1st split component the 73 and the 2nd split component 74 is configured to predetermined position.When bent axle 2 is fixed as predetermined angle, the
Any one in 1 split component the 73 and the 2nd split component 74 can be dismantled upward from main part 72.Thus, jackshaft 23
End can pass through breach 75.When the 1st split component the 73 or the 2nd split component 74 is dismantled from main part 72, operation
Person makes jackshaft 23 move to the radial outside of main part 72, in order to dismantled from bent axle 2 by jackshaft 23, and jackshaft 23
End by the breach 75 of main part 72.Thereby, it is possible to jackshaft 23 is taken out from bent axle 2.
On the contrary, by jackshaft 23 in the case of bent axle 2 is installed, make jackshaft 23 move to the central side of main part 72,
So as the breach 75 that the end of jackshaft 23 is by main part 72.Thereby, it is possible to jackshaft 23 is mounted on bent axle 2.
Afterwards, the 1st split component the 73 and the 2nd split component 74 is installed on main part 72.
Make rear end side flywheel 71 rotate, make any one position for axle of the 1st split component the 73 and the 2nd split component 74
In upside such that it is able to jackshaft 23 is taken out from main part 72.I.e., only by making the maximum half-twist of rear end side flywheel 71,
Just jackshaft 23 can be set in the position that can dismantle.
In conventional rear end side flywheel, in order to take out jackshaft, only it is provided with the breach making jackshaft pass through at main part.
Therefore, in order to make the moment of inertia increase, need thicken the thickness of flywheel or increase diameter.On the other hand, according to present embodiment,
1st split component the 73 and the 2nd split component 74 is set at breach 75, therefore, compared with conventional rear end side flywheel, no
Thickness, diameter can be made to increase, it becomes possible to make the moment of inertia of rear end side flywheel 71 increase.Further, by obtaining bigger inertia force,
The twisting vibration of bent axle 2 can be reduced.
Additionally, in the above-described embodiment, to two split components, i.e., the 1st split component the 73 and the 2nd split component
74 can be illustrated relative to the example of main part 72 handling, but the present invention is not limited to this example.Such as, it is possible to
To be, breach 75 is formed along a direction radially only with respect to for the axle of rear end side flywheel 71 in main part, and the only the 1st
Split component 73 can load and unload relative to main part.I.e., the main part of this variation has main part 72 and of above-mentioned embodiment
The shape of the 2nd split component 74 integration.In this variation, only at the 1st split component 73 with position for axle
Mode in upside enables rear end side flywheel 71 to be taken out upward from main part by jackshaft 23 when rotating.
