To provide a drum which can inhibit a cable from being wound while partially skipping a groove part.SOLUTION: The drum 40 has a spiral groove 40b formed on an outer peripheral surface 40a and a cable is wound around the spiral groove 40b. The drum 40 includes: a large diameter part 41 which is formed at one axial end side and in which a groove diameter of the spiral groove 40b is large; a small diameter part 43 which is formed at the other axial end side and in which a groove diameter of the spiral groove 40b is small; and a diameter changing part 42 which connects the large diameter part 41 with the small diameter part 43 and in which the groove diameter of the spiral groove 40b gradually reduces from the large diameter part 41 side to the small diameter part 43 side.SELECTED DRAWING: Figure 2

    【課題】 ケーブルが溝部を部分的に飛ばして巻回されることを抑制することが可能なドラムを提供する。【解決手段】 ドラム40は、外周面40aに螺旋溝40bが形成されており、螺旋溝40bにケーブルが巻回されるものであって、軸方向一端部側に形成されており、螺旋溝40bの胴径が大きい大径部41と、軸方向他端部側に形成されており、螺旋溝40bの胴径が小さい小径部43と、大径部41と小径部43とを繋いでおり、螺旋溝40bの胴径が大径部41側から小径部43側に向かって漸減する径変化部42と、を備える。【選択図】 図2
