To provide a traction device with a simple structure capable of lifting heavy goods and to provide a heavy goods transportation vehicle capable of lifting and moving heavy goods.SOLUTION: A traction device 1 has a stretchable bellows 2 and the bellows has a top lid 3 and a lower lid 4. The top lid has an intake port 6 and an exhaust port 7. The intake port 6 and the exhaust port 7 are each connected with a pipe 8 having an intake valve 9 or an exhaust valve 10 at a middle position. The space surrounded by the bellows, the top lid, and the lower lid is airtight when both valves 9, 10 are closed together. A vacuum pump 11 is connected to the other end of the pipe 8 connected to the exhaust port 7. An approximately central part on the lower surface of the lower lid has a hook 5. A heavy goods transportation vehicle has a traction device supporting part, three or more wheels, and a leg part to connect the traction device supporting part and the wheels, where the traction device is fixed to the traction device supporting part.SELECTED DRAWING: Figure 1

    【課題】重量物を吊り上げることができ、構造が簡単な牽引装置および、重量物を吊り上げて移動させることができる重量物運搬用車両を提供する。【解決手段】牽引装置1は伸縮可能なベローズ2を有し、該ベローズは上蓋3と下蓋4を有する。該上蓋は吸気口6と排気7を有する。該吸気口6と該排気口7にはそれぞれ中間に吸気用バルブ9あるいは排気用バルブ10を有する管8が接続されている。該2つのバルブ9及び10を共に閉鎖した時、該ベローズと該上蓋と該下蓋に囲まれた空間は気密性である。該排気口7に接続された管8の他端に真空ポンプ11が接続されている。また該下蓋の下面の略中央部にフック5を有する。重量物運搬用車両は牽引装置支持部と3以上の車輪と、該牽引装置支持部と該車輪を連結する脚部を有し、該牽引装置支持部に前記の牽引装置が固定されている。【選択図】図1
