Claims (1)
周に設けられたスプリングの締め付け力により、
回転部材の外周面に圧接させる構造のオイルシー
ルにおいて、 前記リツプとスプリングとの間の外側面が周方
向で凹凸状に形成され、かつ、この凹凸面の凸部
に、前記回転部材の回転方向に対して後方ほど外
側に張り出すテーパ面が形成されていることを特
徴とするオイルシール。[Claim for Utility Model Registration] The lip formed on the inner periphery of the seal body is tightened by the tightening force of a spring provided on the outer periphery of the lip.
In an oil seal configured to be brought into pressure contact with the outer circumferential surface of the rotating member, the outer surface between the lip and the spring is formed in an uneven shape in the circumferential direction, and the convex portion of the uneven surface has a direction in which the rotating member rotates. An oil seal characterized by having a tapered surface that protrudes outward toward the rear.
