It should be noted that the specific embodiments described herein are for the purpose of interpreting the present application only and are not intended to limit the present application.

本願の実施例は、カメラレンズの移動速度が遅く、画像形成の一致性が悪く、軸移動がスムーズに実施できないという従来技術の問題を解決するカメラレンズ調整機構、投影モジュール及び投影装置を提供する。 Embodiments of the present application provide a camera lens adjustment mechanism, a projection module, and a projection device that solve the problems of the prior art that the moving speed of the camera lens is slow, the consistency of image formation is poor, and the axis movement cannot be performed smoothly. .

第１態様では、本願の実施例はカメラレンズ調整機構を提供し、図１に示すように、カメラレンズ調整機構１０はカメラレンズ２０の位置を調整し、カメラレンズ２０の軸移動機能を達成させるものである。 In a first aspect, embodiments of the present application provide a camera lens adjustment mechanism, as shown in FIG. It is something.

また、図１に示すように、具体的には、カメラレンズ調整機構１０は、支持部材１１と、移動部材１２と、歯車１３とを含む。 Further, as shown in FIG. 1, specifically, the camera lens adjustment mechanism 10 includes a support member 11, a moving member 12, and a gear 13.

これらのうち、支持部材１１は移動部材１２を支持することができ、支持部材１１全体の形状は板状、柱状又は塊状などとしてもよいが、本願はこれについて特に制限しない。支持部材１１を製造する材料はアルミニウム、鉄や鋼などの金属材料であってもよいが、もちろん、ハードシリコンやプラスチックなどの材料であってもよく、本願はこれについても特に制限しない。 Among these, the support member 11 can support the moving member 12, and the overall shape of the support member 11 may be plate-like, column-like, block-like, etc., but the present application does not particularly limit this. The material for manufacturing the support member 11 may be a metal material such as aluminum, iron, or steel, but of course may also be a material such as hard silicon or plastic, and the present application does not particularly limit this.

移動部材１２は支持部材１１の側方に位置し、カメラレンズ２０は移動部材１２に取り付けられ、カメラレンズ２０は投影用カメラレンズや他のカメラレンズであってもよく、移動部材１２は第１所定方向ＡＡに摺動可能に支持部材１１に接続され、移動部材１２は第１所定方向ＡＡに延びているラック１２１を含み、ラック１２１は歯状構造を含む。移動部材１２はカメラレンズ２０を支持する部品であり、また、移動部材１２は支持部材１１に対して第１所定方向ＡＡに摺動可能であり、これによって、カメラレンズ２０を支持部材１１に対して第１所定方向ＡＡに摺動させてもよく、移動部材１２全体の形状は板状、柱状や塊状などとしてもよいが、本願はこれについて特に制限しない。移動部材１２を製造する材料はアルミニウム、鉄や鋼などの金属材料であってもよく、もちろん、移動部材１２を製造する材料はハードシリコン又はプラスチックなどの材料であってもよいが、本願はこれについても特に制限しない。 The movable member 12 is located on the side of the support member 11, the camera lens 20 is attached to the movable member 12, the camera lens 20 may be a projection camera lens or other camera lens, and the movable member 12 is located on the side of the support member 11. The movable member 12 is slidably connected to the support member 11 in a predetermined direction AA, and includes a rack 121 extending in a first predetermined direction AA, and the rack 121 includes a tooth-like structure. The movable member 12 is a component that supports the camera lens 20, and the movable member 12 is slidable relative to the support member 11 in the first predetermined direction AA, thereby moving the camera lens 20 relative to the support member 11. The moving member 12 may be slid in the first predetermined direction AA, and the entire shape of the moving member 12 may be plate-like, column-like, block-like, etc., but the present application does not particularly limit this. The material from which the moving member 12 is manufactured may be a metal material such as aluminum, iron, or steel.Of course, the material from which the moving member 12 is manufactured may be a material such as hard silicon or plastic; There are no particular restrictions on this either.

歯車１３は自体の軸方向を中心にして回転し、歯車１３の軸方向がカメラレンズ２０の光軸Ｏに平行であり、歯車１３の歯は歯状構造と噛み合う。 The gear 13 rotates around its own axial direction, the axial direction of the gear 13 is parallel to the optical axis O of the camera lens 20, and the teeth of the gear 13 mesh with the tooth-like structure.

なお、歯車１３は、自体の軸方向を中心にして回転するときに、ラック１２１を第１所定方向ＡＡに移動させ、移動部材１２を第１所定方向ＡＡに移動させ、カメラレンズ２０が移動部材１２に取り付けられるので、移動部材１２は第１所定方向ＡＡに移動するときに、カメラレンズ２０を第１所定方向ＡＡに移動させ、これにより、カメラレンズ２０の位置が調整され、カメラレンズ２０の軸移動機能が果たされ、歯車１３とネジ棒とによりカメラレンズ２０を移動駆動する場合よりも、歯車１３とラック１２１との方が、伝動速度が速く、伝動効率が高く、これにより、カメラレンズ２０の高速移動が可能になる。 Note that when the gear 13 rotates about its own axis, it moves the rack 121 in the first predetermined direction AA, moves the movable member 12 in the first predetermined direction AA, and the camera lens 20 moves in the first predetermined direction AA. 12, when the movable member 12 moves in the first predetermined direction AA, it moves the camera lens 20 in the first predetermined direction AA, thereby adjusting the position of the camera lens 20 and adjusting the position of the camera lens 20. The gear 13 and the rack 121 have a faster transmission speed and higher transmission efficiency than the case where the gear 13 and the threaded rod move the camera lens 20. High-speed movement of the lens 20 becomes possible.

さらに、図１及び図２に示すように、歯車１３の外周輪郭Ｋの所定断面Ｓが第１所定方向ＡＡに平行であり、所定断面Ｓは歯車１３のラック１２１に近い側に位置し、かつ、所定断面Ｓとカメラレンズ２０の光軸Ｏとが同一平面にあり、なお、図２においては、光軸Ｏは紙面方向に垂直である。 Furthermore, as shown in FIGS. 1 and 2, the predetermined cross section S of the outer peripheral contour K of the gear 13 is parallel to the first predetermined direction AA, the predetermined cross section S is located on the side of the gear 13 closer to the rack 121, and , the predetermined cross section S and the optical axis O of the camera lens 20 are on the same plane, and in FIG. 2, the optical axis O is perpendicular to the plane of the paper.

なお、歯車１３の外周輪郭Ｋにおいて第１所定方向ＡＡに平行である断面は２つあり、一方の断面は歯車１３のラック１２１に近い側に位置し、他方の断面は歯車１３のラック１２１から離れた側に位置し、歯車１３のラック１２１に近い側に位置する断面は所定断面Ｓである。 In addition, there are two cross sections in the outer peripheral contour K of the gear 13 that are parallel to the first predetermined direction AA, one cross section is located on the side closer to the rack 121 of the gear 13, and the other cross section is located from the rack 121 of the gear 13. A cross section located on the far side and closer to the rack 121 of the gear 13 is a predetermined cross section S.

またなお、歯車１３が回転するときに、ラック１２１に対する歯車１３の作用力は主に第１所定方向ＡＡに沿う駆動力であり、駆動力は主に歯車１３の外周輪郭Ｋのうち所定断面Ｓに相接する接点に集中し、即ち、駆動力は主に所定断面Ｓの所在する平面に集中し、このため、所定断面Ｓとカメラレンズ２０の光軸Ｏとが同一平面にある場合、ラック１２１に対する歯車１３の駆動力は主に光軸Ｏを通る所定断面Ｓに集中し、これにより、移動中のカメラレンズ２０の揺れを回避し、カメラレンズ２０の移動速度が遅く、画像形成の一致性が悪く、かつ、軸移動がスムーズに実施できないなどの関連技術の問題を解決する。 Furthermore, when the gear 13 rotates, the acting force of the gear 13 on the rack 121 is mainly a driving force along the first predetermined direction AA, and the driving force is mainly a predetermined cross section S of the outer peripheral contour K of the gear 13. In other words, the driving force is mainly concentrated on the plane where the predetermined cross section S is located. Therefore, when the predetermined cross section S and the optical axis O of the camera lens 20 are on the same plane, the rack The driving force of the gear 13 relative to the gear 121 is mainly concentrated on a predetermined cross section S passing through the optical axis O, thereby avoiding shaking of the camera lens 20 during movement, reducing the moving speed of the camera lens 20, and ensuring consistent image formation. To solve the problems of related technologies such as poor performance and inability to smoothly move the axis.

本願の一実施例では、前記第１所定方向ＡＡはカメラレンズ２０の光軸Ｏに垂直であってもよく、これにより、ラック１２１に対する歯車１３の駆動力は光軸Ｏを通る所定断面Ｓにより集中し、これにより、移動中のカメラレンズ２０の揺れをさらに防止する。 In one embodiment of the present application, the first predetermined direction AA may be perpendicular to the optical axis O of the camera lens 20, so that the driving force of the gear 13 with respect to the rack 121 is transmitted through the predetermined cross section S passing through the optical axis O. This further prevents shaking of the camera lens 20 during movement.

もちろん、第１所定方向ＡＡはカメラレンズ２０の光軸Ｏに対する垂直方向に対して一定の角度だけずれていてもよく、また、図１及び図２に示すように、本願の一実施例では、歯車１３は駆動部材１５がさらに設けられ、駆動部材１５は、支持部材１１に取り付けられ、歯車１３を自体の軸方向の周りに回転駆動させるものであり、電動機やモータなど、駆動力を有し、歯車１３を回転駆動し得るデバイスであってもよい。 Of course, the first predetermined direction AA may be shifted by a certain angle with respect to the direction perpendicular to the optical axis O of the camera lens 20, and as shown in FIGS. 1 and 2, in one embodiment of the present application, The gear 13 is further provided with a drive member 15, which is attached to the support member 11 and rotates the gear 13 around its own axis, and is powered by a motor, motor, etc. that has a driving force. , a device capable of rotationally driving the gear 13 may be used.

図３及び図４に示すように、本願のいくつかの実施例では、カメラレンズ調整機構１０は接続ユニット１４をさらに含み、接続ユニット１４は制限部材１４１を含み、制限部材１４１は、接続部１４１１と、接続部１４１１に接続される制限部１４１２とを含む。 As shown in FIGS. 3 and 4, in some embodiments of the present application, the camera lens adjustment mechanism 10 further includes a connection unit 14, the connection unit 14 includes a restriction member 141, and the restriction member 141 is connected to a connection portion 1411. and a restriction section 1412 connected to the connection section 1411.

これらのうち、制限部１４１２は支持部材１１の移動部材１２から離れた側に位置し、支持部材１１は接続部１４１１が第１所定方向ＡＡに摺動する摺動溝１１１を有し、接続部１４１１は摺動溝１１１を貫通して移動部材１２に接続され、制限部１４１２の第２所定方向ＢＢの最大長さがａ、摺動溝１１１の第２所定方向ＢＢの最大長さがｂであり、ａはｂよりも大きく、第２所定方向ＢＢは第１所定方向ＡＡ及び歯車１３の軸方向に垂直である。 Among these, the limiting part 1412 is located on the side of the supporting member 11 that is remote from the moving member 12, and the supporting member 11 has a sliding groove 111 in which the connecting part 1411 slides in the first predetermined direction AA. 1411 is connected to the moving member 12 through the sliding groove 111, and the maximum length of the limiting portion 1412 in the second predetermined direction BB is a, and the maximum length of the sliding groove 111 in the second predetermined direction BB is b. , a is larger than b, and the second predetermined direction BB is perpendicular to the first predetermined direction AA and the axial direction of the gear 13.

なお、接続ユニット１４は移動部材１２と支持部材１１とを接続して、カメラレンズ２０及び移動部材１２を支持部材１１に移動可能に取り付けるものであり、接続部１４１１は移動部材１２と制限部１４１２とを接続するものであり、摺動溝１１１は接続部１４１１が第１所定方向ＡＡに移動可能であり、これにより、接続部１４１１は移動部材１２に同期して移動可能であり、接続部１４１１が移動部材１２の第１所定方向ＡＡでの移動に影響を与えることを回避し、また、移動部材１２及び制限部１４１２はそれぞれ支持部材１１の両側に位置し、そして、第２所定方向ＢＢにおいて、制限部１４１２の最大長さａが摺動溝１１１の最大長さｂよりも大きく、これによって、移動部材１２と支持部材１１との分離を制限部１４１２で抑制することができる。 The connection unit 14 connects the movable member 12 and the support member 11 to movably attach the camera lens 20 and the movable member 12 to the support member 11, and the connection portion 1411 connects the movable member 12 and the restriction portion 1412. The sliding groove 111 allows the connecting portion 1411 to move in the first predetermined direction AA, so that the connecting portion 1411 can move in synchronization with the moving member 12, and the connecting portion 1411 The movement of the moving member 12 in the first predetermined direction AA is avoided, and the moving member 12 and the restriction portion 1412 are respectively located on both sides of the support member 11, and , the maximum length a of the restricting portion 1412 is greater than the maximum length b of the sliding groove 111, so that the restricting portion 1412 can suppress separation of the moving member 12 and the support member 11.

またなお、接続部１４１１と制限部１４１２とは一体形成されてもよいが、もちろん、接続部１４１１と制限部１４１２とは個別に成形された後、溶接、粘着、ネジ接続、係合やリベット留めなどの方式で接続されてもよい。 Furthermore, the connecting portion 1411 and the restricting portion 1412 may be formed integrally, but of course, the connecting portion 1411 and the restricting portion 1412 may be formed separately and then welded, adhesive, screwed, engaged, or riveted. The connection may be made in the following manner.

また、図３及び図４に示すように、本願の一実施例では、接続部１４１１は歯車１３の軸方向に延びており、接続ユニット１４は弾性部材１４２をさらに含み、弾性部材１４２は接続部１４１１を囲んで設けられ、制限部１４１２と支持部材１１との間に位置する。弾性部材１４２はバネであってもよいが、もちろん、弾性部材１４２はシリコーン、ラテックスや伸縮性スポンジなどのデバイスであってもよい。 Further, as shown in FIGS. 3 and 4, in one embodiment of the present application, the connecting portion 1411 extends in the axial direction of the gear 13, the connecting unit 14 further includes an elastic member 142, and the elastic member 142 1411 , and is located between the limiting portion 1412 and the support member 11 . The elastic member 142 may be a spring, but of course the elastic member 142 may also be a device such as silicone, latex, or stretchable sponge.

理解できるものとして、移動部材１２は、第１所定方向ＡＡに摺動するときに、支持部材１１と摩擦し、かつ、移動部材１２と支持部材１１とが密着すればするほど、移動部材１２が第１所定方向ＡＡに摺動するときに受ける摩擦力が大きくなり、弾性部材１４２の付勢力によって移動部材１２と支持部材１１との密着度が調整され、これにより、移動部材１２が第１所定方向ＡＡに摺動するときに受ける摩擦力が調整され、一般には、弾性部材１４２の圧縮の度合いが大きいほど、弾性部材１４２の制限部１４１２への反作用力が大きく、移動部材１２と支持部材１１がより密着する。 As can be understood, when the movable member 12 slides in the first predetermined direction AA, the movable member 12 rubs against the support member 11, and the closer the movable member 12 and the support member 11 come into contact, the more the movable member 12 moves. The frictional force received when sliding in the first predetermined direction AA increases, and the degree of close contact between the movable member 12 and the support member 11 is adjusted by the biasing force of the elastic member 142, thereby causing the movable member 12 to move in the first predetermined direction. The frictional force received when sliding in the direction AA is adjusted, and in general, the greater the degree of compression of the elastic member 142, the greater the reaction force of the elastic member 142 on the restricting portion 1412, and the greater the degree of compression of the elastic member 142. are in closer contact.

さらに、また図３及び図４に示すように、接続ユニット１４は、接続部１４１１を囲んで設けられ、制限部１４１２との間に弾性部材１４２が位置し、弾性部材１４２から離れた側面が支持部材１１に当接されるガスケット１４３をさらに含んでもよい。ガスケット１４３は弾性部材１４２を支持し、弾性部材１４２が摺動溝１１１に嵌入することを防止し、また、移動部材１２及びカメラレンズ２０が第１所定方向ＡＡに移動するときにバランスを維持する役割を果たし、カメラレンズ２０の傾斜を防止し、しかも、移動部材１２及びカメラレンズ２０の第１所定方向ＡＡの移動における弾性部材１４２と支持部材１１との間の摩擦力を減少させることができる。 Furthermore, as shown in FIGS. 3 and 4, the connection unit 14 is provided surrounding the connection part 1411, and the elastic member 142 is located between the connection part 1412 and the restriction part 1412, and the side surface remote from the elastic member 142 is supported. It may further include a gasket 143 that abuts the member 11. Gasket 143 supports elastic member 142, prevents elastic member 142 from fitting into sliding groove 111, and maintains balance when moving member 12 and camera lens 20 move in the first predetermined direction AA. In addition, it is possible to prevent the camera lens 20 from tilting and to reduce the frictional force between the elastic member 142 and the support member 11 when the moving member 12 and the camera lens 20 are moved in the first predetermined direction AA. .

ここでは、ガスケット１４３は、ガスケット１４３が第１所定方向ＡＡに移動するときにガスケット１４３と支持部材１１との摩擦を減少させるために、滑らかな金属ガスケット１４３であってもよい。 Here, the gasket 143 may be a smooth metal gasket 143 to reduce friction between the gasket 143 and the support member 11 when the gasket 143 moves in the first predetermined direction AA.

また、図３及び図４に示すように、本願の一実施例では、支持部材１１の制限部１４１２に近い側に制限溝１１２が設けられ、制限溝１１２は第１所定方向ＡＡに延びており、ガスケット１４３は制限溝１１２内に位置し、制限溝１１２に沿って摺動可能であり、摺動溝１１１は制限溝１１２の底壁に位置し、制限溝１１２はガスケット１４３を収納してガスケット１４３を保護することができ、また、制限溝１１２はガスケット１４３の移動方向を制限し、さらに移動部材１２及びカメラレンズ２０の移動方向を制限する。 Further, as shown in FIGS. 3 and 4, in one embodiment of the present application, a restriction groove 112 is provided on the side of the support member 11 near the restriction part 1412, and the restriction groove 112 extends in the first predetermined direction AA. , the gasket 143 is located within the restriction groove 112 and is slidable along the restriction groove 112, the sliding groove 111 is located on the bottom wall of the restriction groove 112, and the restriction groove 112 accommodates the gasket 143 and is able to slide along the restriction groove 112. 143, and the restriction groove 112 restricts the moving direction of the gasket 143, and further restricts the moving direction of the moving member 12 and the camera lens 20.

図５及び図６に示すように、接続ユニット１４は、移動部材１２に固定される摺動部材１４４であって、支持部材１１に摺動部材１４４が第１所定方向ＡＡに摺動する制限案内溝１１３が設けられ、制限案内溝１１３が第１所定方向ＡＡに延びている摺動部材１４４をさらに含んでもよい。 As shown in FIGS. 5 and 6, the connection unit 14 is a sliding member 144 fixed to the movable member 12, and the sliding member 144 is a limited guide for sliding in the first predetermined direction AA on the supporting member 11. The slide member 144 may further include a sliding member 144 provided with a groove 113 and with the restriction guide groove 113 extending in the first predetermined direction AA.

理解できるものとして、摺動部材１４４と制限案内溝１１３とを組み合わせることによって、移動部材１２と支持部材１１とが摺動可能に接続され、移動部材１２の移動中の自由度が制限され、移動部材１２が第１所定方向ＡＡに摺動するようにする。 As can be seen, the combination of the sliding member 144 and the restricting guide groove 113 slidably connects the moving member 12 and the support member 11, restricting the degree of freedom of the moving member 12 during movement, and restricting the movement of the moving member 12. The member 12 is caused to slide in the first predetermined direction AA.

また、図５及び図６に示すように、本願の一実施例では、摺動溝１１１は制限案内溝１１３の底壁に位置し、接続部１４１１の一端は摺動部材１４４に挿着され、これにより、接続部１４１１と摺動部材１４４とが接続されることで、移動部材１２と制限部１４１２との接続が実現され、しかも、接続部１４１１は摺動部材１４４に同期して第１所定方向ＡＡに移動する。 Further, as shown in FIGS. 5 and 6, in one embodiment of the present application, the sliding groove 111 is located on the bottom wall of the restriction guide groove 113, and one end of the connecting portion 1411 is inserted into the sliding member 144, As a result, the connecting portion 1411 and the sliding member 144 are connected, thereby realizing the connection between the movable member 12 and the limiting portion 1412, and the connecting portion 1411 is connected to the first predetermined position in synchronization with the sliding member 144. Move in direction AA.

ここで、接続部１４１１は摺動部材１４４に取り外し可能に接続されてもよく、接続部１４１１と摺動部材１４４とが接続されることにより、移動部材１２を支持部材１１に取り付けることができ、一方、接続部１４１１と摺動部材１４４とが分離することにより、移動部材１２を支持部材１１から取り外すことができ、このように接続部１４１１と摺動部材１４４とが取り外し可能に接続されることによって、支持部材１１への移動部材１２の着脱が容易になる。接続部１４１１は摺動部材１４４にネジ接続されてもよいが、もちろん、接続部１４１１はスプライン接続や係合接続など、取り外し可能な接続方式で摺動部材１４４に接続されてもよい。 Here, the connecting part 1411 may be removably connected to the sliding member 144, and by connecting the connecting part 1411 and the sliding member 144, the moving member 12 can be attached to the supporting member 11, On the other hand, by separating the connecting portion 1411 and the sliding member 144, the moving member 12 can be removed from the supporting member 11, and in this way, the connecting portion 1411 and the sliding member 144 are removably connected. This makes it easy to attach and detach the moving member 12 to and from the support member 11. The connecting portion 1411 may be threadedly connected to the sliding member 144, but of course, the connecting portion 1411 may also be connected to the sliding member 144 in a removable connection manner, such as a spline connection or an engagement connection.

また、図５及び図６に示すように、接続ユニット１４は、摺動部材１４４に囲んで接するように設けられ、制限案内溝１１３に沿って摺動可能な保護部材１４５をさらに含む。保護部材１４５は耐摩耗部品であり、摺動部材１４４を保護することができ、摺動部材１４４が制限案内溝１１３の内壁に直接接触することで摩擦により摩損されることを回避しつつ、移動中の摺動部材１４４と制限案内溝１１３の内壁との間の摩擦力を減少させ、しかも、保護部材１４５が摺動部材１４４を囲んで接するように設けられているので、保護部材１４５が摩損された場合保護部材１４５を交換することが容易である。 Further, as shown in FIGS. 5 and 6 , the connection unit 14 further includes a protection member 145 that is provided so as to surround and contact the sliding member 144 and is slidable along the restriction guide groove 113 . The protection member 145 is a wear-resistant component and can protect the sliding member 144, preventing the sliding member 144 from being worn out due to friction due to direct contact with the inner wall of the restriction guide groove 113, and preventing movement. The frictional force between the sliding member 144 inside and the inner wall of the restriction guide groove 113 is reduced, and since the protective member 145 is provided so as to surround and contact the sliding member 144, the protective member 145 is prevented from wear and tear. In this case, it is easy to replace the protection member 145.

ここで、保護部材１４５は高マンガン鋼、炭化ケイ素、窒化ケイ素、強靭化ジルコニア、又は強靭化亜酸化アルミニウムなどの耐摩耗性材で製造されてもよい。 Here, the protection member 145 may be made of a wear-resistant material such as high manganese steel, silicon carbide, silicon nitride, toughened zirconia, or toughened aluminum suboxide.

なお、図６は摺動部材１４４及び保護部材１４５の両方が円筒状である場合を例示したものに過ぎず、実際のニーズに応じては、摺動部材１４４及び保護部材１４５は板状や塊状などの形状としてもよく、本願はこれについて特に制限しない。 Note that FIG. 6 merely illustrates the case where both the sliding member 144 and the protective member 145 are cylindrical, and depending on actual needs, the sliding member 144 and the protective member 145 may be plate-shaped or block-shaped. The present application does not particularly limit this shape.

また、図６に示すように、本願の一実施例では、支持部材１１のそれぞれの隅部に１組の接続ユニット１４が設けられ、これにより、移動部材１２と支持部材１１との接続を強固にしながら、移動部材１２が移動するときに支持部材１１から分離することを回避する。 Further, as shown in FIG. 6, in one embodiment of the present application, a pair of connection units 14 are provided at each corner of the support member 11, thereby strengthening the connection between the movable member 12 and the support member 11. At the same time, separation of the moving member 12 from the supporting member 11 when moving is avoided.

ここでは、移動部材１２が移動するときに受力のばらつきにより傾斜したりすることを防止するために、所定断面Ｓの両側に位置する接続ユニット１４は所定断面Ｓに対して対称に分布してもよい。 Here, in order to prevent the movable member 12 from tilting due to variations in receiving force when moving, the connection units 14 located on both sides of the predetermined cross section S are distributed symmetrically with respect to the predetermined cross section S. Good too.

またなお、図６では、４組の接続ユニット１４だけが例示的に設けられるが、実際のニーズに応じては、２組、６組、８組以上の接続ユニット１４が設けられてもよく、しかも、好ましくは、接続ユニット１４の組数は偶数であり、また所定断面Ｓの両側に均等に分布している。 Furthermore, in FIG. 6, only four sets of connection units 14 are provided as an example, but depending on actual needs, two, six, eight or more sets of connection units 14 may be provided. Moreover, preferably, the number of connection units 14 is an even number, and is evenly distributed on both sides of the predetermined cross section S.
