ABSTRACT:
A governor system is provided for engine starter mechanisms to prevent a premature retracting movement of a single-direction rotatable clutch. The governor system is constructed with a reduced number of parts and such that a clutch does not suffer from the increased angular momentum as it rotates together with a governor weight. The governor system includes a casing or a bracket fixed to a driven gear, with the governor weight received in the casing. The governor weight is provided with a first and a second weight portion which are different in weight from each other such that the center of gravity of the governor weight is disposed radially eccentric. When the rotatable clutch rotates to advance and moves out of a receptacle hole of the governor weight, simultaneously the governor weight rotates to shift in one radially outward direction toward said first or heavier weight portion, the second or lighter weight portion enters into the retracting passage of an advanced inner clutch base portion, thereby preventing the rotatable clutch from retracting prematurely to the initial position.
