Description

本発明は、レンジフード等における回転体装着装置に関する。 The present invention relates to a rotating body mounting device in a range hood or the like.

レンジフードは、排気を行うためのプロペラファン、シロッコファン、ターボファンなどの回転体や油や埃等を回収するためのグリスフィルタなどの回転体を備えている。これらの回転体をモータで回転させて、排気や排気に含まれる油の回収を図っている。
ファンやグリスフィルタなどの回転体は、調理によって発生した油煙に由来する油等が付着しやすいため、定期的な清掃が必要となる。そのため、汚れた回転体を清掃するためには、定期的に回転体を駆動シャフトから取り外す必要がある。
例えば、特許文献１のものは、スピンナーとよばれるネジの付いた取付けツマミを取り外すことにより、ボス筒と羽根車主体とを分離できるようになっている。しかし、特に羽根車が下向きに取り付けられているときは、スピンナーを外すと、ボス筒、羽根車主体、スピンナーの３部材が一挙にばらばらに外れ、部材が落下してしまいかねなかった。落下を防ぐためには、羽根車主体を片手で支えながら、スピンナーをもう片方の手で外す必要があり、作業性の悪い空間でそのような体勢を作業者に強いるものであった。
さらに、装着時にも、同様に羽根車主体を支えながら、スピンナーを回す必要があり作業性が悪かった。 The range hood is provided with a rotating body such as a propeller fan, a sirocco fan, and a turbo fan for exhausting, and a rotating body such as a grease filter for collecting oil and dust. These rotating bodies are rotated by a motor to recover the exhaust gas and the oil contained in the exhaust gas.
Since oil and the like derived from oil smoke generated by cooking easily adhere to rotating bodies such as fans and grease filters, regular cleaning is required. Therefore, in order to clean the dirty rotating body, it is necessary to periodically remove the rotating body from the drive shaft.
For example, in Patent Document 1, the boss cylinder and the impeller main body can be separated by removing a mounting knob with a screw called a spinner. However, especially when the impeller is mounted downward, if the spinner is removed, the three members of the boss cylinder, the impeller main body, and the spinner may come off at once, and the members may fall. In order to prevent the fall, it was necessary to support the impeller with one hand and remove the spinner with the other hand, which forced the worker to take such a posture in a space with poor workability.
Further, even at the time of mounting, it was necessary to turn the spinner while supporting the impeller main body in the same manner, and the workability was poor.

実施例１は、本発明をレンジフード１のグリスフィルタ（回転体）３０１に適用した実施例である。図１は、整流板を取り外したレンジフード１の底面側からの斜視図であり、レンジフード１の下面を覆う整流板を取り外した状態を図示している。回転体に相当するグリスフィルタ（回転体）３０１が取付装置３０２により装着されている。
グリスフィルタ（回転体）３０１の周囲には油分捕集部材としても機能するベルマウス（油分捕集部材）５が装着されている。 <Example 1>
Example 1 is an example in which the present invention is applied to the grease filter (rotating body) 301 of the range hood 1. FIG. 1 is a perspective view from the bottom surface side of the range hood 1 from which the straightening vane is removed, and shows a state in which the straightening vane covering the lower surface of the range hood 1 is removed. A grease filter (rotating body) 301 corresponding to a rotating body is mounted by the mounting device 302.
A bell mouth (oil collecting member) 5 that also functions as an oil collecting member is mounted around the grease filter (rotating body) 301.

回転体装着装置３０は、グリスフィルタ（回転体）３０１と取付装置３０２の少なくとも２つの部材から構成されている。取付装置３０２は、グリスフィルタ（回転体）３０１を挟んで両側に位置する部材であり、底面側からの斜視図である図１では、取付装置３０２の下側が見えている。取付装置３０２の両側から取付装置の動力軸着脱機構操作部３０３が突出している。 The rotating body mounting device 30 is composed of at least two members, a grease filter (rotating body) 301 and a mounting device 302. The mounting device 302 is a member located on both sides of the grease filter (rotating body) 301, and in FIG. 1, which is a perspective view from the bottom surface side, the lower side of the mounting device 302 is visible. The power shaft attachment / detachment mechanism operation unit 303 of the attachment device projects from both sides of the attachment device 302.

取付装置の動力軸着脱機構操作部３０３を押圧すると、回転体装着装置３０内に挿入されている動力軸（図示されていない）から回転体装着装置３０が外れる。具体的な構造は後述する実施例２の「１ 着脱装置 Ａ 動力軸着脱機構」と同様である。
グリスフィルタ（回転体）３０１と取付装置３０２とで構成される回転体装着装置３０が一体となったまま動力軸２０から外せるため、取付装置３０２を作業者が保持していれば、グリスフィルタ（回転体）３０１を特段支えなくともグリスフィルタ（回転体）３０１が外れて落ちてくることはない。 When the power shaft attachment / detachment mechanism operation unit 303 of the mounting device is pressed, the rotating body mounting device 30 is disengaged from the power shaft (not shown) inserted in the rotating body mounting device 30. The specific structure is the same as that of the "1 attachment / detachment device A power shaft attachment / detachment mechanism" of the second embodiment described later.
Since the rotating body mounting device 30 composed of the grease filter (rotating body) 301 and the mounting device 302 can be removed from the power shaft 20 while being integrated, if the worker holds the mounting device 302, the grease filter ( Even if the rotating body (rotating body) 301 is not particularly supported, the grease filter (rotating body) 301 will not come off and fall.

図２は、送風機ボックスの一部を説明のために取り除いたレンジフード１の上側からの斜視図 である。当該送風機ボックス内には、ファンケーシング６が設けられており、その内部にはファンとファンを駆動するモータが収められている。グリスフィルタ（回転体）３０１を駆動するグリスフィルタ駆動モータ（動力装置）４は、グリスフィルタ駆動モータ桟７上に固定されている。 FIG. 2 is a perspective view from above of the range hood 1 from which a part of the blower box is removed for explanation. A fan casing 6 is provided in the blower box, and a fan and a motor for driving the fan are housed in the fan casing 6. The grease filter drive motor (power device) 4 that drives the grease filter (rotating body) 301 is fixed on the grease filter drive motor crosspiece 7.

図３は、実施例１に係る（Ａ）グリスフィルタ駆動モータ（動力装置）４の斜視図、（Ｂ）グリスフィルタ（回転体）３０１及び取付装置３０２をグリスフィルタ駆動モータ（動力装置）４側から見た斜視図および（Ｃ）図３（Ｂ）の一点鎖線円内を拡大した斜視図である。 FIG. 3 is a perspective view of (A) the grease filter drive motor (power device) 4 according to the first embodiment, and (B) the grease filter (rotating body) 301 and the mounting device 302 are mounted on the grease filter drive motor (power device) 4 side. It is a perspective view seen from above and (C) is an enlarged perspective view of the inside of the alternate long and short dash line circle of FIG. 3 (B).

図３（Ａ）に記載のグリスフィルタ駆動モータ（動力装置）４の動力軸２０は、図３（Ｂ）および（Ｃ）に描かれた動力軸挿入孔３０５に挿入される。そして、動力軸２０に設けられている一対の駆動ピン２０１が動力軸挿入孔３０５の入り口付近に設けられた駆動ピン受入溝３０６に嵌合する。駆動ピン受入溝３０６は、複数対設けられており、動力軸２０がどのような周方向で動力軸挿入孔３０５に入れられても、嵌合できるように構成されている。 The power shaft 20 of the grease filter drive motor (power device) 4 shown in FIG. 3 (A) is inserted into the power shaft insertion hole 305 drawn in FIGS. 3 (B) and 3 (C). Then, the pair of drive pins 201 provided on the power shaft 20 are fitted into the drive pin receiving groove 306 provided near the entrance of the power shaft insertion hole 305. A plurality of pairs of drive pin receiving grooves 306 are provided so that the power shaft 20 can be fitted even if the power shaft 20 is inserted into the power shaft insertion hole 305 in any circumferential direction.

図３（Ｂ）に示されているように、取付装置３０２からは、取付装置の回転体着脱機構操作部３０７１が一対設けられており、また、一対の回転体押圧ストッパー３０７２がグリスフィルタ（回転体）３０１の上面に飛び出ている。また、グリスフィルタ（回転体）３０１の周囲にはベルマウス（油分捕集部材）５が配置されており、後述するように油分捕集部材として機能する。 As shown in FIG. 3B, the mounting device 302 is provided with a pair of rotating body attachment / detachment mechanism operation units 3071 of the mounting device, and a pair of rotating body pressing stoppers 3072 are grease filters (rotation). Body) It pops out on the upper surface of 301. Further, a bell mouth (oil collecting member) 5 is arranged around the grease filter (rotating body) 301, and functions as an oil collecting member as described later.

図４は、実施例１に係る回転体装着装置３０の（Ａ）正面図、（Ｂ）断面図、（Ｃ）回転体取り外し時の、回転体押圧ストッパー３０７２の位置を示す断面図とグリスフィルタ（回転体）３０１の取付装置挿入孔３０１１との位置関係を示す概念図を示す。
回転体装着装置３０は、図４（Ａ）～（Ｃ）のように、グリスフィルタ（回転体）３０１と取付装置３０２の２つの構成部材の組立体である。
回転体着脱機構３０７は、取付装置の回転体着脱機構操作部３０７１と回転体押圧ストッパー３０７２とで構成され、清掃等のため、回転体装着装置３０の構成部材であるグリスフィルタ（回転体）３０１を取付装置３０２から取り外すときには取付装置の回転体着脱機構操作部３０７１を押圧する。 FIG. 4 is a front view (A), a cross-sectional view (B), and (C) a cross-sectional view showing the position of the rotating body pressing stopper 3072 when the rotating body is removed, and a grease filter of the rotating body mounting device 30 according to the first embodiment. A conceptual diagram showing a positional relationship between the (rotating body) 301 and the mounting device insertion hole 3011 is shown.
As shown in FIGS. 4A to 4C, the rotating body mounting device 30 is an assembly of two components, a grease filter (rotating body) 301 and a mounting device 302.
The rotating body attachment / detachment mechanism 307 is composed of a rotating body attachment / detachment mechanism operation unit 3071 of the attachment device and a rotating body pressing stopper 3072, and is a grease filter (rotating body) 301 which is a constituent member of the rotating body attaching device 30 for cleaning and the like. When removing from the mounting device 302, the rotating body attachment / detachment mechanism operation unit 3071 of the mounting device is pressed.

取付装置の回転体着脱機構操作部３０７１を押圧する前の状態を示す図４（Ｂ）の状態において、取付装置の回転体着脱機構操作部３０７１を押圧すると、図４（Ｃ）のように回転体押圧ストッパー３０７２が取付装置３０２内に移動し、取付装置３０２内に完全に収まるように構成されている。回転体押圧ストッパー３０７２の移動機構については図示されていないが、取付装置の回転体着脱機構操作部３０７１と回転体押圧ストッパー３０７２がリンク機構により連結されているものや、取付装置の回転体着脱機構操作部３０７１の操作に基づき作動する電磁リレーを設けて回転体押圧ストッパー３０７２が移動するものなど移動機構の種類は問わない。 In the state of FIG. 4B showing the state before pressing the rotating body attachment / detachment mechanism operation unit 3071 of the mounting device, when the rotating body attachment / detachment mechanism operation unit 3071 of the mounting device is pressed, it rotates as shown in FIG. 4C. The body pressing stopper 3072 is configured to move into the mounting device 302 and completely fit within the mounting device 302. Although the moving mechanism of the rotating body pressing stopper 3072 is not shown, the rotating body attaching / detaching mechanism operation unit 3071 of the mounting device and the rotating body pressing stopper 3072 are connected by a link mechanism, or the rotating body attaching / detaching mechanism of the mounting device. The type of the moving mechanism is not limited, such as one in which an electromagnetic relay that operates based on the operation of the operation unit 3071 is provided and the rotating body pressing stopper 3072 moves.

取付装置の回転体着脱機構操作部３０７１の操作により回転体押圧ストッパー３０７２が取付装置３０２内に完全に収まった状態になると、図４（Ｃ）のように、グリスフィルタ（回転体）３０１の中央に設けられた取付装置挿入孔３０１１から取付装置３０２が抜ける状態となる。
グリスフィルタ（回転体）３０１の取付装置３０２への取り付けは、この逆を行えばよい。 When the rotating body pressing stopper 3072 is completely contained in the mounting device 302 by the operation of the rotating body attachment / detachment mechanism operation unit 3071 of the mounting device, the center of the grease filter (rotating body) 301 is as shown in FIG. 4 (C). The mounting device 302 is pulled out from the mounting device insertion hole 3011 provided in the above.
The grease filter (rotating body) 301 may be attached to the attachment device 302 in the reverse order.

取付装置３０２には、動力軸２０が、図４（Ａ）の動力軸挿入孔３０５側から挿入され、取付装置３０２は、グリスフィルタ（回転体）３０１を基準として、取付装置３０２に動力軸２０を挿入しない側に、取付装置３０２を動力軸２０と着脱する取付装置の動力軸着脱機構操作部３０３が設けられていることが分かる。
このような位置に取付装置の動力軸着脱機構操作部３０３があると、図１のように、レンジフード１の下側から簡単に手が届くようになる。
動力軸２０が水平に設けられているレンジフード１であっても、簡単に取付装置の動力軸着脱機構操作部３０３に手が届く。 The power shaft 20 is inserted into the mounting device 302 from the power shaft insertion hole 305 side of FIG. 4A, and the mounting device 302 is connected to the mounting device 302 with the grease filter (rotating body) 301 as a reference. It can be seen that the power shaft attachment / detachment mechanism operation unit 303 of the attachment device for attaching / detaching the attachment device 302 to / from the power shaft 20 is provided on the side where the attachment device 302 is not inserted.
When the power shaft attachment / detachment mechanism operation unit 303 of the mounting device is located at such a position, it can be easily reached from the lower side of the range hood 1 as shown in FIG.
Even if the range hood 1 is provided with the power shaft 20 horizontally, the power shaft attachment / detachment mechanism operation unit 303 of the mounting device can be easily reached.

また、取付装置３０２は、グリスフィルタ（回転体）３０１を基準として、取付装置３０２に動力軸２０を挿入する側に、取付装置の回転体着脱機構操作部３０７１を有している。
このような位置に、取付装置の回転体着脱機構操作部３０７１があると、回転体装着装置３０を動力軸２０から取り外した後でないと、グリスフィルタ（回転体）３０１を取付装置３０２から取り外せない。図１からも分かるように、取付装置の回転体着脱機構操作部３０７１は、レンジフード１の下から見えず手が届かない位置にあり、作業者が誤って取付装置の回転体着脱機構操作部３０７１を操作することができないようになっている。
グリスフィルタ（回転体）３０１を取付装置３０２から取り外せるようにしたのは、取り外すことでグリスフィルタ（回転体）３０１を清掃しやすくするためである。また、汚れたときに使い捨てタイプのグリスフィルタ（回転体）３０１を使用するときには、取付装置の回転体着脱機構操作部３０７１があるので、簡単に交換することができる。 Further, the mounting device 302 has a rotating body attachment / detachment mechanism operation unit 3071 of the mounting device on the side where the power shaft 20 is inserted into the mounting device 302 with reference to the grease filter (rotating body) 301.
If the rotating body attachment / detachment mechanism operation unit 3071 of the mounting device is located at such a position, the grease filter (rotating body) 301 cannot be removed from the mounting device 302 until after the rotating body mounting device 30 has been removed from the power shaft 20. .. As can be seen from FIG. 1, the rotating body attachment / detachment mechanism operation unit 3071 of the mounting device is located in a position that cannot be seen and reached from under the range hood 1, and the operator mistakenly makes a mistake in the rotating body attachment / detachment mechanism operation unit of the mounting device. It is not possible to operate 3071.
The reason why the grease filter (rotating body) 301 can be removed from the mounting device 302 is that the grease filter (rotating body) 301 can be easily cleaned by removing it. Further, when the disposable type grease filter (rotating body) 301 is used when it becomes dirty, it can be easily replaced because there is a rotating body attachment / detachment mechanism operation unit 3071 of the mounting device.

実施例１においては、回転体をグリスフィルタ（回転体）３０１として説明したが、レンジフード１に使用されるファンに用いてもよい。また、本発明は、レンジフード以外の回転体においても使用できる汎用的な技術である。以下の実施例においても同様である。 In the first embodiment, the rotating body has been described as a grease filter (rotating body) 301, but it may be used for a fan used in the range hood 1. Further, the present invention is a general-purpose technique that can be used in a rotating body other than a range hood. The same applies to the following examples.

（油捕集装置）
図１および図３（Ｂ）に図示されたベルマウス（油分捕集部材）５は、グリスフィルタ（回転体）３０１から遠心力で飛ぶ油を捕集できるように、円環状の溝部を有しており油分捕集部材としても機能する。溜まった油は、ベルマウス（油分捕集部材）５を外すだけで、簡単に廃棄することができる。
回転体が、ファンの場合も、ファンから遠心力で飛ぶ油を捕集する油分捕集部材を設けてもよい。また、ファンのケーシング等から垂れてくる油を捕集する油分捕集部材を設けてもよい。
どの部材から油が垂れるか、そして、油が垂れてくる位置等により油分捕集部材の形状や設置位置は適宜変更可能である。
油分捕集部材は、ベルマウス（油分捕集部材）５に限らず、様々なものが本発明に包含される。また、油を排出する排出管を油分捕集部材に設けてもよい。
いずれにせよ、油が回転体に付着する環境下では、油分捕集部材を設けることで、油の処理を簡単に行うことができる。 (Oil collector)
The bell mouth (oil collecting member) 5 illustrated in FIGS. 1 and 3B has an annular groove portion so that oil flying by centrifugal force can be collected from the grease filter (rotating body) 301. It also functions as a grease collecting member. The accumulated oil can be easily disposed of by simply removing the bell mouth (oil collecting member) 5.
Even if the rotating body is a fan, an oil collecting member that collects oil flying from the fan by centrifugal force may be provided. Further, an oil collecting member may be provided to collect the oil dripping from the casing of the fan or the like.
The shape and installation position of the oil collecting member can be appropriately changed depending on which member the oil drips from and the position where the oil drips.
The oil collecting member is not limited to the bell mouth (oil collecting member) 5, and various members are included in the present invention. Further, a discharge pipe for discharging oil may be provided in the oil collecting member.
In any case, in an environment where oil adheres to the rotating body, the oil can be easily treated by providing the oil collecting member.

＜実施例２＞
実施例２は、レンジフード１に使用されるグリスフィルタ（回転体）３０１を回転体とした実施の態様である。実施例１と異なるのは、取付装置３０２が、着脱装置４０と回転体押さえ装置５０にさらに分離できるようになっていることである。
図５には、実施例２に係る（Ａ）グリスフィルタ駆動モータ（動力装置）４の正面図、（Ｂ）回転体装着装置３０の正面図、（Ｃ）回転体装着装置３０の回転体押さえ装置５０を外した分解正面図、（Ｄ）回転体装着装置３０の回転体押さえ装置５０およびグリスフィルタ（回転体）３０１を外した分解正面図が示されている。 <Example 2>
The second embodiment is an embodiment in which the grease filter (rotating body) 301 used for the range hood 1 is used as a rotating body. The difference from the first embodiment is that the attachment device 302 can be further separated into the attachment / detachment device 40 and the rotating body holding device 50.
5A and 5B show a front view of (A) a grease filter drive motor (power device) 4 according to a second embodiment, (B) a front view of a rotating body mounting device 30, and (C) a rotating body holding device of the rotating body mounting device 30. An exploded front view with the device 50 removed, and (D) an exploded front view with the rotating body holding device 50 and the grease filter (rotating body) 301 removed from the rotating body mounting device 30 are shown.

図５（Ａ）には、後述する「１ 着脱装置 Ａ 動力軸着脱機構」で説明するように、動力軸着脱機構の構成部材である第１および第２動力軸保持レバー（４０３、４０４）によって保持される動力軸２０の縮径部２０２が示されている。
動力軸２０は、図５（Ｂ）のボス筒動力軸挿入孔４３３から挿入され、動力軸２０に回転体装着装置３０が装着される。 FIG. 5A shows the first and second power shaft holding levers (403, 404), which are constituent members of the power shaft attachment / detachment mechanism, as described in “1 Attachment / detachment device A power shaft attachment / detachment mechanism” described later. The reduced diameter portion 202 of the held power shaft 20 is shown.
The power shaft 20 is inserted through the boss cylinder power shaft insertion hole 433 of FIG. 5B, and the rotating body mounting device 30 is mounted on the power shaft 20.

図５（Ｂ）には、動力軸２０は示していないが、図５（Ｂ）の着脱装置の動力軸着脱機構操作部４０１を操作することで、回転体装着装置３０（回転体押さえ装置５０、グリスフィルタ（回転体）３０１および着脱装置４０の３つの部材で構成される）が一体となって、動力軸２０から取り外せるようになっている。 Although the power shaft 20 is not shown in FIG. 5B, by operating the power shaft attachment / detachment mechanism operation unit 401 of the attachment / detachment device of FIG. 5B, the rotating body mounting device 30 (rotating body holding device 50) can be operated. , A grease filter (rotating body) 301 and three members of the attachment / detachment device 40) are integrated and can be removed from the power shaft 20.

図５（Ｃ）のように回転体装着装置３０を動力軸２０から取り外した後、回転体押さえ装置の回転体着脱機構操作部５０１１を操作することで、グリスフィルタ（回転体）３０１を押さえていた回転体押さえ装置５０が外れ、グリスフィルタ（回転体）３０１が取り外せる状態となる。 After removing the rotating body mounting device 30 from the power shaft 20 as shown in FIG. 5C, the grease filter (rotating body) 301 is pressed by operating the rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device. The rotating body holding device 50 is removed, and the grease filter (rotating body) 301 can be removed.

図５（Ｄ）のように最後に、グリスフィルタ（回転体）３０１を着脱装置４０から取り外すと、回転体装着装置３０を構成する３つの部材がすべてバラバラになる。 Finally, when the grease filter (rotating body) 301 is removed from the attachment / detachment device 40 as shown in FIG. 5D, all three members constituting the rotating body mounting device 30 are separated.

図５（Ｂ）からも分かるように、グリスフィルタ（回転体）３０１を基準として、回転体装着装置３０に動力軸２０を挿入する側に回転体押さえ装置の回転体着脱機構操作部５０１１が設けられており、これを操作することでグリスフィルタ（回転体）３０１を回転体装着装置３０から着脱することができるようになっている。
レンジフード１において、回転体装着装置３０が取り付けられた状態では、グリスフィルタ（回転体）３０１が邪魔になり、回転体押さえ装置の回転体着脱機構操作部５０１１を操作することができないことは、実施例１と同様である。
着脱装置の動力軸着脱機構操作部４０１は、着脱装置４０に設けられており、これを操作すると、回転体装着装置３０全体が動力軸２０から離脱し、グリスフィルタ（回転体）３０１、着脱装置４０および回転体押さえ装置５０の３つの部材が一体となって取り外せる。
図５（Ｂ）の回転体装着装置３０は、レンジフード１から整流板を取り外すだけで、着脱装置の動力軸着脱機構操作部４０１が、作業者から見える位置になるように配置されており、簡単に操作できるように構成されている。
As can be seen from FIG. 5B, the rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device is provided on the side where the power shaft 20 is inserted into the rotating body mounting device 30 with the grease filter (rotating body) 301 as a reference. By operating this, the grease filter (rotating body) 301 can be attached to and detached from the rotating body mounting device 30.
In the range hood 1, when the rotating body mounting device 30 is attached, the grease filter (rotating body) 301 becomes an obstacle and the rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device cannot be operated. It is the same as Example 1.
The power shaft attachment / detachment mechanism operation unit 401 of the attachment / detachment device is provided in the attachment / detachment device 40, and when this is operated, the entire rotating body mounting device 30 is separated from the power shaft 20, and the grease filter (rotating body) 301 and the attachment / detachment device are attached. The three members of the 40 and the rotating body holding device 50 can be removed as a unit.
In the rotating body mounting device 30 of FIG. 5B, the power shaft attachment / detachment mechanism operation unit 401 of the attachment / detachment device is arranged so as to be visible to the operator by simply removing the straightening vane from the range hood 1. It is configured for easy operation.

次いで、回転体装着装置３０の構造と機能を説明する。
１ 着脱装置
Ａ 動力軸着脱機構
図６は、実施例２に係る着脱装置４０の（Ａ）分解図、（Ｂ）ボス部材４３正面図である。着脱装置４０には、第１動力軸保持レバー４０３、第２動力軸保持レバー４０４および動力軸保持レバー付勢部材４０２で構成される動力軸着脱機構が収められている。そして、第１動力軸保持レバー４０３および第２動力軸保持レバー４０４は、それぞれ着脱装置の動力軸着脱機構操作部４０１、保持レバー動力軸挿入孔４０５および動力軸当接保持部４０７を備えている。
図６（Ａ）を参照されたい。着脱装置下カバー４１内には、サポートカバー４２が収められている。サポートカバー４２の上に第１動力軸保持レバー４０３および第２動力軸保持レバー４０４が摺動自在に設けられている。 Next, the structure and function of the rotating body mounting device 30 will be described.
1 Detachment device A Power shaft attachment / detachment mechanism FIG. 6 is an exploded view (A) and a front view of (B) a boss member 43 of the attachment / detachment device 40 according to the second embodiment. The attachment / detachment device 40 includes a power shaft attachment / detachment mechanism including a first power shaft holding lever 403, a second power shaft holding lever 404, and a power shaft holding lever urging member 402. The first power shaft holding lever 403 and the second power shaft holding lever 404 each include a power shaft attachment / detachment mechanism operating portion 401, a holding lever power shaft insertion hole 405, and a power shaft contact holding portion 407 of the attachment / detachment device. ..
See FIG. 6 (A). The support cover 42 is housed in the attachment / detachment device lower cover 41. A first power shaft holding lever 403 and a second power shaft holding lever 404 are slidably provided on the support cover 42.

第１動力軸保持レバー４０３および第２動力軸保持レバー４０４には、付勢部材当接部４０６が設けられており、動力軸保持レバー付勢部材４０２の一端が当接するようになっている。動力軸保持レバー付勢部材４０２の他端はボス部材４３に当接している（図７参照）。 The first power shaft holding lever 403 and the second power shaft holding lever 404 are provided with an urging member contact portion 406 so that one end of the power shaft holding lever urging member 402 comes into contact with the first power shaft holding lever 403 and the second power shaft holding lever 404. The other end of the power shaft holding lever urging member 402 is in contact with the boss member 43 (see FIG. 7).

動力軸保持レバー付勢部材４０２は、第１および第２動力軸保持レバー（４０３、４０４）を図６中の矢印の方向に付勢しており、着脱装置の動力軸着脱機構操作部４０１が、ボス部材４３外に出るように付勢されている。
図７は、実施例２に係る動力軸２０と第１動力軸保持レバー４０３との当接関係を示すボス部材下面斜視図であり、第１動力軸保持レバー４０３が、動力軸２０の縮径部２０２を保持する様子が図示されている。説明のため、第２動力軸保持レバー４０４は、図示していない。第１および第２動力軸保持レバー（４０３、４０４）は、動力軸保持レバー付勢部材４０２により、動力軸２０の縮径部２０２を保持している。動力軸２０の縮径部２０２の形状は、図５（Ａ）を参照されたい。 The power shaft holding lever urging member 402 urges the first and second power shaft holding levers (403, 404) in the direction of the arrow in FIG. 6, and the power shaft attaching / detaching mechanism operating unit 401 of the attachment / detachment device is used. , Is urged to go out of the boss member 43.
FIG. 7 is a bottom perspective view of the boss member showing the contact relationship between the power shaft 20 and the first power shaft holding lever 403 according to the second embodiment, and the first power shaft holding lever 403 has a reduced diameter of the power shaft 20. The state of holding the part 202 is illustrated. For the sake of explanation, the second power shaft holding lever 404 is not shown. The first and second power shaft holding levers (403, 404) hold the reduced diameter portion 202 of the power shaft 20 by the power shaft holding lever urging member 402. Refer to FIG. 5A for the shape of the reduced diameter portion 202 of the power shaft 20.

前述したように、第１動力軸保持レバー４０３は、図示された矢印の方向へ動力軸保持レバー付勢部材４０２（第１動力軸保持レバー４０３の背面に隠れて、図示されていない）により付勢されており、動力軸当接保持部４０７が動力軸２０の縮径部２０２に当接し、保持していることが分かる。第２動力軸保持レバー４０４も同様である。
動力軸２０に回転体装着装置３０を取り付けた際には、動力軸２０の縮径部２０２が、第１および第２動力軸保持レバー（４０３、４０４）により両側から保持されることになる。
動力軸保持レバー付勢部材４０２の一例としてコイルバネが挙げられるが、同等の機能を有するものであれば、板バネ、ゴム等の弾性体等いかなるものでもよい。 As described above, the first power shaft holding lever 403 is attached by the power shaft holding lever urging member 402 (hidden behind the back surface of the first power shaft holding lever 403 and not shown) in the direction of the illustrated arrow. It can be seen that the power shaft contact holding portion 407 is in contact with and held by the reduced diameter portion 202 of the power shaft 20. The same applies to the second power shaft holding lever 404.
When the rotating body mounting device 30 is attached to the power shaft 20, the reduced diameter portion 202 of the power shaft 20 is held from both sides by the first and second power shaft holding levers (403, 404).

２ 回転体押さえ装置
図９は、実施例２に係る回転体押さえ装置５０の分解図である。最もグリスフィルタ（回転体）３０１側に、回転体押さえ装置ケース５０２が位置している。 2 Rotating body holding device FIG. 9 is an exploded view of the rotating body holding device 50 according to the second embodiment. The rotating body holding device case 502 is located on the most grease filter (rotating body) 301 side.

Ａ 回転体着脱機構
回転体着脱機構５０１は、詳しくは後述するがボス筒保持部材（クランプ作用のある棒バネ）５０１２でボス筒４３１（図示されていない）を挟んで保持している。保持を解除する場合、回転体押さえ装置の回転体着脱機構操作部５０１１が、ボス筒保持部材開口部５０１３に割入るように押し込まれることで、ボス筒保持部材（クランプ作用のある棒バネ）５０１２が開き、ボス筒４３１の保持が解除される。 A Rotating body attachment / detachment mechanism The rotating body attachment / detachment mechanism 501 is held by sandwiching the boss cylinder 431 (not shown) with a boss cylinder holding member (bar spring having a clamping action) 5012, which will be described in detail later. When the holding is released, the rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device is pushed so as to break into the boss cylinder holding member opening 5013, so that the boss cylinder holding member (bar spring having a clamping action) 5012 Opens, and the holding of the boss cylinder 431 is released.

ボス筒４３１は、着脱装置４０の上方に飛び出た部材であり、図６（Ｂ）のボス部材４３正面図において一点鎖線で示す領域にまたがっている部位である。図１０（Ａ）には実施例２に係るボス筒４３１の拡大図が示されている。また、図１０（Ｂ）は実施例２に係るボス筒４３１と回転体着脱機構５０１の保持関係を示す斜視図である。 The boss cylinder 431 is a member protruding above the attachment / detachment device 40, and is a portion straddling the region indicated by the alternate long and short dash line in the front view of the boss member 43 in FIG. 6B. FIG. 10A shows an enlarged view of the boss cylinder 431 according to the second embodiment. Further, FIG. 10B is a perspective view showing a holding relationship between the boss cylinder 431 and the rotating body attachment / detachment mechanism 501 according to the second embodiment.

ボス筒４３１のボス筒先端部４３１３側には、ボス筒拡径部４３１５が形成されており、駆動ピン受入溝４３１１が設けられている。そして、ボス筒拡径部４３１５の直下に、テーパー面４３１２が設けられている。ボス筒保持部材（クランプ作用のある棒バネ）５０１２がボス筒４３１を保持する場合に、図１０（Ｂ）に示すように、このテーパー面４３１２に当接するようにボス筒保持部材（クランプ作用のある棒バネ）５０１２が設けられており、ボス筒４３１を挟んで保持している。これは、実施例２における回転体着脱機構５０１の第１の機能である。ボス筒４３１が保持されることで、回転体押さえ装置５０を取り外さない限り、グリスフィルタ（回転体）３０１を取り外すことはできない。 A boss cylinder enlarged diameter portion 4315 is formed on the boss cylinder tip end portion 4313 side of the boss cylinder 431, and a drive pin receiving groove 4311 is provided. A tapered surface 4312 is provided directly below the boss cylinder enlarged diameter portion 4315. When the boss cylinder holding member (bar spring having a clamping action) 5012 holds the boss cylinder 431, as shown in FIG. 10B, the boss cylinder holding member (clamping action) abuts on the tapered surface 4312. A bar spring) 5012 is provided and holds the boss cylinder 431 in between. This is the first function of the rotating body attachment / detachment mechanism 501 in the second embodiment. By holding the boss cylinder 431, the grease filter (rotating body) 301 cannot be removed unless the rotating body holding device 50 is removed.

ボス筒保持部材（クランプ作用のある棒バネ）５０１２がテーパー面４３１２を挟持するため、その挟み付ける付勢力は、テーパー面４３１２で分力を生じ、図１０（Ｂ）の矢印で図示した方向に着脱装置４０のボス筒４３１を持ち上げ、回転体押さえ装置５０との間に挟まれたグリスフィルタ（回転体）３０１を、回転体押さえ装置５０に向けて押さえつける付勢部として作用する。
これが実施例２における回転体着脱機構５０１の第２の機能であり、グリスフィルタ（回転体）３０１がガタつかないように押さえつける付勢部としての機能を併せ持っている。第２の機能により、グリスフィルタ（回転体）３０１は、ガタつかなくなり、回転時の騒音や異音を抑制することができる。
第２の機能を奏するのに好適なテーパー面の角度θ（図１０（Ａ）参照）は、９５°～１３５°である。 Since the boss cylinder holding member (bar spring having a clamping action) 5012 sandwiches the tapered surface 4312, the urging force for sandwiching the boss cylinder holding member (bar spring having a clamping action) generates a component force on the tapered surface 4312 in the direction shown by the arrow in FIG. 10 (B). The boss cylinder 431 of the attachment / detachment device 40 is lifted, and the grease filter (rotating body) 301 sandwiched between the boss cylinder 431 and the rotating body holding device 50 acts as an urging portion for pressing the rotating body holding device 50.
This is the second function of the rotating body attachment / detachment mechanism 501 in the second embodiment, and also has a function as an urging portion for pressing the grease filter (rotating body) 301 so as not to rattle. With the second function, the grease filter (rotating body) 301 does not rattle, and noise and abnormal noise during rotation can be suppressed.
The angle θ of the tapered surface (see FIG. 10A) suitable for performing the second function is 95 ° to 135 °.

図９、図１０および図１１を用いて装着時の部材間の関係を説明する。
図１１は、実施例２に係るボス筒保持部材（クランプ作用のある棒バネ）５０１２とボス筒先端部４３１３との関係を示す概念図である。
図９で示したサポート部材５０３は、回転体着脱機構５０１を構成するボス筒保持部材（クランプ作用のある棒バネ）５０１２および回転体押さえ装置の回転体着脱機構操作部５０１１を保持しており、回転体押さえ装置ケース５０２内で外れないように押さえて保持する部材である。
図９で示した回転体押さえ装置５０のケースのボス筒挿入孔５０２１からグリスフィルタ（回転体）３０１を取り付けた着脱装置４０のボス筒４３１を挿入することで、回転体押さえ装置５０は装着される。ボス筒先端部４３１３が、ケースのボス筒挿入孔５０２１から挿入されると、まずボス筒保持部材（クランプ作用のある棒バネ）５０１２に当接する。次いで、さらにボス筒先端部４３１３を押し込むとサポート部材のボス筒挿入孔５０３１を通り、上部カバーのボス筒挿入孔５０４１よりボス筒先端部４３１３が回転体押さえ装置５０からわずかに出る。この状態は、図５（Ｂ）に図示したとおりである。 The relationship between the members at the time of mounting will be described with reference to FIGS. 9, 10 and 11.
FIG. 11 is a conceptual diagram showing the relationship between the boss cylinder holding member (bar spring having a clamping action) 5012 and the boss cylinder tip portion 4313 according to the second embodiment.
The support member 503 shown in FIG. 9 holds a boss cylinder holding member (bar spring having a clamping action) 5012 constituting the rotating body attaching / detaching mechanism 501 and a rotating body attaching / detaching mechanism operating unit 5011 of the rotating body holding device. It is a member that presses and holds the rotating body holding device case 502 so as not to come off.
The rotating body holding device 50 is mounted by inserting the boss cylinder 431 of the attachment / detachment device 40 to which the grease filter (rotating body) 301 is attached from the boss cylinder inserting hole 5021 of the case of the rotating body holding device 50 shown in FIG. Ru. When the boss cylinder tip portion 4313 is inserted from the boss cylinder insertion hole 5021 of the case, it first comes into contact with the boss cylinder holding member (bar spring having a clamping action) 5012. Next, when the boss cylinder tip portion 4313 is further pushed in, the boss cylinder tip portion 4313 slightly exits from the rotating body holding device 50 through the boss cylinder insertion hole 5031 of the support member and from the boss cylinder insertion hole 5041 of the upper cover. This state is as illustrated in FIG. 5 (B).

ボス筒保持部材（クランプ作用のある棒バネ）５０１２が、どのようにボス筒４３１に装着されるかを詳述する。
図１１に示したように、実施例２において、ボス筒保持部材（クランプ作用のある棒バネ）５０１２は、断面が円形の棒バネである。着脱装置４０に装着する前であって且つ、回転体押さえ装置の回転体着脱機構操作部５０１１（図１０（Ｂ））を操作していない状態において、 ボス筒保持部材（クランプ作用のある棒バネ）５０１２断面となる円形の下端をつないだ径ａは、ボス筒先端部４３１３の径ｂよりわずかに広く設計されている。 How the boss cylinder holding member (bar spring having a clamping action) 5012 is mounted on the boss cylinder 431 will be described in detail.
As shown in FIG. 11, in the second embodiment, the boss cylinder holding member (bar spring having a clamping action) 5012 is a bar spring having a circular cross section. Before mounting on the attachment / detachment device 40, and in a state where the rotating body attachment / detachment mechanism operation unit 5011 (FIG. 10B) of the rotating body holding device is not operated, the boss cylinder holding member (bar spring having a clamping action) ) The diameter a connecting the lower ends of the circle having the 5012 cross section is designed to be slightly wider than the diameter b of the tip portion 4313 of the boss cylinder.

ボス筒保持部材（クランプ作用のある棒バネ）５０１２は断面が円形であり、円形のボス筒保持部材（クランプ作用のある棒バネ）５０１２が、 ボス筒先端部４３１３の曲面に当たり、そのまま回転体押さえ装置５０にボス筒４３１を挿入し続けることで押し広げられてボス筒拡径部４３１５と当接する。回転体押さえ装置の回転体着脱機構操作部５０１１をボス筒保持部材開口部５０１３に押し込んで操作しなくとも、回転体押さえ装置５０を着脱装置４０に向けて押し込み続けると、ボス筒拡径部４３１５に沿ってボス筒保持部材（クランプ作用のある棒バネ）５０１２がさらに拡径し、ボス筒４３１のテーパー面４３１２でボス筒保持部材（クランプ作用のある棒バネ）５０１２により保持がなされる。
上述したように径ａ＞径ｂの関係にすると、装着時に、回転体押さえ装置の回転体着脱機構操作部５０１１を操作する必要なく、回転体押さえ装置５０を着脱装置４０に向けて押し込むだけで装着が完了するため、装着が楽に行える。 The boss cylinder holding member (bar spring having a clamping action) 5012 has a circular cross section, and the circular boss cylinder holding member (bar spring having a clamping action) 5012 hits the curved surface of the boss cylinder tip portion 4313 and holds the rotating body as it is. By continuing to insert the boss cylinder 431 into the device 50, it is expanded and comes into contact with the boss cylinder enlarged diameter portion 4315. Even if the rotating body holding device operation unit 5011 of the rotating body holding device is not pushed into the boss cylinder holding member opening 5013 to be operated, when the rotating body holding device 50 is continuously pushed toward the attachment / detachment device 40, the boss cylinder enlarged diameter portion 4315 The boss cylinder holding member (bar spring having a clamping action) 5012 is further expanded in diameter along the above, and is held by the boss cylinder holding member (bar spring having a clamping action) 5012 on the tapered surface 4312 of the boss cylinder 431.
As described above, if the diameter a> diameter b is satisfied, it is not necessary to operate the rotating body attaching / detaching mechanism operation unit 5011 of the rotating body holding device at the time of mounting, and the rotating body holding device 50 is simply pushed toward the attaching / detaching device 40. Since the installation is completed, the installation can be done easily.

Ｂ 回転体を押さえつける付勢部
実施例２では、回転体着脱機構５０１に第１の機能と第２の機能を併せ持つようにしたが、本来回転体着脱機構５０１は、第１の機能を備えていればよく、第２の機能を併せ持つ必要はない。
また、グリスフィルタ（回転体）３０１を押さえつける付勢部としての機能（第２の機能）を、回転体着脱機構５０１と別に設けた付勢部によって与えてもよい。 B Bouncer for pressing the rotating body In Example 2, the rotating body attachment / detachment mechanism 501 has both the first function and the second function, but the rotating body attachment / detachment mechanism 501 originally has the first function. It suffices, and it is not necessary to have the second function at the same time.
Further, the function (second function) as the urging portion for pressing the grease filter (rotating body) 301 may be provided by the urging portion provided separately from the rotating body attachment / detachment mechanism 501.

図１２は、実施例２に係る付勢部の様々な態様を示す概念図である。

FIG. 12A is a cushion type. A cushion is provided on the lower surface of the rotating body holding device 50, and when the rotating body holding device 50 is attached, it functions as an urging portion for holding the grease filter (rotating body) 301.

図１２（Ｂ）は、テコ式であり、着脱装置４０の上面にはテコ持ち上げ突起が設けてあり、回転体押さえ装置５０に設けられたテコの力点を持ち上げるようになっている。支点を挟んで力点と逆側にある作用点は、グリスフィルタ（回転体）３０１を押さえつける付勢部として機能する。
以上の、付勢部の態様は、一例を示すものであって、磁石を使用して磁力により付勢するなど、付勢部として機能するものであればいかなるものでもよく、上記例に限られるものではない。 FIG. 12B is a lever type, and a lever lifting protrusion is provided on the upper surface of the attachment / detachment device 40 to lift the power point of the lever provided on the rotating body holding device 50. The point of action on the opposite side of the fulcrum from the point of force functions as an urging portion that presses the grease filter (rotating body) 301.
The above-mentioned mode of the urging portion is an example, and may be any one that functions as an urging portion, such as urging by magnetic force using a magnet, and is limited to the above example. It's not a thing.

図１３は、実施例２に係る着脱装置４０、グリスフィルタ（回転体）３０１、回転体押さえ装置５０の装着関係を示す分解図である。グリスフィルタ（回転体）３０１の着脱装置挿入孔３０１５からボス筒４３１が出ており、グリスフィルタ（回転体）３０１の突起挿入孔（係合機構）３０１６から、着脱装置４０の突起（被係合機構）４３４が飛び出している。この飛び出た突起（被係合機構）４３４を収める円環溝５０５が、回転体押さえ装置５０のグリスフィルタ（回転体）３０１側の面に設けられている。円環溝５０５は、方向に無関係に突起（被係合機構）４３４を収められる点で有利な作用を有する。
しかし、強固にグリスフィルタ（回転体）３０１を回り止めしたい場合は、突起（被係合機構）４３４がちょうど収まる凹部を回転体押さえ装置５０に設けてもよい。 C Circular groove of the rotating body holding device As described in "1 Attaching / detaching device B Engagement mechanism between the rotating body and the attaching / detaching device (boss member)", in the second embodiment, the grease filter (rotating body) 301 is provided with the grease filter (rotating body) 301. A protrusion insertion hole (engagement mechanism) 3016 is provided, and the protrusion (engaged mechanism) 434 on the upper surface of the boss member 43 is configured to be inserted.
FIG. 13 is an exploded view showing the mounting relationship of the attachment / detachment device 40, the grease filter (rotating body) 301, and the rotating body holding device 50 according to the second embodiment. The boss cylinder 431 protrudes from the attachment / detachment device insertion hole 3015 of the grease filter (rotating body) 301, and the protrusion (engaged) of the attachment / detachment device 40 comes out from the protrusion insertion hole (engagement mechanism) 3016 of the grease filter (rotating body) 301. Mechanism) 434 is popping out. An annular groove 505 that accommodates the protruding protrusion (engaged mechanism) 434 is provided on the surface of the rotating body holding device 50 on the grease filter (rotating body) 301 side. The annular groove 505 has an advantageous effect in that the protrusion (engaged mechanism) 434 can be accommodated regardless of the direction.
However, if it is desired to firmly stop the grease filter (rotating body) 301 from rotating, the rotating body holding device 50 may be provided with a recess in which the protrusion (engaged mechanism) 434 is just accommodated.

さらに、前述したように、突起（被係合機構）４３４は、回転体押さえ装置５０に設けてもよく、この場合、円環溝は着脱装置４０のグリスフィルタ（回転体）３０１の装着面に設けられることになる。
そして、着脱装置４０に設けられた突起（被係合機構）４３４の配置は、同じ円周上に配置するなど規則性をもって配置されてもよいが、規則性なく配置されていてもよい。その場合、グリスフィルタ（回転体）３０１を着脱装置４０に装着した際に、突起挿入孔（係合機構）３０１６から飛び出た突起（被係合機構）４３４の配置に対応させて、それを収める回転体押さえ装置５０底面の円環溝５０５等の配置が決まる。
また、グリスフィルタ（回転体）３０１に突起からなる係合機構を設け、前記突起を収める円環溝や突起をちょうど収める凹部を着脱装置４０および／または回転体押さえ装置５０に設けてもよい。

以上のように、様々な態様が本発明に包含される。 Further, as described above, the protrusion (engaged mechanism) 434 may be provided on the rotating body holding device 50, and in this case, the annular groove is formed on the mounting surface of the grease filter (rotating body) 301 of the attachment / detachment device 40. It will be provided.
The protrusions (engaged mechanism) 434 provided on the attachment / detachment device 40 may be arranged with regularity such as arrangement on the same circumference, but may be arranged without regularity.

＜実施例４＞
実施例４は、実施例２の回転体押さえ装置５０の別態様である。
図１５は、実施例４に係る回転体押さえ装置５０の（Ａ）斜視図、（Ｂ）上部カバー５０４を取り除いた斜視図を示したものである。
図１５（Ａ）に示されたように、回転体押さえ装置５０からは、回転体押さえ装置の回転体着脱機構操作部５０１１が飛び出している。
なお、回転体押さえ装置の回転体着脱機構操作部５０１１は、実施例４では、側面から飛び出しているように構成したが、操作が可能な部位であればどこでもよく、本発明においては回転体押さえ装置５０の頂部から飛び出していてもよい。また、回転体押さえ装置の回転体着脱機構操作部５０１１が操作できるのであれば飛び出している必要もない。取付装置の動力軸着脱機構操作部などの他の操作部についても同様である。 <Example 4>
The fourth embodiment is another aspect of the rotating body holding device 50 of the second embodiment.
FIG. 15 shows a perspective view of the rotating body holding device 50 according to the fourth embodiment (A) and a perspective view of the rotating body holding device 50 with the upper cover 504 removed.
As shown in FIG. 15A, the rotating body attaching / detaching mechanism operation unit 5011 of the rotating body holding device protrudes from the rotating body holding device 50.
In the fourth embodiment, the rotating body attachment / detachment mechanism operation unit 5011 of the rotating body pressing device is configured to protrude from the side surface, but any part that can be operated may be used, and in the present invention, the rotating body pressing device may be used. It may pop out from the top of the device 50. Further, if the rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device can be operated, it is not necessary to pop out. The same applies to other operation units such as the power shaft attachment / detachment mechanism operation unit of the mounting device.

図１５（Ｂ）を参照されたい。回転体着脱機構５０１は、回転体押さえ装置の回転体着脱機構操作部５０１１を備えたボス筒保持レバー５０７とボス筒保持レバーの押圧バネ５０７１とで構成されている。ボス筒保持レバー５０７は一端に回転体押さえ装置の回転体着脱機構操作部５０１１が設けられ、その他端にボス筒保持レバーの押圧バネ５０７１が装着され、ボス筒保持レバーの押圧バネ５０７１により、矢印の方向にボス筒保持レバー５０７が付勢されており、ボス筒拡径部４３１５の直下位置（図１０参照）で、ボス筒保持レバーのボス筒当接部５０７３が、ボス筒保持レバーのボス筒挿入孔５０７２内に挿入されているボス筒４３１を押圧する。これにより、ボス筒４３１は保持されることとなる。ボス筒保持レバーのボス筒挿入孔５０７２は、真円ではなくボス筒保持レバー５０７の移動方向の径が長くなっている。真円だとボス筒拡径部４３１５とボス筒保持レバーのボス筒挿入孔５０７２の位置が一致したときしかボス筒４３１を抜くことができないため、回転体押さえ装置の回転体着脱機構操作部５０１１を動かす加減を調整するのが難しくなる。しかし、前記したように径が長くなっているため、押し込む加減を厳密に調整しなくとも、着脱装置４０から回転体押さえ装置５０を外すことができ、グリスフィルタ（回転体）３０１が取り外せる。 See FIG. 15 (B). The rotating body attachment / detachment mechanism 501 includes a boss cylinder holding lever 507 provided with a rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device, and a pressing spring 5071 of the boss cylinder holding lever. The boss cylinder holding lever 507 is provided with a rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device at one end, and a pressing spring 5071 of the boss cylinder holding lever is attached to the other end. The boss cylinder holding lever 507 is urged in the direction of The boss cylinder 431 inserted in the cylinder insertion hole 5072 is pressed. As a result, the boss cylinder 431 is held. The boss cylinder insertion hole 5072 of the boss cylinder holding lever is not a perfect circle but has a long diameter in the moving direction of the boss cylinder holding lever 507. If it is a perfect circle, the boss cylinder 431 can be pulled out only when the positions of the boss cylinder expansion portion 4315 and the boss cylinder insertion hole 5072 of the boss cylinder holding lever match. It becomes difficult to adjust the amount of movement. However, since the diameter is long as described above, the rotating body holding device 50 can be removed from the attachment / detachment device 40 without strictly adjusting the pushing amount, and the grease filter (rotating body) 301 can be removed.

＜実施例５＞
図１６は、実施例５に係る（Ａ）回転体装着装置３０の斜視図、（Ｂ）回転体押さえ装置５０を取り外した斜視図、（Ｃ）着脱装置４０の斜視図、（Ｄ）回転体押さえ装置５０をグリスフィルタ（回転体）３０１側から見た斜視図、（Ｅ）グリスフィルタ（回転体）３０１の拡大斜視図である。
図１６（Ａ）には、着脱装置４０のボス筒先端部４３１３が見えている。着脱装置４０、グリスフィルタ（回転体）３０１および回転体押さえ装置５０から構成される回転体装着装置３０が図示されている。 <Example 5>
16A and 16B are a perspective view of (A) the rotating body mounting device 30 according to the fifth embodiment, (B) a perspective view from which the rotating body holding device 50 is removed, (C) a perspective view of the attachment / detachment device 40, and (D) a rotating body. It is a perspective view which saw the holding device 50 from the side of the grease filter (rotating body) 301, and (E) is the enlarged perspective view of the grease filter (rotating body) 301.
In FIG. 16A, the tip portion 4313 of the boss cylinder of the attachment / detachment device 40 is visible. The rotating body mounting device 30 including the attachment / detachment device 40, the grease filter (rotating body) 301, and the rotating body holding device 50 is shown.

１ 回転体と着脱装置の取付構造
図１６（Ａ）の状態から、回転体押さえ装置５０を取り外した状態が図１６（Ｂ）である。グリスフィルタ（回転体）３０１には、掛合突起挿入孔（係合機構）３０１８（図１６（Ｅ））が設けられており、図１６(Ｂ)のように着脱装置４０に設けられている掛合突起（被係合機構）４３５が挿入されている。掛合突起（被係合機構）４３５は、図１６（Ｂ）および（Ｃ）で示すように、根元から先端がグリスフィルタ（回転体）３０１の中心に向かって曲がっている形状をしている。着脱装置４０にグリスフィルタ（回転体）３０１を装着した図１６（Ｂ）の状態では、掛合突起挿入孔（係合機構）３０１８のボス筒４３１側にすき間が空いていることが見て取れる。図１６（Ｅ）に示されているように、掛合突起挿入孔（係合機構）３０１８はグリスフィルタ（回転体）３０１の中心から最も離れた箇所にある掛合突起当接部３０１９に掛合突起（被係合機構）４３５が当接する。一対の掛合突起（被係合機構）４３５が掛合突起当接部３０１９で当接するため、装着時に掛合突起挿入孔（係合機構）３０１８に前記したようなすき間が生じるが、すき間に向けて掛合突起（被係合機構）４３５は動くことができない。 1 Mounting structure of rotating body and attachment / detachment device FIG. 16B shows a state in which the rotating body holding device 50 is removed from the state shown in FIG. 16A. The grease filter (rotating body) 301 is provided with an engagement protrusion insertion hole (engagement mechanism) 3018 (FIG. 16 (E)), and is provided in the attachment / detachment device 40 as shown in FIG. 16 (B). A protrusion (engaged mechanism) 435 is inserted. As shown in FIGS. 16B and 16C, the engaging projection (engaged mechanism) 435 has a shape in which the tip is bent toward the center of the grease filter (rotating body) 301 from the root. In the state of FIG. 16B in which the grease filter (rotating body) 301 is attached to the attachment / detachment device 40, it can be seen that there is a gap on the boss cylinder 431 side of the engagement protrusion insertion hole (engagement mechanism) 3018. As shown in FIG. 16E, the engagement projection insertion hole (engagement mechanism) 3018 is attached to the engagement projection contact portion 3019 at the position farthest from the center of the grease filter (rotating body) 301. Engagement mechanism) 435 comes into contact. Since the pair of engagement protrusions (engaged mechanism) 435 abut at the engagement protrusion contact portion 3019, the engagement protrusion insertion hole (engagement mechanism) 3018 has a gap as described above at the time of mounting, but the gap is formed toward the gap. The protrusion (engaged mechanism) 435 cannot move.

このように、グリスフィルタ（回転体）３０１に設けられた掛合突起挿入孔（係合機構）３０１８に、着脱装置４０に設けられた掛合突起（被係合機構）４３５が挿入されると、グリスフィルタ（回転体）３０１は回り止めされ回転方向に動くことができず、ガタつくことが無くなる。 In this way, when the engagement protrusion (engaged mechanism) 435 provided in the attachment / detachment device 40 is inserted into the engagement protrusion insertion hole (engagement mechanism) 3018 provided in the grease filter (rotating body) 301, the grease is applied. The filter (rotating body) 301 is stopped from rotating and cannot move in the rotation direction, so that it does not rattle.

掛合突起４３５は、図１６（Ｄ）で図示された回転体押さえ装置５０の掛合突起挿入部５０９に挿入された後、掛合突起掛合部５０８側に回転体押さえ装置５０を回動することで掛け合い、さらに強固に回り止めされる。 The engagement protrusion 435 is inserted into the engagement projection insertion portion 509 of the rotating body holding device 50 shown in FIG. 16 (D), and then the rotating body holding device 50 is rotated toward the engagement protrusion engaging portion 508 side to engage the engagement protrusion 435. , It is even more firmly stopped.

２ 回転体押さえ装置の回転体着脱機構
図１７は、実施例５に係る回転体押さえ装置５０の回転体着脱機構５０１の斜視図であり、この状態で本来装着されてなければならないグリスフィルタ（回転体）３０１を説明のため図示していない。この他、説明に不要な部材を回転体押さえ装置５０から省き、回転体押さえ装置５０の内部が分かるようになっている。
実施例５のボス筒４３１の形状は実施例２～実施例４と異なり、ボス筒拡径部４３１５がなく、円筒状である。また、ボス筒４３１には、側面に嵌合溝４３６が設けられている。嵌合溝４３６の形状は、図１６（Ｃ）に図示されている。
図１７の着脱装置４０のボス筒４３１に設けられた嵌合溝４３６に、回転体押さえ装置５０の着脱突起５１２が嵌合することで、着脱装置４０と回転体押さえ装置５０が固定され、着脱装置４０と回転体押さえ装置５０の間にグリスフィルタ（回転体）３０１が保持されることとなる。着脱突起５１２の形状は、図１８に示されている。 2 Rotating body attachment / detachment mechanism of the rotating body holding device FIG. 17 is a perspective view of the rotating body attaching / detaching mechanism 501 of the rotating body holding device 50 according to the fifth embodiment, and is a grease filter (rotation) that must be originally mounted in this state. Body) 301 is not shown for illustration. In addition, members unnecessary for explanation are omitted from the rotating body holding device 50 so that the inside of the rotating body holding device 50 can be seen.
The shape of the boss cylinder 431 of the fifth embodiment is different from that of the second to fourth embodiments, and is cylindrical without the boss cylinder enlarged diameter portion 4315. Further, the boss cylinder 431 is provided with a fitting groove 436 on the side surface. The shape of the fitting groove 436 is shown in FIG. 16 (C).
By fitting the attachment / detachment protrusion 512 of the rotating body holding device 50 into the fitting groove 436 provided in the boss cylinder 431 of the attaching / detaching device 40 of FIG. 17, the attachment / detachment device 40 and the rotating body holding device 50 are fixed and attached / detached. The grease filter (rotating body) 301 is held between the device 40 and the rotating body holding device 50. The shape of the removable protrusion 512 is shown in FIG.

図１７に図示されているように、着脱突起５１２は、リンク機構５１１で回転体押さえ装置の回転体着脱機構操作部５０１１につながっている。回転体押さえ装置の回転体着脱機構操作部５０１１には、図中の矢印の方向へ付勢する着脱突起付勢バネ５１３が設けられている。着脱突起付勢バネ５１３が矢印の方向へ付勢されることで、リンク機構５１１でつながれた着脱突起５１２が嵌合溝４３６へと付勢されていることが分かる。 As shown in FIG. 17, the attachment / detachment protrusion 512 is connected to the rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device by the link mechanism 511. The rotating body attachment / detachment mechanism operation unit 5011 of the rotating body holding device is provided with a attachment / detachment protrusion urging spring 513 for urging in the direction of the arrow in the drawing. It can be seen that the detachable protrusion 512 connected by the link mechanism 511 is urged to the fitting groove 436 by urging the detachable protrusion urging spring 513 in the direction of the arrow.

３ 回転体を押さえつける付勢部
実施例２では、図１０（Ｂ）に示したようにボス筒保持部材（クランプ作用のある棒バネ）５０１２がテーパー面４３１２を挟持するため、その挟み付ける付勢力は、テーパー面４３１２で分力を生じ、矢印で図示した方向、すなわち、グリスフィルタ（回転体）３０１を着脱装置４０と挟むように付勢部を構成した。 3 Energizing part that presses the rotating body In Example 2, as shown in FIG. 10B, the boss cylinder holding member (bar spring having a clamping action) 5012 sandwiches the tapered surface 4312, so that the urging force that sandwiches the boss cylinder holding member (bar spring) 5012. A component force is generated on the tapered surface 4312, and the urging portion is configured so as to sandwich the grease filter (rotating body) 301 with the attachment / detachment device 40 in the direction shown by the arrow.

実施例５ではそれとは異なり、ガタ防止突起５１５を設けることでグリスフィルタ（回転体）３０１を押さえつける付勢部を構成した。ガタ防止突起５１５は、図１６（Ｄ）に図示されているように、回転体押さえ装置５０のグリスフィルタ（回転体）３０１側の面に設けられている。図１８は、実施例５に掛る回転体押さえ装置５０の説明に不要な部材を取り外した状態の斜視図であり、ガタ防止突起５１５がガタ防止突起付勢バネ５１６を介して配設され矢印の方向へ付勢されている。これにより、ガタ防止突起５１５はグリスフィルタ（回転体）３０１を押さえつける付勢部として機能する。これにより、着脱装置４０と回転体押さえ装置５０との間に挟まれたグリスフィルタ（回転体）３０１が、ガタつくことが防止される。 In the fifth embodiment, unlike that, the biasing portion for pressing the grease filter (rotating body) 301 is configured by providing the backlash prevention protrusion 515. As shown in FIG. 16D, the backlash prevention protrusion 515 is provided on the surface of the rotating body holding device 50 on the grease filter (rotating body) 301 side. FIG. 18 is a perspective view of a state in which a member unnecessary for the explanation of the rotating body holding device 50 according to the fifth embodiment is removed, and the backlash prevention protrusion 515 is arranged via the backlash prevention protrusion urging spring 516 and is indicated by an arrow. Being urged in the direction. As a result, the backlash prevention protrusion 515 functions as an urging portion for pressing the grease filter (rotating body) 301. As a result, the grease filter (rotating body) 301 sandwiched between the attachment / detachment device 40 and the rotating body holding device 50 is prevented from rattling.

以上の実施例は、回転体をグリスフィルタ（回転体）３０１として説明したが、レンジフードに使用されるファンに用いてもよい。また、本発明は、レンジフード以外の回転体においても使用できる汎用的な技術である。 In the above embodiment, the rotating body has been described as a grease filter (rotating body) 301, but it may be used for a fan used in a range hood. Further, the present invention is a general-purpose technique that can be used in a rotating body other than a range hood.

（まとめ）
以上のように、本発明は、回転体および取付装置を含む回転体装着装置を一体として動力軸から着脱することができ、特にレンジフードのように高所に回転体がある場合、取り外し作業や取り付け作業がしやすくなった。
また、回転体を回転体装着装置から着脱する回転体着脱機構操作部は、通常手が届かない動力軸を挿入する側に設けているので、誤って回転体着脱機構操作部を操作し、回転体が分解し落下することが回避される。 (summary)
