摘要:
To prevent side rails and a spacer expander of a combination oil ring from sticking to each other. A combination oil ring (10) includes a pair of upper and lower side rails (11, 12) and a spacer expander (13) arranged therebetween, the spacer expander (13) including a plurality of upper pieces (14) and lower pieces (15) alternately arranged in a circumferential direction with the pieces axially and circumferentially apart from each other, a coupling piece (16) coupling an upper piece (14) and a lower piece (15) adjacent to each other, and flange portions (17, 18) formed standing at inner circumferential-side end portions of the upper pieces (14) and the lower pieces (15) so as to press the side rails (11, 12), and a through hole (19) being formed in the flange portions (17, 18), wherein side rail support portions (14a, 15a) that project axially are formed at portions in the circumferential direction of outer circumferential-side end portions of the upper pieces (14) and the lower pieces (15) of the spacer expander (13).
