Claims (1)
ベローズを介して気密担持され、ゴムベローズの
両端フランジ間にスプリングホルダを介して装着
したコイルスプリングで軸方向に付勢されて軸方
向メイテイングリングと密接摺動する構造のメカ
ニカルシールにおいて、上記スプリングホルダの
内径筒状部の切断縁が、ゴムベローズの撓み部表
面から離反する方向に屈曲してなることを特徴と
するメカニカルシール。 The seal ring is airtightly supported inside the cartridge case via a rubber bellows, and is urged in the axial direction by a coil spring installed between the flanges at both ends of the rubber bellows via a spring holder, so that it slides closely against the mating ring in the axial direction. A mechanical seal having a movable structure, wherein the cut edge of the inner diameter cylindrical portion of the spring holder is bent in a direction away from the surface of the flexible portion of the rubber bellows.
