  However, in the conventional linear guide device as described above, when the rolling element collides with the lubrication member arranged in the direction change path of the end cap, the lubrication member is broken and the fragments are located between the direction change path and the rolling element. Get in. Thereby, the surface of the direction change path is plastically deformed and rises, and each time the rolling element passes through the raised portion, the rolling element and the direction change path repeatedly receive a load.

Here, the length of the cylindrical portion 19 of the lubricant container 7 and the protruding portion 43 of the lubricating member 40 in the longitudinal direction of the slider body 4, that is, the left-right direction in FIG. 5 is designed so that no step is formed between the five direction change paths 5a and the rolling grooves. And the front end surface of the cylindrical part 19 of the lubricant container 7 and the front end surface of the protrusion part 43 of the lubricating member 40 are curved shapes along the rolling groove of the direction change path 5a of the end cap 5 as shown in FIG. 6B. Each is processed.

Hereinafter, the assembly procedure of the slider 31 in the present embodiment will be described with reference to FIG.
The lubricant container 7 is previously sealed by inserting the lubricating member 40 into each recess 18 and attaching the lid 22 from the back side.

  Procedure 1: As shown in FIG. 9A, the end caps 5 are arranged at both ends in the longitudinal direction of the slider body 4 so that the surfaces on which the direction changing paths 5a are formed, that is, the front faces. Then, the screw 24 is fixed to the screw hole 11 of the slider body 4 through the through hole 13 of the end cap 5. The through hole 13 and the screw hole 11 are not shown in FIG. Thereby, the attachment of the end cap 5 to the slider body 4 is achieved.

  Procedure 2: As shown in FIG. 9B, the lubricant container 7 is attached to each end cap 5 from the outside in the longitudinal direction of the slider body 4 with the surface on which the cylindrical portion 19 is formed, that is, the front surface facing. The cylindrical portion 19 is not shown in FIG. At this time, the cylindrical portion 19 of the lubricant container 7 is inserted into each through hole 16 of the end cap 5. Thereby, positioning of the lubricant container 7 with respect to the end cap 5 is achieved.

  Procedure 3: As shown in FIG. 9C, side seals 8 are arranged on the lubricant containers 7 from the outside in the longitudinal direction of the slider body 4. Then, the screw 26 is passed through the through hole 9 of the side seal 8, the through hole 23 of the lid 22 of the lubricant container 7, the through hole 20 of the lubricant container 7, and the through hole 14 of the end cap 5 in order. Fix to the screw hole 12. The through holes 9 and 20 and the screw hole 12 are not shown in FIG. Thereby, attachment of the lubricant container 7 and the side seal 8 to the slider body 4 is achieved.

  The slider 31 can be easily assembled by the above assembly procedure. In particular, in the procedure 2, the lubricant container 7 can be positioned with respect to the end cap 5 by inserting the cylindrical portions 19 of the lubricant container 7 into the four through holes 16 of the end cap 5 as described above. it can. For this reason, in the procedure 3, the lubricant container 7 can be easily fixed to the slider body 4 together with the side seal 8 with the common screw 26. Further, since the lubricant members 40 are respectively held in the four recesses 18 of the lubricant container 7 as described above, the four lubricant members 40 can be handled by the lubricant container 7 at a time. For this reason, not only the assembly of the slider 31 is facilitated, but also the maintenance of the slider 31 is facilitated. Further, since the lubricating members 40 can be handled individually, the slider 31 can be supplied with oil evenly.

In the slider 31 assembled based on the above assembly procedure, the tip of the cylindrical portion 19 of the lubricant container 7 and the tip of the protrusion 43 of the lubricant member 40 are connected to the direction change path 5a of the end cap 5 as shown in FIG. The through hole 16 is exposed inside, and a curved surface is formed in the through hole 16 along the rolling groove of the direction changing path 5a. More specifically, the distal end surface of the cylindrical portion 19 of the lubricant container 7 and the distal end surface of the protrusion 43 of the lubricating member 40 form a single curved surface together with the rolling groove of the direction changing path 5a.
With this configuration, when the slider 31 is linearly moved on the guide rail 2, the rolling element that rolls on the direction change path 5 a comes into contact with the tip surface of the protrusion 43 of the lubricating member 40 and is applied with lubricant. Thus, oil can be supplied into the slider 31.

  Further, as described above, the tip of the cylindrical portion 19 of the lubricant container 7 and the tip of the protrusion 43 of the lubricant member 40 form a curved surface along the rolling groove of the direction change path 5a, so that A moving body can roll smoothly in the direction change path 5a. Therefore, unlike the prior art, the rolling element does not collide with the lubricating member 40, the lubricating member 40 is broken, and the fragments do not enter the direction change path 5a and the rolling element as foreign matter. . Further, unlike the prior art, there is a step between the direction change path 5a and the lubricating member 40, and there is no possibility that the rolling element collides with the step and runs around. Accordingly, it is possible to prevent the rolling element and the direction change path 5a from being damaged, and it is possible to prevent the slider 31 from being broken or malfunctioning.

  Further, as described above, the lubricating member 40 includes the second lubricating member 42 made of a porous molded body and the first lubricating member 41 made of a porous molded body having a higher density than the second lubricating member 42. Yes. For this reason, the amount per unit volume of the first lubricating member 41 that can hold the lubricant is smaller than that of the second lubricating member 42. With such a configuration, the second lubricating member 42 can function as a holding portion that holds the lubricant. The first lubricating member 41 applies an appropriate amount of lubricant to the rolling elements while preventing the lubricant held by the second lubricating member 42 from flowing into the direction change path 5a of the end cap 5. It can function as an application part. Therefore, a large amount of lubricant can be prevented from being consumed in a short period of time, and refueling can be performed stably for a long period of time.

  In addition, the material of the 1st, 2nd lubricating members 41 and 42 is not restricted to the porous molded body from which the density differs as mentioned above. The amount per unit volume that the first lubricating member 41 can hold the lubricant may be smaller than that of the second lubricating member 42, and the first and second lubricating members 41 and 42 may be made of different materials. Alternatively, the first lubricating member 41 may be formed of a porous molded body, and the second lubricating member 42 may be configured to fill the concave portion 18 of the lubricant container 7 with a lubricant such as grease or lubricating oil.

The oil supply device for a linear guide device according to this embodiment includes an end cap 5, a lubricant container 70, and a lubricant member 400.

In the lubricant container 70 in the present embodiment, instead of the cylindrical portion 19 of the lubricant container 7 in the first embodiment, as shown in FIG. 11A and FIG. Circular openings 25 having the same diameter as the through holes 16 are formed at positions facing the four through holes 16 of the cap 5.
As shown in FIG. 13A, the lubricating member 400 held in the concave portion 18 of the lubricant container 70 replaces the protrusion 43 of the lubricant member 40 in the first embodiment, ie, the inner side in the longitudinal direction of the slider 30, that is, FIG. A protrusion 430 that extends to the right of 13 </ b> A and protrudes outward from the circular opening 25 of the lubricant container 70 is formed integrally with the first lubricating member 410. As shown in FIG. 13B, the protrusion 430 has a cylindrical shape that fits into the circular opening 25 of the lubricant container 70 and the through hole 16 of the end cap 5.

With the above configuration, when the lubricant container 70 holding the lubricating member 400 is attached to the end cap 5, as shown in FIG. 13B, the protruding portion of the lubricating member 400 is formed in the through hole 16 of the direction changing path 5a of the end cap 5. 430 can be fitted. And the protrusion part 430 of the lubricating member 400 can be exposed in the direction change path 5a.
Here, the length of the protrusion 430 of the lubricating member 400 in the longitudinal direction of the slider body 4, that is, the left-right direction in FIG. 13B, is between the protrusion 430 and the rolling groove of the direction changing path 5 a of the end cap 5. It is designed so that there is no step. And the front end surface of the projection part 430 of the lubricating member 400 is processed into the curved surface shape along the rolling groove of the direction change path 5a of the end cap 5, as shown to FIG. 13B.

Hereinafter, the assembly procedure of the slider 32 in this embodiment will be described with reference to FIG.
The lubricant container 70 is sealed in advance by inserting the lubricating member 400 into each recess 18 and attaching the lid 22 from the back side.
Procedure 1: The procedure is the same as the procedure 1 of the assembling procedure of the slider 31 in the first embodiment. See FIG. 14A.

Procedure 2: As shown in FIG. 14B, the lubricant container 70 is attached to each end cap 5 from the outside in the longitudinal direction of the slider body 4 with the surface where the circular opening 25 is formed, that is, the front facing. The circular opening 25 is not shown in FIG. At this time, the protrusions 430 of the lubricating member 400 are inserted into the through holes 16 of the end cap 5. Thereby, the positioning of the lubricant container 70 with respect to the end cap 5 is achieved.

Thereby, the positioning of the lubricant container 71 with respect to the end cap 5 is achieved.
Procedure 3: The procedure is the same as the procedure 3 of the assembling procedure of the slider 32 in the second embodiment. See Figure 18C.

  By the above assembling procedure, the slider 33 can be easily assembled, and the same effect as the second embodiment can be obtained. In particular, in this embodiment, in step 2, the lubricant container 71 is positioned with respect to the end cap 5 using the protrusion 71b of the lubricant container 71 harder than the protrusion in addition to the protrusion of the lubricant member 401. For this reason, it is possible to effectively prevent the lubricant container 71 from being displaced relative to the end cap 5 after positioning. Further, the protrusion 71 b is provided in a central position of the body portion 71 a of the lubricant container 71. For this reason, in the procedure 2, the protrusion 71b can be easily fitted in the recess 5c of the end cap 5, and the positioning of the lubricant container 71 with respect to the end cap 5 can be performed more easily.

  The slider 33 assembled based on the above assembly procedure can achieve the same effects as those of the second embodiment. In particular, the concave portion 180 of the lubricant container 71 in the present embodiment extends in an L shape from the leg portion of the lubricant container 71 to the center position of the trunk portion 71a, and therefore, compared with the first and second embodiments. Thus, the large lubricating member 401 holding a large amount of lubricant can be held. For this reason, refueling can be performed stably for a longer period of time, and the life of the slider 33 can be extended.

In addition, it is possible to reduce a deviation in the amount of oil supply for each direction change path 5a.

(Fifth embodiment)
About the linear guide apparatus 105 provided with the oil supply apparatus for linear guide apparatuses concerning 5th Embodiment shown in FIG. 24, about the structure similar to the said 3rd Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted, About different structure This will be described in detail.
The oil supply device for a linear guide device according to this embodiment includes an end cap 5, a lubricant container 73, and a lubricant member 401.

  As shown in FIGS. 25 and 26, the lubricant container 73 in the present embodiment is a front surface of the lubricant container 73, that is, a surface on the inner side in the longitudinal direction of the slider 35, and is circular at a position facing each circular opening 25. Recesses 73a are respectively provided. The circular recess 73 a is a recess for fitting an O-ring 45 described later, and is concentric with the circular opening 25 and larger in diameter than the circular opening 25.

Hereinafter, the assembly procedure of the slider 35 in the present embodiment will be described with reference to FIG.
The lubricant container 73 is previously sealed by inserting the lubricant member 401 into each recess 180 and attaching the lid 220 from the back side.
Procedure 1: Same as Procedure 1 of the assembly procedure of the slider 33 in the third embodiment. See Figure 28A.

For this reason, it is possible to prevent the lubricant from leaking from between the lubricant container 73 and the end cap 5 to the outside of the slider 35. Accordingly, it is possible to prevent the periphery of the slider 35 from being contaminated with the lubricant and to prevent unnecessary consumption of the lubricant.

(Sixth embodiment)
About the linear guide apparatus 106 provided with the oil supply apparatus for linear guide apparatuses which concerns on 6th Embodiment shown in FIG. 29, about the structure similar to the said 3rd Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted, About different structure This will be described in detail.
The oil supply device for a linear guide device according to this embodiment includes an end cap 5, a lubricant container 74, and a lubricant member 401.

  As shown in FIG. 30, the lubricant container 74 in the present embodiment is obtained by removing the lip portions 7 a of the leg portions on both sides in the lubricant container 71 in the third embodiment. That is, the inner side surfaces 74a of the leg portions on both sides of the lubricant container 74 are flat surfaces without any unevenness. With this configuration, the lubricant container 74 can be inserted and straddled with respect to the guide rail 2 from the upper surface side of the guide rail 2.

  Under the above configuration, the slider 36 in the present embodiment can be easily assembled by the same assembling procedure as in the third embodiment, and the same effect as in the third embodiment can be obtained. See FIGS. 31A-31C. In particular, in this embodiment, since the lubricant container 74 does not have the lip portion on the inner side surfaces 74a of the leg portions on both sides as described above, it can be inserted into and removed from the guide rail 2 from the upper surface side. Therefore, when the slider 36 is maintained, only the lubricant container 74 can be removed from the guide rail 2 and the lubricant member 401 can be easily replaced, and can be fitted over the guide rail 2 again.

  Moreover, in each said embodiment, it is the structure which hold | maintains the lubricating members 40 and 400-402 which consist of the porous molded object which impregnated the lubricant in each recessed part 18 and 180 of the lubricant containers 7 and 70-74. However, the present invention is not limited to this, and a configuration may be adopted in which lubricants such as grease and lubricating oil are held in the recesses 18 and 180 of the lubricant containers 7 and 70 to 74. For example, in the first embodiment, the lubricant may be filled in the space formed by the concave portion 18 and the cylindrical portion 19 of the lubricant container 7. Moreover, in 2nd Embodiment, it is good also as a structure filled with a lubricant in the space formed by the recessed part 18, the circular opening 25 of the lubricant container 70, and the through-hole 16 of the direction change path 5a in the end cap 5. FIG.

  Moreover, in each said embodiment, although the porous molded body which impregnated the lubricant is used as the lubricating members 40 and 400-402, it is not restricted to this, The porous which can be elastically deformed as the lubricating members 40, 400-402 A molded body (hereinafter referred to as “porous elastic body”) impregnated with a lubricant can also be used. Thereby, when the rolling element which drive | works the direction change path 5a contacts the lubricating members 40 and 400-402, the lubricating members 40 and 400-402 can elastically deform. For this reason, it is possible to prevent the lubrication members 40 and 400 to 402 from being worn out and dropped into the direction changing path 5a, and to prevent the operability of the sliders 31 to 36 from being deteriorated and the life from being shortened.

  In each of the above embodiments, a synthetic resin, specifically, polyethylene (PE), polypropylene (PP), polyamide (PA), or polyacetal (POM) having high chemical resistance is used as the material for the lubricant containers 7 and 70 to 74. It is preferable. The end caps 5 and 50 are preferably made of elastic POM as a material so as to be easily attached to the slider body 4. For this reason, the lubricant containers 7 and 70 to 74 are also easily attached to the end caps 5 and 50, and the minute vibrations that are intermittently generated when the sliders 31 to 36 pass through the joint between the guide rail 2 and the guide rail 2. It is particularly preferable to use POM as a material so that it can be absorbed.

Moreover, in each said embodiment, it is preferable to use polymer materials, especially polyolefin, such as a polypropylene and polyethylene, as the material of the lubricating members 40 and 400-402.
Polyolefin has a specific gravity of 1 or less and is lightweight. Therefore, the load applied to the lubricant containers 7 and 70 to 74 from the lubrication members 40 and 400 to 402 is reduced by configuring the lubricant members 40 and 400 to 402 with polyolefin. It is effective against this.
Polyolefin has high insulation. Therefore, even when static electricity is generated due to friction between the direction change path 5a of the end caps 5 and 50 and the rolling elements when the sliders 31 to 36 travel on the guide rail 2, the lubricating members 40 and 400 to 402 made of polyolefin are used. Can be insulated. For this reason, it is possible to prevent the lubricant containers 7 and 70 to 74 from being damaged by static electricity.

As shown in FIG. 6B, in the first embodiment, the cylindrical portion 19 of the lubricant container 7 exposed to the direction changing path 5a of the end cap 5 and the protrusion 43 of the lubricating member 40 are connected to the direction changing path 5a. It is flush with the groove. For this reason, even if the rolling element collides, the projection part 43 of the lubricating member 40 is not destroyed. Since the POM has elasticity as described above, if the lubricating member 40 is made of POM, such an effect can be maximized and the lubricating member 40 can be well protected. This also applies to the above-described embodiments other than the first embodiment.
6B, when the cylindrical portion 19 of the lubricant container 7 and the protrusion 43 of the lubricating member 40 are fitted to each other, by using PE that is soft as the material of the lubricating member 40, This is preferable because the protrusion 43 can be easily fitted to the cylindrical portion 19. In order to give the PE rigidity, it is more preferable to compound PP with PE.

  Moreover, animal hair such as wool, aramid, glass, cellulose, nylon, polyester, polyether, polyolefin, rayon and the like can be used as other materials for the lubricating members 40 and 400 to 402. The lubricating members 40 and 400 to 402 can also be used as felt.

(Seventh embodiment)
About the linear guide apparatus 107 provided with the oil supply apparatus for linear guide apparatuses based on 7th Embodiment shown in FIG. 32, about the structure similar to the said 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted, About different structure This will be described in detail.
As shown in FIG. 33A, the oil supply device for a linear guide device according to this embodiment includes an end cap 5, a lubricant container 7, and a lubricating member 151.

  As shown in FIG. 33A, the lubricating member 151 in the present embodiment is formed integrally with the thick plate portion 151a and the thick plate portion 151a that are fitted to the bottom surface of the concave portion 18 of the lubricant container 7. It consists of a protrusion 211 that fits into the hollow part of the cylindrical part 19 of the container 7. The thick plate portion 151a and the protruding portion 211 are made of a porous elastic body impregnated with a lubricant. The length and shape of the protrusion 211 are the same as those of the protrusion 43 of the lubricating member 40 in the first embodiment.

  As shown in FIG. 33A, the lubricating member 151 is inserted into the concave portion 18 of the lubricant container 7, and then the holding member 51 is further inserted to fix the position in the concave portion 18. As shown in FIG. 34, the holding part 51 is a substantially square cylindrical member that is fitted into the side wall of the recess 18 and is made of a porous molded body. The concave portion 18 into which the lubricating member 151 and the pressing member 51 are inserted is filled with the lubricant 49 without any gap, and the lid 22 is attached from the back side of the lubricant container 7 and sealed. The material of the holding part 51 is not limited to the porous molded body.

  With the above configuration, the linear guide device 107 according to the present embodiment can easily assemble the slider 37 by the same assembly procedure as that of the first embodiment, and can achieve the same effects as those of the first embodiment. it can. See Figures 35A-35C.

  As described above, the lubricating member 151 is made of a porous elastic body. For this reason, as shown in FIG. 33A, when the rolling element 52 traveling on the direction change path 5 a comes into contact with the tip surface of the protrusion 211 of the lubricating member 151 and the tip surface receives a force from the rolling element 52, lubrication is performed. The member 151 can be elastically deformed as shown in FIG. 33B. Specifically, the thick plate portion 151 a of the lubricant member 151 is bent outward in the longitudinal direction of the slider 37, that is, leftward in FIG. 33B, and the projection 211 is pushed into the cylindrical portion 19 of the lubricant container 7. At this time, since the position of the lubricating member 151 is fixed by the pressing component 51 in the concave portion 18 of the lubricant container 7, no positional deviation occurs. With such a configuration, it is possible to prevent the lubrication member 151, in particular, the protrusion 211 from being worn and damaged, and to fall into the direction changing path 5a, and effectively prevent the deterioration of the operability and the life of the slider 37. can do. Note that after the rolling element 52 traveling on the direction change path 5a passes through the tip surface of the protrusion 211 of the lubricating member 151, the lubricating member 151 is restored to its original shape as shown in FIG. 33C.

  Further, as described above, the holding part 51 is made of a porous molded body. For this reason, even when the lubricant 49 in the concave portion 18 of the lubricant container 7 decreases with the oil supply to the slider 37 and the lubricant 49 and the lubricant member 151 cannot be in direct contact with each other, the posture of the slider 37 is affected. The lubricant 49 can be guided to the lubricating member 151 via the holding part 51. For this reason, oil supply to the slider 37 can be continued for a longer period of time until the lubricant 49 in the recess 18 runs out.

In addition, the lubricating member 151, the pressing component 51, and the lubricant 49 in the present embodiment can also be applied to the linear guide device 102 in the second embodiment. See FIGS. 36A-36C.
In the present embodiment, the lubricant 49 and the pressing part 51 are inserted into the recess 18 of the lubricant container 7 and then the lubricant 49 is filled without any gap. However, the present invention is not limited to this, and instead of the lubricant 49, a porous molded body impregnated with a lubricant or a porous elastic body impregnated with a lubricant may be arranged in the recess 18 without any gap. This also applies to an eighth embodiment described later.

  As shown in FIG. 38A, the lubricating member 152 in the present embodiment extends to the thick plate portion 152a fitted to the bottom surface of the concave portion 18 of the lubricant container 70 and the slider 32 in the longitudinal direction, that is, to the right in FIG. 38A. And a projection 212 protruding outward from the circular opening 25 of the lubricant container 70. The thick plate portion 152a is made of a porous elastic body impregnated with a lubricant, and the protrusion 212 is made of a porous elastic body having a smaller porosity than the thick plate portion 152a. The length and shape of the protrusion 212 are the same as those of the protrusion 430 of the lubricating member 400 in the second embodiment.

  As shown in FIGS. 52A, 53 and 55B, the end cap 55 is provided with a large-diameter portion 46 at the end of each through-hole 164 on the direction changing path 5a side in the end cap 54 of the tenth embodiment. Is. The large diameter portion 46 is a circular recess for accommodating a tube 47 described later, and is concentric with the through hole 164 and larger in diameter than the through hole 164.

  As shown in FIG. 52, the lubricating member 155 has a cylindrical shape that can be fitted into the circular opening 254 of the lubricant container 75 and the through hole 164 of the end cap 55, and is made of a porous molded body impregnated with the lubricant. Become. The lubricating member 155 is designed to have a length that extends from the bottom surface of the concave portion 18 of the lubricant container 75 to the inside of the large diameter portion 46 of the end cap 55.

  A cylindrical tube 47 is fitted on the tip of the lubricating member 155 as shown in FIGS. 52 and 55B. The tube 47 is made of a polymer material that can be impregnated with a lubricant and elastically deformed in the same manner as the porous molded body constituting the lubricating member 155. The tip of the tube 47 is processed into a shape along the rolling groove of the direction changing path 5 a of the end cap 55. The length of the tube 47 is designed to be slightly longer than the length of the large diameter portion 46 of the end cap 55. In the present embodiment, the tube 47 having such a configuration functions as an application unit that applies the lubricant 49 held by the lubricating member 75 to the rolling elements traveling on the direction change path 5 a of the end cap 55.

Hereinafter, the assembly procedure of the slider 48 in the present embodiment will be described with reference to FIGS. 55 and 56.
Note that the lubricant container 75 is previously filled with the lubricant 49 in each recess 18 and the lid 22 is attached from the back side.
Procedure 1: As shown in FIG. 55A, the tube 47 is attached to one end of the lubricating member 155.

Procedure 2: As shown in FIG. 55B, the lubricating member 155 fitted with the tube 47 is inserted into each through hole 164 of the end cap 55 from the back side. As a result, the tube 47 is accommodated in the large-diameter portion 46 of the through hole 164, and the tip of the tube 47 slightly protrudes into the direction change path 5 a of the end cap 55. At this time, since the tip of the tube 47 has a shape along the rolling groove of the direction changing path 5a as described above, the tube 47 slightly protrudes into the direction changing path 5a along the rolling groove.
Procedure 3: Same as procedure 3 of the assembly procedure of the slider 40 in the tenth embodiment, that is, procedure 1 of the assembly procedure of the slider 32 in the second embodiment. See FIG. 56A.

Procedure 4: As shown in FIG. 56B, the lubricant container 75 is attached to each end cap 55 from the outside in the longitudinal direction of the slider body 4 with the surface where the circular opening 254 is formed, that is, the front facing. The circular opening 254 is not shown in FIG. At this time, the lubricating member 155 attached to each through hole 164 of the end cap 55 is inserted into each circular opening 254 of the lubricant container 75. Thereby, positioning of the lubricant container 75 with respect to the end cap 55 is achieved.
Procedure 5: The procedure is the same as the procedure 5 of the assembling procedure of the slider 40 in the tenth embodiment, that is, the procedure 3 of the assembling procedure of the slider 32 in the second embodiment. See Figure 56C.

  The linear guide device 111 of the present embodiment can easily assemble the slider 48 by the above assembling procedure, and can achieve the same effects as those of the tenth embodiment.

  As described above, the tube 47 is made of an elastically deformable polymer material and has high flexibility. Therefore, the lubricating member 155 to which the tube 47 is attached in the procedure 2 can be easily inserted into the through hole 164 having a small diameter provided in the end cap 55 while the tube 47 is elastically deformed.

  Further, in the present embodiment, the tip of the tube 47 slightly protrudes into the direction change path 5a while being along the rolling groove of the direction change path 5a of the end cap 55 as shown in FIG. 52B. With this configuration, the lubricant can be reliably applied to the rolling elements traveling on the direction change path 5a of the end cap 55 without obstructing the traveling of the rolling elements. Since the tube 47 has high flexibility and can be elastically deformed as described above, when the rolling elements traveling on the direction change path 5a of the end cap 55 collide, the tube 47 can absorb the impact and hardly break. .

  Further, as described above, the present embodiment is configured to apply the lubricant by bringing the cylindrical tube 47 into contact with the rolling elements traveling on the direction change path 5a of the end cap 55.

Therefore, a large amount of lubricant can be prevented from being consumed in a short period of time, and refueling can be performed stably for a long period of time.

  As the material of the tube 47, it is preferable to use a polymer material such as polyolefin, urethane, fluororesin, or vinyl chloride, especially polyolefin. As described above, polyolefin has a specific gravity of 1 or less and is lightweight. Therefore, when the tube 47 is made of polyolefin, a load applied from the lubricant member 155 to the lubricant container 75 is reduced, and thus the tube 47 is effective for the lubricant container 75.

  Polyolefin has high insulation as described above. Therefore, even when static electricity is generated due to friction between the direction change path 5a of the end cap 55 and the rolling elements when the slider 48 travels on the guide rail 2, the tube 47 made of polyolefin and the lubricating member 155 can be insulated. it can. For this reason, it is possible to prevent the lubricant container 75 from being damaged by static electricity.

  Among polyolefins, polyethylene is soft. For this reason, if polyethylene is used as the material of the tube 47, the lubricating member 155 attached with the tube 47 in the procedure 2 can be easily inserted through the through-hole 164 of the end cap 55. In order to give rigidity to polyethylene, it is more preferable to compound polypropylene with polyethylene.

Moreover, although the oil supply apparatus for linear guide devices of each said embodiment is provided in the both ends of the slider main body 4, it is not restricted to this, In the said 1st-3rd and 5-11 embodiments, one of the slider main bodies 4 is provided.
