Abstract

Disclosed is a motion guidance device provided with: a rolling element (4); a fixed-side member (2) having a rolling groove for the rolling element formed along the long direction of said fixed-side member; a moving-side member (3) coupled to the fixed-side member via the rolling element; and an end-regulation means (6), at the end of the fixed-side member, that limits the movement of the moving-side member. The end-regulation means is provided with a first member (6a) affixed to either the fixed-side member or the moving-side member, and a second member (6b) affixed to the other. Said first member (6a) is an elastic sheet having a thickness that is uniform along the direction of movement of the moving-side member. A sloped acting surface (6c) is formed on the aforementioned second member (6b). As the moving-side member moves with respect to the fixed-side member, the sloped acting surface causes the moving-side member to gradually move up the first member. If used for example on a furniture drawer or the like, the disclosed motion guidance device can prevent sudden collisions between a moving block and a stopper member when the drawer is pulled out from a frame, thereby improving the feel of the opening/closing motion of the drawer.

Description

運動案内装置Exercise guidance device
　本発明は、固定側部材の長手方向に沿って移動自在な移動側部材を備えた運動案内装置に関する。 The present invention relates to a motion guide device provided with a movable member that is movable along the longitudinal direction of a fixed member.
　この種の運動案内装置は、複数のボールと、長手方向に沿ってボールの転動溝が形成された固定側部材と、この固定側部材に前記ボールを介して組み付けられた移動側部材とから構成されている。 This type of motion guide device includes a plurality of balls, a fixed side member in which a ball rolling groove is formed along the longitudinal direction, and a moving side member assembled to the fixed side member via the ball. It is configured.
　前記運動案内装置は従来、工作機械のワークテーブルや各種搬送装置の運動案内部材として使用されている他、家具やシステムキッチンの引き出し等の運動案内部材としても使用されている。前記運動案内装置を引き出し等の案内部材として使用した場合、固定側部材の終端から前記移動側部材が抜け落ちるのを防止するために、前記固定側部材に移動側部材の移動を遮るようなストッパ部材が必要となる。 The motion guide device is conventionally used as a motion guide member for a work table of a machine tool and various conveying devices, and also as a motion guide member for drawers of furniture and a system kitchen. When the motion guide device is used as a guide member such as a drawer, a stopper member that blocks the movement of the moving side member on the fixed side member in order to prevent the moving side member from falling off from the end of the fixed side member Is required.
　このようなストッパ部材を備えた運動案内装置としては、特開2003-329036号公報に開示されているものが知られている。この運動案内装置は、一対の側壁部を有して断面略Ｕ字状に形成された軌道レールと、この軌道レールに転動体を介して組み付けられて前記側壁部間を摺動自在なスライダと、前記軌道レールの端部に取り付け取り外し自在に設けられ且つ前記スライダに当接するストッパ部材とから構成されている。 As a motion guide apparatus provided with such a stopper member, one disclosed in Japanese Patent Application Laid-Open No. 2003-329036 is known. The motion guide device includes a track rail having a pair of side wall portions and having a substantially U-shaped cross section, and a slider that is assembled to the track rail via a rolling element and is slidable between the side wall portions; And a stopper member which is detachably provided at the end of the track rail and abuts against the slider.
　この構成によれば、前記スライダが軌道レールの終端に到達した際には、当該軌道レールから前記ストッパ部材が突出しているため、このストッパ部材により前記移動ブロックが軌道レールに対して係止されるようになっている。 According to this configuration, when the slider reaches the end of the track rail, since the stopper member protrudes from the track rail, the moving block is locked to the track rail by the stopper member. It is like that.
特開2003-329036号公報JP2003-329036
　しかし、特開2003-329036号公報に開示されている運動案内装置を引き出し等の案内部材として使用したとしても、移動ブロックが固定される引き出し自体の剛性が低いと、枠体から引き出しを引き出す力により当該引き出し自体が変形してしまうおそれがある。そうなると、引き出しと枠体との間に位置する一対の運動案内装置では軌道レールに対する移動ブロックの相対的な位置ずれが生じてしまうといった不都合がある。 However, even if the motion guide device disclosed in Japanese Patent Application Laid-Open No. 2003-329036 is used as a guide member such as a drawer, if the rigidity of the drawer itself to which the moving block is fixed is low, the force to pull out the drawer from the frame body Therefore, the drawer itself may be deformed. If it becomes so, in a pair of movement guide device located between a drawer and a frame, there is a problem that a relative position shift of a movement block to a track rail will arise.
　移動ブロックの相対的な位置ずれが発生すると、一方の運動案内装置では移動ブロックが前記ストッパ部材により軌道レールに対して係止されているのに対し、他方の運動案内装置の移動ブロックは軌道レールの終端まで到達せず、軌道レールに対して係止されていない状態になる。このような状態でさらに継続して引き出しを枠体から引き出すと、他方の運動案内装置の移動ブロックがストッパ部材に唐突に突き当たることになり、もって当該引き出しをスムーズに開閉できないため、開閉する際の使用感が悪いものになってしまうといった問題があった。 When a relative displacement of the moving block occurs, in one motion guide device, the moving block is locked to the track rail by the stopper member, whereas the moving block of the other motion guide device is the track rail. Will not reach the end of the track and is not locked to the track rail. If the drawer is further pulled out from the frame in such a state, the moving block of the other motion guide device abruptly hits the stopper member, so that the drawer cannot be opened and closed smoothly. There was a problem that the feeling of use would be poor.
　本発明はこのような課題点に鑑みなされたものであり、その目的とするところは、例えば、家具やシステムキッチンの引き出し等の運動案内部材として使用した場合に、枠体から引き出しを引き出す際の移動ブロックとストッパ部材との急な衝突を防止することができ、もって引き出しを開閉する際の使用感を向上させることが可能な運動案内装置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, for example, when the drawer is pulled out from the frame when used as a motion guide member such as a drawer of furniture or a system kitchen. It is an object of the present invention to provide a motion guide device capable of preventing a sudden collision between a moving block and a stopper member, and thus improving the feeling of use when opening and closing the drawer.
　前記目的を達成するために、本発明の運動案内装置は、転動体と、長手方向に沿って前記転動体の転動溝が形成された固定側部材と、前記固定側部材に前記転動体を介して組みつけられた移動側部材と、前記固定側部材の端部において前記移動側部材の移動を制限する終端規制手段とを備えている。 In order to achieve the above object, a motion guide apparatus according to the present invention includes a rolling element, a fixed side member in which a rolling groove of the rolling element is formed along a longitudinal direction, and the rolling element on the fixed side member. And a terminal regulating means for restricting the movement of the moving member at the end of the fixed member.
　そして、前記終端規制手段は前記固定側部材又は移動側部材のいずれか一方に固定される第一部材と、前記移動側部材又は固定側部材のいずれか他方に固定される第二部材とを備えており、かかる第一部材は前記移動側部材の移動方向に沿って一様な厚さを有する弾性体シートであり、前記第二部材には前記固定側部材に対する移動側部材の移動に伴って前記第一部材に徐々に乗り上げる傾斜作用面が形成されている。 And the said termination | terminus control means is provided with the 1st member fixed to either one of the said fixed side member or the movement side member, and the 2nd member fixed to either the said movement side member or the fixed side member. The first member is an elastic sheet having a uniform thickness along the moving direction of the moving side member, and the second member is moved along with the movement of the moving side member with respect to the fixed side member. An inclined action surface that gradually climbs over the first member is formed.
　このような本発明によれば、例えば、家具やシステムキッチンの引き出し等の運動案内部材として使用した場合に、枠体から引き出しを引き出す際の移動ブロックとストッパ部材との急な衝突を防止することができ、もって引き出しを開閉する際の使用感を向上させることが可能な運動案内装置を提供することができる。 According to the present invention as described above, for example, when used as a motion guide member such as a drawer of furniture or a system kitchen, it is possible to prevent a sudden collision between the moving block and the stopper member when the drawer is pulled out from the frame. Thus, it is possible to provide an exercise guide device that can improve the feeling of use when opening and closing the drawer.

　図４は、図３のＩＶ－ＩＶ線断面図である。前記移動ブロック３の各スカート部３１ｂの内側には前記ボール４の負荷転動溝３３がそれぞれ形成されている。前記軌道レール２のボール転動溝２１と前記移動ブロック３の負荷転動溝３３は互いに対向し、ボール４が移動ブロック３と軌道レール２との間で荷重を負荷しながら転動する負荷通路３４を構成する。前記移動ブロック３には、前記ボール４が循環する無限循環路が具備されている。前記無限循環路は、前記負荷通路３４と、この負荷通路３４に対応して前記スカート部３１ｂに孔開けされるボール４の戻り通路３５と、方向転換路３６とから構成される。前記負荷通路３４内を転動し終えたボール４は、前記方向転換路３６に進入し、当該方向転換路３６内でその転動方向が逆方向に転換する。その後、前記戻り通路３５内を負荷通路３４内とは逆方向に転動する。 FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. Load rolling grooves 33 for the balls 4 are formed inside the skirt portions 31b of the moving block 3, respectively. The ball rolling groove 21 of the track rail 2 and the load rolling groove 33 of the moving block 3 face each other, and a load path through which the ball 4 rolls while applying a load between the moving block 3 and the track rail 2. 34 is configured. The moving block 3 is provided with an infinite circulation path through which the balls 4 circulate. The infinite circulation path is composed of the load path 34, a return path 35 of the ball 4 perforated in the skirt portion 31b corresponding to the load path 34, and a direction change path 36. The ball 4 that has finished rolling in the load passage 34 enters the direction changing path 36, and the rolling direction in the direction changing path 36 is reversed. After that, the return passage 35 rolls in the opposite direction to the load passage 34.
　また、前記移動ブロック２は、前記負荷通路３４及び戻り通路３５を有するブロック本体３ａと、前記方向転換路３６を有する方向転換部材３ｂとから構成されている。前記方向転換部材３ｂをブロック本体３ａに装着すると、前記無限循環路が完成する。 The moving block 2 includes a block body 3a having the load passage 34 and a return passage 35, and a direction changing member 3b having the direction changing path 36. When the direction changing member 3b is attached to the block body 3a, the endless circulation path is completed.
　本発明の運動案内装置１では軌道レール２の端部において前記移動ブロック３の移動を制限する終端規制手段６が設けられている。図５はこの終端規制手段６の第一実施形態を示す側面図である。この終端規制手段６は前記軌道レール２に対してストッパ部材５により固定される第一部材６ａと、前記移動ブロック３の端面に固定ボルト等により固定される第二部材６ｂとから構成されている。 In the motion guide device 1 according to the present invention, the end regulating means 6 for restricting the movement of the moving block 3 is provided at the end of the track rail 2. FIG. 5 is a side view showing a first embodiment of the termination regulating means 6. The terminal regulating means 6 is composed of a first member 6a fixed to the track rail 2 by a stopper member 5 and a second member 6b fixed to the end surface of the moving block 3 by a fixing bolt or the like. .
　前記第一部材６ａはリング状に形成されたゴムシートから構成されている。この第一部材６ａは前記軌道レール２に接着剤等を介して接着されると共に、前記ストッパ部材５の押圧により当該軌道レール２の端部に固定されている。 The first member 6a is composed of a rubber sheet formed in a ring shape. The first member 6 a is bonded to the track rail 2 via an adhesive or the like, and is fixed to the end of the track rail 2 by pressing the stopper member 5.
　前記第二部材６ｂは、当該第二部材の移動方向に突出する一対のアームから構成されている。これらアームの間には固定ボルトが嵌合するボルト孔が形成され（図示せず）、前記第二部材６ｂはかかる固定ボルトによって前記移動ブロック３に固定される。また、各アームの下面には例えば、一定率で勾配する傾斜作用面６ｃが形成されている。 The second member 6b is composed of a pair of arms protruding in the moving direction of the second member. A bolt hole into which a fixing bolt is fitted is formed between these arms (not shown), and the second member 6b is fixed to the moving block 3 by the fixing bolt. In addition, for example, an inclined action surface 6c that is inclined at a constant rate is formed on the lower surface of each arm.
　前記第二部材６ｂの高さ位置は、当該第二部材６ｂの傾斜作用面６ｃが第一部材６ａと干渉するように調整されている。 The height position of the second member 6b is adjusted so that the inclined action surface 6c of the second member 6b interferes with the first member 6a.
　この構成からなる運動案内装置１では先ず、前記移動ブロック３が軌道レール２の終端まで到達すると、前記第二部材６ｂに形成された傾斜作用面６ｃが軌道レール２に固定された第一部材６ａに突き当たる。 In the motion guide apparatus 1 having this configuration, first, when the moving block 3 reaches the end of the track rail 2, the first member 6a in which the inclined action surface 6c formed on the second member 6b is fixed to the track rail 2. I hit it.
　その後、前記移動ブロック３を軌道レール２の終端に向けて移動させるにつれ、前記傾斜作用面６ｃが一定率の勾配で構成されていることから、前記第二部材６ｂは第一部材６ａに徐々に乗り上げていくことになる。この傾斜作用面６ｃの乗り上げに伴って、前記第一部材６ａは軌道レール２の長手方向に徐々に弾性変形する。 Thereafter, as the moving block 3 is moved toward the end of the track rail 2, the inclined working surface 6c is configured with a constant gradient, so that the second member 6b is gradually moved to the first member 6a. You will get on. The first member 6a is gradually elastically deformed in the longitudinal direction of the track rail 2 as the inclined working surface 6c rides up.
　前記第一部材６ａに対する傾斜作用面６ｃの乗り上がる範囲が大きくなるにつれ、当該第一部材６ａの変形量が大きくなっていく。これにより、前記移動ブロック３に対する移動抵抗は第一部材６ａの存在範囲Ｌ内で徐々に増大していく。 The amount of deformation of the first member 6a increases as the range on which the inclined working surface 6c rides on the first member 6a increases. Thereby, the movement resistance with respect to the said movement block 3 increases gradually within the presence range L of the 1st member 6a.
　すなわち、運動案内装置１では移動ブロック３に対する移動抵抗の増大により、従来の運動案内装置の如く、前記移動ブロックがストッパ部材に突き当たっていきなり係止されるのではなく、当該第一部材６ａの存在範囲Ｌ内で移動ブロック３の動きが徐々に重くなっていき、最終的には移動ブロック３が軌道レール２に対して係止される。 That is, in the motion guide device 1, due to an increase in the movement resistance with respect to the moving block 3, the moving block does not abut against the stopper member and is not locked as in the conventional motion guide device, but the presence of the first member 6a. Within the range L, the movement of the moving block 3 gradually becomes heavier, and finally the moving block 3 is locked to the track rail 2.
　尚、図５では前記終端規制手段６が設けられた軌道レール２の一端側のみを示しているが、用途によっては終端規制手段６を軌道レール２の一端又は両端に固定するかを任意に選択することができる。 In FIG. 5, only one end side of the track rail 2 provided with the end regulation means 6 is shown. However, depending on the application, it is arbitrarily selected whether the end regulation means 6 is fixed to one end or both ends of the track rail 2. can do.
　また、図１に示されるように、単一の軌道レール２に対して複数の移動ブロック３を組み付けた場合、前記軌道レール２の終端に対応した移動ブロック３の端面に対して前記終端規制手段６を取付ける。 In addition, as shown in FIG. 1, when a plurality of moving blocks 3 are assembled to a single track rail 2, the termination regulating means with respect to the end surface of the moving block 3 corresponding to the termination of the track rail 2. 6 is installed.
　更に、本実施形態では前記第一部材６ａがリング状に形成されているが、当該第一部材６ａの存在範囲Ｌが保たれるのであれば、四角形等に形成されていても差し支えない。 Furthermore, in the present embodiment, the first member 6a is formed in a ring shape. However, the first member 6a may be formed in a rectangular shape or the like as long as the existence range L of the first member 6a is maintained.
　また、前記移動ブロック３に対する移動抵抗の増大率を大きくさせたい場合には、前記第一部材６ａの厚さや前記第二部材６ｂの傾斜作用面６ｃの勾配等を任意に変化させることで、前記移動ブロック３に対する移動抵抗の増大率を大きくさせることができる。 Further, when it is desired to increase the rate of increase of the movement resistance with respect to the moving block 3, by arbitrarily changing the thickness of the first member 6a, the gradient of the inclined working surface 6c of the second member 6b, etc. The increase rate of the movement resistance with respect to the movement block 3 can be increased.
　図６は第二実施形態の終端規制手段６０の示す側面図である。この終端規制手段６０では、軌道レール２に固定される第一部材６０ａの上面には傾斜作用面６０ｃが形成される一方、移動ブロック３に固定される第二部材６０ｂの下面には弾性シート６０ｄが設けられている。この終端規制手段６０は第一実施形態に係る終端規制手段６と同様の作用効果を奏するものであり、本発明の終端規制手段はいずれの態様も含むものである。 FIG. 6 is a side view showing the end regulating means 60 of the second embodiment. In the terminal regulating means 60, an inclined action surface 60c is formed on the upper surface of the first member 60a fixed to the track rail 2, while an elastic sheet 60d is formed on the lower surface of the second member 60b fixed to the moving block 3. Is provided. The termination regulating means 60 has the same effect as the termination regulating means 6 according to the first embodiment, and the termination regulating means of the present invention includes any aspect.
　このように構成された本実施形態の運動案内装置を引き出し等の運動案内部材として使用した際に、引き出し形状の変形により一対の運動案内装置の間で移動ブロックの相対的な位置ずれが生じたとしても、引き出しを開閉する際の使用感の改善を図ることができる。すなわち、一対の運動案内装置の間で移動ブロックの相対的な位置ずれが生じていると、一方の運動案内装置では第二部材が第一部材に乗り上がり始めたとしても、他方の運動案内装置では前記第二部材の傾斜作用面が第一部材の端部に到達せず、当該第二部材が第一部材に乗り上がっていない状態となる。 When the motion guide device of the present embodiment configured as described above was used as a motion guide member such as a drawer, a relative displacement of the moving block occurred between the pair of motion guide devices due to deformation of the drawer shape. However, it is possible to improve the feeling of use when opening and closing the drawer. That is, when the relative displacement of the moving block occurs between the pair of motion guide devices, even if the second member starts to ride on the first member in one motion guide device, the other motion guide device Then, the inclined action surface of the second member does not reach the end of the first member, and the second member is not on the first member.
　この状態から継続して引き出しを枠体から引き出すと、前者の運動案内装置では第一部材への第二部材の乗り上げにより、移動ブロックの軌道レールに対する動きが重くなる。この間に、後者の運動案内装置でも前記第二部材が第一部材に乗り上がり始める。 When the drawer is continuously pulled out from the frame body from this state, the movement of the moving block with respect to the track rail becomes heavy due to the second member riding on the first member in the former motion guide device. During this time, the second member starts to ride on the first member even in the latter motion guide device.
　このようにして、引き出しを枠体から引き出した際に双方の運動案内装置では終端規制手段により、夫々の移動ブロックの移動速度が徐々に減衰されていき、最終的には移動ブロックが軌道レールに対して係止される。 In this way, when the drawer is pulled out from the frame, the movement speed of each moving block is gradually attenuated by the terminal regulating means in both motion guide devices, and finally the moving block becomes the track rail. It is locked against.
　すなわち、本実施形態の運動案内装置を引き出し等の案内部材として適用した場合には、移動ブロックが軌道レールの終端に到達した際に、双方の運動案内装置において移動ブロックとストッパ部材との急な衝突を防止することが可能となる。この結果、移動ブロックの相対的な位置ずれが発生している状態で引き出しを枠体から引き出そうとしても、左右いずれか一方の運動案内装置の移動ブロックだけがストッパ部材に唐突に突き当たることがなく、もって引き出しを枠体から引き出した際の使用感を向上させることが可能となる。 That is, when the motion guide device of this embodiment is applied as a guide member such as a drawer, when the moving block reaches the end of the track rail, both the motion guide devices have a sudden movement between the moving block and the stopper member. A collision can be prevented. As a result, even when trying to pull out the drawer from the frame while the relative displacement of the moving block is occurring, only the moving block of either the left or right motion guide device does not hit the stopper member suddenly. Thus, it is possible to improve the feeling of use when the drawer is pulled out from the frame.
　尚、本実施形態の運動案内装置では軌道レールに固定された第一部材がゴムシートから構成されているが、前記移動ブロックに固定された第二部材に押圧されて弾性変形する部材であればよく、例えば、樹脂シートから構成されても差し支えない。 In the motion guide device according to the present embodiment, the first member fixed to the track rail is made of a rubber sheet. However, as long as the member is elastically deformed by being pressed by the second member fixed to the moving block. For example, it may be made of a resin sheet.
　また、前記第一部材を軌道レールに対して強固に固定することができるのであれば、ストッパ部材を利用して当該第一部材を軌道レールに対して押圧する必要はない。 Further, if the first member can be firmly fixed to the track rail, it is not necessary to press the first member against the track rail using the stopper member.
　更に、上記第一及び第二実施形態では前記第二部材が移動ブロックの端面から突出した状態で固定されているが、前記軌道レールに固定された第一部材に対応する位置であれば、当該移動ブロックの軸方向内部に当該第二部材を設けても差し支えない。 Furthermore, in said 1st and 2nd embodiment, although the said 2nd member is being fixed in the state protruded from the end surface of a movement block, if it is a position corresponding to the 1st member fixed to the said track rail, The second member may be provided inside the moving block in the axial direction.
　図７は本発明の運動案内装置の第三実施形態を示すものである。以上説明してきた第一及び第二実施形態では本発明をボールの無限循環路を備えた直線案内装置に適用しているが、この実施形態では有限スライドレールユニットに適用している。かかるスライドレールユニット７０は長手方向に沿って一対のボール転走部を曲げ起こしてチャネル状に形成されたアウタレール７１と、同じく一対のボール転走部を曲げ起こしてチャネル状に形成されたインナレール７２と、これらアウタレール７１のボール転走部の内側とインナレール７２のボール転走部の外側を転走する多数のボール７３と、前記アウタレール７１とインナレール７２との間でボール７３を所定の間隔で整列させるリテーナ７４とから構成されている。 FIG. 7 shows a third embodiment of the motion guide device of the present invention. In the first and second embodiments described above, the present invention is applied to a linear guide device having an infinite circulation path for balls. In this embodiment, the present invention is applied to a finite slide rail unit. The slide rail unit 70 includes an outer rail 71 formed in a channel shape by bending a pair of ball rolling portions along the longitudinal direction, and an inner rail formed in a channel shape by bending the pair of ball rolling portions. 72, a number of balls 73 rolling inside the ball rolling part of the outer rail 71 and the outside of the ball rolling part of the inner rail 72, and a ball 73 between the outer rail 71 and the inner rail 72. The retainer 74 is arranged at intervals.
　この実施形態では、インナーレール７２の端部に弾性体シートとしての第一部材７５が固定される一方、アウターレール７１の端部には傾斜作用面を有する第二部材７６が固定されている。 In this embodiment, a first member 75 as an elastic sheet is fixed to the end portion of the inner rail 72, while a second member 76 having an inclined action surface is fixed to the end portion of the outer rail 71.
　この構成によっても、前述した第一実施形態及び第二実施形態と同様の作用効果が奏され、引き出しの案内部材として利用した際に使用感を向上させることができる。 Also with this configuration, the same operational effects as the first embodiment and the second embodiment described above can be obtained, and the usability can be improved when used as a guide member for the drawer.
　但し、第三の実施形態においては、前記アウターレール７１に対してインナーレール７２を完全に収納した場合、ボール７３を配列するリテーナ７４はアウターレール７１の長手方向の中央に位置するため、アウターレール７１及びインナーレール７２の端部に配置された終端規制手段とボール７３の距離が離れてしまう。かかる場合、インナーレール７２がアウターレール７３に対して傾きを生じてしまうと前記第一部材７５と第二部材７６との間で充分な押圧が得られず、インナーレール７２の移動を充分に減衰できない可能性がある。これに対し、第一及び第二実施形態の如く、無限循環路を介して移動ブロックが軌道レールに組み付けられる直線案内装置では、移動ブロックに固定された第一部材又は第二部材は常にボール列との距離が近いため、より終端規制手段の効果を確実に得られる。 However, in the third embodiment, when the inner rail 72 is completely stored in the outer rail 71, the retainer 74 for arranging the balls 73 is located at the center in the longitudinal direction of the outer rail 71. The distance between the end restricting means disposed at the end portions of 71 and the inner rail 72 and the ball 73 is increased. In such a case, if the inner rail 72 is inclined with respect to the outer rail 73, sufficient pressure cannot be obtained between the first member 75 and the second member 76, and the movement of the inner rail 72 is sufficiently attenuated. It may not be possible. On the other hand, in the linear guide device in which the moving block is assembled to the track rail through the infinite circulation path as in the first and second embodiments, the first member or the second member fixed to the moving block is always a ball train. Therefore, the effect of the terminal regulating means can be obtained more reliably.
