Claims

[Scope of utility model registration request]

In the winch, the shaft is rotated forward and backward by a handle, and the wire rope is wound around or unwound to a drum attached to the shaft to be pulled, and the drum is rotatably attached to a fixed drum fixed to the shaft. 1. A winch comprising a rotating drum, and having both ends of a spiral spring connected to the fixed drum and the rotating drum to generate torque between the two drums.
