PROBLEM TO BE SOLVED: To provide a bearing supporting structure for measuring bearing load with which the number of ultrasonic probes to be fitted can be kept to be the irreducible minimum when measurement of the bearing load is carried out with the ultrasonic probes. SOLUTION: In the bearing supporting structure for measuring the bearing load, the ultrasonic probes 3 fitted to a bearing housing 1 for supporting the bearings 2 generate incident lights towards the bearing outer ring 20 of the bearing 2 and the reflected wave from the border point between the bearing housing 1 and the bearing outer ring 20 is measured, thus the bearing load is measured. The bearing housing 1 is provided with a fitting hole for fitting the bearing outer ring 20, and a gel-like substance is, as a fitter, laid between the fitting hole and the bearing outer ring 20.
