Abstract

Provided are a sliding instrument having a low frictional resistance to the snow surface, the ice surface, or the water surface and having excellent sliding performance and a method for manufacturing the sliding instrument. A sliding instrument to slide on snow, ice, or water includes a sliding surface (1) to come into contact with the snow surface, the ice surface, or the water surface, and the sliding surface (1) has a surface roughness Ra of 1.0 μm or less. A method for manufacturing the sliding instrument includes polishing a sliding surface (1) using a polishing composition slurry containing abrasives to make the sliding surface (1) have a surface roughness Ra of 1.0 μm or less.

First claim

The invention claimed is:

1. A sliding instrument to slide on snow, ice, or water, the sliding instrument comprising:
a sliding surface to come into contact with a snow surface, an ice surface, or a water surface, the sliding surface having a surface roughness Ra of 0.12 μm or less.

2. The sliding instrument according to claim 1 , wherein the sliding surface has a surface roughness Ra of 0.1 μm or less.

3. The sliding instrument according to claim 1 , wherein the sliding surface is coated with a lubricant coating.

4. A method for manufacturing a sliding instrument to slide on snow, ice, or water, the method comprising:
polishing a sliding surface to come into contact with a snow surface, an ice surface, or a water surface, with a polishing composition slurry containing abrasives to make the sliding surface have a surface roughness Ra of 0.12 μm or less.

5. The method for manufacturing a sliding instrument according to claim 4 , wherein the polishing makes the sliding surface have a surface roughness Ra of 0.1 μm or less.

6. The method for manufacturing a sliding instrument according to claim 4 , further comprising, after the polishing, applying a lubricant coating onto the polished sliding surface.

7. The sliding instrument according to claim 2 , wherein the sliding surface is coated with a lubricant coating.

8. The method for manufacturing a sliding instrument according to claim 4 , further comprising, after the polishing, applying a lubricant coating onto the polished sliding surface.

9. The method for manufacturing a sliding instrument according to claim 5 , further comprising, after the polishing, applying a lubricant coating onto the polished sliding surface.

10. The sliding instrument according to claim 1 , wherein the sliding surface has a surface roughness Ra of 0.12 μm or less and wherein the sliding instrument comprises a resin.

11. The method for manufacturing a sliding instrument according to claim 4 , wherein the polishing makes the sliding surface have a surface roughness Ra of 0.12 μm or less and wherein the sliding instrument comprises a resin.

12. The sliding instrument of claim 1 , wherein the sliding surface comprises a resin material.

13. The sliding instrument of claim 12 , wherein the resin material is selected from the group consisting of polyethylene, polypropylene, polybutene, polyacetal, polymethacrylate, polytetrafluoroethylene, and combinations thereof.
