PROBLEM TO BE SOLVED: To restrict transmission of pulsation at the time of idling for preventing generation of abnormal sound from a transmission case in connecting an output shaft of an engine to an input shaft of a transmission device through a drive transmission shaft. SOLUTION: A flywheel 21 is fixed to an output shaft 20 of an engine, and a flange plate 22 is installed on a back surface of the flywheel 21. The flange plate 22 is disposed between a boss 23 and an outline part 24 around it along a circle as a combination of large and small springs 25a, 25b. A drive transmission shaft 14 is engaged with the boss 23 on the flange plate 22, and a forward end part of the drive transmission shaft 14 is pivotally supported by a shaft bearing part 29 of the flywheel 21 to be rotatable. |
