The hauling machines of the fishing nets or lines are necessary to have the characteristics of shock absorb and reliable controle of the hauling speed, especially for the large ships of tuna fishing. However, none of old types have these two important characteristics.
The authors intended to reject these defects by the application of torque converter, and carried out the trial production.
By the experiments, we obtained as follows;
1. The charactersistics of the shock absorb and self control of hauling speed, can be obtained.
2. The considerable amount of temperature increasing of the casing occurs by the rotation of the rotors.
