PROBLEM TO BE SOLVED: To realize a structure for accurately finding the load applied to a wheel supporting ball bearing unit 1 in various directions. SOLUTION: Relative displacements are measured between an outer wheel 3 and a hub 4 in the radial and axial directions. A calculator calculates the load acting between the outer wheel 3 and the hub 4, based on measurement values regarding the relative displacements. Especially, this calculator takes into consideration the influence coefficients, and finds load components applied between the outer wheel 3 and the hub 4 in plural directions, based on the relative displacements between the outer wheel 3 and the hub 4.
