PROBLEM TO BE SOLVED: To provide a winch configured to have a highly reliable, robust and relatively simple structure, and to allow a tension strand to orderly perform winding and unwinding operations.SOLUTION: A winch (10) comprises: a winding drum (22) capable of rotating about a center axis (A) so that a tension strand (12) can be wound/unwound through winding extending around the winding drum (22); and a rotary actuator (20) for driving rotation of the winding drum (22), where the winding drum (22) is movably arranged in a longitudinal direction along a center axis (A) with respect to a basic body (52) of the winch (10). The winch is further provided with a threaded rod (28) with a male thread (30) extending to the center axis (A), and the winding drum (22) is rotatably arranged about the threaded rod (28) with a corresponding thread (36) engaged with the male thread (30).SELECTED DRAWING: Figure 2

    【課題】引張ストランドの整然とした巻取と巻出を可能にする、信頼度が高く頑丈で比較的簡素に構成されたウインチを提供する。【解決手段】巻付ドラム(22)の周りに延びる巻回で引張ストランド(12)を巻取可能かつ巻出可能であるように中心軸(A)を中心として回転可能である巻付ドラム(22)と、巻付ドラム(22)の回転を駆動するための回転アクチュエータ(20)とを有し、巻付ドラム(22)がウインチ(10)の基体(52)に関して中心軸(A)に沿って長手方向に可動に配置されているウインチ(10)において、中心軸(A)に延びる、雄ねじ(30)を備えたねじ付ロッド(28)が設けられており、巻付ドラム(22)は雄ねじ(30)に係合する対応ねじ(36)によってねじ付ロッド(28)の周りで回転可能に配置されている。【選択図】図2
