Therefore, as illustrated in FIG. 1, the transmission case is divided and configured into a front transmission case (1) and a rear transmission case (2), respectively, for example, a 1st stage transmission mechanism (3) and a 1IIE 3 stage transmission mechanism. The spacer case (6) containing the mechanism (4) and the second stage transmission mechanism (5) is installed between the front and rear transmission cases to enable multi-stage transmission. There are known tractors that do not use this two-spacer case (6). A hydraulic cylinder (7) and a piston (8) for lifting the work equipment are provided in the upper part of the rear transmission case (2), and a lift arm (9) and a piston (8) are connected to each other. A hole (2a) for internally installing the hydraulic cylinder (7), etc. is provided in the upper part of this rear transmission case (2), but in order to keep the total length of these transmission cases as short as possible, a spacer transmission case ( 6) Due to the length of the case (2), it was necessary to hide the smoke.
In addition, in order to secure the length of the holes necessary for the interior of the hydraulic cylinder (7), etc., it is necessary to spread the holes from the front end (2b) of the rear transmission case (2) to the front rut of this hole (211). The dimensions of the part (the force becomes shorter, 5 and k, and as a result,
Spacer mission case (6) t Front mission case (1)
) is installed, there is a problem that the strength of this defeated part is insufficient and vibration becomes large during use.
