SEALING DEVICE

摘要

Provided is a sealing device comprising a stationary-side sealing element (1) mounted in a stationary-side member (101) and having a thrust lip (12), and a slinger (2) having a sleeve (21) fitted in a rotary-side member (102) and a flange (22) extending from one end of the sleeve (21). The thrust lip (12) is held in slidable contact with the flange (22), and an annular rubbery elastic member (3) to be held in close contact with the outer circumference of the rotary-side member (102) is integrated with an end portion (21a) of the sleeve (21) on the opposite side of the flange (22). As a result, it is possible to prevent a leakage or an invasion of a foreign substance reliably through the small clearance of the fitting portion between the sleeve (21) and the rotary-side member (102).
