Claims (1)
フト外周の間をゴムベローズで気密保持してなる
回転型メカニカルシールにおいて、前記ゴムベロ
ーズの内径筒状部の外周溝に嵌着されてシヤフト
に対する該内径筒状部の緊迫力をバツクアツプし
てなるドライブリングの後端に、前記内径筒状部
の後端部外周に接触したカバー部を突設してなる
ことを特徴とする回転型メカニカルシール。 In a rotary mechanical seal in which a rubber bellows maintains airtightness between a rotating ring axially biased by a spring and the outer periphery of the shaft, the rubber bellows is fitted into an outer circumferential groove of an inner cylindrical portion to provide a contact with the shaft. 1. A rotary mechanical seal characterized in that a cover portion that contacts the outer periphery of the rear end of the inner cylindrical portion protrudes from the rear end of a drive ring that backs up the tension force of the inner cylindrical portion.
