Abstract

This motion guide device comprises a track member (11), a movement member body part (17), a pair of lid members (30), and a plurality of rolling elements (12). A movement member (13), which is formed of the movement member body part and the pair of lid members, is capable of relative reciprocating motion along the longitudinal direction of the track member. A direction change path (31) formed on the lid members comprises an inner direction change path (31A) and an outer direction change path (31B) that three-dimensionally intersect each other. The lid members are each configured by combining two lid constituent members (51, 61). Among the lid constituent members, when the lid constituent member (61) disposed farther from the installation surface for the movement member body part on the lid member is removed, a part of the portion constituting the outer peripheral side of each of the inner direction change path and the outer direction change path opens to form, for each of the inner direction change path and the outer direction change path, a rolling element insertion opening path (α) into which the plurality of rolling elements can be inserted. With such a configuration, an easy-to-assemble motion guide device can be obtained.

　運動案内装置の一種であるリニアガイドは、例えば、長手方向に沿って複数の転動体転走面が形成される軌道部材としての軌道レールと、複数の転動体転走面のそれぞれに対向する複数の負荷転動体転走面と、複数の負荷転動体転走面が延びる方向と平行に延びる複数の転動体戻り通路と、が形成される移動部材本体部と、移動部材本体部の移動方向の両端に設けられ、負荷転動体転走面と転動体戻り通路とを接続する方向転換路が形成される一対の蓋部材と、転動体転走面と負荷転動体転走面からなる負荷転動体転走路と、転動体戻り通路と、一対の方向転換路と、で形成される無限循環路を転がり運動する複数の転動体と、を備えるものである。そして、移動部材本体部と一対の蓋部材とで形成される移動部材としての移動ブロックが、複数の転動体を介して軌道部材に組み付けられることで、当該移動部材は軌道部材の長手方向に沿って相対的に往復運動自在とされる。 A linear guide, which is a type of motion guide device, includes, for example, a track rail as a track member in which a plurality of rolling element rolling surfaces are formed along the longitudinal direction, and a plurality of track rails that are opposite to each of the plurality of rolling element rolling surfaces. a moving member main body portion formed with a loaded rolling element rolling surface and a plurality of rolling element return passages extending parallel to the direction in which the plurality of loaded rolling element rolling surfaces extend; A pair of lid members provided at both ends and forming a direction change path connecting the loaded rolling element rolling surface and the rolling element return passage, and a loaded rolling element consisting of the rolling element rolling surface and the loaded rolling element rolling surface. It is provided with a plurality of rolling elements that roll and move in an endless circulation path formed by a rolling path, a rolling element return path, and a pair of direction change paths. A moving block as a moving member formed by a moving member body and a pair of lid members is assembled to the track member via a plurality of rolling elements, so that the moving member is moved along the longitudinal direction of the track member. It is said that it is relatively free to reciprocate.
　ところで、従来のリニアガイドには、上記の方向転換路が、蓋部材における移動部材本体部との設置面に近い側に形成される内側方向転換路と、蓋部材における移動部材本体部との設置面に対して内側方向転換路が形成された位置よりも遠い側に形成される外側方向転換路と、によって構成されるとともに、これら内側方向転換路と外側方向転換路とが立体交差するように配置されるものが存在している。そのような構成を備えるリニアガイドが、例えば、下記特許文献１等に開示されている。 By the way, in the conventional linear guide, the above-mentioned direction change path is formed on the side near the installation surface of the moving member body of the lid member, and the installation surface of the moving member body of the lid member. an outer direction change road formed on a side farther from the position where the inner direction change road is formed, and the inner direction change road and the outer direction change road intersect with each other at grade level. There is something to be placed. A linear guide having such a configuration is disclosed in, for example, Patent Document 1 listed below.
国際公開第２００６／０２８０８４号International Publication No. 2006/028084
　しかしながら、上掲した特許文献１に開示されるような従来のリニアガイドには、組立性の面で改善の余地が残されていた。すなわち、２つの方向転換路が立体交差して配置される場合のリニアガイドにおいて、無限循環路内に複数の転動体を配置するには、移動ブロックの両側から一対の蓋部材を取り外して両側から複数の転動体を挿入することが行われていたが、このような従来の製造方法は、多くの組立時間を要するものであった。また、一対の方向転換路はＵ字形状をしたものであるため、そのような形状の箇所に複数の転動体を挿入する場合には、転動体の挿入状態が不安定になり易く、組立時に転動体が落下する危険性が高いために、さらに製造時間を要してしまうといった課題が存在していた。 However, the conventional linear guide as disclosed in Patent Document 1 mentioned above still leaves room for improvement in terms of ease of assembly. In other words, in a linear guide where two direction change paths are arranged to intersect with each other, in order to arrange a plurality of rolling elements in the endless circulation path, a pair of lid members are removed from both sides of the moving block, and a pair of cover members are removed from both sides of the moving block. Although a plurality of rolling elements have been inserted, such conventional manufacturing methods require a lot of assembly time. In addition, since the pair of direction change paths are U-shaped, when multiple rolling elements are inserted into such a shaped part, the inserted state of the rolling elements tends to become unstable, and it is difficult to assemble the parts. Since there is a high risk of the rolling elements falling, there is a problem in that it requires additional manufacturing time.
　本発明は、上述した従来技術に存在する課題に鑑みて成されたものであって、その目的は、組立性に優れた構造を有する運動案内装置を得ることにある。 The present invention has been made in view of the problems existing in the prior art described above, and its purpose is to obtain a motion guide device having a structure that is easy to assemble.

It consists of Further, a sealing member 32 made of, for example, a resin material having sealing properties can be fixedly installed at the end of the lid member 30 in the relative movement direction.
　移動ブロック本体部１７は、軌道レール１１のローラ転走面１５に対応する位置に軌道面となる負荷転動体転走面としての負荷ローラ転走面１９を備えて構成される。軌道レール１１のローラ転走面１５と移動ブロック１３の負荷ローラ転走面１９とによって負荷転動体転走路としての負荷ローラ転走路２１が形成され、当該負荷ローラ転走路２１には、複数のローラ１２が負荷を受けた状態で転がり運動可能なように配置される。また、移動ブロック本体部１７には、負荷ローラ転走路２１に対して平行配置される転動体戻り通路としてのローラ戻り通路２３がその内部に形成される。 The moving block main body 17 is configured to include a loaded roller rolling surface 19 as a loaded rolling element rolling surface serving as a raceway surface at a position corresponding to the roller rolling surface 15 of the track rail 11. The roller rolling surface 15 of the track rail 11 and the loaded roller rolling surface 19 of the moving block 13 form a loaded roller rolling path 21 as a loaded rolling element rolling path, and the loaded roller rolling path 21 includes a plurality of rollers. 12 is arranged so that it can roll under load. Furthermore, a roller return passage 23 as a rolling element return passage arranged parallel to the loaded roller rolling path 21 is formed inside the movable block main body 17 .

Furthermore, there are a total of four roller return passages 23, two on the left and two on the left and right, which connect to the direction change passages 31, which are eight in total on the front side and the back side. As shown in FIG. Two turn paths 31 are arranged as one set in each of the two lanes, and are arranged so as to intersect with each other. In this embodiment, of the pair of direction change paths 31 that intersect with each other, the direction change path 31 formed on the side of the cover member 30 that is closer to the installation surface with the movable block main body 17 is referred to as the inner direction change path 31A.

It is configured to include an inner lid component 51 and an outer lid component 61.
　移動ブロック本体部１７は、図５に示すように、正面視で略門型形状をした部材であり、金属材料等の剛性の高い材料で構成されている。略門型形状の内周側の左右壁面には、それぞれ２つずつ合計４つの負荷ローラ転走面１９が形成されている。上述したように、これら４つの負荷ローラ転走面１９が軌道レール１１に形成された４条のローラ転走面１５と対向して配置されることで、負荷ローラ転走路２１が構成される。 As shown in FIG. 5, the moving block main body portion 17 is a member having a substantially gate-shaped shape when viewed from the front, and is made of a highly rigid material such as a metal material. A total of four loaded roller rolling surfaces 19, two each, are formed on the left and right wall surfaces on the inner peripheral side of the substantially gate-shaped roller. As described above, the loaded roller rolling path 21 is configured by arranging these four loaded roller rolling surfaces 19 to face the four roller rolling surfaces 15 formed on the track rail 11.
　また、移動ブロック本体部１７には、４つの負荷ローラ転走面１９が延びる方向と平行に延びる４つの貫通孔２５が形成されている。これら４つの貫通孔２５には、樹脂部材群４０を構成するパイプ部材４１（詳細は後述する）が挿入設置されることで、ローラ戻り通路２３が形成されることとなる。さらに、移動ブロック１３の移動方向の両端、つまり、正面側と背面側の面には、一対の蓋部材３０を設置するための複数のボルト穴２６が形成されており、図３に示すような移動ブロック本体部１７に対する一対の蓋部材３０の取り付けが可能となっている。 Further, the moving block main body 17 is formed with four through holes 25 that extend parallel to the direction in which the four loaded roller rolling surfaces 19 extend. Pipe members 41 (details will be described later) constituting the resin member group 40 are inserted into these four through holes 25, thereby forming a roller return passage 23. Further, a plurality of bolt holes 26 for installing a pair of lid members 30 are formed on both ends of the moving block 13 in the moving direction, that is, on the front side and the back side, as shown in FIG. A pair of lid members 30 can be attached to the moving block main body 17.
　樹脂部材群４０は、図６に示すように、４本のパイプ部材４１と、４個の方向転換路構成部材４２と、２本のローラ案内部材４３により構成されており、これらの部材が移動ブロック本体部１７に組み付けられることで、ローラ戻り通路２３や方向転換路３１の一部を構成することになる。 As shown in FIG. 6, the resin member group 40 is composed of four pipe members 41, four turning path members 42, and two roller guide members 43, and these members are movable. By being assembled to the block main body 17, it constitutes a part of the roller return path 23 and the direction change path 31.
　パイプ部材４１は、貫通孔２５に挿入して設置されることでローラ戻り通路２３を形成する部材であり、図８等で示すように、その外観形状は円筒管形状をしたパイプ状の部材となっている。パイプ部材４１の外周面は貫通孔２５の内周面に沿った形状を含んでおり、移動ブロック１３の移動方向に沿って挿し込むことで、容易に設置することが可能となっている。一方、パイプ部材４１の内周面は、図８中の分図（ｂ）においてより詳細に示されるように、複数のローラ１２が連なった状態で転がり運動できるように、ローラ１２の外観形状に沿った孔形状を有しており、この孔形状がローラ戻り通路２３を形成している。さらに、パイプ部材４１の両端部には、第１の凸形状部４１ａが形成されており、後述する方向転換路構成部材４２と内側蓋構成部材５１を組み付けた際に、ローラ１２を保持するための本実施形態の保持形状部として機能する。 The pipe member 41 is a member that forms the roller return passage 23 by being inserted into the through hole 25 and installed, and as shown in FIG. It has become. The outer peripheral surface of the pipe member 41 includes a shape that follows the inner peripheral surface of the through hole 25, and can be easily installed by being inserted along the moving direction of the moving block 13. On the other hand, the inner circumferential surface of the pipe member 41 is shaped into the external shape of the rollers 12 so that a plurality of rollers 12 can roll and move in a row, as shown in more detail in FIG. This hole shape forms a roller return passage 23. Furthermore, first convex portions 41a are formed at both ends of the pipe member 41, and are used to hold the roller 12 when the direction change path component 42 and the inner lid component 51, which will be described later, are assembled. It functions as the holding shape part of this embodiment.
　方向転換路構成部材４２は、２本のパイプ部材４１の両端部をつなげるように設置される部材である。図６中の分図（ａ）に示されるように、方向転換路構成部材４２を正面視で見たとき、右上と左下に配置される２本のパイプ部材４１は、内側方向転換路３１Ａにつながるローラ戻り通路２３Ａを形成しており、右下と左上に配置される２本のパイプ部材４１は、外側方向転換路３１Ｂにつながるローラ戻り通路２３Ｂを形成している。そして、これら２本のパイプ部材４１と接続する方向転換路構成部材４２は、移動ブロック本体部１７と蓋部材３０の間に組み込まれることで、内側方向転換路３１Ａの内周側３１Ａ１と内側方向転換路３１Ａの外周側３１Ａ２の一部を構成するとともに、外側方向転換路３１Ｂの内周側３１Ｂ１を構成する。つまり、本実施形態の方向転換路構成部材４２は、内側方向転換路３１Ａの内周側３１Ａ１および内側方向転換路３１Ａの外周側３１Ａ２の一部と、外側方向転換路３１Ｂの内周側３１Ｂ１が立体交差するように構成する部材である（図６～図８参照）。 The direction change path component 42 is a member installed so as to connect both ends of the two pipe members 41. As shown in the partial view (a) in FIG. 6, when the direction change path component 42 is viewed from the front, the two pipe members 41 arranged at the upper right and lower left are connected to the inner direction change path 31A. The two pipe members 41 arranged at the lower right and upper left form a roller return passage 23B that connects to the outer direction change path 31B. The direction change path forming member 42 connected to these two pipe members 41 is incorporated between the moving block main body 17 and the lid member 30, so that the direction change path constituting member 42 connects to the inner peripheral side 31A 1 of the inner direction change path 31A. It constitutes a part of the outer peripheral side 31A 2 of the direction change path 31A, and also constitutes the inner peripheral side 31B 1 of the outer direction change path 31B. In other words, the turning path component 42 of this embodiment includes the inner circumferential side 31A 1 of the inner turning path 31A, a part of the outer circumferential side 31A 2 of the inner turning path 31A, and the inner circumferential side of the outer turning path 31B. 31B 1 is a member configured to intersect three-dimensionally (see FIGS. 6 to 8).
　ローラ案内部材４３は、２本のパイプ部材４１の両端部に設置される正面側の方向転換路構成部材４２と背面側の方向転換路構成部材４２をつなげるように、２本のパイプ部材４１に対して平行に配置される部材である。このローラ案内部材４３は、複数のローラ１２が移動ブロック１３に形成された負荷ローラ転走面１９を転走するときに、複数のローラ１２を案内して支承する部材である。ローラ案内部材４３が設置されることで、移動ブロック１３を軌道レール１１から取り外した際に、移動ブロック１３から複数のローラ１２が脱落することを防止することができる。 The roller guide member 43 is attached to the two pipe members 41 so as to connect the front side turning path forming member 42 and the back side turning path forming member 42 installed at both ends of the two pipe members 41. This is a member arranged parallel to the other. The roller guide member 43 is a member that guides and supports the plurality of rollers 12 when the plurality of rollers 12 roll on the loaded roller rolling surface 19 formed on the moving block 13. By installing the roller guide member 43, it is possible to prevent the plurality of rollers 12 from falling off from the moving block 13 when the moving block 13 is removed from the track rail 11.
　以上説明した樹脂部材群４０を移動ブロック本体部１７に対して組み込んだ状態が、図１１に示されている。図１１で示した状態の移動ブロック本体部１７の移動方向の両端部に対して、一対の蓋部材３０を取り付けることで移動ブロック１３が完成するが、本実施形態の蓋部材３０は、図４等で示すように、内側蓋構成部材５１と外側蓋構成部材６１とで構成されている。 FIG. 11 shows a state in which the resin member group 40 described above is assembled into the moving block main body 17. The moving block 13 is completed by attaching a pair of lid members 30 to both ends in the moving direction of the moving block main body 17 in the state shown in FIG. As shown, it is composed of an inner lid component 51 and an outer lid component 61.
　図９で示される内側蓋構成部材５１は、方向転換路構成部材４２を含む樹脂部材群４０を組み込んだ状態の移動ブロック本体部１７に設置される部材であり、内側方向転換路３１Ａの外周側３１Ａ２の一部と外側方向転換路３１Ｂの外周側３１Ｂ２の一部を構成する部材である。内側蓋構成部材５１を移動ブロック本体部１７に設置した状態が、図１２に示されている。 The inner cover component 51 shown in FIG. 9 is a member installed in the moving block main body 17 in which the resin member group 40 including the direction change path component 42 is installed, and is located on the outer peripheral side of the inner direction change path 31A. 31A2 and a part of the outer peripheral side 31B2 of the outer direction change path 31B. FIG. 12 shows a state in which the inner lid component 51 is installed on the movable block main body 17.
　また、本実施形態の内側蓋構成部材５１には、図９中の分図（ａ）の右下の箇所に示すように、第２の凸形状部５１ａが形成されている。この第２の凸形状部５１ａは、上述したパイプ部材４１の両端部に形成された第１の凸形状部４１ａと同様に、移動ブロック本体部１７に対して方向転換路構成部材４２と内側蓋構成部材５１を組み付けた際に、ローラ１２を保持するための本実施形態の保持形状部として機能する部位である。なお、本実施形態に係る移動ブロック１３の製造方法は後述するが、本実施形態の内側蓋構成部材５１は、無限循環路に複数のローラ１２を挿入する際に、無限循環路（特に、方向転換路３１）からローラ１２が脱落しないように機能することで、組立性の向上に寄与することができる。 Further, the inner lid component 51 of this embodiment is formed with a second convex portion 51a, as shown at the lower right portion of the partial view (a) in FIG. This second convex portion 51a, similar to the first convex portion 41a formed at both ends of the pipe member 41 described above, is connected to the turning path forming member 42 and the inner cover with respect to the moving block main body portion 17. This is a portion that functions as a holding shaped portion in this embodiment for holding the roller 12 when the component 51 is assembled. Although a method for manufacturing the moving block 13 according to the present embodiment will be described later, the inner lid component 51 of the present embodiment is suitable for inserting a plurality of rollers 12 into the endless circulation path (especially in the direction). By functioning to prevent the roller 12 from falling off from the diversion path 31), it is possible to contribute to improving assembly efficiency.
　一方、図１０で示される外側蓋構成部材６１は、内側蓋構成部材５１の外側に設置される部材である。外側蓋構成部材６１は、内側方向転換路３１Ａの外周側３１Ａ２の一部と外側方向転換路３１Ｂの外周側３１Ｂ２の一部を有しており、内側蓋構成部材５１を組み込むようにして移動ブロック本体部１７に設置することで、蓋部材３０と移動ブロック１３を構成することになる。外側蓋構成部材６１の設置によって、蓋部材３０と方向転換路構成部材４２とが協働してＵ字形状をした方向転換路３１が形成される。 On the other hand, the outer lid component 61 shown in FIG. 10 is a member installed outside the inner lid component 51. The outer lid component 61 has a part of the outer peripheral side 31A 2 of the inner direction change path 31A and a part of the outer peripheral side 31B 2 of the outer direction change path 31B, and incorporates the inner lid component 51. By installing it on the movable block main body 17, the cover member 30 and the movable block 13 are configured. By installing the outer lid component 61, the lid member 30 and the direction change path component 42 cooperate to form a U-shaped direction change path 31.
　以上、本実施形態のリニアガイド１０を構成する部材のうち、特に、移動ブロック１３の具体的な構成を詳細に説明した。次に、本実施形態の移動ブロック１３の製造方法についての説明を行う。 Above, among the members constituting the linear guide 10 of this embodiment, the specific configuration of the moving block 13 has been described in detail. Next, a method for manufacturing the moving block 13 of this embodiment will be explained.
　まず、図５で示す移動ブロック本体部１７に対して、図６で示される樹脂部材群４０を組み付けることで、図１１で示す状態とする。なお、移動ブロック本体部１７に対する樹脂部材群４０の組み付け手順としては、例えば、４つの貫通孔２５のそれぞれに樹脂部材群４０を構成するパイプ部材４１を挿入設置し、その後にパイプ部材４１の両端部に方向転換路構成部材４２を組み付けるようにしてもよいし、もしくは、あらかじめパイプ部材４１の一方側（例えば、正面側）の端部に方向転換路構成部材４２を組み付けておき、この状態のパイプ部材４１を貫通孔２５に挿入した後で、パイプ部材４１の他方側（例えば、背面側）の端部に方向転換路構成部材４２を組み付けることで、図１１で示す状態としてもよい。 First, the resin member group 40 shown in FIG. 6 is assembled to the movable block main body 17 shown in FIG. 5 to create the state shown in FIG. 11. The procedure for assembling the resin member group 40 to the moving block main body 17 is, for example, by inserting and installing the pipe members 41 constituting the resin member group 40 into each of the four through holes 25, and then inserting and installing the pipe members 41 constituting the resin member group 40 into each of the four through holes 25. Alternatively, the direction change path component 42 may be assembled in advance on one end (for example, the front side) of the pipe member 41, and the After the pipe member 41 is inserted into the through hole 25, the direction change path forming member 42 may be assembled to the end of the other side (for example, the back side) of the pipe member 41, thereby creating the state shown in FIG. 11.
　続いて、方向転換路構成部材４２を覆うように内側蓋構成部材５１を移動ブロック本体部１７に設置する。なお、方向転換路構成部材４２は、移動ブロック本体部１７の移動方向の端部の両側に対して設置する。この段階の設置状態が、図１２に示されている。 Subsequently, the inner lid component 51 is installed on the moving block main body 17 so as to cover the direction change path component 42. Note that the turning path constituent members 42 are installed on both sides of the end portion of the moving block main body portion 17 in the moving direction. The installation state at this stage is shown in FIG.
　そして、図１２で示す状態の移動ブロック本体部１７の一方側のみに、外側蓋構成部材６１を設置する。この状態から、移動ブロック本体部１７の移動方向が鉛直方向を向くように当該移動ブロック本体部１７を配置するとともに、外側蓋構成部材６１を設置した側が底面側となるようにする。かかる状態が、図１３に示されている。 Then, the outer lid component 61 is installed only on one side of the moving block main body 17 in the state shown in FIG. 12. From this state, the movable block main body 17 is arranged so that the moving direction of the movable block main body 17 faces the vertical direction, and the side on which the outer lid component 61 is installed is the bottom side. Such a state is shown in FIG.
　図１３で示すように、２つの蓋構成部材５１，６１のうち、蓋部材３０における移動ブロック本体部１７との設置面から遠い側に配置される外側蓋構成部材６１のうちの１つを取り外した状態のとき、内側方向転換路３１Ａと外側方向転換路３１Ｂそれぞれの外周側３１Ａ２，３１Ｂ２を構成する部位の一部が取り除かれることになるので、当該部位が開口することとなり、内側方向転換路３１Ａと外側方向転換路３１Ｂそれぞれに対して複数のローラ１２を挿入可能な本実施形態の転動体挿入開口経路としてのローラ挿入開口経路αが形成されることとなる。 As shown in FIG. 13, of the two lid components 51 and 61, one of the outer lid components 61 disposed on the side far from the installation surface with the movable block main body 17 of the lid member 30 is removed. In this state, a part of the portion forming the outer circumferential sides 31A 2 and 31B 2 of the inner direction change path 31A and the outer direction change path 31B is removed, so this portion is opened and the inner direction change path 31A and the outer direction change path 31B are removed. A roller insertion opening path α is formed as a rolling element insertion opening path of this embodiment into which a plurality of rollers 12 can be inserted into each of the switching path 31A and the outer direction switching path 31B.
　また、図１４には、ローラ挿入開口経路αを通じて複数のローラ１２が無限循環路内に設置された状態が示されているが、このとき、内側蓋構成部材５１の外郭形状と、内側蓋構成部材５１に形成された保持形状部としての第２の凸形状部５１ａと、パイプ部材４１に形成された保持形状部としての第１の凸形状部４１ａとの作用によって、複数のローラ１２が無限循環路内から落下しない状態が維持できることとなる。 Further, FIG. 14 shows a state in which a plurality of rollers 12 are installed in the endless circulation path through the roller insertion opening path α. At this time, the outer shape of the inner lid component 51 and the inner lid structure Due to the action of the second convex portion 51a as a holding portion formed on the member 51 and the first convex portion 41a as a holding portion formed on the pipe member 41, the plurality of rollers 12 are moved infinitely. This makes it possible to maintain a state in which the product does not fall from within the circulation path.
　最後に、図１４に示された状態から、正面側の外側蓋構成部材６１を取り付けることで、本実施形態に係る移動ブロック１３が完成し、完成した移動ブロック１３を軌道レール１１に組み付けることで、本実施形態のリニアガイド１０が完成する。 Finally, the moving block 13 according to the present embodiment is completed by attaching the outer lid component 61 on the front side from the state shown in FIG. , the linear guide 10 of this embodiment is completed.
　以上説明したように、本実施形態に係る移動ブロック１３は、組立時にローラ１２が落下する危険性が非常に低い構造を有しているので、従来技術に比べて製造時間を短縮することができる。また、本実施形態に係る移動ブロック１３は、２つの方向転換路３１（３１Ａ，３１Ｂ）が立体交差して配置される構成を有しながらも、製造が容易にできる構成を有しているので、本実施形態によれば、組立性に優れた構造を有するリニアガイド１０を提供することができる。 As explained above, the moving block 13 according to the present embodiment has a structure in which the risk of the roller 12 falling during assembly is extremely low, so that the manufacturing time can be shortened compared to the conventional technology. . Further, the moving block 13 according to the present embodiment has a configuration in which the two direction change paths 31 (31A, 31B) are arranged in a three-dimensional intersection, but has a configuration that can be easily manufactured. According to this embodiment, it is possible to provide a linear guide 10 having a structure with excellent assemblability.
