<P>PROBLEM TO BE SOLVED: To provide a transmission for a tractor capable of simplifying the configuration of a case to store a power division unit to divide the power of a prime mover into a working system and a running system with a hydrostatic continuously variable transmission provided therein, a transmission unit to transmit the power to a gear change unit of a transmission or the like. <P>SOLUTION: The transmission 1 for tractor comprises a power division unit by a hydrostatic continuously variable transmission 6, transmission units 7 and 10 to transmit each power, a gear change unit 12 by a sub speed change mechanism to change the rotational ratio of the power of the running system, and a substantially cylindrical case 3. A supporting wall 18 integrated with the case 3, and front and rear support metals 18a and 19a separately fitted to the case 3 are stored in the case 3, and the transmission units 7 and 10 are supported by the supporting wall 18 and the front and rear support metals 18a and 19a. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
