<P>PROBLEM TO BE SOLVED: To provide a bearing, capable of maintaining a smooth rotation of a shaft, even if a rolling bearing part supporting the shaft is in failure. <P>SOLUTION: The bearing includes: an outer ring 20 which is accommodated in an accommodating part 33 provided with a housing 30 and includes a hollow part 24; and the rolling bearing part 10 which is fitted to the hollow part 24 and rotatably supports the shaft 1. The outer ring 20 rotates with respect to the housing 30 when friction torque on the rolling bearing part 10 exceeds static friction torque between the outer ring and the housing. In particular, the housing 30 has an oil filling port 31 opening on the accommodating part 33; the outer ring 20 has a projection 21 projecting outward; and the projection 21 has a close-contact part 25 for making close-contact with the surrounding of the oil filling port 31. <P>COPYRIGHT: (C)2012,JPO&INPIT |
