A gasket is equipped with a cylindrically shaped cylindrical part, and a ring part which extends in a radially inward direction from one end section of the cylindrical part in the axial direction thereof. The cylindrical part has a projecting part which projects in a radially inward direction between both end sections thereof in the axial direction. The projecting part has a first angled section positioned on the ring part side thereof, and a second angled section positioned on the side thereof opposite the ring part, and if a sealing body is placed on the ring part, the first angled section is formed so as not to extend beyond the top surface of the flange section of the sealing body.
