One end of each shrunk tubular portions is connected to the circular tubular body, and the other end of the shrunk tubular portion has one side surface extruded into a recessed portion and the other side surface retains the shape of the circuit tubular body and the shrunk tubular portion. The sealing portion is located at a central axis of the tubular body.
