PROBLEM TO BE SOLVED: To prevent the seal property of a lip from being deteriorated by suppressing the occurrence of oil sludge by suppressing the temperature elevation of lubricating oil around the lip part.SOLUTION: A rolling bearing includes: a ring-shaped outer ring 21; an inner ring 22 disposed at an inner peripheral side of the outer ring 21; and a rolling body 24 which rolls between the outer ring 21 and the inner ring 22. In a rotary shaft device, the outer ring 21 is fitted to a housing 11, the inner ring 22 is fitted to a rotary shaft 40, a companion flange 50 is connected rotatable to the rotary shaft 40, an oil seal 60 is mounted to the inner periphery of the outer ring 21, and a lip 64 at an inner peripheral side of the oil seal 60 is brought into slide-contact. A slinger 70 is formed of a metallic plate and includes a fitting part 74 fitted to either the inner ring 22 or the companion flange 50, a slide contact part 72 with which the lip 64 of the oil seal 60 is brought into slide contact, and an erection part 73 which extends in a radial direction to connect the fitting part 74 and the slide contact part 72. |
