PROBLEM TO BE SOLVED: To provide a random winding preventive mechanism for a winch provided with a function that can positively and regularly wind a wire rope even if the fluctuation of tension is generated to the wire rope wound with simple constitution. SOLUTION: In the winch 1 provided with a drum 3 wound in multiple layers, an axially movable guide sheave 20 for the rope R is provided close to the winch drum 3, and a rope pressing roller 6 for applying pressing-energizing force is disposed in the vicinity of a position where the rope R is wound onto the drum. Tensile force is thereby applied constantly to the rope R at a rope winding part to the drum 3. COPYRIGHT: (C)2004,JPO
