ABSTRACT:
A rotary disc of a speed-regulating centrifugal governor driven by a crank shaft is rotatably fitted to a crank case of an engine. While part of the rotary disc is immersed in lubricating oil stored in the crank case, the rotary disc is disposed adjacent to a timing gear and impeller blades project from the outer peripheral face of the rotary disc so as to form an impeller. Further, guide walls for guiding oil splashed by the rotation of the impeller to the timing gear are integrally formed with the inside wall of the crank case, so that the timing gear of a valve mechanism can be effectively lubricated with the splashed oil.
