ABSTRACT:
A joint device, wherein a shaft is supported by a base member, and can rotate in a first direction and a second direction. Two coil springs are mounted on the shaft. The first coil spring has an end fixed to the base member. The inner diameter of the first coil spring is smaller than the outer diameter of the shaft. The first coil spring is wound around the shaft in the first direction. The first coil spring is wound tightly around the shaft when the shaft is rotated in the first direction. An arm is attached to the shaft. The arm twists the free end of the first coil spring in the second direction, whereby a return torque is accumulated in the first coil spring. The second coil spring also has an end fixed to the base member. The free end of the second coil spring is twisted when the shaft is rotated in the second direction, whereby a return torque is accumulated in the second coil spring.
