Description

本発明は、良好なダンパー効果を発揮する画期的なヒンジ装置並びにヒンジ装置を用いた電子機器に関するものである。   The present invention relates to an innovative hinge device that exhibits a good damper effect and an electronic device using the hinge device.

従来から、第一部材と第二部材とを枢着して互いに重合した閉塞状態から開放回動するように構成したヒンジ装置において、この第二部材に対して開放した第一部材が閉塞する際、急激な回動を防止しゆっくりとした閉塞を実現するダンパー機能を発揮するダンパー機能付きヒンジ装置(以下、従来例)が種々提案されている。   Conventionally, in a hinge device configured to pivot from a closed state in which a first member and a second member are pivotally attached and overlapped with each other, the first member opened with respect to the second member is closed. Various types of hinge devices with a damper function (hereinafter, conventional examples) that exhibit a damper function that prevents a sudden rotation and realizes a slow closing have been proposed.

この従来例は、図25に図示したように第一部材に連結される第一回動体57と共に回動する第一摩擦体53と、第二部材に連結される第二回動体58と共に回動する第二摩擦体54とを具備し、この第一摩擦体53と第二摩擦体54とは第一回動体57と第二回動体58との組み付けにより圧接状態に設けられており、第一部材と第二部材との回動に際して緩衝作用を生じるように構成されている。   In this conventional example, as shown in FIG. 25, the first friction body 53 that rotates together with the first rotation body 57 connected to the first member, and the second rotation body 58 that connects to the second member rotate. The first friction body 53 and the second friction body 54 are provided in a pressure contact state by assembling the first rotation body 57 and the second rotation body 58, A buffering action is generated when the member and the second member are rotated.

ところで、従来例は、第一摩擦体53及び第二摩擦体54を合成樹脂で形成しているが、この第一摩擦体53及び第二摩擦体54の製造に際して寸法にばらつきが生じてしまい(接触面に凹凸ができたり、厚さが薄かったり)、よって、得たい(設計上希望とおりの)緩衝作用が得られない場合が多い。これに対し、この第一摩擦体53と第二摩擦体54を高精度に製造することで寸法のばらつきを押さえることは不可能ではないが、それでも不十分であり、しかも、コスト高で量産性が悪いという問題点がある。   By the way, in the conventional example, the first friction body 53 and the second friction body 54 are made of synthetic resin. However, when the first friction body 53 and the second friction body 54 are manufactured, the dimensions vary. In many cases, the contact surface is uneven, or the thickness is thin. Therefore, the desired buffering effect (as desired in design) cannot be obtained. On the other hand, it is not impossible to suppress variation in dimensions by manufacturing the first friction body 53 and the second friction body 54 with high accuracy, but it is still insufficient, and the cost is high and the mass productivity is high. There is a problem that is bad.

好適と考える本発明の実施形態を、図面に基づいて簡単に説明する。   Embodiments of the present invention considered to be suitable will be briefly described with reference to the drawings.

第一部材1と第二部材2との回動に際して、第一部材1と共に回動する第一摩擦体3と、第二部材2と共に回動する第二摩擦体4との間で接触による緩衝作用を生じることになる。   When the first member 1 and the second member 2 are rotated, the first friction body 3 that rotates together with the first member 1 and the second friction body 4 that rotates together with the second member 2 are buffered by contact. This will produce an effect.

本発明は、第一摩擦体3と第二摩擦体4とを圧接付勢せしめる付勢体5を具備しており、第一摩擦体3と第二摩擦体4とは付勢体5に付勢されることで常に最適な接触での緩衝作用が簡易且つ確実に得られることになる。   The present invention includes a biasing body 5 that presses and biases the first friction body 3 and the second friction body 4, and the first friction body 3 and the second friction body 4 are attached to the biasing body 5. By being energized, a buffering action with an optimum contact can be obtained easily and reliably.

具体的には、前述した従来例のように部品の組み付けによって摩擦体同士を圧接させる構造の場合、摩擦体の寸法のばらつきにより得たい緩衝作用が得られない場合があるが(この寸法のばらつきを摩擦体を高精度に製造して対応しようとしても限界があり、コスト高で量産性が悪い。)、この点、本発明は、付勢体5を具備することで、この摩擦体に生じる寸法のばらつきを解消することができ、確実に得たい緩衝作用が得られることになり(安定的に高品位の製品が得られることになる)、しかも、簡易構造故にコスト安にして量産性に秀れることになる。   Specifically, in the case of a structure in which friction bodies are pressed against each other by assembling parts as in the above-described conventional example, the buffer action desired to be obtained may not be obtained due to variations in the dimensions of the friction bodies. If the friction body is manufactured with high precision, there is a limit, the cost is high, and the mass productivity is poor.) In this respect, the present invention is provided with the urging body 5 and is generated in the friction body. The dimensional variation can be eliminated, and the desired buffering effect can be obtained (a high-quality product can be stably obtained). Moreover, the simple structure makes the cost low and allows for mass productivity. It will excel.

また、請求項4,5,6,7記載の発明のように構成した場合には、ヒンジ装置の左右位置(複数箇所)にて良好な緩衝作用が発揮されることになり、しかも、左右の摩擦接触部10における圧接を達成する為の付勢を、この左右の摩擦接触部10の間に配される例えば一つの抗縮付勢体5の付勢力を利用して行なう効率の良い構造からヒンジ装置の小型化に確実に対応することができる。   Moreover, when comprised like invention of Claim 4,5,6,7, a favorable buffering effect will be exhibited in the left-right position (plural places) of the hinge device, From an efficient structure, the urging for achieving the pressure contact in the friction contact portion 10 is performed by using the urging force of one anti-contraction urging body 5 disposed between the left and right friction contact portions 10, for example. It is possible to reliably cope with downsizing of the hinge device.

また、請求項8記載の発明のように構成した場合には、筒状の回動軸9に対して例えばハーネスなどの配線を通すことができ、前述した請求項5,7記載の発明の構造に具備せしめることで回動軸の径大化にも確実に対応し得ることになる。   Moreover, when comprised like invention of Claim 8, wiring, such as a harness, can be passed with respect to the cylindrical rotation axis | shaft 9, for example, The structure of invention of Claim 5 and 7 mentioned above It is possible to reliably cope with an increase in the diameter of the rotating shaft.

具体的には、近年益々ヒンジ装置を用いる電子機器、例えば携帯電話やノート型パソコンなどに対する高機能化とコンパクト化が要求される中、ヒンジ装置にはより多くの配線(ハーネス)を通しつつ且つコンパクト化が要求されているが、つまり、例えばヒンジ装置の回動軸9に多くの配線を通す場合、回動軸9の径を大きくしなければならないが、その一方でヒンジ装置全体はコンパクト化しなければならず、よって、緩衝作用を発揮する摩擦体は小さくなってしまうが大きな荷重に対応し得る良好な緩衝作用を発揮しなければならない。   Specifically, in recent years, electronic devices using hinge devices, for example, mobile phones and notebook personal computers, are required to have high functionality and compactness. Although downsizing is required, that is, for example, when many wires are passed through the pivot shaft 9 of the hinge device, the diameter of the pivot shaft 9 must be increased. On the other hand, the entire hinge device is compacted. Therefore, the friction body that exhibits a buffering effect must be small, but must exhibit a good buffering effect that can handle a large load.

この点、請求項5,7記載の発明のように構成した場合には、ヒンジ装置の左右位置(複数箇所)に、左右の第一摩擦体3と該第一摩擦体3に隣接する第二摩擦体4とから成る摩擦接触部10を設けることで、より広い接触面積を得ることで良好な緩衝作用が発揮されることになるから、前述した回動軸9を筒状として配線を通す場合に最適な構造となる。   In this respect, when configured as in the fifth and seventh aspects of the invention, the left and right first friction bodies 3 and the second friction body 3 adjacent to the first friction bodies 3 are disposed at the left and right positions (a plurality of locations) of the hinge device. By providing the friction contact portion 10 composed of the friction body 4, a good buffering effect can be exhibited by obtaining a wider contact area. It becomes an optimal structure.

また、請求項10,11記載の発明のように構成した場合には、回動付勢機能を具備しつつ良好な緩衝作用が発揮されることになり、しかも、この回動付勢機能を発揮する回動付勢体13の空間S内に第一摩擦体3及び第二摩擦体4が配設されるという極めて効率の良い構造から良好な緩衝作用を具備しつつヒンジ装置の小型化に対応することができる。   Further, when configured as in the inventions according to claims 10 and 11, a satisfactory buffering effect is exhibited while having a rotation urging function, and this rotation urging function is exhibited. Since the first friction body 3 and the second friction body 4 are arranged in the space S of the rotating biasing body 13, the hinge device can be reduced in size while having a good buffering action. can do.

また、請求項12,13記載の発明のように、第一摩擦体3及び第二摩擦体4は互いに異なる素材、例えば第一摩擦体3,第二摩擦体4の一方は合成樹脂製、他方は金属製とした場合には、摩擦抵抗を向上し易いことになるからより良好な緩衝作用が得られることになる。   Further, as in the inventions of claims 12 and 13, the first friction body 3 and the second friction body 4 are made of different materials, for example, one of the first friction body 3 and the second friction body 4 is made of synthetic resin, and the other When made of metal, it is easy to improve the frictional resistance, so that a better buffering action can be obtained.

また、請求項14記載の発明のように、第一摩擦体3,第二摩擦体4の接触面3a,4aのうち少なくとも一方には凹状のグリス溜まり部6が設けられている場合には、圧接せしめられることで生じ得るグリス切れを可及的に防止することができ、グリスによる適度な潤滑を保ちながら常に良好な緩衝作用が得られることになる。   Further, as in the invention described in claim 14, when at least one of the contact surfaces 3a, 4a of the first friction body 3 and the second friction body 4 is provided with a concave grease reservoir portion 6, It is possible to prevent as much as possible the breakage of the grease that may occur due to the pressure contact, and a good buffering action is always obtained while maintaining appropriate lubrication with the grease.

また、請求項15記載の発明のように、グリス溜まり部6は接触面の回動中心を囲繞する状態で環状の凹条6aを設けて構成されている場合には、仮にグリス溜まり部6が接触面の回動方向と交差する方向(放射方向)に長さを有する凹条であった場合、この接触面の回動に際して抵抗となってしまう(支障を来たす)場合があるが、この点、前述した構成から、グリス溜まり部6を構成する凹条6aが接触面の回動に際して抵抗とならず、グリスによる適度な潤滑を保ちながら常に良好な緩衝作用が得られることになる。   Further, as in the invention described in claim 15, when the grease reservoir 6 is provided with the annular recess 6 a so as to surround the rotation center of the contact surface, the grease reservoir 6 is temporarily provided. If the groove has a length in the direction that intersects the direction of rotation of the contact surface (radial direction), it may become a resistance (disturbance) when the contact surface rotates. From the above-described configuration, the recess 6a constituting the grease reservoir 6 does not become a resistance when the contact surface rotates, and a good buffering action is always obtained while maintaining appropriate lubrication by the grease.

本発明の具体的な一実施例について図1〜6に基づいて説明する。   A specific embodiment of the present invention will be described with reference to FIGS.

本実施例は、第一部材1と第二部材2とを回動自在に連結するヒンジ装置であって、第一部材1と共に回動する第一摩擦体3と、この第一摩擦体3と接触して緩衝作用を生じながら第二部材2と共に回動する第二摩擦体4と、第一摩擦体3と第二摩擦体4とを圧接付勢せしめる付勢体5とを具備する所謂ダンパー機能を具備したヒンジ装置である。   A present Example is a hinge apparatus which connects the 1st member 1 and the 2nd member 2 rotatably, Comprising: The 1st friction body 3 rotated with the 1st member 1, This 1st friction body 3 and A so-called damper comprising a second friction body 4 that rotates together with the second member 2 while contacting and causing a buffering action, and a biasing body 5 that presses and biases the first friction body 3 and the second friction body 4. This is a hinge device having a function.

即ち、第一部材1と共に回動する第一回動体7に第一摩擦体3を設け、第一回動体7に回動軸9を介して相対回動自在に連結し第二部材2と共に回動する第二回動体8に第二摩擦体4を設け、第一摩擦体3,第二摩擦体4の少なくとも一方の摩擦体を、第一回動体7,第二回動体8の少なくとも一方の回動体、若しくは/及び、回動軸9にスライド自在に設けて、第一摩擦体3,第二摩擦体4を離反方向に相対移動自在に設けるとともに、第一摩擦体3と第二摩擦体4とを圧接付勢せしめる付勢体5を、第一回動体7,第二回動体8の少なくとも一方の回動体、若しくは/及び、回動軸9に設けて、第一回動体7と第二回動体8との相対回動に際して第一摩擦体3と第二摩擦体4との接触抵抗による緩衝作用が生じるように構成したものである。   That is, the first friction body 3 is provided on the first rotation body 7 that rotates together with the first member 1, and the first friction body 3 is connected to the first rotation body 7 via the rotation shaft 9 so as to be relatively rotatable. The second friction body 4 is provided on the moving second rotating body 8, and at least one of the first friction body 3 and the second friction body 4 is used as at least one of the first rotating body 7 and the second rotating body 8. The first friction body 3 and the second friction body are provided so as to be slidable on the rotation body or / and the rotation shaft 9 so that the first friction body 3 and the second friction body 4 are relatively movable in the separating direction. 4 is provided on at least one rotating body of the first rotating body 7 and the second rotating body 8, or / and the rotating shaft 9, so that the first rotating body 7 and the first rotating body 7 It is configured such that a buffering action is generated by contact resistance between the first friction body 3 and the second friction body 4 at the time of relative rotation with the two rotation bodies 8. .

具体的には、図1に示すように折り畳みタイプの携帯電話に適用した場合を示したもので、操作部21を備えた樹脂製の本体部1(筐体)を第一部材1とし、ディスプレイ部22を備えた樹脂製の開閉部2(筐体)を第二部材2とし、この本体部1に対して開閉部2が重合した閉塞状態から開閉部2を例えば120度まで回動した開放状態(通話状態)とすることができる枢着構造に本発明のヒンジ装置Hを適用している。   Specifically, as shown in FIG. 1, a case where the present invention is applied to a folding-type mobile phone is shown. A main body 1 (housing) made of resin having an operation unit 21 is used as a first member 1, and a display The resin opening / closing part 2 (housing) provided with the part 22 is used as the second member 2, and the opening / closing part 2 is opened by rotating the opening / closing part 2 up to 120 degrees, for example, from the closed state where the opening / closing part 2 overlaps the main body 1 The hinge device H of the present invention is applied to a pivot attachment structure that can be in a state (calling state).

また、本実施例では、本体部1の基部左右位置に連結凹部1aを設け、開閉部2の基部左右位置にも本体部1の連結凹部1aと連通状態に隣接する連結凹部2aを設け、この本体部1及び開閉部2の正面視右側連結部位における夫々の連結凹部1a,2aに軸状パーツとして構成した本発明のヒンジ装置Hを装着する構成としている。   Further, in this embodiment, the connection concave portion 1a is provided at the base left and right positions of the main body portion 1, and the connection concave portion 2a adjacent to the connection concave portion 1a of the main body portion 1 is also provided at the base left and right positions of the opening and closing portion 2. The hinge device H of the present invention configured as a shaft-like part is attached to each of the connecting recesses 1a and 2a in the right-side connection part of the main body 1 and the opening / closing part 2 when viewed from the front.

尚、本体部1及び開閉部2の正面視左側連結部位には、ボタンの押し操作により本体部1に対して開閉部2を所定回動角度位置に開放するまで回動付勢するプッシュオープン機能を発揮するヒンジ装置H’が設けられており、本実施例に係るヒンジ装置Hは、このヒンジ装置H’による付勢を伴う開放回動の際、緩衝作用(ダンパー効果)を発揮してゆっくりとした開放回動(高級感のある回動)を実現する。   Note that a push-open function that biases the main body unit 1 until the open / close unit 2 is opened to a predetermined rotation angle position by pressing a button is provided at a left side connection portion of the main body unit 1 and the open / close unit 2 when viewed from the front. The hinge device H ′ that exhibits the above is provided, and the hinge device H according to the present embodiment exhibits a buffering action (damper effect) slowly when the hinge device H ′ is opened and rotated by being biased by the hinge device H ′. Open rotation (high-quality rotation) is realized.

更に具体的には、図3,4に図示したように、開閉部2には、連結凹部2aに対して回り止め形状にした金属製のケース体(ケーシング)を第二回動体8としてこの開閉部2の連結凹部2aに嵌挿して回り止め状態に固定している。   More specifically, as shown in FIGS. 3 and 4, the opening / closing part 2 has a metal case body (casing) formed in a non-rotating shape with respect to the connection recess 2 a as a second rotating body 8. It is inserted into the connecting recess 2a of the part 2 and fixed in a non-rotating state.

この第二回動体8は、後述する金属製(ステンレス製)の第二摩擦体4を回り止め状態でスライド自在に収納し得る内面に凹条のガイド部8bを有する収納構造体であり、その一端部には中央に孔8a’を有する閉塞部8aが設けられており、この孔8a’は後述する第二摩擦体4の孔4bとともに回動軸9を軸受する軸受部として機能する。この回動軸9に対して第二摩擦体4は回動自在にして該回動軸9の長さ方向にスライド自在に設けられる。   The second rotating body 8 is a storage structure having a concave guide portion 8b on the inner surface capable of slidably storing a second friction body 4 made of metal (stainless steel), which will be described later, in a non-rotating state. One end portion is provided with a closing portion 8a having a hole 8a ′ at the center, and this hole 8a ′ functions as a bearing portion for bearing the rotating shaft 9 together with a hole 4b of the second friction body 4 described later. The second friction body 4 is provided so as to be rotatable with respect to the rotation shaft 9 so as to be slidable in the length direction of the rotation shaft 9.

また、第二回動体8の開口する他端位置にして該第二回動体8内に収納した第二摩擦体4の隣接位置には、合成樹脂製(シリコンゴム製)の第一摩擦体3が配されており、この第一摩擦体3は、第二回動体8に回動自在に連結する回動軸9の一端部に設けられ本体部1の連結凹部1aに回り止め状態に固定する第一回動体7(取付体7’)に設けられている。   In addition, the second friction body 4 accommodated in the second rotation body 8 at the other end position where the second rotation body 8 opens is adjacent to the first friction body 3 made of synthetic resin (made of silicon rubber). The first friction body 3 is provided at one end of a rotating shaft 9 that is rotatably connected to the second rotating body 8, and is fixed to the connecting recess 1a of the main body 1 in a non-rotating state. The first rotating body 7 (attachment body 7 ') is provided.

詳述すると、第二回動体8には、その回動軸9が貫通され、即ち、この回動軸9は第二回動体8の閉塞部8aに形成された孔8a’に嵌挿されると共に、第二摩擦体4がスライド移動自在にして回動自在に被嵌されるように第二摩擦体4の孔4aに嵌挿され、更に、この回動軸9の一端部に止着ピン11を介して合成樹脂製の第一回動体7が設けられ、この第一回動体7の内側には第二摩擦体4に隣接する第一摩擦体3が回り止め状態で設けられている。   More specifically, the second rotating body 8 is penetrated by the rotating shaft 9, that is, the rotating shaft 9 is inserted into a hole 8 a ′ formed in the closing portion 8 a of the second rotating body 8. The second friction body 4 is fitted in and inserted into the hole 4a of the second friction body 4 so that the second friction body 4 is slidably movably fitted. A first rotating body 7 made of synthetic resin is provided through the first rotating body 7, and the first friction body 3 adjacent to the second friction body 4 is provided inside the first rotating body 7 in a non-rotating state.

従って、第二回動体8内をスライド移動する第二摩擦体4は第一摩擦体3に対して離反方向に移動自在な状態となる(実際には付勢体5の付勢により第二摩擦体4が第一摩擦体3に対して離反方向に移動することはない。)。尚、第二摩擦体4における第一摩擦体3に対する離反方向への移動は、第二摩擦体4を第二回動体8に対してのみスライド自在、或いは、回動軸9に対してのみスライド自在となる構成としても良く、その他、第一摩擦体3も第二摩擦体4に対して離反方向に移動(第一回動体7、若しくは/及び、回動軸9に対してスライド移動)するように設けても良い。   Therefore, the second friction body 4 that slides in the second rotating body 8 is movable in the direction away from the first friction body 3 (actually, the second friction body 4 is urged by the urging force of the urging body 5). The body 4 does not move away from the first friction body 3). The second friction body 4 moves in the direction away from the first friction body 3 so that the second friction body 4 is slidable only with respect to the second rotating body 8 or only with respect to the rotating shaft 9. In addition, the first friction body 3 may also move in a direction away from the second friction body 4 (slide movement with respect to the first rotation body 7 and / or the rotation shaft 9). It may be provided as follows.

また、第一回動体7は、本体部1の基部に設けられた連結凹部1aに嵌合連結し得る断面多角形状部7aを有し、本体部1に対して回り止め状態に連結し得るように構成されている。   The first rotating body 7 has a polygonal section 7 a that can be fitted and connected to a connecting recess 1 a provided at the base of the main body 1, and can be connected to the main body 1 in a non-rotating state. It is configured.

また、第二回動体8内にして第二摩擦体4の外面と第二回動体4に係る閉塞部8aとの間には第二摩擦体4を所定方向に付勢するコイルバネを付勢体5(抗縮付勢体)として設けている。尚、付勢体5は一つに限らず複数設けても良く、コイルバネに限らず皿バネなどでも良い。   Further, a coil spring for biasing the second friction body 4 in a predetermined direction is provided between the outer surface of the second friction body 4 and the closing portion 8a of the second rotation body 4 in the second rotation body 8. 5 (anti-shrinkage biasing body) is provided. Note that the urging body 5 is not limited to one, and a plurality of urging bodies 5 may be provided.

この付勢体5は回動軸9に被嵌されており、第二摩擦体4を第一摩擦体3に対して圧接付勢せしめており、本実施例では第二摩擦体4と第一摩擦体3とから成る摩擦接触部10をヒンジ装置Hの一側一箇所に設けている。   The urging body 5 is fitted on the rotating shaft 9, and presses and urges the second friction body 4 against the first friction body 3. In this embodiment, the second friction body 4 and the first friction body 4 are urged. A friction contact portion 10 composed of the friction body 3 is provided at one side of the hinge device H.

従って、以上の構成からなるヒンジ装置Hは、第一回動体7と第二回動体8との相対回動に際して第一摩擦体3の内面としての接触面3aと第二摩擦体4の内面としての接触面4aとの接触抵抗による緩衝作用が生じるように構成されている。   Therefore, the hinge device H having the above configuration is used as the contact surface 3 a as the inner surface of the first friction body 3 and the inner surface of the second friction body 4 when the first rotation body 7 and the second rotation body 8 are relatively rotated. A buffering action is generated by contact resistance with the contact surface 4a.

また、本実施例では、第一摩擦体3及び第二摩擦体4は互いに異なる素材で構成されており、第一摩擦体3は合成樹脂製(硬度が約60度で厚みが約2.5mmのシリコンゴム製)の薄板状体、第二摩擦体4は金属製(ステンレス製)の薄板状体である。尚、第一摩擦体3を金属製とし、第二摩擦体4を合成樹脂製としても良い。   In the present embodiment, the first friction body 3 and the second friction body 4 are made of different materials, and the first friction body 3 is made of synthetic resin (the hardness is about 60 degrees and the thickness is about 2.5 mm). The second friction body 4 is a metal (stainless steel) thin plate-like body. The first friction body 3 may be made of metal, and the second friction body 4 may be made of synthetic resin.

また、第一摩擦体3,第二摩擦体4の接触面3a,4aのうち少なくとも一方には凹状のグリス溜まり部6が設けられており、本実施例では合成樹脂製である第一摩擦体3のみにグリス溜まり部6を設けている。   Further, a concave grease reservoir 6 is provided on at least one of the contact surfaces 3a, 4a of the first friction body 3 and the second friction body 4, and the first friction body made of synthetic resin in this embodiment. Only 3 is provided with a grease reservoir 6.

このグリス溜まり部6は、図5,6に図示したように接触面3aの回動中心を囲繞する状態で環状の凹条6aを設けて構成されている。   As shown in FIGS. 5 and 6, the grease reservoir 6 is configured by providing an annular recess 6 a so as to surround the rotation center of the contact surface 3 a.

従って、第一摩擦体3と第二摩擦体4とを付勢体5により圧接付勢せしめても接触面3a,4a同士間に塗布されたグリスが外部にはみだす所謂グリス切れの問題が生じなくなる。   Therefore, even if the first friction body 3 and the second friction body 4 are pressed and urged by the urging body 5, the so-called grease breakage problem that the grease applied between the contact surfaces 3a and 4a protrudes to the outside does not occur. .

本実施例は上述のように構成したから、前述した従来例のように部品の組み付けによって摩擦体同士を圧接させる構造の場合、摩擦体の寸法のばらつきにより得たい緩衝作用が得られない場合があるが(この寸法のばらつきを摩擦体を高精度に製造して対応しようとしても限界があり、コスト高で量産性が悪い。)、この点、本実施例は、付勢体5を具備することで、この摩擦体に生じる寸法のばらつきを解消することができ、確実に得たい緩衝作用が得られることに成り(安定的に高品位の製品が得られることになる)、しかも、簡易構造故にコスト安にして量産性に秀れることになる。   Since the present embodiment is configured as described above, in the case of the structure in which the friction bodies are pressed against each other by assembling the parts as in the above-described conventional example, the buffer action desired to be obtained may not be obtained due to variations in the dimensions of the friction bodies. Although there is a limit in trying to cope with this dimensional variation by manufacturing a friction body with high accuracy, this embodiment is provided with an urging body 5. This eliminates the dimensional variation that occurs in this frictional body, and the desired buffering effect can be obtained (a high-quality product can be stably obtained). Therefore, the cost will be reduced and the mass productivity will be excellent.

また、本実施例は、第一摩擦体3及び第二摩擦体4は互いに異なる素材、例えば第一摩擦体3,第二摩擦体4の一方は合成樹脂製、他方は金属製としたから、摩擦抵抗を向上し易いことになるからより良好な緩衝作用が得られることになる。   In the present embodiment, the first friction body 3 and the second friction body 4 are made of different materials, for example, one of the first friction body 3 and the second friction body 4 is made of synthetic resin, and the other is made of metal. Since the frictional resistance is easily improved, a better buffering action can be obtained.

また、本実施例は、第一摩擦体3,第二摩擦体4の接触面3a,4aのうち少なくとも一方には凹状のグリス溜まり部6が設けられているから、圧接せしめられることで生じ得るグリス切れを可及的に防止することができ、グリスによる適度な潤滑を保ちながら常に良好な緩衝作用が得られることになる。   Further, in this embodiment, since the concave grease reservoir 6 is provided on at least one of the contact surfaces 3 a and 4 a of the first friction body 3 and the second friction body 4, it can be caused by being pressed. It is possible to prevent the grease from being cut as much as possible and always obtain a good buffering action while maintaining appropriate lubrication by the grease.

また、本実施例は、グリス溜まり部6は接触面の回動中心を囲繞する状態で環状の凹条6aを設けて構成されているから、仮にグリス溜まり部6が接触面の回動方向と交差する方向(放射方向)に長さを有する凹条であった場合、この接触面の回動に際して抵抗となってしまう(支障を来たす)場合があるが、この点、前述した構成から、グリス溜まり部6を構成する凹条6aが接触面の回動に際して抵抗とならず、グリスによる適度な潤滑を保ちながら常に良好な緩衝作用が得られることになる。   Further, in this embodiment, the grease reservoir 6 is provided with an annular recess 6a so as to surround the rotation center of the contact surface, so that the grease reservoir 6 is assumed to be in the rotational direction of the contact surface. In the case of a concave strip having a length in the intersecting direction (radial direction), there may be a resistance (turning in trouble) when the contact surface is rotated. The recess 6a constituting the pool portion 6 does not become a resistance when the contact surface rotates, and a good buffering action is always obtained while maintaining appropriate lubrication with grease.

具体的には、図20に図示したように3つの第一摩擦体3の間に2つの第二摩擦体4を配するとともに、第一摩擦体3と第二摩擦体4同士の間に連結部材14Aを配した状態で重合連結する。この際、第二摩擦体4の表裏面に配される連結部材14A夫々の各孔14dからは第二摩擦体4の表裏面の各凸部4aが突出し、この突出する凸部4a(当接面4a)は連結部材14A介して隣接する第一摩擦体3の当接面3aに当接状態となる。   Specifically, as shown in FIG. 20, two second friction bodies 4 are arranged between the three first friction bodies 3 and connected between the first friction bodies 3 and the second friction bodies 4.

従って、第一回動体7と第二回動体8とを相対回動させた際、第一回動体7と共に回動する第一摩擦体3と第二回動体8と共に回動する第二摩擦体4との間に緩衝作用が生じる。   Accordingly, when the first rotating body 7 and the second rotating body 8 are relatively rotated, the first friction body 3 that rotates together with the first rotating body 7 and the second friction body that rotates together with the second rotating body 8. 4 has a buffering effect.

また、本実施例では、第一回動体7と第二回動体8との相対回動に際して緩衝作用を生じる前述したダンパー機能の他、第一回動体7と第二回動体8を回動付勢する回動付勢機能も具備する。   In this embodiment, in addition to the above-described damper function that produces a buffering action when the first rotating body 7 and the second rotating body 8 are rotated relative to each other, the first rotating body 7 and the second rotating body 8 are rotated.
