    摘要: A seal device provided with a sealing flange and a sealing lip in slidable contact with the sealing flange, wherein the occurrence of still leakage is suppressed when a rotating shaft stops rotating. To achieve this purpose, the invention provides a seal device for sealing the space between a housing and a rotating shaft inserted through a shaft hole provided in the housing to prevent a sealed fluid inside the device from leaking out of the device, a sealing lip fitted to the inner periphery of the shaft hole of the housing being in slidable contact with the entire periphery of a sealing flange fitted to the outer periphery of the rotating shaft; and the seal device being characterized in that a screw groove is provided for exerting a fluid pumping action when the rotating shaft rotates, and the screw groove is provided to a position where the screw groove does not cross the contact area in which the sealing lip is in slidable contact with the entire periphery of the sealing flange.

    摘要: The invention pertains to a sealing device (1) comprising a seal flange (13) and a seal lip (24) configured to slidably come into contact with the seal flange (13). A facing surface of the seal lip (24) facing to a machine outer side end face of the seal flange (13) is provided with a thread groove (33) configured to exert an action of pushing back a sealed fluid toward a machine inner side (A) by exerting a pumping action caused by a centrifugal force when a rotating shaft (61) rotates.
