STEERING UNIT FOR PADDTY FIELD WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To compact the size of a torque generator. SOLUTION: A torque generator 43 for the hydraulic power steering is linked to the upper face of the transmission case 9 arranged above the front steering wheel 1, the vertical rotary shaft that is synchronously connected to this torque generator 43 is synchronously linked to the pitman arm shaft 92a. In addition, an intermediate joint 99 that is equipped with the interlocking part that is relatively swingable and torque-transmittably fitted to the swing motion- outputting shaft 43b of the torque generator 43 and with the output unit to the vertical rotary shaft 95 is supported by the transmission case 9 rotatably around the vertical shaft axis P.
