<P>PROBLEM TO BE SOLVED: To provide a rolling bearing preventing deterioration of sealing performance by adjusting pushing force of a lip part to a rotation side raceway ring. <P>SOLUTION: The rolling bearing 31 is provided with an inner ring 32 as the rotating side raceway ring; an outer ring 33 as a non-rotation side raceway ring; a plurality of tapered rollers 34 as rolling elements arranged between the inner ring 32 and the outer ring 33; and a sealing seal 36 as the sealing member including an annular lip part 36d abutted to the inner ring 32, and a ring part 36c adjusting the pushing force of the lip part 36d to the inner ring 32, and fixed by the outer ring 33. The ring part 36c includes a first ring formed by shape-memory alloy. The first ring extends a diameter when a temperature exceeds a shape recovery temperature. <P>COPYRIGHT: (C)2008,JPO&INPIT |
