<P>PROBLEM TO BE SOLVED: To convert a variable physical amount correlated to a variation parameter for determining a relative position into a signal by a sensor while increasing interference of an inner ring of a tapered hole and more exactly obtain the variation parameter by arithmetic operation using the measured value of the variable physical amount and inputted information. Ž<P>SOLUTION: A bearing mounting auxiliary device includes a sensor installation part 11d recessed at an axis side between a mutually fitting surface 11a at an axis 2 side and a male screw 11b of an outer diameter surface of an adapter sleeve 11. When a fitting position is relatively moved while the sensor 12 is interposed between the mutually fitting surface 1b of the inner ring 1 and the sensor installation part 11d, the sensor 12 sends an electric signal allowing the contact pressure of the mutually fitting surfaces 1b, 11a to be converted as the variable physical amount to an arithmetic element 13. The arithmetic element 13 obtains the interference of the inner ring 1 or the like and displays it by an arithmetic operation using correlation between the contact pressure of the mutually fitting surfaces 1b, 11a, and the actually generated interference of the inner ring 1 and an inner clearance.
