<p>PROBLEM TO BE SOLVED: To prevent a pressure detecting element of a torque sensor from being broken due to application of shearing force, and also prevent the detecting accuracy of transmission torque from lowering due to hysteresis. SOLUTION: A torque sensor is constituted such that pressure detecting element 60 is provided on either one of a first or second rotating members 20, 30 being set rotatably to each other, and transmission torque is detected by pressing the pressure detecting element with pressure in accordance with the torque transmitted between both the rotating members by a pressing part 25 provided at the other side, in which pressing force applied on the pressure detecting element is allowed not to be inclined with respect to its pressure receiving central axis. For this, pressure from the pressing part is transmitted to the pressure detecting element via transmitting means 40 guide-supported slidably in the direction of the pressure receiving central axis of the pressure detecting element, and a rotating body being rotatable around the axis in parallel with the rotating axis of the rotating member, or the pressure detecting element is supported on the rotating member at which it is provided to be in parallel with the rotating axis and tiltable around the axis passing through the pressure receiving central axis.</p> |
