ABSTRACT:
A torque sensor in which a main shaft and a follower shaft are supported rotatably relative to each other on a common axis. A sleeve is supported axially slidable on one of the main and follower shafts. A deviation sensor is responsive to axial movement of the sleeve to output a signal corresponding to the quantity of the axial movement. At least one set of torque transmitting members is provided to transmit the torque applied to the main shaft to the follower shaft and to move the sleeve axially in accordance with the torque. The at least one set of torque transmitting members comprises a first connection body extending parallel to the common axis, inclined in a plane offset radially of the main and follower shafts, and connected at one and the other ends to the sleeve and main shaft, respectively. It also includes a second connection body provided inclined in the plane and in the opposite direction to that in which the first connection body is inclined, and connected at one and the other ends to the sleeve and the follower shaft, respectively.
