    Abstract: A rotation transmission device having a high torque measurement resolution is provided. The rotation transmission device is provided with: a rotary-shaft unit (6) having a first and second rotary shaft (13, 14) combined so as to be coaxial and such that the end sections thereof can rotate relative to each other and a torsion bar (15) that is provided on the inner-diameter side of the first and second rotary shafts so as to be coaxial therewith, has one end section connected to the first rotary shaft (13), and has the other end section connected to the second rotary shaft (14); a first gear (7) fastened to the outer peripheral surface of the first rotary shaft (13); a second gear (8) fastened to the outer peripheral surface of the second rotary shaft (14); a coupling shaft (9) provided on the inner-diameter side of the torsion bar (15) so as to be coaxial therewith, having one end section connected to one rotary shaft (13), and having the other end section protruding from an end of the torsion bar (15) in the axial direction; a first encoder disposed and fixed on the other end of the coupling shaft (9) so as to be coaxial with the first rotary shaft (13) and having a first detected section (39); a second encoder fastened on the other end of the second rotary shaft (14) so as to be close to the first encoder and having a second detected section (40); and a sensor unit having at least one sensor (42a, 42b) that faces the first and second detected sections (39, 40).

    Abstract: A vehicle wheel supporting rolling bearing unit includes a stationary side bearing ring member, a rotation side bearing ring member, and plural rolling elements. The rotation side bearing ring member is provided with a first acceleration sensor, a second acceleration sensor, and a third acceleration sensor which are fixed on a virtual plane orthogonal to a center axis of the rotation side bearing ring member. The first acceleration sensor and the second acceleration sensor are arranged on a virtual line passing through a rotation center of the rotation side bearing ring member with a same distance from the rotation center while detection directions thereof are directed in a radial direction and are opposite to each other in the radial direction. The third acceleration sensor is arranged such that a detection direction thereof is non-parallel to the detection directions of the first acceleration sensor and the second acceleration sensor.
