PROBLEM TO BE SOLVED: To provide a torque sensor which measures torque and thrust.SOLUTION: A torque sensor (100) includes a center section (2), an annular section (3), beam sections (41-44), strain sensors (51-58), bridge circuits (BrA, BrB), and determination means (90). A first beam section (41) and a fourth beam section (44) are arranged along a first center line (L1) passing through a center line (C) of the annular section (3). A second beam section (42) and a third beam section (43) are arranged along a second center line (42) passing through the center line (C). An angle formed by the first center line (L1) and the second center line (L2) is larger than 0° and smaller than 90°, or larger than 90° and smaller than 180°. The determination means (90) determines torque and thrust, on the basis of a relative relation between outputs of the bridge circuits (BrA, BrB). |
