Abstract
Phase differences generated between respective pairs of rotating members and stationary members mounted on the drive side and load side of a torque transmission shaft are converted into relative opening amounts produced by slits formed in the above pairs of rotating members and stationary members, respectively, and the opening amounts are detected by two opening amount transducers and converted into electric signals. The torque transmitted to the torque transmission shaft is measured by detecting relative phase differences between both rotating members from periodic changes in the outputs from these two opening amount transducers.
