PROBLEM TO BE SOLVED: To improve seal robust performance by high surface pressure, and to obtain a low reaction force, in a gasket composed of a rubber elastic material.SOLUTION: A gasket 1 comprises: a base part 11 held to an attachment groove formed at a second member which opposes a first member, and tightly contacting with a bottom face of the attachment groove; and an overhanging part 12 which hangs out to internal/external peripheries from a tip of the base part 11 protruding from the attachment groove, and is sandwiched between the first member and the second member. In the gasket, a main lip 13 is formed at an opposing face opposing the first member of the base part 11, and a first sub-lip 15 is formed at an opposing face opposing the first member of the hanging part 12. A second sub-lip 16 is formed at an opposing face opposing the second member of the hanging part 12, and the second sub-lip 16 is displaced in the width direction with respect to the first sub-lip 15. |
