Abstract
PURPOSE: To secure the sealing performance of the lip section with a limited pressure force through an inward springing of a circular convex part provided on the high pressure side of the lip pressed against on the circumference of the shaft with an elastic pressure receiving material.
CONSTITUTION: This pressure proofing seal for sealing between the high pressure side 1 and the low pressure side 2 at the shaft-pierced section has a circular lip section 11 sealed on the shaft 3 and a circular section 12 to be fastened to the shaft hole 4. A circular convex part 15 is formed on the high pressure side 1 of the lip section 11 having a clearance 14 with the shaft. The convex part 15 is provided on the circumference between a pressure receiving member 17 having a engaging section 13 in such a manner that one end thereof tightly engages thereof while the other end forms an adhesion part 16 which is adapted to adhere tightly on the inner surface of the fastening section 12. Here, the engaging section 13 is made of a synthetic rubber material slightly elastic in the diametrical way. It relatively applies an inward force on the convex part and acts as an auxiliary contact force to the shaft of the lip section 11.
