【０００９】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１０】
本発明は、軸部３と軸受部４との相対回動に際して所定の接触抵抗が生じることになる。
【００１１】
この接触抵抗は、軸受部４に設けられ、軸部３に被嵌される複数のリング状部材５における当該軸部３に対する圧接により生じており、このリング状部材５の数を変えることで接触抵抗力は可変可能である。
【００１２】

また、例えばリング状部材５として一部が切欠されることで縮径し得るリング状部材５を採用し、このリング状部材５を軸受部４に設けた際、該リング状部材５が軸部３に対して圧接状態で被嵌し得るように軸受部４を構成した場合には、単にリング状部材５を軸受部４に設けるだけで良好な接触抵抗が得られることになる。
【００１４】
また、例えば軸部３に被嵌して軸受けする軸受部４にリング状部材５をスライドせしめるガイド部12を設けて、このガイド部12にスライドさせることで複数のリング状部材５を並設し得るように軸受部４を構成した場合には、このリング状部材５の軸受部４への並設が何ら複雑な構造ではなく、リング状部材５を順次軸受部４に設けることができる。
【００１５】
また、例えば軸受部４に複数のリング状部材５を並設した際、隣接するリング状部材５同志間にして前記軸部３に接触する内側部位にグリスだまりとなる凹部10が形成されるように構成した場合には、軸部３と軸受部４との相対回動に際して生じる接触抵抗力の調整が、リング状部材５の数を変えることで達成されることに加え、更に、グリスによっても調整できることになる。
【００１６】

【００２７】
このリング状部材５は、軸受部４に軸部３を嵌挿させた際、軸部３に対して圧接状態で被嵌し得るように構成されており、この軸部３に対するリング状部材５の圧接が軸部３と軸受部４との相対回動に際して所定の接触抵抗を生じせしめる。
【００２８】
また、軸受部４に複数のリング状部材５を並設した際、隣接するリング状部材５同志間にして前記軸部３に接触する内側部位にグリスだまりとなる凹部10が形成されるように構成されている（図８参照）。
【００２９】
また、リング状部材５は、予め軸受部４に並設状態に装着し、この状態で軸受部４に軸部３を嵌挿させることでリング状部材５を軸部３に被嵌させるようにしても良いし、或いは、予め軸部３に被嵌し、この状態で軸部３を軸受部４に嵌挿させるようにしても良い。
【００３０】
第二取付体８は、図３に図示したように適宜な金属製の部材で形成したものであり、ディスプレイ部２に係る取付孔に嵌合する断面方形状の取付部８ａに軸部３を突設状態に設けて構成されている。
【００３１】
この軸部３は、所定径を有する円柱状に形成して構成され、前述した軸受部４に回動自在に貫通状態に配され、その先端部にスナップリング９を止着することで第一取付体７に対して軸回動自在に抜け止め状態に連結されている。
【００３２】
また、軸部３は、軸受部４に連結した際、リング状部材５に被嵌されることになり、この軸３と軸受部４との相対回動に際してリング状部材５の内面との間に所定の接触抵抗が生じるように構成されている。この接触抵抗力は、リング状部材５の本数を変えることで可変可能である（図４，５参照）。
【００３３】
尚、軸部３，軸受部４及びリング状部材５は本実施例で述べた素材に限られるものではなく、本実施例の特性を発揮するものであれば適宜採用するものである。符号11はスペーサーである。
【００３４】
本実施例は上述のように構成したから、軸部３と軸受部４との相対回動に際して所定の接触抵抗が生じることになる。
【００３５】
この接触抵抗は、軸受部４に着脱自在に設けられ、軸部３に被嵌される複数のリング状部材５における当該軸部３に対する圧接により生じており、このリング状部材５の数を変えることで接触抵抗力は可変可能である。
【００３６】
よって、本実施例によれば、本体部１，ディスプレイ部２に設けられる軸部３，軸受部４の相対回動に際して所定の接触抵抗が生じるから、この接触抵抗力を、例えば本体部１に対してディスプレイ部２を所望の開放角度で保持するように構成したり、急激に閉じ回動するのを防止するように構成することができ、しかも、この接触抵抗力の調整がリング状部材５の本数を増減するだけで簡易且つ確実に行われることになり、そして、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。
【００３７】
また、本実施例は、リング状部材５として一部が切欠されることで縮径し得るリング状部材５を採用し、このリング状部材５を前記軸受部４に設けた際、該リング状部材５が前記軸部３に対して圧接状態で被嵌し得るように前記軸受部４を構成したから、単に軸受部４にリング状部材５をセットするだけで良好な接触抵抗が簡易且つ確実に得られることになる。

In addition to the fact that the adjustment of the contact resistance force that occurs when the shaft portion 3 and the bearing portion 4 are rotated relative to each other is achieved by changing the number of the ring-shaped members 5, it is also possible to use grease. You can adjust it.
[0016]
【Example】
Specific embodiments of the present invention will be described with reference to the drawings.
[0017]
This embodiment is applied to a notebook type personal computer as shown in the drawings, wherein the main body portion is the first member 1, the display portion is the second member 2, and the main body portion 1 and the display portion 2 are overlapped. The hinge device A of the present invention is applied to a pivoting structure in which the display unit 2 can be brought into an open state (use state) rotated, for example, by 120 degrees.

Each concave groove 12 is open at one end of the first attachment body 7, and is configured such that the ends 5 a and 5 b of the ring-shaped member 5 can be slid from the opening to be mounted in the bearing portion 4. ing.
[0024]
Therefore, the ring-shaped members 5 can be juxtaposed to the bearing portion 4 by sequentially sliding the plurality of ring-shaped members 5 from the one end side of the first attachment body 7 through the guide portion 12.
[0025]
As shown in FIG. 3, the ring-shaped member 5 is formed by forming an appropriate metal circular wire (piano wire) in a ring shape (C-shape), and a part thereof is notched. It has a suitable elasticity and can be reduced in diameter.
[0026]
Further, bent portions 5a and 5b which are bent outward are formed at both ends of the ring-shaped member 5 constituting the notch, and the bent portions 5a and 5b are engaged with the guide portion 12 associated with the bearing portion 4. By stopping, the ring-shaped member 5 can be attached to the bearing portion 4 in a locked state.
[0027]
The ring-shaped member 5 is configured to be fitted into the shaft portion 3 in a press-contact state when the shaft portion 3 is fitted into the bearing portion 4, and the ring-shaped member 5 with respect to the shaft portion 3. The pressure contact causes a predetermined contact resistance when the shaft portion 3 and the bearing portion 4 are rotated relative to each other.
[0028]
Further, when a plurality of ring-shaped members 5 are arranged side by side in the bearing portion 4, a recess 10 that becomes a pool of grease is formed in an inner portion that contacts the shaft portion 3 between adjacent ring-shaped members 5. It is configured (see FIG. 8).
