PURPOSE:To increase hysteresis torque in proportion to an increase in an angle of torsion as well as to absorb torque variations and vibrations in an effective manner, by compressing and pressing silicon oil inside a pipe with an increase in the angle of torsion between a case and a flange. CONSTITUTION:A pipe 18 is fitted in each of springs 15 and 17, and each spring seat 19 capable of slide motion to the pipe 18 is installed in both ends of the pipe 18. And, a through hole 19b and a projection 19d are formed in each of spring seats 19 and 19, covering them with covers 3 and 4, and silicon oil is filled up inside these cases 3 and 4 and the pipe 8. The silicon oil inside the pipe 8 is constituted so as to cause it to be compressed and pressed while blocking up the through hole 19b with a side edge 16a following an increase in an angle of torsion between these cases 3, 4 and a flange 2. With this constitution, hysteresis torque is increasable in proportion to an increase in the angle of torsion and, what is more, torque variations and vibration are effectively adsorbable all the time. |
