PROBLEM TO BE SOLVED: To accomplish highly elastic torque transmission by means of simple manufacturing by correcting axis directional transition of a shaft by means of insertion joint which is previously assembled and fixed in a driving device without requiring any adjusting apparatus. SOLUTION: A fixing flange 1, which is made of steel, for example, in a joint is connected to a plastic joint flange 3 by means of a ring type rotational elastic member 2 made of elastic material, and a steel joint sleeve 4 is fitted in the joint flange 3. The joint sleeve 4, which is provided with an external tooth 5 and an internal tooth 6, is positioned inside the joint flange 3 precisely by means of a ring type flange touching a ring type offset face 8 of the sleeve 4 and an offset 7, and by means of a ring 9, axis directional transition of the sleeve 4 is prevented. In assembly, the joint, which is completely assembled as a unit previously, is fixed in a flywheel in a driving device by means of a screw. In the case of connection with a driven device, a driven shaft provided with a corresponding external tooth is inserted into the central opening part provided with an internal tooth in the joint sleeve 4. |
