軸受。 A rolling element is provided between the inner ring and the outer ring, and the sealing plate is elastically fixed to a circumferential groove formed on the peripheral surface of the end face of the ring on one side of the ring. In the sealed rolling bearing, the circumferential groove of one of the bearing rings has a substantially U-shaped cross section, and has a radial inner wall, a continuous peripheral wall, and a continuous outer wall. The elastic fixing part of the sealing plate fixed to the circumferential groove is fixed to the circumferential groove, and the width B from the bottom wall to the circumferential edge of the elastic fixing part is equal to the width of the circumferential wall of the circumferential groove. A sealed rolling bearing characterized by having a width smaller than A.
