ろがり軸受。[Claims for Utility Model Registration] A sealed type roller in which a peripheral bent portion of a metal seal plate is attached to a circumferential groove of an outer ring to seal grease into an area surrounded by the outer ring, inner ring, and seal plate where the rolling elements exist. In the bearing, the circumferential groove of the outer ring has a shape that accommodates the seal plate with a gap on the outside in the radial direction, and the circumferential bent part of the seal plate is attached to the end of the outer ring in a substantially axial direction of the outer ring. A sealed rolling bearing characterized in that a peripheral protrusion that presses inward is formed, and a chamfered portion starting from at least the center position of the peripheral groove is formed on the outer peripheral surface of the outer ring.
