Zusammenfassung:	To realize a planetary gear mechanism which has high overall rigidity and can reduce displacement to a low level even if a large load is applied thereto.SOLUTION: A planetary gear mechanism (2) includes: a pinion gear body (210) having a shaft part (211) and gear parts (212, 213); and a carrier (2D) which rotatably supports the pinion gear body (210). In the pinon gear body (210), the shaft part (211) and the gear parts (212, 213) are integrally formed. The carrier (2D) includes a first member (220) and a second member (230). The first member (220) and the second member (230) are fixed to each other at contact portions (222a, 232a) by welding (242).SELECTED DRAWING: Figure 3 【課題】全体としての剛性が高く、大負荷がかかる場合にも変位量を小さく抑えることができる遊星歯車機構を実現する。【解決手段】遊星歯車機構（２）は、軸部（２１１）とギヤ部（２１２，２１３）とを有するピニオンギヤ体（２１０）と、ピニオンギヤ体（２１０）を回転可能に支持するキャリヤ（２Ｄ）とを備える。ピニオンギヤ体（２１０）は、軸部（２１１）とギヤ部（２１２，２１３）とが一体的に形成されている。キャリヤ（２Ｄ）は、第１部材（２２０）と第２部材（２３０）とを備え、第１部材（２２０）と第２部材（２３０）とがこれらの当接部分（２２２ａ，２３２ａ）において溶接（２４２）により互いに固定されている。【選択図】図３
