PROBLEM TO BE SOLVED: To improve seal performance under a particular environment, in a rolling bearing. SOLUTION: This rolling bearing 5, sealing inner/out rings 9, 10 with a lubricant to be set up in a form of one shaft end side facing a vacuum space A, is used with a pressure resistance seal 6 maintaining a degree of vacuum of the vacuum space in a shaft end in a vacuum space side, so as to improve seal performance under a particular environment by this pressure resistance seal. Here, the inner/outer rings are formed of anticorrosion material.
