ABSTRACT:
In an automatic transmission having a torque converter with a pump impeller, a turbine runner, and a stator, a stator shaft is provided to support the stator on its outer periphery and to rotatably support a transmission input shaft on its inner periphery. A magnetostrictive torque sensor is provided to detect the magnitude of input torque transmitted to the transmission input shaft. The magnetostrictive torque sensor includes a magnetic material having a magnetostrictive property and attached onto the outer periphery of the transmission input shaft, and a cylindrical magnetic-property detector mounted on the inner periphery of the stator shaft and arranged to be opposite to the magnetic material to detect a change in a magnetic property of the magnetic material, occurring owing to the input torque applied to the transmission input shaft.
