| description | Provided is a combined oil ring (10) in which carbon sludge and the like are not deposited between side rails (11) and a spacer expander (12) even if an internal combustion engine is operated for a long period of time. The combined oil ring is configured to be fitted in an oil ring groove (3) of a piston (2), and includes: a pair of upper and lower plate-like circular side rails (11); and a spacer expander (12) arranged between the pair of side rails (11). The spacer expander (12) includes: a large number of upper pieces (13) and lower pieces (14) that are alternately arranged in a circumferential direction so as to be spaced apart in an axial direction and the circumferential direction; coupling pieces (15) that respectively couple the adjacent upper pieces (13) and lower pieces (14); and ear parts (16) that are each formed so as to erect in an inner circumferential end portion of each of the upper pieces (13) and the lower pieces (14), and serve to push the side rails. |
