Abstract

Official abstract text for this publication.

A thrust bearing that can improve the effect of preventing entry of muddy water etc. The thrust bearing includes: an annular first bearing ring; an annular second bearing ring facing the first bearing ring in an axial direction; a plurality of rolling elements rollably arranged between the first bearing ring and the second bearing ring; an outer seal provided on the second bearing ring, located radially outward of the rolling elements, and sealing a space between the first bearing ring and the second bearing ring; and a cover covering the outer seal from outside in a radial direction.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A thrust bearing comprising: an annular first bearing ring; an annular second bearing ring facing the first bearing ring in an axial direction; a plurality of rolling elements rollably arranged between the first bearing ring and the second bearing ring; an outer seal provided on the second bearing ring, located radially outward of the rolling elements, and sealing a space between the first bearing ring and the second bearing ring; and a cover covering the outer seal from outside in a radial direction, wherein: the cover includes an inner cylindrical portion extending in the axial direction on a radially outer side of the outer seal between a first mount member to which the first bearing ring is attached and a second mount member to which the second bearing ring is attached; an inner annular portion extending outward in the radial direction perpendicular to the axial direction from an end of the inner cylindrical portion on the side of the first mount member; an outer cylindrical portion connected to a radially outer end of the inner annular portion and extending toward the first mount member; and an outer annular portion connected to an end on the one side in the axial direction of the outer cylindrical portion on the side of the first mount member and extending outward in the radial direction. 2 . The thrust bearing according to claim 1 , wherein the cover includes a support portion that contacts an outer peripheral surface of the outer seal and presses the outer seal from the outside in the radial direction. 3 . The thrust bearing according to claim 1 , wherein there is a space among the cover, the outer seal, and the first mount member.
