PROBLEM TO BE SOLVED: To provide structure capable of compensating an axial-directional shift between a detected part provided on an outer circumferential face of an encoder support-fixed onto an inner ring corresponding member, and a detecting part of a sensor supported onto an outer ring corresponding member, irrespective of preload fluctuation. SOLUTION: Both end parts of the encoder 4c are fit around to be fixed by fitting fasteningly both end parts respectively onto a hub main body 18 and an inner ring 19 constituting a hub 2. When an axial-directional shift between the hub main body 18 and the inner ring 19 is generated, based on the preload fluctuation, both end parts of the encoder 4c are displaced along a reverse direction by the shift same thereto.
