FIG. 7 is a plan view showing a non-contact type oil retaining sheet member 8c disposed at the lowermost portion of the main body case 7. This non-contact type oil retaining sheet member 8b is the same as the non-contact type oil retaining sheet member 8b shown in FIG. 6 except for the oil supply units 27a to 27c, and the other parts are the same. A detailed description is omitted.

In the oil retaining sheet member 8 shown in FIG. 4, the above-mentioned contact type oil retaining sheet members 8a and non-contact type oil retaining sheet members 8b are alternately stacked and arranged. The sheet member 8c is arranged, and the sheet member 8c is made up of a total of six sheets and bound by a binding body 32. Such an oil retaining sheet member 8 is stored in the main body case 7 as shown in FIG.
The bundling body 32 is pinched to push the oil retention sheet member 8 into the main body case 7, and the bundling body 32 is pinched to hold the oil retention sheet member 8
Can be easily taken out of the main body case 7. The above-mentioned oil retaining sheet members 8a to 8c are stacked as shown in FIG. 4, and are stored in the main body case 7 shown in FIG.
Is inserted, and the lid 9 is closed, the rod-shaped members 13a to 13a-1 are closed.
3c is engaged with the engaging recesses 18a to 18c to be held in position. Therefore, the vicinity of the guide rail insertion notches 20, 24 of the oil retaining sheet member 8 is the guide rail 1
Is accurately held at a predetermined position with respect to the guide surface 1A,
The positional relationship is such that the lubrication of the guide surface 1A is effectively performed via the reinforcing fiber members 21a to 21c.

When the oil supply device 5 is mounted as shown in FIG. 2, the guide rail insertion notches 20 and 24 of the oil retaining sheet members 8a to 8c are inserted into the guide surfaces 1 of the guide rail 1.
A is located, and at this time, each of the reinforcing fiber members 21a to 21c of the contact type oil retaining sheet member 8a is guided by the guide surface 1A.
, But the peripheral edges 28a to 28c of the guide rail insertion notches 24 in the non-contact type oil retaining sheet members 8b and 8c.
28c is not in contact with the guide surface 1A.

When the car 2 is driven up and down in this state,
The contact-type oil-retaining sheet member 8a at the portion where the reinforcing fiber members 21a to 21c in contact with the guide surface 1A are sewn follows the deformation. That is, as shown in FIG. 8, when the car 2 rises in the direction of the arrow together with the refueling device 5, the contact type oil retaining sheet member 8 a at the portion where the reinforcing fiber members 21 a to 21 c are sewn is deformed downward, while As shown in FIG. 9, when the car 2 descends together with the oil supply device 5, the contact type oil retaining sheet member 8 a at the portion where the reinforcing fiber members 21 a to 21 c are sewn is deformed upward. This swing deformation
This is smoothly performed by the cut 29 shown in FIG.

Further, in the non-contact type oil retaining sheet members 8b and 8c alternately arranged with the contact type oil retaining sheet members 8a, the peripheral edges 28a to 28c of the notch 24 for inserting the guide rail do not contact the guide surface 1A. Therefore, the space 30 is formed between the guide surface 1A and the space 30 helps the contact portion of the contact type oil retaining sheet member 8a to smoothly deform and move up and down. Therefore, the contact type oil retaining sheet member 8a deforms and applies the lubricating oil impregnated thereto to the guide surface 1A of the guide rail 1, forms an appropriate oil film on the surface, and maintains a good lubrication state. . Also,
When the oil retaining sheet member 8a at the portion where the reinforcing fiber members 21a to 21c are sewn is deformed and moved into the space 30, the peripheral portion of the guide rail insertion notch portion 24 of the non-contact type oil retaining sheet member 8c is particularly contacted. The reinforcing fiber member 2
Lubricating oil excessively supplied to 1a to 21c is absorbed by the non-contact type oil retaining sheet member 8c, and excessive lubrication to the guide surface 1A is prevented. In this way, unlike the conventional case where the guide surface 1A and all the oil retaining sheet members are in contact with each other, the reinforcing fiber members 21a to 21c can be prevented from being loosened or broken, and the guide surface of the guide rail 1 can be prevented. 1A can be effectively refueled. According to the experiment, even after continuous use for 720 hours, the reinforcing fiber members 21a to 21c were not damaged.

Next, the supply of lubricating oil to the oil supply device 5 will be described. When the lubricating oil impregnated in the oil retaining sheet member 8 becomes insufficient due to the lubricating operation by the lubricating device 5 described above, the lid 9 of the lubricating device 5 in the state of being attached to the elevator is opened as shown in FIG. A predetermined amount of lubricating oil, here 250 cc to 300 cc, is injected into an oil storage space 33 formed by the upper surface of the contact type oil retaining sheet member 8a disposed on the uppermost portion of the oil retaining sheet member 8 and the upper peripheral edge of the main body case 7. . At this time, since the oil reservoir space 33 is provided, the lid 9 can be closed at the stage where the lubricating oil has been supplied to the same portion, and the supply operation can be completed. After that, or at the stage when lubricating oil is injected, the lubricating portions 27a to 2
The lubricating oil is quickly impregnated into the other lower non-contact type oil retaining sheet members 8b and 8c located below from 7c. Lubricating oil that has not been absorbed in the lower part from each of the lubricating parts 27a to 27c is stored in a space 33 formed in the upper part of the main body case 7 shown in FIG. In addition, since the non-contact type oil retaining sheet member 8c located at the lowermost portion is not provided with an oil supply portion, the lubricating oil from the oil supply portions 27a to 27c of the contact type oil retaining sheet member 8a located immediately above is not supplied. The non-contact type oil retaining sheet member 8c is directly impregnated, and thus the lubricating oil is supplied to the guide surface 1A from the reinforcing fiber members 21a to 21c of each oil retaining sheet member 8, and the oil retaining sheet member 8 Can be replenished in a short time. This is the case where a predetermined amount of oil is supplied from an oil supply portion 27a to 27c formed on the oil retaining sheet member 8 with an oil grease or the like, or only when a small amount of lubricating oil is supplied to the upper surface of the uppermost oil retaining sheet member 8. In comparison, it can be performed efficiently in a short time and by preventing overflow.

In the above-described embodiment, the number of the oil retaining sheet members 8 is six, but any number can be selected. In any case, at least 5 mm or more is provided on the upper part of the main body case 7. The height of the main body case 7 is selected so as to form the oil reservoir space 33 having a height. Further, the number and shape of each of the rod-shaped members 13a to 13c and the lubricating portions 27a to 27c can be arbitrarily set.
The present invention can be applied to the oil retaining sheet 8 having no c.
