To provide a pipe cleaning device, which can effectively remove a foreign substance (for instance rust and dust) generated in an inner wall of a pipe in a comparatively smaller number of cleaning operation in comparison with a cleaning pig for cleaning inside of the pipe.SOLUTION: The pipe cleaning device comprises, in at least either one of a pair of pigs P1 and P2 provided side by side in a pipe-axis direction along a pipe axis of a steel pipe Py, a movement force transmitting part 30 that transmits force moving in an advancing direction along the pipe axis, polishing materials K1 that are sealed into a cleaning space SK externally surrounded by the pair of pigs P1 and P2 and the inner wall of the steel pipe Py to polish a foreign substance adhering to the inner wall of the steel pipe Py, and a stirring force applying mechanism that is sealed into the cleaning space SK to apply stirring force to the polishing materials K1 or stirring materials K2 which transmit stirring force to the polishing materials K1.SELECTED DRAWING: Figure 1 【課題】管の内部を清掃する清掃用のピグに比べ、比較的少ない清掃回数で、管の内壁に発生する異物（例えば、錆や塵埃）を効果的に除去して取り除く。【解決手段】鋼管Ｐｙの管軸に沿う管軸方向に並んで設けられる一対のピグＰ１、Ｐ２の少なくとも一方に、管軸に沿う進行方向へ移動する力を伝達する移動力伝達部３０と、一対のピグＰ１、Ｐ２と鋼管Ｐｙの内壁にて外囲される清掃空間ＳＫに封入され、鋼管Ｐｙの内壁に付着する異物を研磨する研磨材Ｋ１と、清掃空間ＳＫへ封入され、研磨材Ｋ１又は研磨材Ｋ１に撹拌力を伝達する撹拌材Ｋ２に対して撹拌力を付与する撹拌力付与機構とを有する。【選択図】図１
