发明名称 BEARING SEALING DEVICE, AND BEARING ADAPTED FOR USE IN WHEEL AND USING THE BEARING SEALING DEVICE
摘要 <p>Provided are a bearing sealing device having enhanced resistance to muddy water and having a reduced cross-sectional height, and a bearing adapted for use in a wheel and using the bearing sealing device. The bearing sealing device (1) is placed between relatively rotating inner and outer members of a bearing for a wheel and has an annular seal plate (2) and an elastic seal member (3).The seal plate (2) is made up of a circular tube section (2a) fitted on the outer periphery of the inner member and also of a vertical plate section (2b) rising from an end of the circular tube section (2a), and the seal plate (2) has an L-shaped cross-section. The elastic seal member (3) is formed by securing an elastic body (5) to a core (4). The core (4) is made up of a circular tube section (4a) fitted in the inner periphery of the outer member and also of a vertical plate section (4b) hanging down from an end of the circular tube section (4a), and the core (4) has a reverse L-shaped cross-section facing the seal plate (2). The elastic body (5) has two side-lips (5a, 5b) arranged next to each other in the radial direction of the core (4) and having tips in contact with the vertical plate section (2b) of the seal plate (2). The distance between the side lips (5a, 5b) is not less than 0.1 mm.</p>
