特徴とするリツプシール。 It consists of an annular metal case that is hermetically fitted to the inner periphery of the shaft hole of the housing, and a disk-shaped lip member whose outer diameter is hermetically fixed to the case, and whose inner diameter is In a lip seal that prevents leakage of the sealing fluid by slidingly contacting the outer circumferential surface of the rotating shaft with an appropriate interference in a state of bending and projecting toward the sealing fluid side, the lip member is made of two disc-shaped sheets stacked on each other. 1. A lip seal comprising a sheet, characterized in that a required number of spiral notches are formed in the inner diameter portion of the disk-shaped sheet on the side that comes into sliding contact with the outer peripheral surface of a rotating shaft.
