In a rolling bearing having a sealing plate provided with first and second contact lips that are in sliding contact with the inner and outer walls of the inner ring, respectively, the inner peripheral edge of the sealing plate has a thin-walled portion that sinks into the circumferential groove of the inner ring, and a thin-walled portion that extends from the thin-walled portion to the circumference. A sealing device for a rolling bearing, characterized in that a first thick-walled lip that slides in contact with the inner sidewall of the groove and a second thick-walled lip that slides in contact with the outer sidewall of the circumferential groove are sequentially formed in the radial direction. . (2) The outer circumferential edge is fitted into a circumferential groove formed on the inner diameter side end of the outer ring, and the lip of the inner circumferential edge slides into the inner and outer walls of the circumferential groove formed at corresponding positions on the outer diameter surface of the inner ring. 1. In a rolling bearing having a second contact lip, the outer end of the circumferential groove of the inner ring is formed by a circumferential step portion with a small diameter, and the tip extends diagonally inward toward the outer diameter surface of the inner ring, and is connected to the outer diameter surface. a first non-contact lip that faces each other with a slight gap; a thin wall portion that extends perpendicularly into the circumferential groove of the inner ring from the first non-contact lip and sinks into the circumferential groove; A first thick-walled lip that slides on the side wall and a second thick-walled lip that slides on the outer sidewall of the circumferential groove are sequentially formed in the radial direction, and a slight gap is formed with the small-diameter circumferential step of the inner ring. A sealing device for a rolling bearing, characterized in that second non-contact lips facing each other extend from a thin walled portion.
