。[Claims for Utility Model Registration] A bearing equipped with a seal ring that is fixed to an outer ring of a bearing and forms a non-contact seal structure and a contact seal structure with a circumferential step provided on a shoulder of an inner ring of the bearing. In the sealing device, the seal ring body includes: an annular portion provided to close an axial gap between the outer ring and the inner ring; and an annular portion extending toward the center in the radial direction of the annular portion; While forming a small gap with the side of the
A small gap is provided between a main lip having a predetermined flexibility and an outer circumferential surface of the inner ring that protrudes inward of the bearing along the outer circumferential surface of the inner ring and that is continuous with the small gap. an auxiliary lip that forms a gap; an annular convex portion that is provided on the radially center side of the main lip and that lightly contacts the side surface of the circumferential step while facing the outer circumferential surface of the circumferential step; and the annular portion. an annular first mandrel provided on the inner ring, and a separate member from the first mandrel, which is provided so as to span over a part of the main lip from the inner peripheral surface of the auxiliary lip facing the outer peripheral surface of the inner ring. 1. A bearing sealing device comprising: a ring-shaped second core metal;
