PURPOSE:To improve the rigidity, by bearing a front power taking-out shaft by a front gear case forward pivot receiver and a front frame below a front gear case, and connecting it through an intermediate shaft to a power taking-out driving shaft below a transmission case. CONSTITUTION:Below the transmission case 1, the power taking-out driving shaft 5 is borne at 3, 4, and the forward part is connected through a transmission shaft 11 to the intermediate shaft 10 borne at 8, 9 in a gear chamber 7 formed below the front frame 6. The forward part of the output shaft 19 borne at 17, 18 in the gear chamber 7 is positioned below the front gear case 13, and is connected through a coupling 23 to the front power taking-out shaft 21 borne on a bearing body 20 attached to the forward pivot receiver 16. The intermediate shaft 10 and the output shaft 19 can transmit power by meshing gears 24, 25. Thus by bearing the front power taking-out shaft 21 by the front pivot receiver and the front frame, the rigidity can be increased, the oscillations of the shaft can be excluded, and the apparatus can endure higher torque. |
