The present invention provides a working vehicle, which can perform the disassembly operation of a working device easily, and does not require excessive staffs. In the working vehicle, a cab sets up a lifting link mechanism, the lifting link mechanism sets up a support suspension for the work device to cary out the assembly, the work device sets up an assembly suspension to connect with the support suspension, and the assembly suspension sets up a rotary shaft to make the work device rotating left and right. In the above-mentioned working vehicle, the support suspension sets up a rotary cylinder (71), an end (74) of a slide bar (71b) of the rotary cylinder (71) forms a first thread hole (74a) of the body in the front-rear direction. The assembly suspension sets up an installation member (72). The installation member (72) forms a second thread hole (72c) of the body in the front-rear direction. A screw member (76) with a grip is set to screw in with the first thread hole (74a) and the second thread hole (72c).本發明提供作業車輛,能夠容易地進行作業裝置的拆裝作業,並且不需要過多的作業人數。該作業車輛,在行駛車體設置升降連桿機構,在升降連桿機構設置對作業裝置進行裝配的支承懸掛,在作業裝置設置與支承懸掛連接的裝配懸掛,並且在裝配懸掛設置使作業裝置左右轉動的轉動軸,在上述作業車輛中,在支承懸掛設置轉動筒(71),在轉動筒(71)的滑動桿(71b)的桿端(74)形成機體前後方向的第一螺紋孔(74a),在裝配懸掛設置安裝部件(72),在安裝部件(72)形成機體前後方向的第二螺紋孔(72c),帶握柄的螺栓部件(76)螺合於第一螺紋孔(74a)和第二螺紋孔(72c)而設置。67‧‧‧連結軸7‧‧‧轉動機構71‧‧‧轉動筒71a‧‧‧筒殼體71b‧‧‧滑動桿72‧‧‧安裝部件72c‧‧‧第二螺紋孔74‧‧‧桿端74a‧‧‧第一螺紋孔76‧‧‧螺栓部件76a‧‧‧第二螺紋部76b‧‧‧握柄部
