m. In particular, when focusing on the pair of reinforcing fiber members 21b and 21c opposed to the center line, the cut 29
As described later, a good contact with the guide rail 1 and the guide surface 1a can be maintained by the a and 29b to enhance the lubrication effect.

The lubrication effect can be enhanced irrespective of the width of the cuts 29a, 29b.
The width in the direction along the center line of 29b is increased by the reinforcing fiber member 21a.
When the thickness of the reinforcing fiber member is larger than the thickness of the reinforcing fiber member 21a as shown in FIG. The illustrated upper surface of 21a can be prevented from contacting the illustrated lower surfaces of the reinforcing fiber members 21b and 21c. However, when the widths of the cuts 29a and 29b are reduced so that the illustrated upper surface of the reinforcing fiber member 21a contacts the illustrated lower surface of the reinforcing fiber members 21b and 21c, the portion where the reinforcing fiber members 21b and 21c are sewn is formed. The notch 20 for inserting the guide rail is provided in the oil retaining sheet member 8a.
As shown in FIG. 5, the contact between the guide rail 1 and the guide surface 1a is deteriorated, and the refueling of the guide rail 1 is adversely affected. However, the cuts 29a, 29b having the above widths are formed.
By doing so, this is prevented and more effective refueling is performed.

FIG. 9 is a plan view showing the second oil retaining sheet member 8b. The second oil-retaining sheet member 8b has a notch 24 for guide rail insertion by cutting out a portion corresponding to the guide rail play insertion concave portion 11 of the main body case 7. Notch 24 width Z
Is larger than the width Y of the guide rail insertion notch 20 of the first oil retaining sheet member 8a so that the peripheral edge of the second oil retaining sheet member 8b does not contact the guide surface 1a. For example, when the width X of the guide surface 1a is 10 mm, the width Y of the guide rail insertion notch portion 20 of the first oil retaining sheet member 8a is 9 mm, and the width Y of the second oil retaining sheet member 8b is The width Z of the notch 24 is about 15 mm. The guide rail insertion notch portion 24 of the second oil retention sheet member 8b has its depth dimension N set to the guide rail insertion notch portion 2 of the first oil retention sheet member 8a.
The depth M is about 10 mm larger than the depth M of 0 so as not to contact the tip 1b of the guide surface 1a. These two oil retaining sheet members 8a and 8b have respective vertical dimensions L4.
