<p><P>PROBLEM TO BE SOLVED: To provide a vehicular power transmission device and its manufacturing method that can suppress an abnormal noise, which arises from the change of a traveling state of a vehicle at the connection portion of a damper provided on the output shaft of an internal combustion engine and the input shaft of a transmission, and deterioration in the durability of the connection portion. <P>SOLUTION: The output shaft 10 of the internal combustion engine is connected to the input shaft 30 of the transmission 90 by the damper 20. This damper 20, which has housings 21, 22 and a rotary member 24 which attenuate torsional vibrations of the output shaft 10 by relative rotation to each other, transmits the torque of the output shaft 10 to the input shaft 30 and attenuates the torsional vibration of the output shaft 10. The rotary member 24 is fitted outside of a hub 23. The output shaft 10 is fixed to the housings 21, 22 via a flywheel 11 in such a way as to be rotatable together. The input shaft 30 is fitted into a fitting hole 23a formed in the hub 23. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
