Zusammenfassung:	To reduce friction between a seal ring and a mating member contacting the seal ring.SOLUTION: A seal ring 10A includes a slide part 11, a groove bottom part 12, a compression side face 13, and a non-compression side face 14, the non-compression side face 14 being located on the seal ring 10A at its opposite side to the compression side face 13, the groove bottom part 12 including an inclined surface 16 inclined to a center line O of the seal ring 10A. The seal ring 10A has a protruded part 15 protruded from the non-compression side face 14. The inclined surface 16 is inclined so that an end 16b of the inclined surface 16 farther from the compression side face 13 is located closer to the slide part 11 than an end 16a closer to the compression side face 13.SELECTED DRAWING: Figure 3 【課題】シールリングとこのシールリングと接触する相手側の部材との間のフリクションを低減する。【解決手段】シールリング１０Ａは、摺動部１１、溝底部１２、加圧側面１３及び非加圧側面１４を有する。非加圧側面１４は、シールリング１０Ａにおいて加圧側面１３とは反対側に位置する。溝底部１２は、シールリング１０Ａの中心線Ｏに対して傾斜する傾斜面１６を含む。シールリング１０Ａは、非加圧側面１４から張り出す凸部１５を有する。傾斜面１６は、傾斜面１６の加圧側面１３から遠い方の端部１６ｂが、加圧側面１３に近い方の端部１６ａよりも、摺動部１１の近くに位置するように傾斜する。【選択図】図３
