The member extends obliquely from the base toward the inner circumferential surface of the cylinder bore in a direction in which a base portion that fits into the outer circumferential groove and a distal end portion approach and oppose each other, and the distal end portion extends obliquely toward the inner circumferential surface of the cylinder bore. A seal structure for an accumulator, characterized in that it has a structure in which two lip portions that come into sliding contact are integrally formed.
