これにより、低速段サンギアを組み付けた際に、低速段サンギアが自動的に調芯され(低速段サンギアの中心と低速段遊星ギアの中心との距離がそれぞれ等しくなる位置に、低速段サンギアが自動的に移動し)、低速段サンギアおよび低速段遊星ギアの歯面、および入力軸を回転可能に支持する軸受の損傷を防止することができる。
これにより、低速段サンギアを組み付けた際に、低速段サンギアが自動的に調芯され(低速段サンギアの中心と低速段遊星ギアの中心との距離がそれぞれ等しくなる位置に、低速段サンギアが自動的に移動し)、低速段サンギアおよび低速段遊星ギアの歯面、および入力軸を回転可能に支持する軸受の損傷を防止することができる。
