Further, the front end surface of the cylindrical portion 19 of the lubricant container 7 and the front end surface of the projection portion 43 of the lubricating member 40 are respectively processed into a curved shape of the rolling groove along the direction changing path 5a of the end cover 5 as shown in Fig. 6B.

Hereinafter, the assembly procedure of the slider 31 in the present embodiment will be described with reference to Fig. 9 .

Further, in the lubricant container 7, the lubricating member 40 is inserted into each of the recesses 18 in advance, and the cover 22 is attached from the back side to be sealed.

Procedure 1: As shown in FIG. 9A, at both end portions in the longitudinal direction of the slider body 4, the end cover 5 is disposed on the surface on which the direction changing path 5a is formed, that is, on the front side toward both ends. Next, the screw 24 is inserted into the through hole 13 of the end cover 5 to be fixed to the screw hole 11 of the slider body 4. The through hole 13 and the screw hole 11 are not shown in FIG. In this way, the installation of the end cover 5 to the slider body 4 is completed.

Thus, the mounting of the lubricant container 7 and the side seal 8 to the slider body 4 is completed.

The slider 31 can be easily assembled by the above assembly procedure. In particular, in the program 2, the four through holes 16 of the end cap 5 are respectively inserted into the tubular portion 19 of the lubricant container 7, and the positioning of the lubricant container 7 to the end cover 5 can be performed. Therefore, in the program 3, the lubricant container 7 and the side seal 8 can be easily fixed to the slider body 4 by the common screw 26. Further, as described above, since the four concave portions 18 of the lubricant container 7 respectively hold the lubricating member 40, the four lubricating members 40 can be processed once by the lubricant container 7. Therefore, not only the assembly of the slider 31 is facilitated, but also the maintenance of the slider 31 is facilitated. Further, since the lubricating member 40 can be processed one by one, the slider 31 can be uniformly supplied with oil.

The slider 31 assembled according to the above assembly procedure has a front end of the cylindrical portion 19 of the lubricant container 7 and a front end of the protruding portion 43 of the lubricating member 40, as shown in FIG. 6, exposed from the through hole 16 to the end cover 5 In the transition path 5a, a rolling groove is formed in the through hole 16 along the rolling groove of the direction changing path 5a. More specifically, the front end surface of the cylindrical portion 19 of the lubricant container 7 and the front end surface of the projection portion 43 of the lubricating member 40 form a single curved surface together with the rolling groove of the direction changing path 5a.

According to this configuration, when the slider 31 is linearly moved on the guide rail 2, it can be lubricated by the rolling element rolling on the direction changing path 5a contacting the front end surface of the projection portion 43 of the lubricating member 40. The agent is used to supply oil to the inside of the slider 31.

Further, as described above, since the front end of the cylindrical portion 19 of the lubricant container 7 and the front end of the projection portion 43 of the lubricating member 40 form a curved surface along the rolling groove of the direction changing path 5a, the rolling elements can be in the direction changing path 5a. Smooth scrolling. Therefore, the rolling element collides with the lubricating member 40 as in the above-described conventional technique, and the lubricating member 40 is broken, causing the fragment to become a foreign matter falling between the direction changing path 5a and the rolling element. Further, as in the above-described conventional technique, a step is generated between the direction changing path 5a and the lubricating member 40, and the rolling element collides with the step to cause S-shaped traveling. Therefore, damage to the rolling element and the direction changing path 5a can be prevented, and malfunction and malfunction of the slider 31 can be prevented.

Further, as described above, the lubricating member 40 is composed of 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. Therefore, the first lubricating member 41 can hold the amount of each unit volume of the lubricant smaller than that of the second lubricating member 42. With such a configuration, the second lubricating member 42 can function as a holding portion for holding the lubricant. In addition, the first lubricating member 41 can prevent the lubricant held by the second lubricating member 42 from flowing out into the direction changing path 5a of the end cover 5, and can exert a function of applying an appropriate amount of the lubricant to the application portion of the rolling element. Therefore, it is possible to suppress a large amount of lubricant from being consumed in a short period of time, and to stably supply oil for a long period of time.

Further, the materials of the first and second lubricating members 41 and 42 are not limited to the porous molded bodies having different densities as described above. The first and second lubricating members 41 and 42 may be made of different materials as long as the first lubricating member 41 can hold the amount of the lubricant per unit volume smaller than the second lubricating member 42. In addition, the first lubricating member 41 may be formed of a porous molded body, and a lubricant such as butter or lubricating oil may be filled in the concave portion of the lubricant container 7 as the second lubricating member 42. The composition of 18.

Composition. However, the present invention is not limited thereto, and the concave portions 18 and 180 of the lubricant containers 7 and 70 to 74 may be configured to hold the lubricant itself such as butter or lubricating oil. For example, in the first embodiment, the lubricant may be filled in a space formed by the concave portion 18 of the lubricant container 7 and the tubular portion 19. Further, in the second embodiment, the lubricant may be filled in a space formed by the recessed portion 18 of the lubricant container 70, the circular opening 25, and the through hole 16 of the direction changing path 5a of the end cover 5. .

Further, in each of the above-described embodiments, the porous molded body containing the lubricant is used as the lubricating members 40 and 400 to 402. However, the present invention is not limited thereto, and the porous molded body for elastic deformation can be used (hereinafter referred to as " The porous elastomer ") is a lubricant impregnating member 40, 400-402. Thereby, when the rolling elements that travel on the direction changing path 5a contact the lubricating members 40, 400 to 402, the lubricating members 40, 400 to 402 can be elastically deformed. Therefore, it is possible to prevent the abrasion of the lubricating members 40, 400 to 402 or the falling in the direction changing path 5a, and to prevent the deterioration of the actuation of the sliders 31 to 36 or the deterioration of the service life.

The groove is the same height. Therefore, the protruding portion 43 of the lubricating member 40 is not broken even if it is collided by the rolling elements. Since the POM has elasticity as described above, this effect can be maximized when the lubricating member 40 is constituted by POM, and the lubricating member 40 is well protected. Further, in this regard, the above-described respective embodiments other than the first embodiment are also the same.

Further, as shown in FIG. 6B, when the tubular portion 19 of the lubricant container 7 is fitted to the protruding portion 43 of the lubricating member 40, the soft PE is used as the material of the lubricating member 40, since the projection 43 can be made. It is preferable to be easily fitted to the tubular portion 19. Furthermore, in order to make the PE rigid, it is more preferable if the PP can be mixed with the PE.

Further, as the other materials of the lubricating members 40 and 400 to 402, animal hair such as wool, wholly aromatic polyamine, glass, cellulose, nylon, polyester, polyether, polyolefin, and enamel may be used.
