摘要： PROBLEM TO BE SOLVED: To provide a sealing device including a pressure accumulation opening function.
SOLUTION: This sealing device is constituted by combining a seal ring and a buckling. The buckling is constituted of a lip packing including an inner peripheral lip and an outer peripheral lip at one end part of an axial direction of an annular base part and an annular projection for setting a radial direction squeeze margin to the buckling on an outer peripheral surface of the annular base part. The outer peripheral lip includes a function for sealing a sealing fluid by closely coming contact with a cylinder and separating from the cylinder by being pushed by pressure when a pressure accumulation phenomenon is generated in an axial direction other space to open pressure accumulation. The annular projection includes a flow passage for introducing pressure accumulation to the outer peripheral lip.
