斜させればよい。
（９）実施形態の動作部材の軸部は、棒状体により構成されているが、例えば、ワイヤー等の線条体を利用することもできる。この場合、操作受付部材の移動に合わせてワイヤーが接続位置と反対側に移動し、この移動によりロック機構の固定が解除するように構成すればよい。 (8) In the embodiment, the operating member 483 moves in the first direction toward the connected position when a release operation is performed, but for example, the engaging direction and releasing direction of the locking mechanism may be configured to be opposite to those in the embodiment, so that the operating member moves in the first direction toward the opposite side to the connected position. In this case, the contact surface between the operation receiving member and the operating member may be inclined so that the first direction approaches the connected position as the second direction proceeds toward the push-in side.
(9) Although the shaft of the operating member in the embodiment is configured with a rod-shaped body, for example, a filament such as a wire may be used. In this case, the wire may be configured to move in the opposite direction to the connection position in accordance with the movement of the operation receiving member, and this movement may be configured to release the fixation of the locking mechanism.

（１０）実施形態の離間機構４９は、（本体側）ロック・解除機構４６の動作に合わせて、突出部材４９１が突出するように構成されている。しかしながら、突出部材は、解除操作部４８の軸部により構成してもよく、この場合、軸部の第１方向の途中に、（本体側）ロック・解除機構４６の可動部４６６と接触する接触部を備えることで実施できる。
（１１）実施形態は、スティック型の電気掃除機における掃除機本体４と吸込体との接続に着目した発明を記載しているが、接続部を離間する離間機構に着目すると、スティック型、キャニスター型の掃除機に関係しない以下の発明が本明細書に記載されている。
つまり、第１接続体と第２接続体とが嵌合して接続される接続構造において、前記第１接続体と前記第２接続体との接続を固定するロック機構と、前記ロック機構の固定を解除する解除機構と、前記解除機構の解除に合わせて接続状態の前記第１接続体と前記第２接続体とを離間させる離間機構とを備える。
実施形態に当てはめると、第１接続体は掃除機本体４であり、第２接続体が吸込体（接続パイプ３）である。しかしながら、本発明に係る接続は、第１接続体が接続パイプであり、第２接続体が吸込具であってもよいし、第１接続体が掃除機本体であり、第２接続体が吸込具であってもよい。さらに、キャニスター型の電気掃除機では、第１接続体が手元操作具であり、第２接続体が接続パイプであってもよいし、第１接続体が接続パイプであり、第２接続体が吸込具であってもよい。 (10) In the separating mechanism 49 of the embodiment, the protruding member 491 is configured to protrude in accordance with the operation of the (main body side) locking/unlocking mechanism 46. However, the protruding member may be configured by the shaft portion of the release operation unit 48. In this case, this can be implemented by providing a contact portion that comes into contact with the movable portion 466 of the (main body side) locking/unlocking mechanism 46 midway in the first direction of the shaft portion.
(11) The embodiment describes an invention that focuses on the connection between the vacuum cleaner body 4 and the suction body in a stick-type vacuum cleaner. However, if we focus on the separation mechanism that separates the connection parts, the following inventions that are not related to stick-type or canister-type vacuum cleaners are described in this specification.
In other words, in a connection structure in which a first connecting body and a second connecting body are fitted together and connected, the connection structure includes a locking mechanism that fixes the connection between the first connecting body and the second connecting body, a release mechanism that releases the fixation of the locking mechanism, and a separation mechanism that separates the first connecting body and the second connecting body in a connected state in response to the release of the release mechanism.
In the embodiment, the first connection is the vacuum cleaner main body 4, and the second connection is the suction body (connection pipe 3). However, the connection according to the present invention may be such that the first connection is the connection pipe and the second connection is the suction tool, or the first connection is the vacuum cleaner main body and the second connection is the suction tool. Furthermore, in a canister type vacuum cleaner, the first connection may be the hand-operated tool and the second connection may be the connection pipe, or the first connection may be the connection pipe and the second connection may be the suction tool.
