Abstract
The present invention addresses the problem of providing a method for measuring axial clearance of a wheel bearing device, with which it is possible to make a high-precision measurement of negative axial clearance. This method comprises: a step (S02) for press-fitting an inner race (4); a first negative axial clearance measurement step (S03); a swaging step (S04); an inner-race press-in amount measurement step (S05); a first inner-race outer-diameter increment measurement step (S06); a second inner-race outer-diameter increment calculation step (S07); an outer-diameter increment difference calculation step (S08); a first axial clearance decrement calculation step (S09); a second axial clearance decrement calculation step (S10); a third axial clearance decrement calculation step (S11); and a second negative axial clearance calculation step (S12).
