摘要： A rolling bearing with the sealing device which has a fitting groove and sealing device with a mounting portion. The fitting groove formed on the inner peripheral surface of an outer ring. An outside surface of the fitting groove tilts at 5 to 30 degrees with respect to an radial direction of the bearing. An inside surface of the fitting groove tilts at a tilt angle smaller than that of the outside surface. A total of these tilt angles is 35 degrees or more. The mounting portion has a base portion contacting the inside surface and a portion projecting toward the outside surface of the fitting groove from the base portion, and the mounting portion is thinnest at a front end portion of the projecting portion.
