Claims

[Scope of utility model registration request]

Two piston rings are attached axially overlapping each other in the ring groove closest to the combustion chamber of the piston, which reciprocates while sliding on the inner periphery of the cylinder, and a backup ring is attached so as to make contact with the inner periphery of both rings. In the interposed piston ring device for an internal combustion engine, a small portion of the two piston rings (both at the joint part of one ring, in particular, the sliding surface with the cylinder wall and the contact surface with the other ring) 1. A piston ring device for an internal combustion engine, comprising a protrusion and a recess formed at the other end to receive the protrusion so as to be in close contact with the protrusion.
