Summary:PROBLEM TO BE SOLVED: To reduce influences of a radial load Fz and a longitudinal direction load Fx onto a measured value of an axial load Fy, and to realize structure capable of finding precisely the axial load Fy acting between an outer ring 3a and a hub 1a. SOLUTION: An acting direction of the axial load Fy is specified in response to an acceleration sensor, a difference of revolution speeds of rolling elements 8a, 8b in both trains, or the like. The axial load Fy is calculated, based on the revolution speed of the rolling elements 8a, 8a (or 8b, 8b) in the train for supporting the axial load Fy, and based on a rotational speed of the hub 1a. The problem to be solved hereinbefore is solved because the revolution speed of the rolling elements 8a, 8a (or 8b, 8b) in the train for supporting the axial load Fy is hardly fluctuated by the radial load Fz and the longitudinal direction load Fx.
