PROBLEM TO BE SOLVED: To ensure the detection of revolving speed by both revolving speed detecting sensors 20 and 20b regardless of a change in detection clearance between the detection parts of the revolving speed detecting sensors 20a and 20b and revolving speed detecting encoders 23a and 23b based on an axial load applied in both directions, and to prevent the mutual rubbing between both the revolving speed detecting sensors 20a and 20b and both the revolving speed detecting encoders 23a and 23b. SOLUTION: In this load measuring device for rolling bearing unit, the detection clearance L<SB>A</SB>for the outer line which is narrowed in application of a large axial load is set larger than the detection clearance L<SB>B</SB>for the inner line which is narrowed in application of a small axial load, and the minimum values of both the detection clearances L<SB>A</SB>and L<SB>B</SB>are set equal to each other, so that the width of distribution between both the detection clearances is narrowed. According to this, the setting of both the detection clearances is facilitated to solve the problem. COPYRIGHT: (C)2005,JPO&NCIPI
