Torque sensor
 A torque sensor for detecting variation in the drive torque of an automobile comprises an excitation coil wound on an excitation core and a detection coil wound on a detection core. The coils and cores are inserted into a chamber formed within a bearing for supporting a drive shaft and having an opening along the sliding surface of the bearing. The poles of the excitation core and the poles of the detection core are respectively disposed at prescribed clearances from the surface of the drive shaft in such manner that the poles of the detection core intersect the excitation core between its poles, whereby variation in drive torque is detected as magnetostriction.
