Abstract

A gasket capable of suppressing reduction in sealing performance due to an eccentricity of an application target is provided. A sealing device 1 includes an elastic body portion 2 formed from an elastic body. The elastic body portion 2 includes a fitting portion 10 that is an annular part, a lip 20 that is an annular part protruding from the fitting portion 10 to an inner periphery side, and an annular first protruding portion 30. The lip 20 protrudes from an inner end portion 10a of the fitting portion 10 while being inclined to an inner side. A length 1 of the lip 20 in the protruding direction is set based on a minimum crush allowance c when a tube is eccentric at maximum with respect to a through hole. The first protruding portion 30 protrudes from the inner end portion 10a of the fitting portion 10 toward the inner side.
