Abstract
A device for generating limit torque with a function of yielding a torque change in real time includes a spring, a rotating portion having a cam surface formed therein, a transmitting portion transmitting an elastic force of the spring to the cam surface, a fixed portion with respect to which the relative rotation of the rotating portion is generated, and a limit-torque control portion provided to the fixed portion so as to control limit torque of the rotating portion by adjusting the elastic force of the spring. In the device, the limit-torque control portion controls the limit torque of the spring by changing the elastic force of the spring in real time.
