The holding portion 8 can take various configurations. Here, the height of the holding portion 8 is lower than the outer peripheral side wall of the oil supply case 1 formed at a position corresponding to the insertion recess 4, and the lubricating oil in the oil supply case 1 is used. The holding portion 8 is formed at a position higher than the surface. More specifically, a plurality of upright pieces 9 are discretely established at the bottom of the fueling case 1, and the receiving portions 10 are formed at the same height position of the upstanding pieces 9. Constitutes a holding portion 8 that receives a plurality of locations on the outer peripheral portion of the siphoning member 3.

  The oil supply sheet unit 2 is configured as a laminate composed of an oil permeable sheet 11 whose details will be described later, and a pair of non-oil permeable sheets 12 and 13 sandwiching the oil permeable sheet 11 from above and below, at an appropriate position. It is bundled together by fixing means such as a tack provided on the.

  The non-oil permeable sheets 12 and 13 disposed on both the upper and lower sides of the oil supply sheet unit 2 are rectangular sheets that are flexible but not oil-impregnated, and are formed in the insertion recesses 4 formed in the oil supply case 1. Corresponding portions are formed by cutting out, and insertion holes 14 to 16 are provided at positions where the columnar bodies 5 to 7 of the oil supply case 1 are respectively inserted in the stacking direction. Further, the non-oil permeable sheets 12 and 13 are composed of a soft plastic sheet or foamed plastic sheet that does not have oil impermeability but oil resistance, or a closed cell urethane sheet, a polyethylene sheet, and a polypropylene sheet. The thickness is 1-7 mm, desirably 1.5-5 mm.

  Further, the oil permeable sheet 11 of the oil supply sheet unit 2 is formed by cutting out a rectangular sheet as shown in the perspective view of FIG. 2, but the guide rail in a saturated state sufficiently containing lubricating oil. The guide surface has such a thickness and width that an appropriate amount of oil is supplied without being supercharged. The oil permeable sheet 11 is composed of a sheet made of a woven or non-woven fiber using a capillary action, and has a thickness of 2 mm or less, preferably 1 mm or less.

The oil permeable sheet 11 has insertion holes 20 to 16 having insertion holes 14 to 16 into which the columnar bodies 5 to 7 of the oil supply case 1 are inserted so that the oil permeable sheet 11 can be held at a predetermined position in the oil supply case 1. It has a main body part 22 formed. The main body portion including the insertion holding portions 20 to 22 has a size accommodated within a projection area substantially the same as that of the non-oil permeable sheets 12 and 13 shown in FIG. However, the connecting oil guiding portion 28 extending beyond the projected area is formed, and the connecting oil guiding portion 28 has the insertion hole 15 of the insertion holding portion 23 aligned with the insertion hole 15 of the insertion holding portion 21. As a result, it is used by being folded back to the lower surface side, and as a result, it comes into contact with the suction sheet 3 described later in detail.

  Further, the oil permeable sheet 11 has contact portions 24 to 26 formed to extend in three directions at positions corresponding to the insertion recesses 4. These contact portions 24 to 26 are folded and shown in FIG. 1. It is kept in contact with the oil supply bellows 17 to 19 by the fixing means. Further, the main part of the oil permeable sheet 11 has a relatively narrow oil guide portion 27 formed so as to connect the insertion holding portions 20 to 22. Since the oil-permeable sheet 11 has a thickness of 2 mm or less, these portions can be easily formed by notching or the like, and the cross-sectional areas of the oil guide portion 27 and the connecting oil guide portion 28 are also provided. In particular, the width can be easily adjusted, and an appropriate amount of oil can be supplied so as not to supercharge the guide surface of the guide rail in a saturated state sufficiently containing the lubricant.

  The oil supply sheet unit 2 formed by sandwiching the oil permeable sheet 11 between the pair of non-oil permeable sheets 12 and 13 is supplied with oil so that the guide surface of the guide rail is positioned in the insertion recess 4 formed in the oil supply case 1. In the state where the device is attached, the oiling bellows 17 to 19 which are slightly protruded inwardly from the outer peripheral side wall of the oiling case 1 at the position corresponding to the insertion recess 4 and can be in direct contact with the three guide surfaces of the guide rail, respectively. And have. These oil supply bellows parts 17-19 penetrate a laminated body also using a part of the above-mentioned fixing means which bundles the laminated body of the oil-permeable sheet 11 and the non-oil-permeable sheets 12 and 13 mentioned above. It is fixed by providing tack or sewing in the direction. The oil supply bellows parts 17 to 19 are preferably made of nylon, urethane, or polyester-based simple substance or composite nonwoven fiber.

  The sucking member 3 disposed at the lower part of the above-described oil supply sheet unit 2 is composed of a nonwoven fiber bundled sheet made of natural fibers or synthetic fibers, and has a thickness of 3 mm or less, and the lubricating oil clay becomes high. Even in winter, it has sufficient oil retention capacity and oil transfer capacity, and always maintains a saturated state of lubricating oil.

  However, the sucking member 3 may be of a construction other than the generally known sheet. However, the sucking member 3 here is formed by cutting out a rectangular sheet as shown in FIG. 1 and has insertion holes 14 to 16 into which the columnar bodies 5 to 7 of the oil supply case 1 are respectively inserted. Lubricating oil in the oil supply case 1 by using the oil feeding side holding portion 29 which is a substantially U-shaped main portion and the portion corresponding to the insertion recess 4 in the state of a rectangular sheet without being cut off and folded downward It has a suction side portion 30 that is used by being immersed therein. If such a sheet-like sucking member 3 is used, a single rectangular sheet can be cut out and integrally formed. Therefore, the number of parts can be reduced, and the sucking side portion 30 can be easily obtained by folding. .

  In the assembled state, the oil permeable sheet 11 of the oil supply sheet unit 2 folds the connecting oil guide portion 28 shown in FIG. 2 downward, and the insertion hole 15 of the insertion holding portion 23 is inserted into the insertion holding portion. It matches with the insertion hole 15 of 21. For this reason, the folded insertion holding portion 23 comes into contact with the vicinity of the insertion hole 15 of the suction member 3 shown in FIG. 1, and the connecting oil guide portion 28 connecting the folded insertion holding portion 23 and the insertion holding portion 21 is The oil passage portion is located on the outer peripheral portion of the oil supply sheet unit 2 and guides the lubricating oil sucked up from the suction member 3 to the main portion side of the oil permeable sheet 11. In this way, the oil permeable sheet 11 can also be formed integrally by cutting out one rectangular sheet, so that the number of parts is reduced, and the main portion of the oil permeable sheet 11 and the sucking member 3 are connected by folding. It can be easily connected.

  In this embodiment, an oil supply sheet unit 2 comprising an oil permeable sheet 11 and non-oil permeable sheets 12 and 13 disposed above and below the oil permeable sheet 11 is bundled by fixing means provided at appropriate positions. However, the suction member 3 may be regarded as a single laminated body in a state in which the suction member 3 is disposed at the lower portion of the above-described oil supply sheet unit 2 and may be integrally formed by bundling them with a common fixing means. In this case, the insertion holding part 23 of the oil permeable sheet 11 shown in FIG. 2 and the oil feeding side holding part 29 which is the main part of the suction member 3 shown in FIG. Then, since both can be integrated by the fixing means, the contact portion can always be kept in a good contact state. Moreover, since the insertion holes 14 to 16 formed in the laminating direction of the oil supply sheet unit 2 and the suction sheet 3 can be aligned in advance in the laminating direction, when the oil supply sheet unit 2 and the siphoning member 3 are stored in the oil supply case 1, The operation | work which inserts the columnar bodies 5-7 in the insertion holes 14-16 becomes easy.

  Regardless of which is adopted as the structure of the laminated body described above, when assembling as a guide rail oil supply device for an elevator, the oil surface is not higher than the height of the receiving portion 10 of the upright portion 9 formed in the oil supply case 1. A predetermined amount of lubricating oil is injected into the oil supply case 1. Thereafter, when the laminated body is placed in the fuel supply case 1, the positioning is performed by inserting the insertion holes 14 to 16 of the fuel supply sheet unit 2 and the suction member 3 into the columnar bodies 5 to 7 provided at the bottom of the fuel supply case 1, The position and height are determined by matching the outer periphery of the suction member 3 and the fueling sheet unit 2 with the holding part 8 formed by the receiving parts 10 of the plurality of standing parts 9 formed at the bottom of the fueling case 1 shown in FIG. . At this time, the suction member 3 is held at a predetermined height above the liquid level of the lubricating oil by the height of the receiving portion 10. The suction member 3 and the oil supply sheet unit 2 are not necessarily arranged almost horizontally, but are arranged almost horizontally here. At this time, the oil feeding side holding portion 29 which is the main portion of the sucking member 3 is positioned substantially horizontally and above the surface of the lubricating oil, and only the sucking side portion 30 which is a part of the sucking member 3 is lubricated. It extends to the bottom in the case 1 and is inserted into the lubricating oil.

  Even if the oil supply sheet unit 2 and the suction member 3 in the oil supply case 1 are held almost horizontally or slightly tilted, the oil supply sheet unit 2 and the suction member 3 when they are stored in the oil supply case 1 are vertical. The holding portion 8 is formed so that the projection surface is in the fuel supply case 1. In particular, it is desirable to cut and form the suction member 3 so that a part of the suction member 3 is not located above the portion corresponding to the insertion recess 4. With such a configuration, even if the lubricating oil is dropped from the oil supply sheet unit 2 and the suction member 3, the dropped lubricating oil can be reliably collected in the oil supply case 1.

  Further, at least one standing piece 9A different from the above-described standing piece 9 is provided in the oil supply case 1, and when this standing piece 9A holds the suction member 3 at a position regulated by the holding portion 8, It has a surface that contacts the lower surface of the wicking member 3. The standing piece 9 described above determines the height positions of the sucking member 3 and the oil supply sheet unit 2, whereas the standing piece 9 </ b> A is formed in a plate shape that contacts the lower surface of the sucking member 3, and the sucking member Even if excessive lubricating oil is supplied to 3, the excessive lubricating oil is guided so as to be dropped or dropped, and the excessive lubricating oil can be reliably recovered in the oil supply case 1. .

  As can be seen from this description, the columnar bodies 5 to 7, the plurality of upright pieces 9, and the upright pieces 9 </ b> A provided in the refueling case 1 function in a similar manner, and may be configured to have a plurality of functions at the same time. it can. For example, the columnar bodies 5 to 7 have a large-diameter portion in the middle of the axial direction. If the insertion depth of the suction member 3 and the fueling sheet unit 2 is regulated by the large-diameter portion, the holding portion 8 by the standing piece 9 is used. These functions can also be used, or the upright piece 9 and the upright piece 9A can be formed integrally so that both functions can be used together.

  When the suction member 3 and the oil supply sheet unit 2 are completely stored in the oil supply case 1, the lubricating oil in the oil supply case 1 is sucked up from the suction side portion 30 of the suction member 3 and is supplied to the oil supply side holding portion 29 which is the main portion. Supplied up to. Thereafter, the oil is introduced into the oil permeable sheet 11 of the oil supply sheet unit 2 through the connection oil guide portion 28. Even if the guide rail oil supply device of the elevator is not used and the suction member 3 is saturated, excess lubricating oil drops or drops along the upright piece 9A located at the lower portion of the suction member 3 as described above. It is collected in case 1. Even if the oil permeable sheet 11 is saturated, the oil permeable sheet 11 is sandwiched between the non-oil permeable sheets 12 and 13 disposed above and below, so that undesired dripping does not occur.

  When the guide rail oil supply device of the elevator is operated and lubricating oil is supplied from the oil supply bellows 17 to 19 to the guide surface of the guide rail, the suction side portion 30 of the suction member 3 or the oil permeable sheet 11 is connected. Lubricant adjusted to an appropriate amount by the oil guide portion 28 or the oil guide portion 27 is supplied, so that a desired amount of oil can be supplied while preventing excessive oil supply to the guide surface.

  As described above, according to the guide rail oil supply device for an elevator according to the present embodiment, the lubricating oil sucked up from the oil supply case 1 through the sucking member 3 is supplied to the oil permeable sheet 11. Since the oil permeable sheet 11 is sandwiched between the non-oil permeable sheets 12 and 13 arranged above and below, the oil permeable sheet 11 is supercharged as in the case of the oil permeable sheet 11 alone while maintaining a necessary supply amount. The lubricating oil can be prevented from dripping. In addition, since the oil permeable sheet 11 is not a large volume as in the prior art but is in the form of a sheet, the cross-sectional area or width that determines the oil feed amount in the lubricating oil supply path can be easily increased or decreased. Accordingly, it is possible to easily prevent the conventional supercharging, while maintaining the necessary supply amount to the oiling bellows 17 to 19.

  Comparing a more specific preferred embodiment with the conventional configuration, in the conventional configuration, when the fuel supply bellows 17 to 19 are moved up and down while contacting the guide surface of the guide rail, the sliding distance is 1 km. Until that time, the thickness of the oil film rapidly exceeded 50 μm, and it was impossible to measure with a simple measuring instrument. On the other hand, in the preferred embodiment, when the oil supply bellows 17 to 19 are raised and lowered while being in contact with the guide surface of the guide rail, the thickness of the oil film increases until the sliding distance is 1 km. However, the gradient was gentle compared to the conventional case, and after the sliding distance exceeded 1 Km, the thickness of the oil film was stable at about 20 μm. In this way, in the preferred embodiment, the necessary supply amount can be stably maintained while easily preventing the conventional supercharging.

Moreover, since the oil-permeable sheet | seat 11 is a sheet form of 2 mm or less, the notch process etc. are easy, can be given various shapes, and can also be bent easily. Therefore, the insertion holding part 21 having the insertion hole 15, the insertion holding part 23 having the insertion hole 15, and the connecting oil guide part 28 that connects between the insertion holding part 21 and the insertion holding part 23 can be easily integrated. The connecting oil guide portion 28 can be folded and used so that the insertion holes 15 of the insertion holding portion 21 and the insertion holding portion 23 are matched. Lubricating oil sucked from the sucking member 3 by making the folded insertion holding portion 23 easily contact with the vicinity of the insertion hole 15 of the sucking member 3 and being positioned outside the oil supply sheet unit 2 by the connecting oil guide portion 28. It is possible to easily obtain an oil passage part that guides the oil permeable sheet 11 to the main body part side. The connecting oil guide portion 28 is formed integrally with the main portion of the oil permeable sheet 11 or separated from the oil permeable sheet 11 and configured separately, and then the oil permeable sheet 11 and the sucking member 3 are formed. It is possible to connect so as to be an oil guide portion between them, but when the oil guide portion for connection 28 is formed integrally with the oil permeable sheet 11 as shown in FIG. 2, it is created by cutting out one sheet. Therefore, the number of parts can be reduced and the configuration can be simplified.

  When the suction side portion 30 is made of a sheet having a thickness of 3 mm or less as in the case of the oil permeable sheet 11 described above, its notch processing and the like can be easily performed, and various shapes can be given, and it can be easily bent. You can also The oil feeding side holding portion 29 and the suction side portion 30 can be easily formed integrally, and the suction side portion 30 can be easily bent and immersed in the lubricating oil. Further, a suction member 3 is disposed above the oil level of the lubricating oil in the oil supply case 1 so that the suction side portion 30 is immersed in the lubricating oil in the oil supply case 1 and sucked up. Since the permeable sheet 11 is supplemented with lubricating oil, the width of the suction side portion 30 is adjusted as compared with the case where the oil retaining member is directly immersed in the lubricating oil in the oil supply case 1 as in the prior art. It becomes possible to easily increase or decrease the amount of oil to be supplied, and appropriate replenishment can be performed while preventing supercharging. Moreover, since the suction member 3 is also in the form of a sheet, the cross-sectional area or width that determines the amount of oil to be fed in the lubricating oil supply passage can be easily increased or decreased, and combined with the oil-permeable sheet 11. By using this, it becomes easy to balance the amount of oil sent between them, and a synergistic effect can be expected.

  When adjusting the replenishment amount from the suction side portion 30 of the suction member 3 to the oil permeable sheet 11, the width of the suction side portion 30 can be changed as described above, but as shown in FIG. When the suction side portion 30 is formed in the suction member 3 by notching, a plurality of suction side portions 30A and 30B are formed in advance using a portion corresponding to the insertion recess 4, and lubrication in the oil supply case 1 is performed. You may make it increase / decrease the replenishment amount as a whole by adjusting the number of the suction side parts 30A and 30B immersed in oil. In particular, in such a configuration, the replenishment amount can be easily adjusted by increasing or decreasing the number of suction side portions 30A and 30B of the suction member 3 while using the same structure as the oil supply device. be able to.

  4 and 5 are an exploded perspective view and a perspective view of main parts of a guide rail fueling device for an elevator according to another embodiment of the present invention.

  In this embodiment, like the oil supply sheet unit 2 described in the previous embodiment, an oil supply sheet constituted by sandwiching one oil permeable sheet 11 between two non-oil permeable sheets 12 and 13. Two units 2A and 2B are used, and a spacer 31 made of a non-oil permeable sheet is arranged between the two oil supply sheet units 2A and 2B, and described in the previous embodiment below the oil supply sheet unit 2B located at the lower part. The sucked-up members 3 are arranged and the whole is bundled by a fixing means to form a total of eight laminated bodies.

  Next, the connection between the common wicking member 3 and the oil permeable sheets 11 of both the oil supply sheet units 2A and 2B will be described.

  First, the connection between the oil supply sheet unit 2B located at the lower portion and the suction member 3 is the same as the configuration of the oil supply sheet unit 2 and the suction member 3 shown in FIG. As shown in FIG. 4, the oil permeable sheet 11 sandwiched between the non-oil permeable sheets 12 and 13 of the oil supply sheet unit 2B folds the insertion holding portion 23B of the oil permeable sheet 11 downward, and this folded insertion The holding portion 23 </ b> B is in contact with the vicinity of the insertion hole 15 of the suction member 3. On the other hand, the oil supply sheet unit 2A located in the upper portion is folded back until the insertion holding portion 23A of the oil permeable sheet 11 is interposed between the folded back insertion holding portion 23B of the fuel supply sheet unit 2B and the suction member 3. .

  As described above, when the fuel supply sheet units 2A and 2B having substantially the same configuration are used, the insertion holding portions 23A and 23B of both are positioned at substantially the same place as shown in FIG. If the insertion holding portions 23A and 23B of both the oil permeable sheets 11 have the same configuration, the insertion holding portion 23B of the lower oil supply sheet unit 2B is connected to the insertion holding portion 23A of the upper oil supply sheet unit 2A. Compared with this, a bend is formed, but since the same part is formed of a sheet and has flexibility, it can be easily bent and absorbed. In addition, since both the fuel supply sheet units 2A and 2B can use the same structure, an inexpensive oil supply apparatus can be obtained as a whole. However, the oil supply sheet units 2A and 2B may be configured so that the lengths of the insertion holding portions 23A and 23B are different from each other.

  Thus, the oil permeable sheet 11 and the sucking member 3 of the oil supply sheet unit 2A are connected to each other, and the oil permeable sheet 11 and the sucking member 3 of the oil supply sheet unit 2B are connected to each other so as to be able to send oil. By the connection using the two insertion holding portions 23A and 23B, the lubricating oil from the suction member 3 is supplied to the oil permeable sheet 11 of the oil supply sheet unit 2A and the oil permeable sheet 11 of the oil supply sheet unit 2B, respectively. Will be supplied.

  The spacer 31 arranged between the oil supply sheet unit 2A and the oil supply sheet unit 2B is formed of a non-oil permeable sheet and has substantially the same shape as the oil supply sheet units 2A and 2B arranged up and down as shown in FIG. 1 is formed in a substantially U shape having insertion holes 14 to 16 into which the columnar bodies 5 to 7 of the oil supply case 1 shown in FIG. The spacer 31 can be omitted.

  According to the elevator guide rail refueling device in this embodiment, the oil supply sheet units 2A and 2B configured by sandwiching the oil permeable sheet 11 between the non-oil permeable sheets 12 and 13 are used as one handling unit. The number of oil supply sheet units can be easily increased or decreased according to the amount of oil supplied to the guide surface of the guide rail. In addition, when a plurality of oil supply sheet units are used, a spacer 31 formed of a non-oil permeable sheet is sandwiched between the oil supply sheet units 2A and 2B. The movement of the lubricating oil can be eliminated or restricted. For example, the movement of the lubricating oil between the two oil supply sheet units 2A and 2B arranged up and down through the oil supply bellows parts 17 to 19 is suppressed, and the oil supply through the respective insertion holding parts 23A and 23B is almost limited. it can. As a result, the oil supply from the oil supply sheet unit 2A to the guide surface of the guide rail and the oil supply from the oil supply sheet unit 2B to the guide surface of the guide rail are adjusted in a well-balanced manner, and the respective oil supply amounts are adjusted. It becomes easy.

  Also in the present embodiment, the oil permeable sheet 11 is sandwiched between the non-oil permeable sheets 12 and 13 disposed above and below, and the oil supply case 1 is used to supply lubricating oil to the oil permeable sheet 11. In the configuration using the sucking member 3 in which the sucking side portion 30 is immersed in the inside lubricating oil, the same effect as in the previous embodiment can be obtained.

  In the above-described embodiment, two sets of oil supply sheet units 2A and 2B having substantially the same configuration are used in an overlapping manner, but five non-oil permeable sheets and two oil permeable sheets are used. Two configurations in which one oil permeable sheet is sandwiched between non-oil permeable sheets may be formed. As can be seen from this description, it is sufficient to have a configuration in which one oil-permeable sheet 11 is sandwiched between two non-oil-permeable sheets 12 and 13, and the use of a non-oil-permeable sheet and an oil-permeable sheet The number of sheets can be arbitrarily set, and the number of handling units as a unit can be arbitrarily determined.

  FIG. 6 is a perspective view showing an oiling sheet unit which is a main part of an elevator guide rail oiling device according to another embodiment of the present invention.

  The oil supply sheet units 2A and 2B configured by sandwiching one oil-permeable sheet between two non-oil-permeable sheets are the same as those described with reference to FIGS. A plurality of oil supply holes 32 penetrating the whole in the direction are formed with a substantially target positional relationship. The oil supply hole 33 formed in the oil permeable sheet 11 positioned below the oil supply hole 32 of the non-oil permeable sheet 12 positioned above is smaller. Although not shown, the oil supply sheet unit 2B disposed further below also forms an oil supply hole.

  Now, when lubricating oil is poured from the oil supply hole 32 of the non-oil permeable sheet 12 of the oil supply sheet unit 2 </ b> A located at the top, the oil is supplied from the oil supply hole 32 of the non-oil permeable sheet 12 to the oil permeable sheet 11. . Since the oil supply hole 33 of the oil permeable sheet 11 is small, the oil permeable sheet 11 flows into the oil permeable sheet 11 of the oil supply sheet unit 2B located further down, and simultaneously penetrates into the oil permeable sheet 11 of the oil supply sheet unit 2A located at the top. Go on.

  When such an oil supply sheet unit 2A, 2B is used to constitute an elevator guide rail oil supply device, it is sucked up through the suction member 3 soaked in the lubricating oil of the oil supply case 1 as described above at the time of installation or replacement thereof. In addition to the oil conduit that supplies the oil permeable sheet 11, an oil conduit that supplies lubricating oil in another container from the oil supply hole 32 of the non-oil permeable sheet 12 of the oil supply sheet unit 2 </ b> A located at the top. Can be formed. By using these two oil passages, the oil permeable sheets 11 of both the oil supply sheet units 2A and 2B can be rapidly saturated with the lubricating oil.

  In each embodiment mentioned above, the insertion holes 14-16 formed in each oil supply sheet unit etc. are inserted in the three columnar bodies 5-7 established in the bottom face of the oil supply case 1, and positioning of each oil supply sheet unit etc. is stopped. However, the number, position, shape, and the like of the columnar bodies 5 to 7 can be arbitrarily set, and other positioning means can be employed. In addition, the connecting oil guide portions 28A and 28B in the oil permeable sheet 11 in each oil supply sheet unit are formed so as to be positioned in the vicinity of the columnar body 6, but may be provided at other shifted positions or the oil supply sheet unit. Each may be provided at a different position, or a plurality of oil may be received in one fueling sheet unit.

  Moreover, various forms are possible when the elevator is used as a guide rail fueling device. For example, when only the effect of the oil supply sheet unit 2 using the oil permeable sheet 11 is utilized, the oil permeable sheet 11 having a thickness of 2 mm or less is sandwiched between the non-oil permeable sheets 12 and 13 disposed above and below the sheet. The configured oil supply sheet unit 2 is used in the same manner, but the suction member 3 is not limited to a sheet, and a general suction member that is partially immersed in the lubricating oil in the oil supply case 1 is used. A configuration in which the lubricating oil sucked up by the member is supplied to the oil permeable sheet 11 of the oil supply sheet unit 2 can also be adopted. In this case, the lubricating oil sucked up from the oil supply case 1 through the suction member is supplied to the oil permeable sheet 11, and the oil permeable sheet 11 is arranged on the top and bottom of the non-oil permeable sheet 12. , 13, so that the required amount of supply to the guide surface of the guide rail is maintained, and supercharging as when using a material having a sufficient volume corresponding to the oil permeable sheet 11 is performed. Can be prevented. Moreover, since the oil permeable sheet 11 is a sheet having a thickness of 2 mm or less, the cross-sectional area or width that determines the amount of oil fed in the lubricating oil supply path can be easily increased or decreased. Thus, it is possible to easily prevent the conventional supercharging, while maintaining the necessary supply amount.
