The gasket clamping mechanism () clamps the gasket () from the axial direction by a gasket-pressing ring () and lower mold ring (). The first mold push-in mechanism () pushes the upper mold () into the gasket () by a gasket push-in member (). The second mold push-in mechanism () includes a plurality of push pins () and pushes up the lower mold () to push it into the gasket ().
