<P>PROBLEM TO BE SOLVED: To stably prevent creep of an inner ring although fitting work of the inner ring to a rotary shaft is simple. <P>SOLUTION: This bearing device is structured such that the inner ring 1 is clearance-fitted to the rotary shaft 5; the rotary shaft 5 rolls on a fitting surface 1a of the inner ring 1 while contacting the fitting surface 1a in a state rotating around its axis; and the rolling shaft 5, a cross-sectionally wedge-shaped part C1 and the like of the fitting surface 1a of the inner ring 1 are connected to one another. By the connection, the inner ring 1 is synchronized with the rotary shaft 5, and creep of the inner ring is prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT |
