Abstract:
To provide a bearing device in which a connection part between a preload sensor and a wiring part is less likely to break.SOLUTION: A bearing device 100 comprises: a preload sensor 10 which includes a pressure-sensitive pattern part 22c varying in electric characteristics, such as DC resistance, with pressure acting in an axial direction and a first terminal part 22a and a second terminal part 22b electrically connected to the pressure-sensitive pattern part 22c; and a wiring part 16 which is electrically connected to the first terminal part 22a and second terminal part 22b. The bearing device 100 has, between a plurality of bearings 1a, 1b, a second end face 6b as a first plane crossing the axial direction and an end face 2c as a second plane opposed to the second end face 6b in the axial direction. A first interval region A1 and a second interval region A2 which has a larger interval between the second end face 6b and end face 2c than the first interval region A1 are provided between the second end face 6b and end face 2c. The pressure-sensitive pattern part 22c is arranged in the first interval region A1. A connection part 24 between the first terminal part 22a and second terminal part 22b, and the wiring part 16 is arranged in the second interval region A2.SELECTED DRAWING: Figure 1
