<P>PROBLEM TO BE SOLVED: To provide a rolling bearing which prevents the fall of a seal member and excessive sliding resistance by enabling the pressure regulation of releasing air to or introducing air from the outside on the increase and decrease of the inner pressure of a bearing when molding. <P>SOLUTION: The rolling bearing 10 includes a pair of seal members 20a, 20b provided with seal lips 23a, 23b respectively, which slidably contact seal grooves 12b, 12c provided on an inner ring 12. The seal slip 23a of one seal member 20a is pressed toward the center sidewall face 12e in the axial direction of the seal groove 12b, while the seal lip 23b of the other seal member 20b is pressed toward the outer sidewall face 12f in the axial direction of the seal groove. <P>COPYRIGHT: (C)2010,JPO&INPIT |
