To provide an outrigger device of a work vehicle capable of smoothly operating a cylinder.SOLUTION: Each outrigger 6 is constituted of a first arm 8, a second arm 9, and a third arm 10 in a telescopic type capable of expanding/contracting in a length direction. A tip of a piston rod 17A of an upper side cylinder 17 is fixed to the first arm 8 and a cylinder tube 17B of the upper side cylinder 17 is fixed to the second arm 9. A tip of a piston rod 18A of a lower side cylinder 18 is fixed to a third arm 10 and a cylinder tube 18B of the lower side cylinder 18 is fixed to the second arm 9. A support section 24 for supporting the cylinder tube 18B at a position deviated from a fixed position to the second arm 9 in a cylinder shaft direction is fixed to any one of the arms. A transmission member for transmitting a load of the upper side cylinder 17 to the lower side cylinder 18 is provided at a position deviated from a fixed position to the second arm 9 in the cylinder shaft direction in the cylinder tube 17B.SELECTED DRAWING: Figure 3B

    【課題】シリンダをスムーズに動作させることができる作業車のアウトリガ装置を提供する。【解決手段】各アウトリガ6は、第1アーム8、第2アーム9、第3アーム10を長さ方向に伸縮可能な入れ子式に構成され、上側のシリンダ17のピストンロッド17Aの先端部を第1アーム8に固定し、上側のシリンダ17のシリンダチューブ17Bを第2アーム9に固定し、下側のシリンダ18のピストンロッド18Aの先端部を第3アーム10に固定し、下側のシリンダ18のシリンダチューブ18Bを第2アーム9に固定し、シリンダチューブ18Bを第2アーム9への固定位置に対してシリンダ軸方向でずれた位置で支持する支持部24をどれかのアームに固定し、上側のシリンダ17の荷重を下側のシリンダ18に伝達するための伝達部材を、シリンダチューブ17Bにおける第2アーム9への固定位置に対してシリンダ軸方向でずれた位置に設けた。【選択図】図3B
