PROBLEM TO BE SOLVED: To provide a travelling vehicle with an operation unit for enhancing working efficiency by improving operability of a working machine connected to a working vehicle.SOLUTION: A lifting lever 130 of a working machine 84 operable in two stages for each of one direction and the other direction is provide near by a steering handle 73 of the working vehicle and is provided, and further, a control processing device 100 operating the working machine 84 when the lever 130 is operated is provided. The device 100 can perform lifting and on/off operations of driving power of the working machine 84 by means of one lifting lever 130 and does not increase an operation space by operating the lever 130 to a first stage in one direction or the other direction to turn on/off working of the working machine 84, and by operating the lever 130 to a second stage to perform processing to move the working machine 84 upward or downward without increasing the working space. The operability of the working machine 84 becomes excellent and working efficiency is improved. As a substitute for the lever 130, a lift switch 191 may be provided near by a drivers seat 16.COPYRIGHT: (C)2009,JPO&INPIT【課題】作業車両に連結された作業機の操作性を良くして作業効率を高めるための操作部を備えた走行車両を提供することである。【解決手段】作業車両のステアリングハンドル73の近傍に一方向及び他方向にそれぞれ2段階に操作可能な作業機84の昇降用レバー130を設け、更に該昇降用レバー130を操作すると作業機84を作動させる制御処理装置100を設ける。制御処理装置100は、昇降用レバー130を一方向又は他方向に第1段階目に操作するとそれぞれ作業機84の作動の入り又は切りをし、第2段階目に操作するとそれぞれ作業機84を上昇又は下降させる処理を行うことで、一本の昇降用レバー130により作業機84の昇降及び動力の入り切りもでき、操作スペースを増やすことがない。また、作業機84の操作性が良好になり、作業効率が上がる。また、昇降用レバー130ではなく、昇降用スイッチ191として操縦席16の近傍に設けても良い。【選択図】図2
