PROBLEM TO BE SOLVED: To make, for example, the utilization to a shaft seal structure part in a hydraulic buffer most suitable, by that a seal can display a prescribed seal function perfectly when a seal whose outer periphery is closely contacted with the inner periphery of the opening end side of a cylinder body is stored in a seal storing part formed in the outer periphery side of a bearing main body formed by press working. SOLUTION: The diameter direction section of a seal storing part S formed on the outer periphery of a bearing main body 10 for shaft sealing the opening end side of a cylinder body 3 is composed by being set to a trapezoid whose lower side is a short side and upper side is long side and also outer periphery side is a vertical side and inner periphery side is a down slope side heading for an outer periphery side and also the diameter direction section of a seal 4, stored in a seal storing part S, whose outer periphery is closely contacted to the inner periphery of the opening end side of the cylinder body 3 is composed by being set to a shape which nearly coincides with the diameter direction section of the seal storing part S. |
