ルクセンサ。[Claims for Utility Model Registration] Torque is detected by connecting a drive shaft and a driven shaft, which are axially opposed and rotatably supported in a housing, by a torsion bar, and detecting the torsion angle of the torsion bar. In the sensor, the drive shaft includes a magnetic disk provided on the shaft end surface of the drive shaft, and an even number of cores made of magnetic material implanted on a predetermined circumference of the magnetic disk so as to protrude in the axial direction. A primary winding is formed between a member, a coil wound in opposite winding directions in the core member adjacent to each core member, and a primary winding connected to the coil on a stationary housing. and a secondary winding configured to constitute a rotating transformer, the driven shaft includes a magnetic disc provided on the shaft end surface of the driven shaft, and a shaft located on a predetermined circumference of the magnetic disc. An even number of core members made of magnetic material planted so as to protrude in the direction, a coil wound so that the winding directions of the core members adjacent to each core member are opposite to each other, and a connection to the coil. and a secondary winding configured to constitute a second rotating transformer with a primary winding on a stationary housing, wherein each core member of the driven shaft is connected to the drive shaft in a free state. A torque sensor characterized in that each member is arranged so as to be located at the center of the interval between each core member.
