PURPOSE: To stably transmit torque for a long time so as to unify tolerances of connection parts and so as to prevent deformation of a friction lining supporting plate by connecting the supporting plate and hub plates alternately by means of a spring collet transmitting torque without any backlash. CONSTITUTION: An elastic spring collet 30 provided with a slit and used for transmitting torque is inserted into aligned bores 20, 28 of both hub plates 12, 14 and a supporting plate 16 so as to be provided with initial tension. An iron sleeve 36 is made of soft steel material contrarily to the material for the collet 30, and flanges can be formed in both ends of the sleeve 36 without any complicated deforming work after insertion is finished. Therefore, the iron sleeve 36 holding a friction element is supported to an outside front face 34 of the hub plates 12, 14 so that the collet 30 is not slid outward. In this way, the hub plates 12, 14 are connected to the supporting plate 16 while prevented from turning or oscillating. |
