PROBLEM TO BE SOLVED: To enable a removal of a stopper pin 72 out of a pin hole 73 for restricting an axial direction motion of planetary carriers Cand Cto a supporting hole 71 at a gear supporting shaft 33 for planetary gears P, Pto be carried out without applying any additional steps such as press-fitting, screwing and fastening or the like.SOLUTION: A restriction of motions of planetary gears P, Pof a planetary gear device in axial direction of a gear supporting shaft 33 is performed by inserting a removal stopper pin 72 into a pin hole 73 passing from outer diameter sides of planetary carriers C, Cin a radial direction at a gear supporting shaft 33, the pin hole 73 opened at outer diameter surfaces of the planetary carriers C, Cis closed by an inner ring 39a of a roller bearing 39 supporting the inner gears R, Rin respect to the planetary carriers C, Cand removal of the removal stopper pin 72 from the pin hole 73 is prevented.SELECTED DRAWING: Figure 3

    【課題】 遊星ギヤPL、PRの歯車支持軸33における遊星キャリヤCL、CRの支持孔71に対する軸方向移動の規制を行う抜け止めピン72のピン穴73からの抜け出しを、圧入、ねじ込み、加締め等といった追加工程なく行えるようにする。【解決手段】 遊星歯車装置における遊星ギヤPL、PRの歯車支持軸33の軸方向移動の規制を、遊星キャリヤCL、CRの外径側から歯車支持軸33を径方向に貫通するピン穴73に抜け止めピン72を挿し込むことによって行い、遊星キャリヤCL、CRの外径面に開口するピン穴73を、内歯車RL、RRを遊星キャリヤCL、CRに対して支持する転がり軸受39の内輪39aによって塞ぎ、ピン穴73からの抜け止めピン72の抜け出しを防止した。【選択図】 図3
