Description

運動案内装置のロック機構及びこれを用いた転がり案内装置Lock mechanism of motion guide device and rolling guide device using the same
　本発明は、軌道レールに沿ってスライドブロックが自在に移動する運動案内装置において、当該スライドブロックを前記軌道レールの任意の位置に確実に固定するためのロック機構に関する。 The present invention relates to a locking mechanism for securing a slide block to an arbitrary position of the track rail in a motion guide device in which the slide block freely moves along the track rail.
　この種の運動案内装置としては、軌道レールと、前記軌道レールに組み付けられて当該軌道レールの長手方向に沿って自在に移動可能なスライドブロックと、を備えたものが知られている。この運動案内装置には、低摩擦係数の樹脂摺接部材が前記軌道レールと前記スライドブロックとの間に設けられた滑り案内装置や、前記スライドブロックが多数の転動体を介して前記軌道レールに組み付けられた転がり案内装置が含まれている。 As such a motion guide device, there is known a track rail and a slide block assembled to the track rail and freely movable along the longitudinal direction of the track rail. In this motion guide device, a slide guide device in which a resin sliding contact member having a low coefficient of friction is provided between the track rail and the slide block, or the slide block is connected to the track rail via a large number of rolling elements. An assembled rolling guide device is included.
　従来、この種の運動案内装置は主に各種工作機械や搬送装置といった産業機械の直線案内部又は曲線案内部に多用されていたが、近年ではその用途が拡大してきている。例えば、特許文献１には航空機の機内における座席位置の調節システムが開示されており、この調節システムに前記運動案内装置を使用することが可能である。すなわち、航空機の機内の床面に前記軌道レールを配置する一方、座席の脚部を前記スライドブロックに接続することで、機内において前記座席を床面上で容易に移動させ、座席数やその配列ピッチを柔軟に変更することが可能となる。 Conventionally, this type of motion guide device has been widely used mainly for linear guides or curve guides of industrial machines such as various machine tools and transport devices, but in recent years its use has been expanded. For example, Patent Document 1 discloses a system for adjusting the seat position in the plane of an aircraft, and it is possible to use the motion guide device in this system. That is, while the track rail is disposed on the floor of the aircraft, the legs of the seat are connected to the slide block, so that the seat can be easily moved on the floor and the number of seats and their arrangement can be obtained. It is possible to flexibly change the pitch.

　しかし、前記運動案内装置を座席位置の調節システムに使用する場合には、前記座席を床面上の特定の位置に移動不能に固定する必要があり、そのためには前記スライドブロックを軌道レール上の任意の位置に確実に固定できることが必要とされる。 However, when the motion guide device is used in a seat position adjustment system, it is necessary to immovably fix the seat at a specific position on the floor surface. It needs to be able to be fixed securely in any position.
　また、前記運動案内装置の用途によっては、前記軌道レールに対する前記スライドブロックの固定状態が意図せずして解除されないよう、二重の安全策を講じることが必要となる。 In addition, depending on the application of the motion guide device, it is necessary to take double safety measures so that the fixed state of the slide block with respect to the track rail is not released unintentionally.
　本発明はこのような課題に鑑みなされたものであり、その目的とするところは、前記軌道レールの長手方向の任意の位置に前記スライドブロックを確実に固定することができ、しかも当該固定状態が意図せずして解除されることのないロック機構を提供することにある。 The present invention has been made in view of such problems, and the object of the present invention is to securely fix the slide block at an arbitrary position in the longitudinal direction of the track rail, and the fixed state is An object of the present invention is to provide a locking mechanism that is not unintentionally released.
　すなわち、本発明は、軌道レールの長手方向の任意の位置にスライドブロックを固定するためのロック機構であって、前記軌道レールに対してその長手方向に所定のピッチで配列された固定孔と、前記スライドブロックに保持され、前記固定孔から離脱した開放位置及び当該固定孔に挿入されたロック位置に設定自在なブレーキピンと、前記ブレーキピンを前記ロック位置に向けて付勢する予圧部材と、前記ロック位置に設定されたブレーキピンに係合して、当該プレーキピンの前記開放位置への移動を防止する規制部材と、を備えている。 That is, the present invention is a lock mechanism for fixing the slide block at any position in the longitudinal direction of the track rail, wherein the fixing holes are arranged at a predetermined pitch in the longitudinal direction with respect to the track rail; A brake pin which is held by the slide block and can be set to an open position separated from the fixing hole and a lock position inserted into the fixing hole, a prestressing member for biasing the brake pin toward the locking position, and And a restricting member engaged with the brake pin set in the lock position to prevent the movement of the plate in the open position.
　本発明のロック機構によれば、前記ブレーキピンをロック位置に設定することで、前記スライドブロックを前記軌道レールに対して固定することが可能となる。この際、前記予圧部材が前記ブレーキピンを前記ロック位置に向けて付勢されているので、当該ブレーキピンが意図せずしてロック位置から離脱することはない。また、ロック位置に設定されたブレーキピンに対しては前記規制部材が係合しているので、仮に前記ブレーキピンに対して前記固定孔を抜け出す方向の加速度が作用したとしても、当該ブレーキピンを前記固定孔内のロック位置に保持すことができ、前記軌道レールに対する前記スライドブロックの固定状態を良好に維持することが可能である。 According to the lock mechanism of the present invention, the slide block can be fixed to the track rail by setting the brake pin in the lock position. At this time, since the preloading member is biased to move the brake pin toward the lock position, the brake pin will not be unintentionally released from the lock position. Further, since the restricting member is engaged with the brake pin set in the lock position, even if an acceleration in the direction of coming out of the fixing hole acts on the brake pin, the brake pin It can be held in a locked position in the fixing hole, and the fixed state of the slide block with respect to the track rail can be well maintained.

It fits through the gap. The ridges 22 of the slide block 2 and the concave grooves 11 of the track rail 1 are compatible with each other only when the slide block 2 is assembled to the track rail 1 from the longitudinal end of the track rail 1 .
　このため、前記スライドブロック２から前記軌道レール１に対して、極度に大きな外部荷重が当該軌道レール１を前記ベースレール３から浮き上がらせる方向へ作用したとしても、前記スライドブロック２が前記軌道レール１から分離することがないようになっている。すなわち、本実施形態に示すように、この転がり案内装置を座席の位置調整システムに使用した場合、前記スライドブロックに結合された座席の脚部は前記軌道レールの長手方向へは移動自在だが、当該脚部は前記軌道レールが結合されたベースレール３から分離不能であり、座席をベースレール３が固定された床面に対して確実に保持することが可能である。 Therefore, even if an extremely large external load acts on the track rail 1 from the slide block 2 in such a direction that the track rail 1 is lifted from the base rail 3, the slide block 2 does not move the track rail 1. It is designed not to be separated from That is, as shown in the present embodiment, when this rolling guide device is used in the seat position adjusting system, the leg portion of the seat coupled to the slide block is movable in the longitudinal direction of the track rail, but The legs are inseparable from the base rail 3 to which the track rail is connected, and it is possible to hold the seat securely to the floor surface to which the base rail 3 is fixed.
　前記ベースレール３は長手方向に沿って延びる溝部３０を有してチャネル状に形成されており、前記溝部３０は底部３１及び一対の側壁３２によって囲まれている。前記一対の側壁３２の上端には保持部３３がそれぞれ設けられており、これら保持部３３は前記ベースレール３の長手方向に沿って延びると共に前記溝部３０上に張り出している。前記溝部３０上に張り出した一対の保持部３３の間にはスリット状の開口部が設けられている。また、前記ベースレール３には前記保持部３３を切り欠くようにして複数の嵌入孔３４が形成されている。これら嵌入孔３４は前記ベースレール３の長手方向に沿って一定の間隔で設けられており、前記保持部３３は前記嵌入孔３４で分断され、当該嵌入孔３４の形成位置においては前記開口部が拡幅されている。 The base rail 3 is formed in a channel shape with a groove 30 extending along the longitudinal direction, and the groove 30 is surrounded by the bottom 31 and a pair of side walls 32. At the upper end of the pair of side walls 32, holding portions 33 are respectively provided, and the holding portions 33 extend along the longitudinal direction of the base rail 3 and project onto the groove portion 30. A slit-like opening is provided between the pair of holding portions 33 protruding above the groove 30. Further, a plurality of insertion holes 34 are formed in the base rail 3 so as to cut out the holding portion 33. The insertion holes 34 are provided at regular intervals along the longitudinal direction of the base rail 3, the holding portion 33 is divided by the insertion holes 34, and the openings are formed at the positions where the insertion holes 34 are formed. It has been widened.
　前記ベースレール３の溝部３０内には固定端子３５が挿入されている。前記軌道レール１のボルト取付け孔１２に挿入された六角穴付きボルトの先端は前記固定端子３５に螺合しており、当該六角穴付きボルトを締結すると、前記ベースレール３の溝部３０内で前記固定端子３５が前記軌道レール１に向けて引き上げられ、当該固定端子３５と前記軌道レール１との間に前記ベースレール３の保持部３３が挟み込まれるようになっている。これにより、前記六角穴付きボルトを締結すると、前記軌道レール１が前記ベースレール３に対して確実に固定される。 The fixed terminal 35 is inserted into the groove 30 of the base rail 3. The tip of the hexagonal socket bolt inserted into the bolt mounting hole 12 of the track rail 1 is screwed into the fixed terminal 35, and when the hexagonal socket bolt is tightened, the groove 30 of the base rail 3 The fixed terminal 35 is pulled up toward the track rail 1, and the holding portion 33 of the base rail 3 is sandwiched between the fixed terminal 35 and the track rail 1. Thus, when the hexagonal socket bolt is fastened, the track rail 1 is securely fixed to the base rail 3.
　一方、前記軌道レール１の上面には長手方向に沿って所定の間隔で固定穴１３が設けられている。前記固定穴１３には前記スライドブロック２に保持されたブレーキピン５が挿入される。図１に示した実施形態においては、前記ボルト取付け孔１２と前記固定穴１３の形成間隔は同一であり、これらボルト取付け孔１２と固定穴１３が前記軌道レール１の長手方向に沿って交互に配列されている。前記固定穴１３の内周面はテーパ状に形成されており、当該固定穴１３の内径は穴底面に近づくにつれて徐々に小さくなっている。 On the other hand, fixing holes 13 are provided on the upper surface of the track rail 1 at predetermined intervals along the longitudinal direction. The brake pin 5 held by the slide block 2 is inserted into the fixing hole 13. In the embodiment shown in FIG. 1, the formation intervals of the bolt mounting holes 12 and the fixing holes 13 are the same, and these bolt mounting holes 12 and the fixing holes 13 alternate along the longitudinal direction of the track rail 1. It is arranged. The inner peripheral surface of the fixing hole 13 is formed in a tapered shape, and the inner diameter of the fixing hole 13 gradually decreases as it approaches the bottom of the hole.
　前記固定孔に挿入されるブレーキピン５は前記スライドブロック２に保持されている。前記ブレーキピン５は略円柱状に形成されており、軸方向が前記軌道レールの長手方向に対して直交した状態で前記スライドブロック２上に突出している。前記スライドブロック２には前記ブレーキピン５の外径よりも僅かに大きな内径を有する貫通穴が設けられており、前記ブレーキピン５の下端は当該貫通孔に挿入されている。また、前記貫通孔は前記軌道レール１の固定穴１３に対向する位置に存在している。従って、前記スライドブロック２の貫通孔に挿入された前記ブレーキピン５を軸方向へ上下動させることにより、当該ブレーキピン５の下端が前記固定穴１３に対して抜き差しされるようになっている。すなわち、前記ブレーキピン５は、下端が固定穴１３に挿入されたロック位置と、当該下端が前記固定穴１３から離脱した開放位置との間を、自在に移動することが可能であり、前記ブレーキピン５がロック位置に設定された状態では前記軌道レール１に対する前記スライドブロック２の移動が禁止される。 The brake pin 5 inserted into the fixing hole is held by the slide block 2. The brake pin 5 is formed in a substantially cylindrical shape, and protrudes on the slide block 2 in a state where the axial direction is orthogonal to the longitudinal direction of the track rail. The slide block 2 is provided with a through hole having an inner diameter slightly larger than the outer diameter of the brake pin 5, and the lower end of the brake pin 5 is inserted into the through hole. Further, the through hole is present at a position facing the fixing hole 13 of the track rail 1. Therefore, the lower end of the brake pin 5 is inserted into and removed from the fixing hole 13 by moving the brake pin 5 vertically inserted in the through hole of the slide block 2 in the axial direction. That is, the brake pin 5 can freely move between the lock position where the lower end is inserted into the fixing hole 13 and the open position where the lower end is separated from the fixing hole 13, and the brake When the pin 5 is set to the lock position, the movement of the slide block 2 with respect to the track rail 1 is prohibited.
　前記固定穴１３に挿入されるブレーキピン５の下端にはテーパ形状の先端部５０が設けられている。この先端部５０は前記軌道レール１の固定穴１３の内周面の形状と合致したテーパ状の外周面を有しており、前記ブレーキピン５が前記ロック位置に設定された状態では、前記先端部５０の外周面が前記固定穴１３の内周面と緊密に接触する。 A tapered tip portion 50 is provided at the lower end of the brake pin 5 inserted into the fixing hole 13. The front end portion 50 has a tapered outer peripheral surface that matches the shape of the inner peripheral surface of the fixing hole 13 of the track rail 1, and in the state where the brake pin 5 is set to the lock position, the front end The outer peripheral surface of the portion 50 closely contacts the inner peripheral surface of the fixing hole 13.
　一方、前記スライドブロック２には金属板を折り曲げて形成したピンホルダ６が固定されている。前記プレーキピン５の上端は前記ピンホルダ６を貫通しており、当該ピンホルダ６は前記ブレーキピン５が前記ロック位置と前記開放位置との間を上下動する際のガイドの機能を有している。また、前記ブレーキピン５と前記ピンホルダ６との間にはコイルスプリングからなる予圧部材７が設けられており、当該ブレーキピン５は常に軌道レール１に向けて付勢されている。従って、前記ブレーキピン５に対してこれをピンホルダ６の方向へ引き上げる外力が何ら作用していない状態では、当該ブレーキピン５は常に前記ロック位置に設定され、前記先端部５０は前記予圧部材７の付勢力によって前記軌道レール１の固定穴１３に押し込まれている。 On the other hand, a pin holder 6 formed by bending a metal plate is fixed to the slide block 2. The upper end of the brake pin 5 penetrates the pin holder 6, and the pin holder 6 has a function of guiding when the brake pin 5 moves up and down between the lock position and the open position. Further, a preload member 7 formed of a coil spring is provided between the brake pin 5 and the pin holder 6, and the brake pin 5 is always urged toward the track rail 1. Therefore, the brake pin 5 is always set to the lock position in a state where no external force pulling up the brake pin 5 in the direction of the pin holder 6 is acting on the brake pin 5, and the tip portion 50 is of the preload member 7. It is pushed into the fixing hole 13 of the track rail 1 by the biasing force.
　また、前記ブレーキピン５には周方向に沿って規制溝５１が設けられる一方、前記ピンホルダ６には前記規制溝に係合する規制部材８が設けられている。図３及び図４は前記規制部材８の構成を示す図である。前記規制部材８は前記規制溝５１に嵌入する規制駒５２を有しており、当該規制駒５２は弾性部材５３によって前記ブレーキピン５の軸方向と直交する方向へ付勢されている。前記規制駒５２は前記プレーキピン５が前記開放位置に設定された状態では前記規制溝５１に嵌入せず、前記弾性部材５３によって当該ブレーキピン５の外周面に押し付けられている（図３参照）。一方、前記ブレーキピン５が前記ロック位置に設定されると、前記規制駒５２は前記規制溝５１と対向し、前記弾性部材５３の付勢力によって当該規制溝５１に嵌入する（図４参照）。 Further, while the control pin 51 is provided with a control groove 51 along the circumferential direction, the pin holder 6 is provided with a control member 8 engaged with the control groove. 3 and 4 are views showing the configuration of the regulating member 8. As shown in FIG. The restricting member 8 has a restricting piece 52 fitted in the restricting groove 51, and the restricting piece 52 is biased by the elastic member 53 in a direction orthogonal to the axial direction of the brake pin 5. The restricting piece 52 does not fit into the restricting groove 51 in the state where the brake pin 5 is set to the open position, and is pressed against the outer peripheral surface of the brake pin 5 by the elastic member 53 (see FIG. 3). On the other hand, when the brake pin 5 is set to the lock position, the restriction piece 52 faces the restriction groove 51, and is fitted into the restriction groove 51 by the biasing force of the elastic member 53 (see FIG. 4).
　本実施形態において、前記規制部材８はボールプランジャにより実現されている。すなわち、図２に示すように、前記ピンホルダ６には前記規制部材８としてのボールプランジャが固定され、当該ボールプランジャの先端に位置するボールが前記規制駒５２として前記ブレーキピン５の外周面に押圧されている。前記ボールプランジャは前記ピンホルダ６に螺合しており、ロックナット８０によって当該ピンホルダ６に対する固定がなされている。 In the present embodiment, the restriction member 8 is realized by a ball plunger. That is, as shown in FIG. 2, a ball plunger as the restricting member 8 is fixed to the pin holder 6, and a ball located at the tip of the ball plunger presses against the outer peripheral surface of the brake pin 5 as the restricting piece 52. It is done. The ball plunger is screwed into the pin holder 6, and is fixed to the pin holder 6 by a lock nut 80.
　このように構成された本発明の転がり案内装置においては、前記ブレーキピン５に外力を作用させてこれを前記開放位置に保持した状態の際に、当該ブレーキピン５の先端部５０が前記軌道レール１の固定穴１３から抜け出し、前記軌道レール１に対する前記スライドブロック２の移動が可能となる。前記ブレーキピン５にはこれをロック位置へ押し込む付勢力が前記予圧部材７から作用しているので、前記外力を除去すると、当該ブレーキピン５は軌道レール１の上面に向けて押圧される。このため、前記スライドブロック２を移動させ、前記ブレーキピン５が前記軌道レール１の固定穴１３の対向位置に到達すると、当該ブレーキピン５は前記固定穴１３に嵌入して前記ロック位置に設定される。 In the rolling guide device of the present invention configured as described above, when the external force is applied to the brake pin 5 and the external force is held in the open position, the tip portion 50 of the brake pin 5 is the track rail The slide block 2 can be moved out of the fixing hole 13 of 1 and the track rail 1 can be moved. Since the biasing force for pushing the brake pin 5 to the lock position acts from the preload member 7, the brake pin 5 is pressed toward the upper surface of the track rail 1 when the external force is removed. Therefore, when the slide block 2 is moved and the brake pin 5 reaches the position opposite to the fixing hole 13 of the track rail 1, the brake pin 5 is fitted into the fixing hole 13 and set to the lock position. Ru.
　前記ブレーキピン５の先端部５０の外周面のテーパ形状は前記固定穴１３の内周面のテーパ形状と合致していることから、当該ブレーキピン５がロック位置に設定されると、前記先端部５０は前記予圧部材７の押圧力によって固定穴１３と隙間なく嵌合する。これにより、前記ブレーキピン５は前記軌道レール１に対してガタツキなく固定され、前記スライドブロック２は前記軌道レール１に対して移動不能となって、当該軌道レール１上に固定される。従って、本実施形態の転がり案内装置では、前記固定穴１３が存在する位置であれば、前記スライドブロック２を前記軌道レール１に沿った任意の位置に確実に固定することが可能である。 The tapered shape of the outer peripheral surface of the distal end portion 50 of the brake pin 5 matches the tapered shape of the inner peripheral surface of the fixing hole 13, so that when the brake pin 5 is set to the lock position, the distal end portion The reference numeral 50 is fitted with the fixing hole 13 without a gap by the pressing force of the preloading member 7. Thereby, the brake pin 5 is fixed to the track rail 1 without rattling, and the slide block 2 becomes immovable with respect to the track rail 1 and fixed on the track rail 1. Therefore, in the rolling guide device of the present embodiment, the slide block 2 can be reliably fixed at any position along the track rail 1 as long as the fixing hole 13 is present.
　そして、前記ブレーキピン５は前記予圧部材７によって常にロック位置へ付勢されていることから、前記転がり案内装置に対して振動が作用しても、当該ブレーキピン５が意図せずして前記軌道レール１の固定穴１３から抜け出すことはなく、前記軌道レール１に対する前記スライドブロック２の固定状態は確実に維持される。また、ロック位置に設定された前記ブレーキピン５の規制溝５１には前記規制駒５２が嵌入しているので、当該規制駒５２が前記規制溝５１から抜け出さない限り、前記ブレーキピン５を前記固定穴１３から引き抜いてロック位置から開放位置へ後退させることは不能である。 And since the brake pin 5 is always urged to the lock position by the preload member 7, even if vibration acts on the rolling guide device, the brake pin 5 unintentionally causes the track It does not come out of the fixing hole 13 of the rail 1 and the fixing state of the slide block 2 with respect to the track rail 1 is reliably maintained. Further, since the restriction piece 52 is inserted into the restriction groove 51 of the brake pin 5 set at the lock position, the brake pin 5 is fixed as long as the restriction piece 52 does not come out of the restriction groove 51. It is impossible to withdraw from the hole 13 and retract from the locked position to the open position.
　加えて、前記予圧部材７による前記ブレーキピン５の押圧方向と前記弾性部材５３による前記規制駒５２の押圧方向とは互いに直交しているので、いずれか一方向へ極端に大きな加速度の振動が作用したとしても、前記予圧部材７による押圧力または前記弾性部材５３による押圧力のいずれかは維持される。このため、前記転がり案内装置に対して過大な加速度の振動が作用した場合であっても、ブレーキピン５をロック位置に確実に保持することが可能である。 In addition, since the pressing direction of the brake pin 5 by the preloading member 7 and the pressing direction of the restriction piece 52 by the elastic member 53 are orthogonal to each other, vibration with extremely large acceleration acts in any one direction. Even in this case, either the pressing force by the preloading member 7 or the pressing force by the elastic member 53 is maintained. For this reason, even when vibration of excessive acceleration acts on the rolling guide device, it is possible to reliably hold the brake pin 5 in the lock position.
　仮に前記予圧部材７が破損して、前記ブレーキピン５を前記固定穴１３に押し込む力が失われた場合であっても、当該ブレーキピン５がロック位置から開放位置へ移動してしまうことはなく、前記軌道レール１に対する前記スライドブロック２の固定状態を確実に維持することが可能である。 Even if the preload member 7 is broken and the force for pushing the brake pin 5 into the fixing hole 13 is lost, the brake pin 5 does not move from the lock position to the release position. It is possible to reliably maintain the fixed state of the slide block 2 with respect to the track rail 1.
　また、前記規制駒５２をブレーキピン５に向けて押圧する前記弾性部材５３が破損して、当該規制駒５２が前記ブレーキピン５の規制溝５１から離脱してしまった場合であっても、前記予圧部材７が前記ブレーキピン５に対してこれを固定穴１３に押し込む付勢力を及ぼしていることから、当該ブレーキピン５が意図せずして前記軌道レール１の固定穴１３から抜け出すことはない。従って、この場合でも前記軌道レール１に対する前記スライドブロック２の固定状態を確実に維持することが可能である。 Further, even when the elastic member 53 for pressing the restriction piece 52 toward the brake pin 5 is broken and the restriction piece 52 is separated from the restriction groove 51 of the brake pin 5, Since the preloading member 7 exerts an urging force to push the brake pin 5 into the fixing hole 13, the brake pin 5 is not unintentionally pulled out of the fixing hole 13 of the track rail 1. . Accordingly, even in this case, it is possible to reliably maintain the fixed state of the slide block 2 with respect to the track rail 1.
　すなわち、本実施形態の運動案内装置のロック機構によれば、大きな加速度が作用する可能性の高い部位に当該運動案内装置を利用したとしても、前記軌道レールに対する前記スライドブロックの固定状態を確実に維持することが可能となる。このため、例えば航空機の機内における座席位置の調節システムのように、運動案内装置の用途の拡大を図ることが可能となる。 That is, according to the lock mechanism of the motion guide device of the present embodiment, even if the motion guide device is used at a portion where a large acceleration is likely to be applied, the fixed state of the slide block with respect to the track rail can be assured. It becomes possible to maintain. For this reason, it becomes possible to aim at the expansion of the use of a motion guidance device like the adjustment system of the seat position in the inflight of an aircraft, for example.
　尚、図１及び図２で示した前記軌道レール１や前記スライドブロック２の形状及び構造はあくまでも本発明のロック装置を適用可能な運動案内装置の一例であり、例えば前記運動案内装置の用途に応じて、適宜設計変更することが可能である。また、図１及び図２では本発明のロック機構の適用対象として、多数の転動体を介して前記軌道レール１と前記スライドブロック２とが組み付けられた転がり案内装置を説明したが、本発明の適用対象はこれに限られるものではなく、例えば軌道レール１に対してスライドブロック２が低摩擦係数の摺接部材を介して滑り接触する滑り案内装置であっても差し支えない。 The shapes and structures of the track rail 1 and the slide block 2 shown in FIGS. 1 and 2 are merely examples of the motion guide device to which the lock device of the present invention can be applied. For example, for the use of the motion guide device Accordingly, it is possible to appropriately change the design. Moreover, although FIG.1 and FIG.2 demonstrated the rolling guide apparatus with which the said track rail 1 and the said slide block 2 were assembled | attached through many rolling elements as application object of the lock mechanism of this invention. The application object is not limited to this. For example, a slide guide device in which the slide block 2 is in sliding contact with the track rail 1 via a low friction coefficient sliding contact member may be used.
