Claims

[Claims for Utility Model Registration] 1. A seal body 10 that is fitted onto one of the circumferential surfaces of the inner race 3 or outer race 5 of the bearing 1, and a sealing slide that extends radially from the seal body 10 and connects to the other circumferential surface. In a bearing sealing member comprising a seal lip portion 20 made of an elastic material that moves,
It is composed of a first seal lip 21 located at the inner side Y of the bearing and a second seal lip 25 located at the inner side Y of the bearing. , 26 and a second inclined surface 23 inclined toward the inside of the bearing.
, 27 intersect with each other, and the angle α between the first inclined surface and the race peripheral surface is equal to the angle β between the second inclined surface and the race peripheral surface. The second sealing lip 25 has an axial recess 29 on the side of the first inclined surface, and the second sealing lip 25 has an axial recess 29 on the side of the first inclined surface.
An annular spring member 30 is arranged on the peripheral surface opposite to 8,
The spring member is located inside the bearing in the axial direction compared to the sealing surface 28, and the dust strip 32 extending from the seal body 10 toward the atmosphere in the axial direction is aligned with the outer peripheral surface of the member 36 extending from the inner race side. A sealing member for bearings that covers the entire part. 2. The first seal lip 21 has an annular spring member 19 on the peripheral surface opposite to the seal surface 24, and
Spring mounting groove 1 into which the annular spring member 19 is mounted
8 is an inclined surface 17 facing the second seal lip 25 side.
A bearing sealing member according to claim 1, comprising:
