SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a guide rail with a guide rail play insertion recess formed in a guide rail play insertion recess at a portion corresponding to a guide surface of the guide rail. In a guide rail lubricating apparatus in which a plurality of oil retaining sheet members having notches for guide rail insertion corresponding to the concave portions are arranged in a stack, a plurality of the oil retaining sheet members are at least a first oil retaining sheet member and a second oil retaining sheet member. The first oil retaining sheet member is provided with a reinforcing fiber member at a portion where the notch portion for inserting the guide rail is formed, and the reinforcing fiber member is formed by combining the two oil retaining sheet members. The second oil retaining sheet member is formed so as to be in contact with the guide surface, and is formed by forming the guide rail insertion notch having a size that does not contact the guide surface.

In the guide rail oil supply device according to the present invention, a reinforcing fiber member is provided at the portion where the guide rail insertion notch is formed as described above, and the reinforcing fiber member is brought into contact with the guide surface. Since the oil retaining sheet member is configured to have a combination portion of the oil sheet member and a second oil retaining sheet member formed by forming a cutout portion for inserting a guide rail having a size that does not contact the guide surface, For example, when the device is mounted on an elevator car and moved up and down, the portion of the first oil retaining sheet member to which the reinforcing fiber member is attached is deformed along with the elevation and does not contact the guide surface of the second oil retaining sheet member. The notch for inserting the guide rail of the size allows this deformation, the contact part with the guide surface changes as it moves up and down, and it contacts only at the same place as before. Thereby improving the life of the reinforcing fiber members as compared with the case where had.
