PURPOSE:To enhance working efficiency by facilitating the mounting and detachment of a torque sensor with respect to a shaft to be measured, by structurally separating the torque sensor from the shaft to be measured to constitute the same as a single body and directly mounting said single body to the shaft to be mounted to make it possible to detect torque. CONSTITUTION:A cylindrical member 12 having a cylindrical surface is provided to a shaft to be measured through a fixing means and a detachment means and an amorphous magnetic membrane 20 is fixed to the cylindrical surface. Further, a housing 56 having a cylindrical inner surface is mounted to the outer periphery of the cylindrical member 12 on a common axis in a freely rotatable manner. An exciting coil 80 and a detection coil 84 are mounted to the inner surface of a housing lid part 62 and arranged in opposed relation to a magnetic body fixing surface so as to be capable of being mounted on the shaft to be measured in a freely detachable manner through the cylindrical member 12. Further, a fixing means is constituted of first and second wedge-shaped taper rings 36, 38. By this constitution, the mounting and detachment of a torque sensor with respect to the shaft to be measured is made easy and the enhancement of working efficiency can be achieved.
