Claims

[Claims for Utility Model Registration] (1) A surface layer whose outer periphery and inner periphery are made of a flexible elastic material and which are concentric with each other; A ring with an airfoil (streamline) cross section whose center is defined by a flat bottom surface on the same plane and a convex curved surface above. The outer circumferential portion has a small convex lip whose outer circumferential surface has a conical surface tapered by about 45 degrees and whose lower edge slightly protrudes downward from the flat bottom surface. A gliding ring characterized by being integrally formed along the periphery where convex curved surfaces intersect. (2) The glide ring according to claim 1, wherein the supporting bone ring is sandwiched between surface layers near the inner circumference of the ring body. (3) The gliding ring according to claim 1, wherein the surface layer of the outer peripheral portion has dimples formed on its convex surface. (4) Claim 1 of the above utility model registration, characterized in that when the ring body has an outer diameter of about 33.2 cm, the height of the convex lip is about 0.35 cm. Gliding ring described in.
