<p>Disclosed is a reduction starter employing a planetary gear type reduction gear mechanism having an outer sun gear (6) displaceable in directions perpendicular to a common axis of a central sun gear (4) and an output shaft (10) carrying planet gears (7) for revolution about the common axis. The outer sun gear (6) is formed by an internally toothed ring gear elastically deformable to take up an offset, greater than a predetermined value, of any of the planet gears (7) due to irregular mounting thereof, for thereby avoiding local or uneven contact between gear teeth and assuring a uniform distribution of load torque to all the planet gears (7).</p> |
