METHOD FOR FORMING MAGNETOELASTIC MEMBER USED FOR TORQUE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a torque sensor which generates a low hysteresis after yield torque is provided and a method for manufacturing the torque sensor with a low hysteresis. SOLUTION: The external diameter of a cylindrical base 108 which is thin and long is increased, a magnetoelastic material 104 is provided on the base, and then the external diameter of the base is reduced.
