Abstract
A torque detector for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile. A first rotating body is connected to one end of a driving shaft of an engine coaxially, and an annular second rotating body is disposed around a boss which projects from the center of the first rotating body so as to be coaxial and parallel with the first rotating body. An elastic member connects the inner peripheral portion of the second rotating body to the boss in the radial direction. The angular phase difference between the first and the second rotating bodies which occurs due to the deformation of the elastic member is detected, and torque is calculated from the obtained angular phase difference.
