A slack correction mechanism (1) is provided with: a distal-end pulley (2) capable of rotating about a predetermined shaft a distal-end wire (3) wound on the distal-end pulley (2) a first supporting part (4) for supporting one side of the distal-end wire (3), the first supporting part (4) having a first base (41), a first friction part (42) protruding from the first base (41), one side of the distal-end wire (3) wound on the distal-end pulley (2) being wrapped in a loop around the first friction part (42), and a first urging part (43) for urging the distal-end wire (3) in a pulling direction at a location further toward one end of the distal-end wire (3) than the first friction part (42) and a second supporting part (5) for supporting the other side of the distal-end wire (3), the second supporting part (5) having a second base (51), a second friction part (52) protruding from the second base (51), the other side of the distal-end wire (3) wound on the distal-end pulley (2) being wrapped in a loop around the second friction part (52), and a second urging part (53) for urging the distal-end wire (3) in the pulling direction at a location further toward the other end of the distal-end wire (3) than the second friction part (52). A manipulator and manipulator system are thereby provided in which a dynamic excess portion is rapidly removed and a distal-end part rapidly actuates in response to operation of an operation part.Linvention concerne un mécanisme de correction de jeu (1) qui est pourvu : dune poulie dextrémité distale (2) pouvant tourner autour dune tige prédéterminée dun fil dextrémité distale (3) enroulé sur la poulie dextrémité distale (2) dune première partie de support (4) pour porter un premier côté du fil dextrémité distale (3), la première partie de support (4) ayant une première base (41), une première partie de frottement (42) faisant saillie sur la première base (41), un premier côté du fil dextrémité distale (3), enroulé sur la poulie dextrémité d
