摘要： PROBLEM TO BE SOLVED: To provide a piston ring for reducing the amount of gas to leak through a closed gap for a long period.
SOLUTION: A top ring 21 to be mounted on the outer periphery groove of a piston for an internal combustion engine prevents the leakage of combustion gas or exhaust gas form a combustion chamber into a bore of a cylinder 11. It functions as a compression ring for preventing the leakage of oil or blow-by gas from the bore of the cylinder 11 into the combustion chamber. Abutment joints (gaps) are formed at both ends of the top ring 21. Insertion holes 21d, 21e are formed in joint surfaces 21a, 21b facing each other with the closed gap therebetween. A resin member 30 has protruded portions 30d, 30e to be inserted into the insertion holes 21d, 21e and a protruded portion 30a for abutting on a cylinder inner wall 11a.
