out preventing member is fixed at an end portion of each of the connection ports. Anoutside cylindrical portion of each of the fall-out preventing members has a taperedsurface adapted to enable the fall-out preventing members to be press-fitted onto therespective connection ports, and includes a plurality of engaging portions that areengaged with the engaging groove formed around the axial line on the outsidecircumferential surface of each of the connection ports as the fall-out preventingmembers are press-fitted thereon. And an inside cylindrical portion of each of the fall-out preventing members extends toward a center of the connection ports in an inclinedmanner, and includes a plurality of fall-out stoppers whose tip ends are shaped so as tobe engaged in a groove portion formed around an axial line on the outside
