To provide a multi-joint arm device for heavy object transportation which can easily move a heavy object not only in a vertical direction but also in a horizontal direction and is stable against even a rapid load change.SOLUTION: A multi-joint arm device 1 includes: a first rotary joint 10 which rotates around a vertical axis; a first upper support member 14 in an upper section of the first rotary joint; a first arm 20 which is rotatably connected to the first upper support member around a horizontal axis; a second lower support member 42 to which the first arm is rotatably connected around the horizontal axis; a second rotary joint 40 which rotates around the vertical axis above the second lower support member; a second upper support member 44 above the second rotary joint; a second arm 50 which is rotatably connected to the second upper support member around the horizontal axis; a third lower support member 72 to which the second arm is rotatably connected around the horizontal axis; a third rotary joint 70 which rotates around the vertical axis above the third lower support member; and a driving device 80 which equally changes elevation angles of the first arm and the second arm.SELECTED DRAWING: Figure 1

    【課題】重量物を上下方向のみならず水平方向にも容易に移動可能であり、急激な荷重変化にも安定な重量物運搬用の多関節アーム装置を提供する。【解決手段】鉛直軸回りに回転する第1回転ジョイント10と、第1回転ジョイントの上部の第1上方支持部材14と、第1上方支持部材に水平軸回りに回動可能に接続される第1アーム20と、第1アームが水平軸回りに回動可能に接続される第2下方支持部材42と、第2下方支持部材の上方で鉛直軸回りに回転する第2回転ジョイント40と、第2回転ジョイントの上方の第2上方支持部材44と、第2上方支持部材に水平軸回りに回動可能に接続される第2アーム50と、第2アームが水平軸回りに回動可能に接続される第3下方支持部材72と、第3下方支持部材の上方で鉛直軸回りに回転する第3回転ジョイント70と、第1アームと第2アームの仰角を等しく変化させる駆動装置80とを備える、多関節アーム装置1。【選択図】図1
