It has an inner cylindrical surface 31 to be fitted and an outer tapered surface 32 complementary to the tapered surface 22 of the outer ring 12.
The inner ring 13 has a flange portion 33 formed on the larger diameter side of the tapered surface 32. The outer diameter of the flange portion 33 is slightly smaller than the inner diameter of the mounting shaft insertion hole of the rotating body B. The same applies to the outer diameter of the outer ring 12. Code 34
Are a plurality of slits formed in the tapered portion in the axial direction. The slit 34 provides flexibility to the portion where the tapered surface 32 is formed. Note that such a slit 34 can be replaced with one slit formed in the axial direction. Reference numeral 35 is a through hole for the bolt 14.
Reference numeral 35 'denotes a screw hole for screwing a bolt (not shown) for disassembling the fastening device.

Is pressed against the inner circumference of the mounting shaft mounting hole . On the other hand, the inner ring 13 is contracted by the slit 34 and pressed against the outer periphery of the mounting shaft A. At this time, the outer ring 12 moves in the axial direction with respect to the inner ring 13, and the rotating body B also tries to move in the same direction. However, the retaining ring 15 is on the rotating body B side.
Since the rotating body B is in contact with the end face , the rotating body B is prevented from moving in the axial direction. As a result, the rotating body B is positioned with respect to the axis A.
