To provide a governor force transmitting device not ony capable of making a governor force input part make a rotation within a proper rotational moving area and infallibly transmit governor force but also reducing the number of part items and assembling manhours and make it unexpensively.

The support shaft 6 for a governor lever 4 is provided on the fixed wall 5 of an engine in a freely rotationally movable manner and a governor force input part 9 is provided on the support shaft 6 in integrally rotationally movable manner. The output part 13 of a centrifugal type governor 10 is abutted upon the governor force input part 9 which is rotationally moved around a shaft center 18 of the support shaft 6 by transmission of governor force F. A rib 20 is protrusively provided on the fixed wall 5 of the engine in the condition of a rotationally moving area 19 of the governor force input part 9 crossing the rib 20. A notch groove 21 is provided on the rib 21 covering the rotationally moving area 19 and a guide surface 22 for the governor force input part 9 is composed on both sides of the notch groove 21.
