To provide a small and space-saving rope traction device.SOLUTION: A differential reduction type speed reducer 5 is attached to a support 2, the speed reducer having an input shaft 7 for detachably connecting an output shaft of a rechargeable electric screwdriver and an output shaft 8 combined with a pulley 20 by which a rope can be detachably wound, and reducing the speed of rotation applied to the input shaft 7 so as to transmit it to the output shaft 8. The support 2 is provided with an inlet 32 and an outlet 33 forming an inlet passage and an outlet passage of the rope wound around the pulley 20. The input shaft 7 of the speed reducer 5 is provided with a ratchet mechanism that allows only forward rotation, prevents reverse rotation, and restricts an inlet side of the rope from being pulled out, and release means that releases the restriction of the ratchet mechanism. The support 2 is provided with an openable/closable pulley cover, rope hooks 80 and 81, and a rope attachment hole for attaching another rope.SELECTED DRAWING: Figure 7

    【課題】 小型で場所を採らないロープ牽引装置を提供する。【解決手段】 充電式電動ドライバの出力軸を着脱自在に連結可能な入力軸7とロープを着脱自在に巻き掛け可能なプーリ20と結合された出力軸8を有し、入力軸7に加えられた回転を減速して出力軸8に伝達する差動減速式の減速装置5を支持体2に装着する。支持体2にはプーリ20に巻き掛けられるロープの入口通路部と出口通路部を成す入口部32及び出口部33を設ける。減速装置5の入力軸7には正転のみ許容し、逆転を阻止してロープの入口側が外側に引き出されるのを制限するラチェット機構及びラチェット機構の制限を解除する解除手段を装備する。支持体2には開閉自在のプーリカバー、ロープの掛け止め部80、81、他のロープを取り付けるロープ取り付け孔を設ける。【選択図】 図7
