Claims

[Scope of utility model registration request]

a housing 7 and a shaft 10 extending through the housing 7;
A damper seal for high pressure that prevents fluid from leaking from the high pressure side A to the low pressure side B. A metal reinforcing ring 6 extending from an outer circumferential part 4 to an inner circumferential part 5 is embedded in an annular main body 2 made of a rubber-like elastic material exhibiting a cross-sectional path shape, and the outer circumferential part 4 is formed on the side surface of a housing 7. The main lip 9 of the inner circumferential portion 5 is fitted into the shaft 10, and the second annular recess 8 extending toward the high pressure side A of the outer circumferential portion 4 is fitted into the circumferential surface of the first annular recess 8 which opens to the high pressure side A of the outer circumferential portion 4. A second seal body 3 made of a resin material and having a 1/2-shaped cross section is fitted into a second annular recess formed by the outer circumferential lip portion 11 of the fork and the high-pressure side side surface 12 of the annular body 2. A high-pressure damper seal characterized in that the main lip 9 is located on the low-pressure side B rather than the sub-lip 14 of the second seal body 3.
