To provide a evacuation rope device, simple in structure, strong, safe, enabling the children to the old to control the speed to be fast and low and suitable to the bodily sensation of each person, causing no change with the passage of time, and reduced in size and weight to be suitable for carrying.

When a rope 12 is wound round a fixed shaft 2 three times, a strong frictional force is generated at this part. About 90% of the hanging load is absorbed by this strong frictional force. The remaining 10% tension acts as turning torque to a drum 4, so that both flange parts of the drum 4 are pressurized by a compression spring 7, whereby while the negative turning torque is generated, the drum 4 is rotated. Subsequently, the compression spring 7 is pressurized and operated by a brake lever 10 so that the person can escape at a descending speed suitable to the bodily sensation of each person.
