Abstract

PURPOSE: To provide governor which makes possible a stable and accurate detection of excessive speed with a relative rotation checking device empleying a closed friction resistance inserted between a pendulum carrier and a governor pulley in parallel with a vibration cutting spring.
CONSTITUTION: Both ends of a vibration cutting spring 27 are engaged with a pin 25 fixed to a governor pulley 23 wounded with a governor rope 22 and a pin 26 fixed to a pendulum carrier 24. The governor pulley 23 and the pendulum carrier elastically combined in the rotating dricetion is supported rotatively around a shaft 28 while a pendulum 30 is supported rotatively around a shaft 29 fixed to the pendulum carrier 24. A disc-shaped brake plate 31 fixed to the pulley 23 and a disc- shaped closing means 37 provided on the pendulum carrier 37 are arranged as opposed to each other. A brake piece 32 is arranged in a closed space demarcated by a circular projection 38 provided on the brake plate 31 a cover 40 and the closing means 37
