Abstract
A tapered surface is formed at each axially outer end portion of an inner circumferential surface of a gasket such that a diameter thereof gradually increases from an axially inner side toward an axially outer end thereof in a state before an annular primary sealing portion of the gasket is press-fitted into an annular primary sealing groove of a fluid device. A diameter increase starting point of the tapered surface is located in a range from a deformation starting point position serving as a starting point from which the inner circumferential surface is deformed due to the primary sealing portion receiving external force form the fluid device when the primary sealing portion is press-fitted into the primary sealing groove, to a center position in an axial direction of the inner circumferential surface.
