To provide a rope irregular winding prevention device for a winch capable of ensuring prevention of rope irregular winding.SOLUTION: This rope irregular winding prevention device for a winch is provided with; a movable sheave 51 which is provided so as to be movable in the rotational axis direction of a winch drum 24a and on which a rope 22 wound on the winch drum 24a is hung; and a resistance application mechanism 52 for applying resistance to the rotational axis force of the winch drum 24a applied to the movable sheave 51. Thus, the movable sheave 51 is enabled to follow the moving speed of the rope 22 during normal taking-up of the rope 22, and the movement of the rope 22 at a speed causing jumping of the rope 22 wound on the winch drum 24a can be suppressed. Thus, prevention of irregular winding of the rope 22 can be ensured.SELECTED DRAWING: Figure 3

    【課題】ロープの乱巻を確実に防止することのできるウインチのロープ乱巻防止装置を提供する。【解決手段】ウインチドラム24aの回転軸方向に移動自在に設けられ、ウインチドラム24aに巻き掛けられるロープ22が掛けられる可動シーブ51と、可動シーブ51に対して作用するウインチドラム24aの回転軸方向の力に対して抵抗力を付与する油圧式の抵抗力付与機構52と、を備えている。これにより、正常なロープ22の巻き取り動作時におけるロープ22の移動速さに可動シーブ51を追従させるとともに、ウインチドラム24aに巻き掛けられるロープ22の飛びが発生する速さのロープ22の移動を抑制することができるので、ロープ22の乱巻の発生を確実に防止することが可能となる。【選択図】図3
