Abstract:
1. A sealing device for sealing an annular gap between a housing having a shaft hole and a shaft inserted into the shaft hole for preventing leaking of a fluid on one side in an axial direction to another side in the axial direction, the sealing device comprising: a first sealing member made of a rubber-like elastomer comprising a body and a sealing lip, the sealing lip extending toward the one side in the axial direction from the body and being in slidable contact with an outer peripheral surface of the shaft; a second sealing member made of resin being in slidable contact with the outer peripheral surface of the shaft at a position further to the other side in the axial direction from a position where the first sealing member is in contact with the outer peripheral surface of the shaft; a positioning member being in contact with an end face on the one side of the body in the axial direction and including a positioning portion for positioning the first sealing member in the axial direction; and a case retaining the first sealing member, the second sealing member, and the positioning member, wherein the positioning member includes a bent portion on the one side of an inner peripheral end portion of the positioning portion in the axial direction, an edge portion at a tip of the bent portion being bent toward an outer peripheral side so as to be spaced apart from an outer peripheral surface of the sealing lip, a contacting portion of the bent portion positioned further to an inner peripheral side from the tip being in surface contact with the outer peripheral surface of the sealing lip.
