An insertion hole 61 through which the left end portion of the shaft 30 is inserted is formed in the central portion of the second cam member 60. The shape of the insertion hole 61 is formed in a non-circular oval shape having substantially the same shape as the cross-sectional shape of the left end portion of the shaft 30. Therefore, when the shaft 30 is inserted into the insertion hole 61, the shaft 30 and the second cam member 60 cannot rotate relatively.

第二カム部材６０の右側面には、第二カム面が形成されている。そして、第二カム面は、第一カム面と当接した状態とされる。
回動部材２０が固定部材１０に対して閉じた状態から開く方向に回動していくと、第一カム部材５０と第二カム部材６０とを合わせた厚みが厚くなるように、第一カム面と第二カム面と（第一カム面と第二カム面とが当接する部分）はそれぞれ傾斜する面で構成される。 A second cam surface is formed on the right side surface of the second cam member 60. Then, the second cam surface is in contact with the first cam surface.
When the rotating member 20 rotates in the opening direction from the closed state with respect to the fixing member 10, the first cam member 50 and the second cam member 60 together become thicker. The surface, the second cam surface, and (the portion where the first cam surface and the second cam surface come into contact with each other) are each composed of inclined surfaces.

第二カム部材６０の左側方（シャフト３０の先端部側）には、付勢部材である複数の皿バネ８０・８０・・がシャフト３０に挿通されて配設される。皿バネ８０・８０・・の右端部により第二カム部材６０は第一カム部材５０側に付勢される。
なお、本実施形態では、皿バネ８０・８０・・は四枚使用されているが、その枚数は限定されるものではない。 On the left side of the second cam member 60 (on the tip end side of the shaft 30), a plurality of disc springs 80, 80, which are urging members, are inserted through the shaft 30 and arranged. The second cam member 60 is urged toward the first cam member 50 by the right end of the disc springs 80, 80, and so on.
In this embodiment, four disc springs 80, 80, ... Are used, but the number of them is not limited.

シャフト３０の両端部には、ナットやワッシャ等が取付けられて、固定部材１０のシャフト孔１１または回動部材２０のシャフト孔２１からシャフト３０が脱落すること、また、第一カム部材５０、第二カム部材６０、及び皿バネ８０等がシャフト３０から脱落すること防止することを防止する。 Nuts, washers, and the like are attached to both ends of the shaft 30, so that the shaft 30 falls off from the shaft hole 11 of the fixing member 10 or the shaft hole 21 of the rotating member 20, and the first cam member 50, the first cam member 50, and the third. (2) It prevents the cam member 60, the disc spring 80, and the like from falling off from the shaft 30.

このように、回動部材２０が固定部材１０に対して開く方向に回動していくと、第一カム部材５０と第二カム部材６０とを合わせた厚みが次第に厚くなることから、皿バネ８０の付勢力に抗する力が大きくなる。このため、回動部材２０が固定部材１０に対して開く方向に回動していくとブレーキがかかるようにして、回動体（蓋９２）を本体９１から離間する方向（開く方向）に跳ね上げるように回動させた際の衝撃を緩和させることができる。 In this way, when the rotating member 20 rotates in the opening direction with respect to the fixing member 10, the combined thickness of the first cam member 50 and the second cam member 60 gradually increases, so that the disc spring The force against the urging force of 80 increases. Therefore, when the rotating member 20 rotates in the opening direction with respect to the fixing member 10, the brake is applied, and the rotating body (lid 92) is flipped up in the direction away from the main body 91 (opening direction). The impact when it is rotated in this way can be mitigated.

また以上のように、ヒンジ１では、固定部材１０と回動部材２０とシャフト３０とトーションバネ４０と第一カム部材５０と第二カム部材６０と当接部材７０と皿バネ８０とを備えることから、回動体（蓋９２）を本体９１から離間する方向（開く方向）に跳ね上げるように回動させた際の衝撃を緩和させることができるものを簡易な構成で実現することができる。 Further, as described above, the hinge 1 includes a fixing member 10, a rotating member 20, a shaft 30, a torsion spring 40, a first cam member 50, a second cam member 60, a contact member 70, and a disc spring 80. Therefore, it is possible to realize a simple configuration capable of alleviating the impact when the rotating body (lid 92) is rotated so as to be flipped up in a direction away from the main body 91 (opening direction).

また以上のように、トーションバネ４０と、当接部材７０と、を備え、トーションバネ４０の一端部４１が固定部材１０当接し、トーションバネ４０の他端部４２が当接部材７０に当接することによって、トーションバネ４０は回動部材２０を開く方向へ付勢するものであることから、回動体（蓋９２）を本体９１から離間する方向に跳ね上げるように回動させるものを、簡易な構成で実現することができ、部品毎の製品誤差によって動作不良が生じることを極力低減させることができる。 Further, as described above, the torsion spring 40 and the contact member 70 are provided, one end 41 of the torsion spring 40 comes into contact with the fixing member 10, and the other end 42 of the torsion spring 40 comes into contact with the contact member 70. As a result, since the torsion spring 40 urges the rotating member 20 in the opening direction, it is simple to rotate the rotating body (lid 92) so as to flip it up in the direction away from the main body 91. It can be realized by the configuration, and it is possible to reduce as much as possible the occurrence of malfunction due to product error for each part.

また以上のように、回動部材２０は、一対で構成されるものであり、左右にそれぞれ対向するように配置され、トーションバネ４０は、対向して配置される回動部材２０の間に配置され、シャフト３０は、トーションバネ４０に挿通され、当接部材７０は、回動部材２０間を渡るように配置されて、一対の回動部材２０・２０を連結するように構成されることから、回動体（蓋９２）を本体９１から離間する方向に跳ね上げるように回動させるものを簡易な構成で実現しつつコンパクトに構成することができる。 Further, as described above, the rotating members 20 are composed of a pair and are arranged so as to face each other on the left and right sides, and the torsion spring 40 is arranged between the rotating members 20 arranged so as to face each other. The shaft 30 is inserted through the torsion spring 40, and the contact member 70 is arranged so as to cross between the rotating members 20 so as to connect the pair of rotating members 20 and 20. , The rotating body (lid 92) can be rotated so as to be flipped up in a direction away from the main body 91, and can be compactly configured while realizing a simple configuration.

また以上のように、一対のトーションバネ４０の他端部４２は、ヒンジ１の左右端部にそれぞれ配位置され、トーションバネ４０の他端部４２は、トーションバネ４０の一端部４１よりもヒンジ１における回動軸方向中央側にそれぞれ配置され、当接部材７０の左右中央部近傍に当接することから、トーションバネ４０による回動部材２０を開く方向への付勢を安定させることができ、回動体（蓋９２）を本体９１から離間する方向に跳ね上げるように回動させる動作をより安定させることができる。 Further, as described above, the other end 42 of the pair of torsion springs 40 is arranged at the left and right ends of the hinge 1, and the other end 42 of the torsion spring 40 is more hinged than the one end 41 of the torsion spring 40. Since they are arranged on the center side in the rotation axis direction in No. 1 and abut on the vicinity of the left and right center portions of the abutting member 70, the torsion spring 40 can stabilize the urging of the rotating member 20 in the opening direction. The operation of rotating the rotating body (lid 92) so as to flip up in a direction away from the main body 91 can be made more stable.

回動部材２０は、当接部２４を備える。
回動部材２０の当接部２４は、回動部材２０が開く方向に回動していった際に固定部材１０に当接することによって回動部材２０の回動が規制されて、全開状態（回動部材２０の回動角度が８５°）とされる。回動部材２０の当接部２４は、回動部材２０の一端部の前端を外側に略直角に折り曲げることによって形成される。 The rotating member 20 includes a contact portion 24.
The contact portion 24 of the rotating member 20 is in a fully open state (the rotation of the rotating member 20 is restricted by abutting against the fixing member 10 when the rotating member 20 rotates in the opening direction. The rotation angle of the rotating member 20 is 85 °). The contact portion 24 of the rotating member 20 is formed by bending the front end of one end of the rotating member 20 outward at a substantially right angle.

固定部材１０は、切欠部１４を備える。
固定部材１０の切欠部１４は、固定部材１０の上下中途部の後面が凹状に切欠かれるように構成される。このように切欠部１４を備えることによって、回動部材２０が開く方向に回動していって全開状態となる前に固定部材１０に干渉することを防止することができる。 The fixing member 10 includes a notch 14.
The notch 14 of the fixing member 10 is configured such that the rear surface of the upper and lower halfway portion of the fixing member 10 is notched in a concave shape. By providing the notch portion 14 in this way, it is possible to prevent the rotating member 20 from rotating in the opening direction and interfering with the fixing member 10 before the fully opened state is reached.

ヒンジ１の組上げ方法について説明する。
まず、シャフト３０にトーションバネ４０を挿通して、当該シャフト３０の両端部に回動部材２０のシャフト孔２１に挿通し、次いでシャフト３０の両端部を固定部材１０のシャフト孔１１に挿通する。このとき、トーションバネ４０の一端部４１を固定部材１０の係止部１３に配置する。
次に、シャフト３０の左端部に、第一カム部材５０と第二カム部材６０とワッシャとを挿通し、シャフト３０の両端部をナット等で固定する。
このような状態で、当接部材７０を回動部材２０の連結孔２２に挿通してＥリングによって固定する。そして、当該当接部材７０にトーションバネ４０の他端部４２を引っ掛ける。
このようにしてヒンジ１は組上げられる。 A method of assembling the hinge 1 will be described.
First, the torsion spring 40 is inserted into the shaft 30, and both ends of the shaft 30 are inserted into the shaft holes 21 of the rotating member 20, and then both ends of the shaft 30 are inserted into the shaft holes 11 of the fixing member 10. At this time, one end 41 of the torsion spring 40 is arranged in the locking portion 13 of the fixing member 10.
Next, the first cam member 50, the second cam member 60, and the washer are inserted into the left end portion of the shaft 30, and both ends of the shaft 30 are fixed with nuts or the like.
In such a state, the contact member 70 is inserted into the connecting hole 22 of the rotating member 20 and fixed by the E ring. Then, the other end 42 of the torsion spring 40 is hooked on the contact member 70.
In this way, the hinge 1 is assembled.

以上のように、固定部材１０と、回動部材２０と、シャフト３０と、第一カム部材５０と、第二カム部材６０と、を組上げた後に、当接部材７０を回動部材２０に取付けて当該当接部材７０にトーションバネ４０の他端部４２を引っ掛けることによって、ヒンジ１が組上げられることから、トーションバネ４０を備える構成であってもヒンジ１の組上げ作業の煩雑さを低減させることができる。 As described above, after assembling the fixing member 10, the rotating member 20, the shaft 30, the first cam member 50, and the second cam member 60, the contact member 70 is attached to the rotating member 20. Since the hinge 1 is assembled by hooking the other end portion 42 of the torsion spring 40 on the contact member 70, the complexity of the assembling work of the hinge 1 can be reduced even in the configuration including the torsion spring 40. Can be done.

なお、トーションバネ４０は、一対で構成されることに限定されず、単数個または三個以上で構成することもできる。
トーションバネ４０が単数個で構成される場合、一対のトーションバネ４０・４０が近接する側の端部同士（他端部４２・４２同士）が連結するように構成され（図８参照）、トーションバネ４０の両端部がそれぞれ固定部材１０の係止部１３に係止され、トーションバネ４０の中央部において当接部材７０に当接するように構成することもできる。このように構成することによって、部品点数を削減することができ、またヒンジ１の組上げ作業の煩雑さをより低減させることができる。 The torsion spring 40 is not limited to being composed of a pair, and may be composed of a single number or three or more.
When the torsion spring 40 is composed of a single number, the ends of the pair of torsion springs 40 and 40 on the adjacent sides (the other ends 42 and 42) are connected to each other (see FIG. 8). Both ends of the spring 40 may be locked to the locking portions 13 of the fixing member 10, respectively, and may be configured to abut the abutting member 70 at the central portion of the torsion spring 40. With such a configuration, the number of parts can be reduced, and the complexity of the hinge 1 assembly work can be further reduced.
