イルリング。 A pair of side rails arranged above and below whose outer peripheral surfaces can slide into cylinder bore, an expander that urges the side rails toward the cylinder bore and the upper and lower surfaces of the oil ring groove of the piston, and an oil ring on the inner peripheral side of the expander. It is provided between the groove bottom of the groove, extends continuously over substantially the entire circumferential circumference of the piston, and extends in the piston circumferential direction when the thrust and anti-thrust side parts of the piston are contracted in the piston radial direction. A combination oil ring characterized by having a ring member configured as a spring portion that extends in the radial direction of the piston when contracted in the circumferential direction.
