Abstract:
A piston ring includes an annular body having: an inner circumferential surface and an outer circumferential surface; one side surface and the other side surface substantially orthogonal to the inner circumferential surface; and a pair of joint ends. The outer circumferential surface includes an inclined surface and an abutment surface. In a direction connecting the one side surface and the other side surface, a maximum width W 1  of the abutment surface at the joint end is 80% to 150% of a maximum width W 2  of the abutment surface in a portion other than the joint end. In the body, a two-axis difference (d 2 −d 1 ) between a diameter d 1  in a first axis direction passing through a central position of the joint and a diameter d 2  in a second axis direction orthogonal to the first axis direction is greater than −0.25 mm and less than +0.36 mm.

Claim (Index 16):
The piston ring according to  claim 1 , wherein, when the central position of the joint section is set to be 0\u00b0 and the position of the body is represented by an angle,\n the abutment surface at one of the joint ends is a portion positioned in a range of 0\u00b0 to 15\u00b0, \n the abutment surface at the other of the joint ends is a portion positioned in a range of 345\u00b0 to 360\u00b0, and \n the abutment surface in a portion other than the joint ends is a portion positioned in a range greater than 15\u00b0 and less than 345\u00b0.
