PROBLEM TO BE SOLVED: To provide a removal device for lead-in line which removes a lead-in line safely.SOLUTION: A removal device 10 includes a grasping tool 1 having a parallel crank mechanism 1m and an anchoring tool 2. The parallel crank mechanism 1m can grasp a lead-in line We by means of a pair of link members 1a, 1b. The anchoring tool 2 has a hook 2h that can be anchored freely to the supporting point of a house, and an operation lever 2r that can be coupled freely with the grasping tool 1. The grasping tool 1 has an extension rod 11 extending from the link member 1a, and can be arranged freely along the lead-in line We on the underside thereof, a coupling ring 11r formed at the tip of the extension rod 11, and an operation handle member 12 having a U-shaped ring 12d, that can be introduced freely from the upper side of the lead-in line We, at the tip thereof. In a state where the U-shaped ring 12d is locked to the lead-in line We, the link members 1a, 1b are brought close to each other to grasp the lead-in line We, and when the lead-in line We is cut between the U-shaped ring 12d and supporting point, the grasping tool 1 and anchoring tool 2 can be stretched substantially on a straight line by the tension of the lead-in line We.SELECTED DRAWING: Figure 1 【課題】引込線を安全に撤去する引込線用撤去装置を提供する。【解決手段】撤去装置１０は、平行クランク機構１ｍを有する掴持具１と引留具２を備える。平行クランク機構１ｍは、一組のリンク部材１ａ・１ｂで引込線Ｗｅを掴持できる。引留具２は、家屋の支持点に引き留め自在なフック２ｈと、掴持具１と連結自在な操作レバー２ｒを有する。掴持具１は、リンク部材１ａから延出し、引込線Ｗｅに沿って引込線Ｗｅの下側に配置自在な延出棒１１と、延出棒１１の先端部に形成した連結環１１ｒと、引込線Ｗｅの上側から導入自在なＵ字環１２ｄを先端部に有する操作ハンドル部材１２と、を有する。Ｕ字環１２ｄを引込線Ｗｅに係止した状態では、リンク部材１ａ・１ｂを互いに近接させて、引込線Ｗｅを掴持し、Ｕ字環１２ｄと支持点の間で引込線Ｗｅを切断すると、引込線Ｗｅの張力で掴持具１と引留具２を略一直線上に張設できる。【選択図】図１
