PURPOSE:To prevent the wear of a governor valve shaft against a stopper pin even while the shaft is revolving, by fitting a stopper pin piercing through from the outside of a housing into a groove having U-shaped section formed toward the circumference of the shaft. CONSTITUTION:A stopper pin 16 pierces through into a circular groove 9a formed toward the circumference of a governor valve shaft from the outside of a mission housing 1. The pin 16 is formed into a square form having a plane part 16a which touches the governor valve shaft. The bearing parts across the shaft are formed into columnar parts 16d and 16c; while the groove 9a formed to the shaft has a U-shaped section to have a contact with the part 16a of the pin 16. The parts 16b and 16c can have a certain amount of revolutions to the pin 16 in order to have an effective planar contact. |
