ABSTRACT:
A governor shaft for supporting a governor valve is rotatably supported to a transmission case by a stopper pin. The governor shaft is formed with an annular groove having a rectangular cross section. The stopper pin is inserted through the transmission case, and engaged with the annular groove of the governor shaft for preventing the governor shaft from being extracted and allowing the rotation of the governor shaft. The stopper pin has two cylindrical portions and a middle portion lying between the cylindrical portions. The middle portion is received in the annular groove, and the cylindrical portions are supported by the transmission case. In one embodiment of the present invention, the middle portion has a square cross section, so that the stopper pin tends to be in face contact with the annular groove. The cylindrical portions are arranged to allow the stopper pin to rotate to a limited extent.
