摘要： A sealing device for performing sealing by a throw off effect of a slinger (2). The sealing device is provided with a stationary sealing element (1) and the slinger (2) to prevent abrasion of an intimate contact slide section (S2) due to dust, muddy water, etc. and further prevent subsequent degradation of sealing ability of the sealing device caused by the abrasion. The stationary sealing element (1) has a thrust lip (12) and a radial lip (13) located on the inner peripheral side of the thrust lip (12) and is installed on a stationary member (101). The slinger (2) has a sleeve (21) fitted on a rotary member (102) and a flange (22) extending from one end of the sleeve (21). The thrust lip (12) is made to be in intimate slidable contact with the flange (22), and the radial lip (13) is made to be in intimate slidable contact with the outer peripheral surface of the sleeve (21). A circumferentially continuous dam (23) is provided on the outer peripheral surface of the sleeve (21) so as to be positioned on the flange (22) side of the intimate contact slide section (S2) of the radial lip (13). The dam (23) is a ridge (231) or a groove.

摘要： Sealing devices (1) in which, when they are stacked in the axial direction, a grease (G) applied to sealing lips (12) and (13) of each sealing device (1) is prevented from coming into contact with and adhering to an attachment ring (11) of an adjacent sealing device (1). The sealing device (1) comprises an attachment ring (11) and, united therewith, sealing lips (12) and (13) made of a rubbery elastic material. It has a projection (17) made of a rubbery elastic material and located along the periphery of the attachment ring (11). When such sealing devices (1) are stacked in the axial direction, the projection (17) serves as a holding part to come into contact with the attachment ring (11) of the adjacent sealing device (1) located on the side which the sealing lips (12) and (13) face, whereby necessary gaps (δ 1 ) and (δ 2 ) are held between the grease (G) applied to the sealing lips (12) and (13) and that adjacent attachment ring (11).

摘要： A sealing device in which squealing noise occurring when a steering shaft is in strong intimate contact with a bumper portion is effectively suppressed and in which a slide member for preventing squealing noise can be easily fixed to the bumper portion. The sealing device (1) for sealing between a housing and a shaft inserted into the housing has a first molding (11) in which the bumper portion (16) and a seal lip portion (17) are integrally molded, with a bellows-like flexible portion (15) in between, on the inner peripheral side of an outer peripheral fixing portion also has a second molding (21) in which a second bumper portion (26) is integrally molded, with a second flexible portion (25) in between, on the inner peripheral side of a second fixing portion (22) secured to the outer peripheral fixing portion (12). Fall out prevention portions (19, 29) are respectively provided on the inner peripheral surfaces of the bumper portion (16) and second bumper portion (26), and resin slide members (20, 30) are fitted without bonding to the fall out prevention portions (19, 29), respectively.
