Engaging pins 50 and 52 are respectively arranged on the outside and inside intermediate plates 34 and 36 of the chains 8 and 10, and circular arc-shaped recessed parts 54 and 56 for sandwiching the engaging pins 50 and 52 are formed on both ends of the outside and inside intermediate plates 46 and 48 of the chain 10.

Description

本発明は、駆動輪に巻き掛けされた１対のチェーンを進退駆動させるチェーンの繰り出し装置に関する。   The present invention relates to a chain feeding device that drives a pair of chains wound around driving wheels to advance and retreat.

従来、上記のチェーンの繰り出し装置としては、例えば特許文献１に開示されているものがある。特許文献１の技術では、間隔をおいて１対の駆動輪を配置し、各駆動輪にそれぞれチェーンを９０度に屈曲するように巻き掛けてある。この巻き掛けは、１対のチェーンの上記間隔内にある部分が対向するように、上記の間隔の外部にある部分がそれぞれ反対方向にあるように、行われている。１対のチェーンの上記間隔内にある部分では、対向面にそれぞれ凸部が互いに噛み合うように設けられている。これら凸部が噛み合うことによって、１対のチェーンが自立する。   Conventionally, as the above-described chain feeding device, there is one disclosed in Patent Document 1, for example. In the technique of Patent Document 1, a pair of drive wheels are arranged at intervals, and a chain is wound around each drive wheel so as to bend at 90 degrees. This winding is performed so that the portions outside the interval are in opposite directions so that the portions within the interval of the pair of chains face each other. In the portion of the pair of chains that are within the interval, the convex portions are provided on the opposing surfaces so as to mesh with each other. A pair of chains is self-supporting by the engagement of these convex portions.

特開平８−１６９６９３号公報Japanese Patent Laid-Open No. 8-169693

特許文献１の技術によれば、対向する凸部同士を噛み合わせる構成であるので、対向する凸部同士が干渉して、噛み合いが不安定な状態になりやすく、円滑にチェーンの伸張、退縮を円滑に行い難かった。   According to the technique of Patent Document 1, since the opposing convex portions are engaged with each other, the opposing convex portions interfere with each other, and the engagement tends to be unstable, and the chain can be smoothly extended and retracted. It was difficult to do smoothly.

本発明は、１対のチェーンの伸張退縮を円滑に行うことができるチェーンの繰り出し装置を提供することを目的とする。   An object of the present invention is to provide a chain feeding device that can smoothly perform extension and retraction of a pair of chains.

本発明の一態様のチェーンの繰り出し装置は、第１及び第２の駆動輪を有している。第１及び第２の駆動輪は、所定の間隔をおいて配置され、互いに平行な回転軸の回りに回転可能である。第１の駆動輪に第１のチェーンの一部が前記間隔内において噛み合わされ、第２の駆動輪に第２のチェーンの一部が前記間隔内において噛み合わされている。第１のチェーンは、前記間隔内における第１の駆動輪と非噛み合い部分が前記回転軸に対して直角な方向に直線状に位置し、第１の駆動輪との噛み合い部分を経て前記間隔外で前記間隔内での方向とほぼ９０度曲がった方向に位置する。同様に、第２のチェーンは、前記間隔内における第１の駆動輪と非噛み合い部分が第１のチェーンと対向しかつ前記回転軸に対して直角な方向に直線状に位置し、第２の駆動輪との噛み合い部分を経て前記間隔外で前記間隔内での方向とほぼ９０度曲がり、かつ第１のチェーンの間隔外の部分の方向と反対方向に位置する。少なくとも第１のチェーンの各前記リンクには、それぞれ第１のチェーンの係合用のピンが各前記リンクに対して垂直に設けられている。少なくとも第２のチェーンの前記各リンクの隣接する前記リンクと連結されている連結端部の縁部には第２のチェーンの係合用凹部がそれぞれ形成されている。各前記連結端部の縁部は、前記間隔の外部では隣接する前記連結端部の縁部とほぼ接している。各前記連結端部の縁部は、前記間隔内での第２の駆動輪との噛み合い部分では隣接する前記連結端部の縁部と離れ再び近づく。各前記連結端部の縁部は、前記間隔内での第２の駆動輪との非噛み合い部分において隣接する前記連結端部の縁部と接触して、隣接する２つの連結端部の前記第２のチェーンの係合用凹部が第１のチェーンの係合用のピンを両側から挟持する。第１及び第２のチェーンは、同一ピッチのリンクを連結して構成することが望ましく、その場合、第１のチェーンと、第２のチェーンは、第１及び第２の駆動輪の間隔内において半ピッチずらして位置させることが望ましい。この場合、第１のチェーンの係合用リンクは、第１のチェーンのリンクの長さ方向のほぼ中央に設けることが望ましい。第２のチェーンの隣接する接触縁は、第１のチェーンの係合用ピンの第２のチェーンの係合用凹部での挟持を円滑に進めるために、湾曲させることが望ましい。   The chain feeding device according to one aspect of the present invention includes first and second drive wheels. The first and second drive wheels are arranged at a predetermined interval and are rotatable about rotation axes parallel to each other. A portion of the first chain is engaged with the first drive wheel within the interval, and a portion of the second chain is engaged with the second drive wheel within the interval. In the first chain, the first drive wheel and the non-engagement portion within the interval are linearly positioned in a direction perpendicular to the rotation axis, and the first chain is out of the interval via the engagement portion with the first drive wheel. Thus, it is located in a direction bent by approximately 90 degrees with respect to the direction within the interval. Similarly, the second chain has a first drive wheel and a non-engagement portion within the interval facing the first chain and linearly positioned in a direction perpendicular to the rotation axis, and the second chain Through the meshing portion with the drive wheel, it bends approximately 90 degrees outside the interval and in the direction within the interval, and is positioned in the direction opposite to the direction of the portion outside the interval of the first chain. At least each link of the first chain is provided with a pin for engaging the first chain perpendicular to the link. A recess for engaging the second chain is formed at least at the edge of the connecting end portion connected to the link adjacent to each link of the second chain. The edge of each of the connecting ends is substantially in contact with the edge of the adjacent connecting end outside the interval. The edge portion of each connecting end portion is separated from the edge portion of the adjacent connecting end portion and approaches again at the meshing portion with the second drive wheel within the interval. An edge portion of each of the connection end portions is in contact with an edge portion of the adjacent connection end portion in a non-engagement portion with the second drive wheel within the interval, and the second connection end portions of the adjacent connection end portions are in contact with each other. The engagement recesses of the second chain hold the engagement pins of the first chain from both sides. The first and second chains are preferably configured by connecting links of the same pitch, in which case the first chain and the second chain are within the distance between the first and second drive wheels. It is desirable to shift the position by half a pitch. In this case, it is desirable that the engagement link of the first chain is provided at substantially the center in the length direction of the link of the first chain. Adjacent contact edges of the second chain are preferably curved in order to facilitate the clamping of the engagement pins of the first chain in the engagement recesses of the second chain.

このように構成されたチェーンの繰り出し装置では、第１及び第２のチェーンが所定の間隔内において第１及び第２の駆動輪に噛み合い、その噛み合いから離れた状態で、第１のチェーンの係合用ピンは、第２のチェーンの第２の係合用凹部によって挟持されており、第１及び第２のチェーンは、安定的に噛み合い、さらに、係合用のピンと係合用凹部とで負荷を受けるので、第１及び第２のチェーンを構成しているローラ用のピンに掛かる負荷が軽減される。   In the chain feeding device configured as described above, the first and second chains engage with the first and second drive wheels within a predetermined interval, and the first chain is engaged with the first and second drive wheels away from the engagement. The combination pin is sandwiched between the second engagement recesses of the second chain, and the first and second chains are stably engaged with each other, and the load is received by the engagement pins and the engagement recesses. The load applied to the roller pins constituting the first and second chains is reduced.

さらに、第２のチェーンの前記各リンクにも、それぞれ第２のチェーンの係合用のピンが各前記リンクに対して垂直に設けることができる。この場合、第１のチェーンにも、第２の係合部用凹部と同様に第１のチェーンの係合用凹部が形成される。このように構成すると、第１及び第２のチェーンがより安定的に噛み合うし、第１及び第２のチェーンを構成してるローラ用のピンに掛かる負荷を更に軽減することができる。   Furthermore, each link of the second chain can be provided with a pin for engaging the second chain perpendicular to the link. In this case, the first chain engaging recess is formed in the first chain as well as the second engaging recess. If comprised in this way, the 1st and 2nd chain will mesh | engage more stably, and the load concerning the pin for rollers which comprises the 1st and 2nd chain can further be reduced.

以上のように、本発明によれば、２つのチェーンを安定的に噛み合わせて、円滑に伸縮させることができるし、チェーンを構成しているローラ用のピンに掛かる負荷を軽減することもできる。   As described above, according to the present invention, two chains can be stably meshed and smoothly expanded and contracted, and the load on the roller pins constituting the chain can be reduced. .

本発明の一実施形態のチェーンの繰り出し装置では、図３に示すように、中央に配置された駆動部２の両側にそれぞれ収納部４、６が配置されている。   In the chain feeding device according to the embodiment of the present invention, as shown in FIG. 3, storage portions 4 and 6 are respectively disposed on both sides of the drive portion 2 disposed in the center.

収納部４には、第１のチェーン、例えばチェーン８が収容され、収納部６には、第２のチェーン、例えばチェーン１０が収容されている。チェーン８、１０は、収納部４、６内では収納スペースを小さくするために、収納部４、６内に設けたガイド１２、１４に沿ってループ状態で収納され、先端部が、駆動部２内に引き出され、駆動部２内に設けた第１及び第２の駆動輪、例えば駆動輪１６、１８に一部が噛み合っている。   The storage unit 4 stores a first chain, for example, a chain 8, and the storage unit 6 stores a second chain, for example, a chain 10. The chains 8 and 10 are stored in a loop state along guides 12 and 14 provided in the storage units 4 and 6 in order to reduce the storage space in the storage units 4 and 6, and the leading end portion is the drive unit 2. The first and second drive wheels, for example, the drive wheels 16 and 18 provided inside the drive unit 2 are partially engaged with each other.

駆動輪１６は図４に示すように回転軸１７を有し、駆動輪１８も図示していないが回転軸を有している。駆動輪１６、１８は、それらの回転軸が平行になるように、図１に示すように所定の間隔をおいて配置され、駆動輪１６の回転軸１７は、図示していないモータに駆動軸１９を介して結合され、駆動輪１６はモータによって正逆転可能である。駆動輪１６の回転軸１７には駆動伝達輪２０が取り付けられ、この駆動伝達輪２０は、図１に示すように駆動輪１８の回転軸に結合されている駆動伝達輪２２と噛み合っている。従って、駆動輪１６、１８は、モータの回転に従って互いに反対方向に駆動され、駆動輪１６、１８に噛み合っているチェーン８、１０を同一方向に駆動する。   The driving wheel 16 has a rotating shaft 17 as shown in FIG. 4, and the driving wheel 18 also has a rotating shaft although not shown. The drive wheels 16 and 18 are arranged at a predetermined interval as shown in FIG. 1 so that their rotation axes are parallel to each other, and the rotation shaft 17 of the drive wheel 16 is connected to a motor (not shown). The drive wheel 16 can be rotated forward and backward by a motor. A drive transmission wheel 20 is attached to the rotation shaft 17 of the drive wheel 16, and this drive transmission wheel 20 meshes with a drive transmission wheel 22 coupled to the rotation shaft of the drive wheel 18 as shown in FIG. Accordingly, the drive wheels 16 and 18 are driven in opposite directions according to the rotation of the motor, and drive the chains 8 and 10 engaged with the drive wheels 16 and 18 in the same direction.

チェーン８、１０における駆動輪１６、１８に噛み合う前の部分は、ほぼ水平であって、チェーン８とチェーン１０とで、互いに反対方向に位置している。図２に拡大して示すように、チェーン８は、駆動輪１６に対して巻き付け角度が約９０度となるように、駆動輪１６、１８間の間隔の下部において噛み合っており、同様にチェーン１０も、駆動輪１８に対して巻き付け角度が約９０度となるように、駆動輪１６、１８間の間隔の下部において噛み合っている。従って、チェーン８、１０は、駆動輪１６、１８によって９０度に屈曲され、駆動輪１６、１８間の間隔において駆動輪１６、１８と非噛み合い状態にあるチェーン８、１０の部分（駆動輪１６、１８の上側半分に相当する部分）は、駆動輪１６、１８の回転軸に対して垂直な方向に伸びている。チェーン８、１０は、駆動輪１６、１８の回転に従って収納部４、６から繰り出され、駆動部２の上方に向かって上昇したり、下降したりする。   The portions of the chains 8 and 10 before meshing with the drive wheels 16 and 18 are substantially horizontal, and the chains 8 and 10 are positioned in opposite directions. As shown in an enlarged view in FIG. 2, the chain 8 meshes with the lower part of the space between the drive wheels 16 and 18 so that the winding angle with respect to the drive wheel 16 is about 90 degrees. In addition, they are meshed at the lower part of the space between the drive wheels 16 and 18 so that the wrapping angle with respect to the drive wheel 18 is about 90 degrees. Accordingly, the chains 8 and 10 are bent at 90 degrees by the drive wheels 16 and 18, and the portions of the chains 8 and 10 that are in non-engagement with the drive wheels 16 and 18 in the interval between the drive wheels 16 and 18 (drive wheels 16 , 18 (the portion corresponding to the upper half) extends in a direction perpendicular to the rotation axis of the drive wheels 16, 18. The chains 8 and 10 are drawn out from the storage portions 4 and 6 according to the rotation of the drive wheels 16 and 18, and ascend or descend toward the top of the drive portion 2.

チェーン８、１０の駆動部２の上方に突出している先端部は、チェーン先端連結部２４によって連結されている。このチェーン先端連結部２４に被駆動物が取り付けられる。例えば、このチェーン繰り出し装置を昇降装置として使用する場合、チェーン先端連結部２４に昇降台が取り付けられる。   The tip portions of the chains 8 and 10 that protrude above the drive portion 2 are connected by a chain tip connecting portion 24. A driven object is attached to the chain tip connecting portion 24. For example, when this chain feeding device is used as a lifting device, a lifting platform is attached to the chain tip connecting portion 24.

チェーン８は、図４に示すように、駆動輪１６の回転軸１７の長さ方向に間隔をおいて配置された２列に構成され、いずれの列も、１対の外側リンク板２６、２６と１対の内側リンク板２８、２８とを有し、外側リンク板２６の両端部に内側リンク板２８の両端部がピン３０によって結合されている。これらピン３０には、それぞれローラ３２が回転自在に取り付けられている。両列の間には、外側中間プレート３４、３４及び内側中間プレート３６、３６が、外側リンク板２６、２６、内側リンク板２８、２８それぞれに対応する位置に配置され、上記のピン３０によって外側リンク板２６、２６、内側リンク板２８、２８に結合されている。チェーン１０も同様に構成され、外側リンク板３８、３８、内側リンク板４０、４０、ピン４２、ローラ４４、外側中間プレート４６、４６及び内側中間プレート４８、４８を有している。   As shown in FIG. 4, the chain 8 is configured in two rows arranged at intervals in the length direction of the rotating shaft 17 of the drive wheel 16, and each row has a pair of outer link plates 26, 26. And a pair of inner link plates 28, 28, and both ends of the inner link plate 28 are coupled to both ends of the outer link plate 26 by pins 30. A roller 32 is rotatably attached to each pin 30. Between the two rows, the outer intermediate plates 34 and 34 and the inner intermediate plates 36 and 36 are disposed at positions corresponding to the outer link plates 26 and 26 and the inner link plates 28 and 28 respectively, The link plates 26 and 26 and the inner link plates 28 and 28 are coupled. The chain 10 is similarly configured and includes outer link plates 38 and 38, inner link plates 40 and 40, pins 42, rollers 44, outer intermediate plates 46 and 46, and inner intermediate plates 48 and 48.

外側中間プレート３４、３４、４６、４６と内側中間プレート３６、３６、４８、４８とは、同一の形状に形成され、図１に示すように、駆動輪１６、１８の間隔内にこれらから外れて外側リンク板２６、２６、３８、３８、内側リンク板２８、２８、４０、４０が位置する状態において、外側中間プレート３４、３４及び内側中間プレート３６、３６は、チェーン１０側を向くように、外側リンク板２６、２６、内側リンク板２８、２８から突出している概略直方体状である。同様に外側中間プレート４６、４６及び内側中間プレート４８、４８は、チェーン８側を向くように、外側リンク板３８、３８、内側リンク板４０、４０からから突出している概略直方体状である。駆動輪１６、１８の間隔内にこれらから外れて外側リンク板２６、２６、３８、３８、内側リンク板２８、２８、４０、４０が位置する状態において、外側中間プレート３４、３４及び内側中間プレート３６、３６の先端部は、外側中間プレート４６、４６及び内側中間プレート４８、４８の先端部と重なりあっており、しかも、外側中間プレート４６、４６、内側中間プレート４８、４８の両端が、外側中間プレート３４、３４、内側中間プレート３６、３６の長さ方向（外側リンク板２６、内側リンク板２８の長さ方向）のほぼ中央に位置し、外側中間プレート３４、３４、内側中間プレート３６、３６の両端が、外側中間プレート４６、４６、内側中間プレート４８、４８の長さ方向のほぼ中央に位置するように、チェーン８、１０は、半ピッチ（１ピッチはピン３０間の間隔及びピン４２間の間隔で同一の値である）ずらして駆動輪１６、１８に噛み合わされている。   The outer intermediate plates 34, 34, 46, 46 and the inner intermediate plates 36, 36, 48, 48 are formed in the same shape, and are separated from these within the interval of the drive wheels 16, 18 as shown in FIG. In the state where the outer link plates 26, 26, 38, 38 and the inner link plates 28, 28, 40, 40 are located, the outer intermediate plates 34, 34 and the inner intermediate plates 36, 36 face the chain 10 side. The outer link plates 26, 26 and the inner link plates 28, 28 have a substantially rectangular parallelepiped shape. Similarly, the outer intermediate plates 46 and 46 and the inner intermediate plates 48 and 48 have a substantially rectangular parallelepiped shape protruding from the outer link plates 38 and 38 and the inner link plates 40 and 40 so as to face the chain 8 side. In the state where the outer link plates 26, 26, 38, 38 and the inner link plates 28, 28, 40, 40 are located within the distance between the drive wheels 16, 18, the outer intermediate plates 34, 34 and the inner intermediate plate are located. The tip portions of 36 and 36 overlap the tip portions of the outer intermediate plates 46 and 46 and the inner intermediate plates 48 and 48, and both ends of the outer intermediate plates 46 and 46 and the inner intermediate plates 48 and 48 are outside. The intermediate plates 34, 34 and the inner intermediate plates 36, 36 are located at substantially the center in the length direction (the length direction of the outer link plate 26, the inner link plate 28), and the outer intermediate plates 34, 34, the inner intermediate plate 36, The chains 8, 10 are positioned so that both ends of 36 are located approximately in the center in the longitudinal direction of the outer intermediate plates 46, 46 and the inner intermediate plates 48, 48. Half pitch (1 pitch is the same value in the spacing between spacing and pin 42 between the pin 30) is shifted and in mesh to the drive wheels 16, 18.

外側中間プレート３４、３４における長さ方向の中央における幅方向（外側リンク板２６、内側リンク板２８の長さ方向に垂直な方向）において中央よりも幾分先端よりの位置間に、外側中間プレート３４、３４に跨って、即ち駆動輪１６の回転軸１７に平行に係合用ピン５０が取り付けられている。同様に、内側中間プレート３６、３６間に跨って係合用ピン５２が取り付けられている。   In the width direction (direction perpendicular to the length direction of the outer link plate 26 and the inner link plate 28) in the center in the length direction of the outer intermediate plates 34, 34, the outer intermediate plate is somewhat between the positions than the center. The engaging pin 50 is attached across the 34, 34, that is, parallel to the rotating shaft 17 of the drive wheel 16. Similarly, an engagement pin 52 is attached across the inner intermediate plates 36 and 36.

これら係合用ピン５０、５２を両側から挟持可能に、チェーン１０における外側中間プレート４６、４８の両側縁（外側リンク板３８、内側リンク板３８の長さ方向に対して垂直な方向の縁）の中央よりも幾分先端側に寄った位置に、係合用凹部、例えば円弧状凹部５４、５６が形成されている。これら円弧状凹部５４、５６は、チェーン８、１０が駆動輪１６、１８の間隔内において駆動輪１６、１８から外れた状態において、外側中間プレート４６、内側中間プレート４８の両側縁がほぼ接したときに、係合用ピン５０、５２をその両側（外側中間プレート４６、内側中間プレート４８の方向）から挟持するように形成されている。また、外側中間プレート４６、内側中間プレート４８の先端部の両端は、この挟持が円滑に行えるように湾曲させられている。   These engaging pins 50 and 52 can be clamped from both sides of the side intermediate edges 46 and 48 of the chain 10 (edges perpendicular to the length direction of the outer link plate 38 and the inner link plate 38). Engaging recesses, for example, arc-shaped recesses 54 and 56 are formed at positions somewhat closer to the tip side than the center. These arc-shaped concave portions 54 and 56 are substantially in contact with both side edges of the outer intermediate plate 46 and the inner intermediate plate 48 when the chains 8 and 10 are separated from the drive wheels 16 and 18 within the interval between the drive wheels 16 and 18. Sometimes, the engaging pins 50 and 52 are formed so as to be sandwiched from both sides thereof (in the direction of the outer intermediate plate 46 and the inner intermediate plate 48). Moreover, the both ends of the front-end | tip part of the outer side intermediate | middle plate 46 and the inner side intermediate | middle plate 48 are curved so that this clamping can be performed smoothly.

同様に、チェーン１０における外側中間プレート４６、内側中間プレート４８には係合用ピン５８、６０が形成され、チェーン８の外側中間プレート３４、内側中間プレート３６の両側縁には円弧状凹部６２、６４が形成されている。   Similarly, engaging pins 58 and 60 are formed on the outer intermediate plate 46 and the inner intermediate plate 48 of the chain 10, and arc-shaped recesses 62 and 64 are formed on both side edges of the outer intermediate plate 34 and the inner intermediate plate 36 of the chain 8. Is formed.

従って、チェーン８、１０がモータの回転によって駆動部２に向かって走行しているときには、チェーン８の外側中間プレート３４、３４、内側中間プレート３６、３８の両側縁はほぼ接しており、円弧状凹部６２、６４はほぼ接してほぼ円を成している。チェーン１０においても円孔状凹部５４、５６がほぼ円を成している。そして、チェーン８、１０が駆動輪１６、１８に噛み合い始めると、チェーン８の外側中間プレート３４、３４、内側中間プレート３６、３８の両側縁、チェーン１０の外側中間プレート４６、４６、内側中間プレート４８の円弧状凹部５４、５６は、それぞれ離れていき、駆動輪１６、１８の回転に従って徐々に近づき、再び接するときには、係合用ピン５０、５２を円弧状凹部５４、５６が挟持し、係合用ピン５８、６０を円弧状凹部６２、６４が挟持し、両チェーン８、１０を結合した状態となり、そのまま駆動部２の上方から繰り出される。この状態では、両チェーン８、１０が強固に連結されているので、両者が左右にがたつくこともない。モータを逆転させると、上記の説明と逆に動作して、チェーン８、１０は降下して、係合用ピン５０、５２の円弧状凹部５４、５６による挟持、係合用ピン５８、６０の円弧状凹部６２、６４による挟持がそれぞれ解除される。   Therefore, when the chains 8 and 10 are traveling toward the drive unit 2 by the rotation of the motor, both side edges of the outer intermediate plates 34 and 34 and the inner intermediate plates 36 and 38 of the chain 8 are substantially in contact with each other, and are arcuate. The recesses 62 and 64 are almost in contact with each other to form a circle. Also in the chain 10, the circular hole-shaped concave portions 54 and 56 are substantially circular. When the chains 8 and 10 start to engage with the drive wheels 16 and 18, both side edges of the outer intermediate plates 34 and 34 and the inner intermediate plates 36 and 38 of the chain 8, the outer intermediate plates 46 and 46 of the chain 10, and the inner intermediate plate 48 arcuate recesses 54 and 56 move away from each other and gradually approach as the drive wheels 16 and 18 rotate, and when contacting again, the arcuate recesses 54 and 56 hold the engagement pins 50 and 52 together. The pins 58 and 60 are clamped by the arc-shaped concave portions 62 and 64, and the two chains 8 and 10 are coupled together, and are fed out from the drive unit 2 as they are.

However, the present invention is not limited to this, and for example, one row or two or more rows can be used. In the above embodiment, the engaging pins 50, 52, 58, 60 and the arc-shaped concave portions 54, 56, 62, 64 are provided in the chains 8, 10, respectively. However, the engaging pins 50, 52 on the chain 8 side, the chain Only the arcuate recesses 54 and 56 on the 10 side may be provided, or conversely, only the engagement pins 58 and 60 on the chain 10 side and the circular recesses 62 and 64 on the chain 8 side may be provided. Further, in the above embodiment, the chains 8 and 10 use the outer and inner link plates 26 and 28 and the outer and inner intermediate plates 34 and 36. However, the present invention is not limited to this, for example, the outer and inner link plates. 26 and 28 may be removed, and the chains 8 and 10 may be constituted only by the outer and inner intermediate plates 34 and 36.
