Abstract

The present invention prevents anchoring between a space expander and a side rail of a combination oil ring. A combination oil ring (10) is provided with a vertical pair of side rails (11 12) and a space expander (13) arranged therebetween the space expander (13) includes a plurality of upper pieces (14) and lower pieces (15) alternately arranged in the peripheral direction and spaced apart in the axial direction and the peripheral direction a coupling piece (16) coupling the adjacent upper pieces (14) and lower pieces (15) and flange sections (17 18) that press against the side rails (11 12) and are formed upright on an inner peripheral side end of the upper pieces (14) and the lower pieces (15) and a through hole (19) is formed in the flange sections (17 18) wherein side rail supporters (14a 15a) which project out in the axial direction are formed at one portion in the peripheral direction of the outer peripheral side end of the upper pieces (14) and the lower pieces (15) of the space expander (13).
