好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

例えば、腕9の橈骨遠位端の粉砕骨折を発症した際、該粉砕骨折によってバラバラに切離した骨4aに対し、一方向からピン3aを刺入する構成では、全ての切離した骨4aにピン3aを刺入することができない場合がある。   For example, when a crushed fracture of the distal end of the radius of the arm 9 develops, in the configuration in which the pins 3a are inserted from one direction with respect to the bone 4a separated by the crushed fracture, the pins are inserted into all the separated bones 4a. 3a may not be inserted.

この点、本発明は、切離した骨4aに放射状にピン3aを刺入できるから、様々な方向から切離した骨4aの夫々にピン3aを刺入し、更に、該ピン3aをピン支持部2aで支持することによって前記切離した骨4aの全てを固定することができ、よって、この切離した骨4aは良好に治癒することになる。   In this respect, according to the present invention, since the pins 3a can be inserted radially into the cut bone 4a, the pins 3a are inserted into the bones 4a cut from various directions, and the pins 3a are further connected to the pin support portion 2a. It is possible to fix all of the separated bones 4a by supporting the separated bones 4a. Therefore, the separated bones 4a are healed well.

本発明の具体的な実施例1について図1〜4に基づいて説明する。   A specific embodiment 1 of the present invention will be described with reference to FIGS.

本実施例は、両端部若しくはその近傍にピン支持部2a・2bが夫々設けられ骨4a・4bに添設される添設部材1と、前記ピン支持部2a・2bに支持され且つ骨4a・4bに刺入されるピン3a・3bとから成り、切離した骨4aを治癒させる創外固定器であって、一方のピン支持部2aは、複数のピン3aを支持し且つ前記切離した骨4aを囲繞する構成であり、該ピン支持部2aにより支持されるピン3aは、切離した骨4aに放射状に刺入可能に構成されているものである。   In this embodiment, pin support portions 2a and 2b are provided at both ends or in the vicinity thereof, an attachment member 1 attached to the bones 4a and 4b, and supported by the pin support portions 2a and 2b and the bones 4a and 2b. An external fixator comprising pins 3a and 3b inserted into 4b and healing the separated bone 4a. One pin support portion 2a supports a plurality of pins 3a and the separated bone 4a. The pin 3a supported by the pin support portion 2a is configured to be able to be inserted radially into the separated bone 4a.

添設部材1は、棒ネジ状の第一添設部材11と、該第一添設部材11と螺合される筒状の第二添設部材12とから構成されている。第一添設部材11に対して第二添設部材12を回動せしめることで、該第一添設部材11から該第二添設部材12が突没し、これにより添設部材1を伸縮することができる。   The attachment member 1 includes a rod-screw-like first attachment member 11 and a cylindrical second attachment member 12 that is screwed to the first attachment member 11. By rotating the second attachment member 12 with respect to the first attachment member 11, the second attachment member 12 protrudes and retracts from the first attachment member 11, and thereby the attachment member 1 is expanded and contracted. can do.

図中符号13は、第一添設部材11に対する第二添設部材12の不意の回動を阻止する為の止めネジである。   Reference numeral 13 in the figure denotes a set screw for preventing the second attachment member 12 from rotating unexpectedly with respect to the first attachment member 11.

前記ピン支持部2a・2bは、第一添設部材11及び第二添設部材12に夫々連設されている。   The pin support portions 2a and 2b are connected to the first attachment member 11 and the second attachment member 12, respectively.

第一添設部材11に連設されているピン支持部2a(以下、第一ピン支持部2aという。)は、添設部材1の延設方向と交叉する方向に延びる半環状ピン支持部が採用されている。   The pin support portion 2a (hereinafter referred to as the first pin support portion 2a) connected to the first attachment member 11 is a semi-annular pin support portion that extends in a direction crossing the extending direction of the attachment member 1. It has been adopted.

この半環状ピン支持部は、骨折部位を囲繞できるよう形状、例えば、腕9の橈骨遠位端(手首付近)の粉砕骨折を治療する為に添設部材1を腕9に添設した際、該半環状ピン支持部が手首付近を囲繞できる形状のものが採用されている。   This semi-annular pin support portion is shaped so as to surround the fracture site, for example, when the attachment member 1 is attached to the arm 9 in order to treat a crushed fracture of the distal end of the radius (near the wrist) of the arm 9 A shape in which the semi-annular pin support portion can surround the wrist is adopted.

尚、図面では、半環状ピン支持部としてく字状のものを図示したが、例えば、三日月状、Cリング状等、様々なものが採用可能である。   In the drawings, a semi-circular pin support portion is shown in a square shape, but various shapes such as a crescent shape and a C-ring shape can be employed.

第一ピン支持部2aとして、例えば、手首付近の全周囲を囲繞できる環状ピン支持部を採用しても良いが、この構成では、添設部材1を腕9に添設する際に手を環状ピン支持部に通さねばならず、この分だけ、添設作業が厄介となる。特に、膝等の骨折の際には、足を環状ピン支持部に通すことが大変厄介となる。   As the first pin support portion 2a, for example, an annular pin support portion that can surround the entire periphery in the vicinity of the wrist may be employed. However, in this configuration, when attaching the attachment member 1 to the arm 9, the hand is annular. It must be passed through the pin support part, and the attachment work becomes troublesome by this amount. In particular, in the case of a fracture such as a knee, it is very troublesome to pass the foot through the annular pin support.

半環状ピン支持部は二枚の半環状支持板5a・5bから成り、この二枚の半環状支持板5a・5b間に複数のピン3aを任意の間隔で挟持できるように構成されている。   The semi-annular pin support portion is composed of two semi-annular support plates 5a and 5b, and is configured such that a plurality of pins 3a can be sandwiched between the two semi-annular support plates 5a and 5b at an arbitrary interval.

この二枚の半環状支持板5a・5bは、調整ネジ6の操作によって間隔を広狭可能に構成されている。二枚の半環状支持板5a・5bの間隔を狭めれば、ピン3aの挟持が可能となり、また、該間隔を広げれば、ピン3aの挟持を解除することができる。   The two semi-annular support plates 5 a and 5 b are configured so that the interval can be widened by operating the adjusting screw 6. If the distance between the two semi-annular support plates 5a and 5b is narrowed, the pin 3a can be clamped, and if the gap is widened, the pin 3a can be released.

調整ネジ6は、半環状ピン支持部の両端部の近傍と中央部との合計三カ所に設けられている。各調整ネジ6を夫々調整することにより、二枚の半環状支持板5a・5bの間隔を場所ごとに微調整でき、よって、全てのピン3aを良好な挟持圧によって支持することができる。   The adjusting screws 6 are provided at a total of three locations, the vicinity of the both ends of the semi-annular pin support portion and the central portion. By adjusting each adjustment screw 6, the distance between the two semi-annular support plates 5 a and 5 b can be finely adjusted for each location, so that all the pins 3 a can be supported with good clamping pressure.

また、前記調整ネジ6が螺合するネジ孔27は、二枚の半環状支持板5a・5bの内の一方の半環状支持板5aにのみ設けられ、他方の半環状支持板5bには該調整ネジ6が貫通する貫通孔28のみが設けられている。この構成により、厄介な製造工程である前記ネジ孔27の穿設は、一方の半環状支持板5aに対してのみ行えば良いことになり、生産性が良好となる。   Further, the screw hole 27 into which the adjusting screw 6 is screwed is provided only in one of the two semi-annular support plates 5a and 5b, and the other semi-annular support plate 5b includes the screw hole 27. Only a through hole 28 through which the adjusting screw 6 passes is provided. With this configuration, it is only necessary to drill the screw hole 27, which is a troublesome manufacturing process, with respect to one of the semi-annular support plates 5a, thereby improving productivity.

また、二枚の半環状支持板5a・5bの対向内面には、摩擦部7(具体的には微細凹凸)が夫々設けられている。この摩擦部7の存在により、二枚の半環状支持板5a・5bはピン3aを極めて良好に支持することができる。   In addition, friction portions 7 (specifically, fine irregularities) are provided on opposing inner surfaces of the two semi-annular support plates 5a and 5b, respectively. Due to the presence of the friction part 7, the two semi-annular support plates 5a and 5b can support the pin 3a very well.

この第一ピン支持部2aと前記第一添設部材11とは、該第一添設部材11に対して該第一ピン支持部2aが屈曲及び旋回動できるように連設されている。   The first pin support portion 2a and the first attachment member 11 are connected to the first attachment member 11 so that the first pin support portion 2a can be bent and swiveled.

また、第一ピン支持部2aは第一添設部材11に着脱自在に連設されている。   The first pin support portion 2a is detachably connected to the first attachment member 11.

具体的には、第一添設部材11の端部には球部14が設けられ、この球部14が第一ピン支持部2aの中央部に当接し、該球部14は該第一ピン支持部2aと挟持板15とによって挟持されている。挟持板15は、中央部には前記第一添設部材11が挿通される挿通孔16と前記球部14に当接する当接部17とが設けられ、左右部にはネジ貫通孔18a・18bが夫々設けられている。第一ピン支持部2aにして前記ネジ貫通孔18a・18bと対応する位置にはネジ孔19a・19bが設けられている。   Specifically, a sphere portion 14 is provided at the end of the first attachment member 11, and this sphere portion 14 abuts on the central portion of the first pin support portion 2a, and the sphere portion 14 is in contact with the first pin. It is clamped by the support part 2a and the clamping plate 15. The clamping plate 15 is provided with an insertion hole 16 through which the first attachment member 11 is inserted and an abutting portion 17 that abuts against the ball portion 14 at the center, and screw through holes 18a and 18b at the left and right portions. Are provided. Screw holes 19a and 19b are provided at positions corresponding to the screw through holes 18a and 18b in the first pin support portion 2a.

第一添設部材11の球部14を第一ピン支持部2aと挟持板15とによって挟持せしめ、挟持板15側から、頭部20にネジ部21が設けられた構成の止着ネジ22を前記挟持板15のネジ貫通孔18a・18bに夫々貫通せしめ、該止着ネジ22のネジ部21を前記第一ピン支持部2aのネジ孔19a・19bに夫々螺合せしめると、止着ネジ22の頭部20が前記挟持板15を前記第一ピン支持部2a側に押圧し、これにより該挟持板15と該第一ピン支持部2aとが前記第一添設部材11の球部14を挟持する。   The ball portion 14 of the first attachment member 11 is clamped by the first pin support portion 2a and the clamping plate 15, and a fastening screw 22 having a structure in which the screw portion 21 is provided on the head 20 is provided from the clamping plate 15 side. When the screw through holes 18a and 18b of the clamping plate 15 are respectively inserted and the screw portions 21 of the fixing screws 22 are screwed into the screw holes 19a and 19b of the first pin support portion 2a, the fixing screws 22 are obtained. The head 20 presses the clamping plate 15 toward the first pin support portion 2a, so that the clamping plate 15 and the first pin support portion 2a cause the ball portion 14 of the first attachment member 11 to move.

本実施例の調整ネジ6,止めネジ13,止着ネジ22,調整ネジ30,止着ネジ42等、全てのネジは、同一の工具(例えば六角レンチ)によって螺動操作できるものが採用されている。   In this embodiment, all the screws such as the adjusting screw 6, set screw 13, fixing screw 22, adjusting screw 30, fixing screw 42, etc. that can be screwed by the same tool (for example, a hexagon wrench) are adopted. Yes.

本実施例は、特に手首付近、具体的には腕9の橈骨遠位端の粉砕骨折を発症した際の治療に使用するもので、以下、その使用方法を説明する。   The present embodiment is used for treatment especially when a fracture fracture occurs in the vicinity of the wrist, specifically, at the distal end of the radius of the arm 9, and the method of using the same will be described below.

先ず、骨折により多数の小片状に切離した骨4aの全てにピン3aを夫々刺入する。この際、一方向からピン3aを夫々刺入するだけでは全ての切離した骨4aに刺入することができず、該ピン3aを所定間隔を置いた放射状とすることで全ての切離した骨4aへの刺入が可能となる(図4参照)。   First, the pins 3a are inserted into all the bones 4a separated into a large number of small pieces by fracture. At this time, it is not possible to insert all the separated bones 4a only by inserting the pins 3a from one direction, and all the separated bones 4a are formed by making the pins 3a radially at predetermined intervals. Can be inserted (see FIG. 4).

また、切離した骨4aを良好に固定する為、該切離した骨4aの近傍の骨4b、具体的には橈骨の骨折していない部分にもピン3bを刺入する。   Further, in order to fix the separated bone 4a satisfactorily, the pin 3b is inserted into the bone 4b in the vicinity of the separated bone 4a, specifically, the unbroken portion of the rib.

続いて、添設部材1を腕9の近傍に位置せしめ、第一ピン支持部2aで前記切離した骨4aに刺入したピン3aを支持し、第二ピン支持部2bで前記橈骨に刺入したピン3bを支持する。   Subsequently, the attachment member 1 is positioned in the vicinity of the arm 9, the pin 3a inserted into the cut bone 4a is supported by the first pin support portion 2a, and the rib is inserted by the second pin support portion 2b. The pin 3b is supported.

この際、第一ピン支持部2aは、二枚の半環状支持板5a・5bから成る構成が採用されているから、前記所定間隔を置いて放射状となっている複数のピン3aの全てを良好に挟持して支持することができる。   At this time, since the first pin support portion 2a is composed of two semi-annular support plates 5a and 5b, all the plurality of pins 3a that are radially spaced at the predetermined interval are satisfactorily used. It can be supported by being held between.

また、当然ながら第二ピン支持部2bも、前記橈骨に刺入したピン3bの全てを良好に挟持して支持することができる。   Of course, the second pin support portion 2b can also hold and support all the pins 3b inserted into the ribs satisfactorily.

また、第一ピン支持部2aで支持するピン3aの並設方向と第二ピン支持部2bで支持するピン3bの並設方向とに合わせて、添設部材1に対して第一ピン支持部2aや第二ピン支持部2bを屈曲若しくは旋回動することにより、やはり全てのピン3a・3bを良好に挟持して支持することができる。   Further, the first pin support portion with respect to the attachment member 1 according to the parallel arrangement direction of the pins 3a supported by the first pin support portion 2a and the parallel arrangement direction of the pins 3b supported by the second pin support portion 2b. By bending or turning the 2a and the second pin support portion 2b, it is possible to hold and support all the pins 3a and 3b well.

また、第一添設部材11や第二添設部材12を回動させることによっても、第一ピン支持部2aや第二ピン支持部2bを骨4a・4bに刺入したピン3a・3bの位置に合わせることができ、よって、該ピン3a・3bを良好に挟持して支持することができる。   Further, by rotating the first attachment member 11 and the second attachment member 12, the pins 3a and 3b inserted into the bones 4a and 4b of the first pin support portion 2a and the second pin support portion 2b are also provided. Therefore, the pins 3a and 3b can be clamped and supported satisfactorily.

また、添設部材1の伸縮によっても、第一ピン支持部2aや第二ピン支持部2bを骨4a・4bに刺入したピン3a・3bの位置に合わせることができる。   The first pin support portion 2a and the second pin support portion 2b can be adjusted to the positions of the pins 3a and 3b inserted into the bones 4a and 4b by the expansion and contraction of the attachment member 1.

尚、本実施例は、橈骨遠位端の粉砕骨折を発症した際、該粉砕骨折によって切離した骨4aとその他の橈骨4bとにのみピン3a・3bを刺入する構成の為、骨折の治癒がある程度完了した後、該ピン3a・3bによって切離した骨4aを固定したまま、手首の屈伸や指を使用した仕事等のリハビリを行うことができる。即ち、骨折の治療を続けながら、リハビリを行うことができる。   In this embodiment, when the fracture of the distal end of the radius is developed, the pin 3a and 3b are inserted only into the bone 4a and other rib 4b separated by the fracture, so that the fracture is healed. Can be rehabilitated such as bending and stretching of the wrist and work using fingers while the bone 4a separated by the pins 3a and 3b is fixed. That is, rehabilitation can be performed while continuing the treatment of the fracture.

また、骨折の治癒がある程度完了した段階からリハビリを開始できる為、治癒を行う際に手首等を全く動かさない期間が短く、よって、手首や指の筋肉の衰えは少なく、リハビリ期間を短縮することができる。   In addition, since rehabilitation can be started from the stage where the healing of the fracture has been completed to some extent, the period when the wrist etc. are not moved at all during the healing is short. Can do.

骨折が完全に治癒した後、骨4a・4bからピン3a・3bを抜く。   After the fracture is completely healed, the pins 3a and 3b are removed from the bones 4a and 4b.

本実施例は上述のように構成したから、一方向からピン3aを刺入するだけでは全ての切離した骨4aに該ピン3aを刺入できないような骨折でも、放射状にピン3aを配設することで該全ての切離した骨4aにピン3aを刺入し、該ピン3aを一個の創外固定器で全て固定して治癒を良好に達成できる実用性に秀れた創外固定器となる。   Since the present embodiment is configured as described above, the pins 3a are arranged radially even in a fracture in which the pins 3a cannot be inserted into all the separated bones 4a only by inserting the pins 3a from one direction. Thus, the pin 3a is inserted into all the separated bones 4a, and all the pins 3a are fixed with one external fixator, thereby achieving an excellent external fixator excellent in practicality. .

また、第一ピン支持部2aは、放射状に配設されたピン3aを任意の間隔で支持できるから、切離した骨4aの状態に応じてピン3aを最適な状態に刺入し、且つ、該骨4aを固定して治癒を行うことができる。   In addition, since the first pin support portion 2a can support the radially arranged pins 3a at an arbitrary interval, the pin 3a is inserted into an optimum state according to the state of the bone 4a separated, and the Healing can be performed by fixing the bone 4a.

また、第一ピン支持部2aは添設部材1に対して屈曲したり旋回動したりできるから、この点においても切離した骨4aの状態に応じてピン3aを最適な状態に刺入し、且つ、該骨4aを固定して治癒を行うことができる。   In addition, since the first pin support portion 2a can be bent or swivel with respect to the attachment member 1, the pin 3a is inserted into an optimum state according to the state of the bone 4a separated also in this respect, In addition, the bone 4a can be fixed for healing.

また、第二ピン支持部2bも添設部材1に対して屈曲したり旋回動したりできるから、この点においても切離した骨4aの状態に応じてピン3bを最適な状態に刺入し、且つ、該骨4bや切離した骨4aを固定して治癒を行うことができる。   In addition, since the second pin support portion 2b can also be bent or swivel with respect to the attachment member 1, the pin 3b is inserted into an optimum state according to the state of the bone 4a separated also in this respect, In addition, the bone 4b and the separated bone 4a can be fixed and healed.

また、添設部材1は伸縮自在であるから、この点においても切離した骨4aや該切離した骨4aを固定する為の骨4bの状態に応じてピン3a・3bを最適な状態に刺入し、且つ、固定して治癒を行うことができる。   Further, since the attachment member 1 can be expanded and contracted, the pins 3a and 3b are inserted into an optimum state in accordance with the state of the separated bone 4a and the bone 4b for fixing the separated bone 4a. And it can be fixed and healed.

また、第一ピン支持部2aは半環状ピン支持部が採用されているから、手首等に被嵌する作業で該半環状ピン支持部を簡単に骨折部位の周囲に配設することができ、よって、ピン3a・3bの支持作業を容易に行うことができる。   Further, since the first pin support portion 2a employs a semi-annular pin support portion, the semi-annular pin support portion can be easily disposed around the fracture site in an operation of fitting on the wrist or the like. Therefore, it is possible to easily support the pins 3a and 3b.

尚、本実施例は、特に腕9の橈骨遠位端の粉砕骨折を治療する場合について説明したが、例えば、膝,肘等、他の骨折を治癒する場合にも採用することができる。   In addition, although the present Example demonstrated especially the case where the fracture | rupture fracture | rupture of the radius distal end of the arm 9 was treated, it can be employ | adopted also when healing other fractures, such as a knee and an elbow, for example.

本発明の具体的な実施例2について図5,6に基づいて説明する。   A second embodiment of the present invention will be described with reference to FIGS.

本実施例は、両端部若しくはその近傍にピン支持部80b・80cが、また、中程にはピン支持部80aが設けられ、ピン支持部80aとピン支持部80bの間及びピン支持部80aとピン支持部80cの間に夫々、骨4a・4b・4cに添設される添設部材1及び添設部材50が設けられ、前記ピン支持部80a・80b・80cには骨4a・4b・4cに刺入されるピン90a・90b・90cが設けられ、切離した骨4aを治癒させる創外固定器であって、中程のピン支持部80aは、複数のピン90aを支持し且つ前記切離した骨4aを囲繞する構成であり、該ピン支持部80aにより支持されるピン90aは、切離した骨4aに放射状に刺入可能に構成されているものである。   In this embodiment, pin support portions 80b and 80c are provided at both ends or in the vicinity thereof, and a pin support portion 80a is provided in the middle, and between the pin support portion 80a and the pin support portion 80b and between the pin support portion 80a and Between the pin support portions 80c, there are provided an attachment member 1 and an attachment member 50 attached to the bones 4a, 4b and 4c, respectively. The pin support portions 80a, 80b and 80c are provided with bones 4a, 4b and 4c. An external fixator provided with pins 90a, 90b, and 90c to be inserted into the bone to heal the separated bone 4a, and the intermediate pin support portion 80a supports the plurality of pins 90a and is separated. The pin 90a is configured to surround the bone 4a, and the pin 90a supported by the pin support portion 80a is configured to be able to be radially inserted into the separated bone 4a.

添設部材1は、棒ネジ状の第一添設部材81及び第三添設部材51と、該第一添設部材81及び第三添設部材51と螺合される筒状の第二添設部材82とから構成されている。第一添設部材81及び第三添設部材51に対して第二添設部材82を回動せしめることで、該第二添設部材82の両端部から該第一添設部材81及び第三添設部材51が突没し、これにより添設部材1を伸縮することができる。   The attachment member 1 includes a rod-like first attachment member 81 and a third attachment member 51, and a cylindrical second attachment member screwed to the first attachment member 81 and the third attachment member 51. And an installation member 82. By rotating the second attachment member 82 relative to the first attachment member 81 and the third attachment member 51, the first attachment member 81 and the third attachment member 82 are rotated from both ends of the second attachment member 82. The attachment member 51 protrudes and retracts, whereby the attachment member 1 can be expanded and contracted.

前記ピン支持部80a・80bは、第一添設部材81及び第三添設部材51に夫々連設されている。   The pin support portions 80a and 80b are connected to the first attachment member 81 and the third attachment member 51, respectively.

第一添設部材81に連設されているピン支持部80a(以下、第一ピン支持部80aという。)は、添設部材1の延設方向と交叉する方向に延びる半環状ピン支持部が採用されている。   The pin support portion 80a (hereinafter referred to as the first pin support portion 80a) connected to the first attachment member 81 is a semi-annular pin support portion that extends in a direction crossing the extending direction of the attachment member 1. It has been adopted.

この半環状ピン支持部は、骨折部位を囲繞できるよう形状、例えば、腕9の橈骨遠位端(手首付近)の粉砕骨折を治療する為に添設部材1を腕9に添設した際、該半環状ピン支持部が手首付近を囲繞できる形状のものが採用されている。   This semi-annular pin support portion is shaped so as to surround the fracture site, for example, when the attachment member 1 is attached to the arm 9 in order to treat a crushed fracture of the distal end of the radius (near the wrist) of the arm 9 A shape in which the semi-annular pin support portion can surround the wrist is adopted.

尚、図面では、半環状ピン支持部としてく字状のものを図示したが、例えば、三日月状、Cリング状等、様々なものが採用可能である。   In the drawings, a semi-circular pin support portion is shown in a square shape, but various shapes such as a crescent shape and a C-ring shape can be employed.

第一ピン支持部80aとして、例えば、手首付近の全周囲を囲繞できる環状ピン支持部を採用しても良いが、この構成では、添設部材1を腕9に添設する際に手を環状ピン支持部に通さねばならず、この分だけ、添設作業が厄介となる。特に、膝等の骨折の際には、足を環状ピン支持部に通すことが大変厄介となる。   As the first pin support portion 80a, for example, an annular pin support portion that can surround the entire periphery in the vicinity of the wrist may be employed. However, in this configuration, when attaching the attachment member 1 to the arm 9, the hand is annular. It must be passed through the pin support part, and the attachment work becomes troublesome by this amount. In particular, in the case of a fracture such as a knee, it is very troublesome to pass the foot through the annular pin support.

半環状ピン支持部は二枚の半環状支持板83a・83bから成り、この二枚の半環状支持板83a・83b間に複数のピン90aを任意の間隔で挟持できるように構成されている。   The semi-annular pin support portion includes two semi-annular support plates 83a and 83b, and is configured such that a plurality of pins 90a can be sandwiched between the two semi-annular support plates 83a and 83b at an arbitrary interval.

この二枚の半環状支持板83a・83bは、調整ネジ84の操作によって間隔を広狭可能に構成されている。二枚の半環状支持板83a・83bの間隔を狭めれば、ピン90aの挟持が可能となり、また、該間隔を広げれば、ピン90aの挟持を解除することができる。   The two semi-annular support plates 83a and 83b are configured such that the interval can be increased or decreased by operating the adjustment screw 84. If the distance between the two semi-annular support plates 83a and 83b is narrowed, the pin 90a can be pinched, and if the gap is widened, the pin 90a can be pinched.

調整ネジ84は、半環状ピン支持部の両端部の近傍の合計二カ所に設けられている。各調整ネジ84を夫々調整することにより、二枚の半環状支持板83a・83bの間隔を場所ごとに微調整でき、よって、全てのピン90aを良好な挟持圧によって支持することができる。   The adjustment screws 84 are provided at two places in the vicinity of both end portions of the semi-annular pin support portion. By adjusting each adjustment screw 84, the distance between the two semi-annular support plates 83a and 83b can be finely adjusted for each location, and therefore, all the pins 90a can be supported with good clamping pressure.

また、前記調整ネジ84が螺合するネジ孔85は、二枚の半環状支持板83a・83bの内の一方の半環状支持板83aにのみ設けられ、他方の半環状支持板83bには該調整ネジ84が貫通する貫通孔86のみが設けられている。この構成により、厄介な製造工程である前記ネジ孔85の穿設は、一方の半環状支持板83aに対してのみ行えば良いことになり、生産性が良好となる。   Further, the screw hole 85 into which the adjusting screw 84 is screwed is provided only in one of the two semi-annular support plates 83a and 83b, and the other semi-annular support plate 83b includes the screw hole 85. Only a through hole 86 through which the adjustment screw 84 passes is provided. With this configuration, it is only necessary to drill the screw hole 85, which is a troublesome manufacturing process, with respect to one of the semi-annular support plates 83a, thereby improving productivity.

また、二枚の半環状支持板83a・83bの対向内面には、摩擦部87(具体的には微細凹凸)が夫々設けられている。この摩擦部87の存在により、二枚の半環状支持板83a・83bはピン90aを極めて良好に支持することができる。   In addition, friction portions 87 (specifically, fine irregularities) are respectively provided on the opposing inner surfaces of the two semi-annular support plates 83a and 83b. Due to the presence of the friction portion 87, the two semi-annular support plates 83a and 83b can support the pin 90a very well.
