Abstract
A torque sensor includes a driving rod, a driving body connected fixedly to the driving rod, and a driving block extending from the driving body and having two opposite pushing surfaces, a driven body permitting the driving body to rotate relative thereto as a result of application of a torque to the driving rod, a driven rod extending from the driven body, and a block-receiving groove formed in the driven body. A first measuring module is connected to the driving block. A second measuring module is connected to the driven body, and cooperates with the first measuring module so as to measure the torque. Two resilient members flank the driving block. Each of the resilient members is disposed between and abuts against the corresponding pushing surface and the driven body.
