The configuration is simple, and the mission case 8 can be made compact and lightweight. Moreover, with respect to the constant rotation of the ring gear 10 of the planetary gear mechanism 2, the rotation of the sun gear 3 that is continuously variable transmitted from the belt 13 changes the rotation of the carrier 14 from the neutral N to the high speed on the forward rotation F side, and It is possible to continuously perform continuously variable speeds such as reverse rotation R side high speed, and it is possible to easily perform reverse movement reverse movement and continuously variable speed change by a single speed change lever 32. Further, the continuously variable transmission belt transmission system B is a bell.
It is accommodated in the case 16 in a substantially sealed state. That
Outside the gear case 19 that constitutes the mission case 8.
The side wall, the space inside the gear case 19 and the belt case 16

Rod 30 that controls the shifting operation of continuously variable transmission belt B
Are connected. The other end of the bell crank shaft 31
A shift lever 32 is connected to the side. Therefore, the above
The speed-changing belt transmission system B includes a partition wall 36 and a belt case 1.
6 and the gear shift operation in a substantially sealed state.
Can be made. Thereby, the belt case 16
Prevents ingress of dust, mud, water, etc., into the continuously variable bell
The atmosphere of power transmission system B is not affected by the external environment.
Can be kept in a state. Continuously variable transmission, which was mentioned in the section on issues
Prevents damage to the belt and pulleys that make up the belt drive system B
Of course, it can be turned off. Also, a normal combine
The belt case 16 has a
If the casing 8 is provided on the outer surface side of the fuselage, the bell
The other end of the crankshaft 31 should be located inside the machine.
Become. At this time, the shift lever 32 provided in the control section is
Since it is normally placed inside the fuselage, the bell crankshaft
It is very easy and simple to use the structure of connecting with the other end of 31.
be able to. The bell crank shaft 31 has a gear case.
-A partition for partitioning the space inside the case 19 and the space inside the belt case 16
It is "rotationally operated" with a through shaft supported by the cut wall 36.
Therefore, the moisture normally filled in the mission case 8 is
