To provide a magical planetary gear mechanism in which a common planetary gear to be arranged around a sun gear can be applied by assembling planetary gears respectively engaged with internal gears having the different number of teeth with a prescribed phase difference with high accuracy in an integrally rotatable manner.SOLUTION: A magical planetary gear mechanism is provided with a plurality of collars 6 assembled to a first planetary gear 2 and a second planetary gear 4 on the same axis to be integrally rotatable, forms a first collar side engagement part 62 and a second collar side engagement part 63 engageable with gear side engagement parts 22, 42 provided on inner peripheral surfaces of the first planetary gear 2 and the second planetary gear 4, respectively to extend in an axial direction in each collar 6, and shifts the positions of the first collar side engagement part 62 and the second collar side engagement part 63 in a circumferential direction of the collar 6 in accordance with a phase difference between the first planetary gear 2 and the second planetary gear 4 on the same axis calculated on the basis of at least a difference in the numbers of teeth between the movable internal gear 3 and a fixed internal gear 5.SELECTED DRAWING: Figure 3

    【課題】歯数の異なる内歯車にそれぞれ噛み合う遊星歯車同士を所定の位相差で高精度に一体回転可能に組み付け、太陽歯車の周囲に配置する遊星歯車は共通のものを適用可能な不思議遊星歯車機構を提供する。【解決手段】同軸上の第1遊星歯車2及び第2遊星歯車4に組み付けられて一体回転可能な複数のカラー6を備え、各カラー6に、第1遊星歯車2及び第2遊星歯車4の内周面にそれぞれ設けた軸方向に延伸する歯車側係合部22,42に係合可能な第1カラー側係合部62と第2カラー側係合部63とを形成し、少なくとも可動内歯車3と固定内歯車5の歯数差に基づいて算出される同軸上の第1遊星歯車2と第2遊星歯車4の位相差に応じて、第1カラー側係合部62と第2カラー側係合部63の位置をカラー6の周方向にずらした構成にした。【選択図】図3
