<p><P>PROBLEM TO BE SOLVED: To easily use a transmission case of approximately same structure in common from a traveling work machine of low horsepower output to a traveling work machine of high horsepower output largely different from each other in horsepower band, to reduce the manufacturing cost of the transmission case, and to simplify parts management. <P>SOLUTION: In a tractor comprising an engine, provided with the transmission case supported by wheels, and having a differential gear mechanism and a counter shaft for transmitting gear shift output to the differential gear mechanism inside of the transmission case in a state that a ring gear of the differential gear mechanism is engaged with a pinion of the counter shaft, the counter shaft is supported on the transmission case by a bearing at a piston side and a bearing at the other end side, and a bearing pressing plate for controlling the axial movement of the counter shaft is mounted at a bearing side of the other end side. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
