ABSTRACT:
In a rolling bearing providing an inner race, an outer race, a plurality of rolling elements and a sealing plate closing an open end between the outer circumference of the inner race and the inner circumference of the outer race, the sealing plate is formed of a synthetic resin in a generally annular shape, the sealing plate including an annular main plate portion and an engaging rim formed along an outer peripheral edge of the main plate portion, the engaging rim having an outwardly opened groove on its lateral side and being deformable elastically in a radial direction of the rolling bearing to engage the engaging groove. Further, the outwardly opened grooved includes a bottom surface which is positioned between a first plane and a second plane that extend outer and inner surfaces of the main plate portion in the radial direction, respectively. The rolling bearing achieves a structure having high sealing performance to prevent the deformation of sealing plate.
