The present invention can improve durability of a seal ring even under environments in which the seal ring slides and is supplied with high-pressure hydraulic fluid. A seal ring 40 is an annular seal ring 40 which is configured to be interposed between first and second members 20 and 24, and seals a gap between the first and second members 20 and 24. The second member 24 is inserted into the first member 20, and reciprocates in its axial direction with respect to the first member 20. The seal ring 40 includes an annular base part 70, an annular innermost end part 72, and a widening protrusion part 74. The annular base part 70 has a radially exterior end to contact the first member 20. The annular innermost end part 72 is integrally formed with a radially interior end of the base part 70 to contact the second member 24. The widening protrusion part 74 is integrally formed with the innermost end part 72, and protrudes with respect to the base part 70 in the axial direction of the second member 24.
