<p><P>PROBLEM TO BE SOLVED: To provide a sealing structure for a turning bearing, capable of effectively preventing the leak-out of grease sealed in a bearing inside space. <P>SOLUTION: The turning bearing includes an inner ring 1 and an outer ring 2 as bearing rings, a plurality of rolling elements 3, and a pair of elastic-material seal members 12 for sealing both axial ends of the bearing inside space 5, respectively. For example, the inner ring 1 is one bearing ring, and the outer ring 2 is the other bearing ring. The seal member 12 has a base part 12a fixed to the inner ring 1, extends from the base part 12a toward the outer ring 2, and has a seal lip part 12c at the tip, contacting a first contacted face 11a formed by the face of the outer ring 2 across the axial direction. The outer ring 2 is provided with a second contacted face 11b formed of a peripheral face extending from the end on the opposite side to one bearing ring in the first contacted face 11a, to the outside in the axial direction. The seal lip part 12 being deflected to the outside in the axial direction contacts the second contacted face 11b. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
