The coating layer can be formed by a clear coating. For example, a transparent liquid coating is applied to the surface of the guide section (31) and dried. The surface of the guide section (31) can be formed smoothly, and through this, the frictional resistance during sliding of the moving section (33) can be reduced. The details of this clear coating are the same as those used in conventional clear coatings, particularly those intended to reduce frictional resistance.

The guide section (31) can be made of, for example, an aluminum material. In this case, in order to prevent oxidation of the surface, an anodizing coating can be preferably used, but is not limited thereto. It is not a thing.

The acetal resin is a polymer of formaldehyde or trioxane having an acetal bond in the main chain, and is excellent in electrical insulation, abrasion resistance, heat resistance, and the like, and has a characteristic that a friction coefficient is small. Therefore, when the material of the moving zone according to the present invention is used, there is less friction between the moving zone and the guide, and smoother sliding can be realized more.

That is, the guide section and the moving section made of the above-described material are formed with a smooth surface and have a small friction coefficient, so that the frictional resistance during sliding is reduced, thereby enabling smooth sliding.
