Summary:To provide an alignment device of a planetary gear which can suppress the generation of the noise of the planetary gear when the rotation of an inner gear is prohibited.SOLUTION: An alignment device 1 of a planetary gear comprises: a planetary gear 21 including a sun gear 21a, a pinion gear 21b and an internal gear 21c; a backward traveling brake 23 for permitting or prohibiting the rotation of the inner gear 21c; and a plurality of energization mechanisms 24 arranged at an external periphery of the internal gear 21c, and energizing the internal gear 21c to a rotation center direction (inside a radial direction) of the planetary gear 21. The plurality of energization mechanisms 24 energize the internal gear 21c to the rotation center direction of the planetary gear 21 when the rotation of the internal gear 21c is prohibited, and the backward traveling brake 23 prohibits the rotation of the internal gear 21c after the internal gear 21c is energized to the rotation center direction of the planetary gear 21 by the energization mechanisms 24.SELECTED DRAWING: Figure 2 【課題】インターナルギヤの回転を禁止したときのプラネタリギヤの異音の発生を抑えることが可能なプラネタリギヤの調心装置を提供する。【解決手段】プラネタリギヤの調心装置1は、サンギヤ21a、ピニオンギヤ21b、インターナルギヤ21cを含むプラネタリギヤ21と、インターナルギヤ21cの回転を許可又は禁止する後進ブレーキ23と、インターナルギヤ21cの外周に配設され、インターナルギヤ21cをプラネタリギヤ21の回転中心方向(径方向内側)に付勢する複数の付勢機構24とを備え、複数の付勢機構24は、インターナルギヤ21cの回転が禁止される際に、インターナルギヤ21cをプラネタリギヤ21の回転中心方向に付勢し、後進ブレーキ23は、付勢機構24により、インターナルギヤ21cがプラネタリギヤ21の回転中心方向に付勢された後に、インターナルギヤ21cの回転を禁止する。【選択図】 図2
