PROBLEM TO BE SOLVED: To provide a seal structure of a slewing bearing by which it can be visually confirmed whether or not a seal member is assembled while inclining to inner/outer rings, and the slewing bearing.SOLUTION: This seal structure is employed to a slewing bearing having elastic-body made seal members 7A, 7B which seal an axial end of a bearing space 6 between an inner ring 1 and an outer ring 2. Each of the seal members 7A, 7B has a base part 20 which is held to one bearing ring 2 out of the inner ring 1 and the outer ring 2, and three seal lips 21, 22 and 23 which extend from the base part 20 toward the other bearing ring 1 out of the inner ring 1 and the outer ring 2 in different orientations. The two seal lips 21, 22 which are close to at least the bearing space 6 out of the three seal lips contact with a peripheral face 1a which opposes the other bearing ring 1. The seal lip 23 which is farthest from the bearing ring 6 is formed into a shape at which it can be visually confirmed whether or not the seal member 7A is in a properly-assembled state.SELECTED DRAWING: Figure 1 |
