Claims

[Scope of Claim for Utility Model Registration] In a piston ring with an interrupted undercut/tapered face type in which an undercut is applied to the lower part of the outer circumferential surface while leaving a portion near the abutment of the piston ring, the outer circumferential surface of the undercut portion. Below the extension line of the lower edge,
With undercut. The outer circumferential surface of the uncut portion is cut to a size that is much smaller than the cut amount of the undercut portion, and a projecting edge is formed between the outer circumferential surface and the cut surface, so that the contact point to the cylinder liner is at the lower end. A piston ring characterized in that it has a rim and a flange.
