Abstract
A rolling bearing device includes a rolling bearing that includes an outer ring having an inner peripheral surface on which a first raceway surface is provided, an inner ring having an outer peripheral surface on which a second raceway surface is provided, and rolling elements interposed between the first and the second raceway surfaces; a strain sensor configured to detect a strain of the rolling bearing; and a fixation portion configured to fix the strain sensor to a peripheral surface that includes at least one of an outer peripheral surface of the outer ring and an inner peripheral surface of the inner ring. The fixation portion fixes at least two locations in the strain sensor to the peripheral surface such that a detection region of the strain sensor and the peripheral surface are not fixed to each other, the at least two locations facing each other across the detection region.
