The invention provides a planetary gear device and a method of manufacturing the same. The planetary gear device is easy to manufacture and enables the amount of pin-shaped parts to be guaranteed. According to the planetary gear device (G1), a first flange body (32) and a second flange body (34) are arranged on two sides along an axial direction of outer gears, i.e. planetary gears (22, 24); a plurality of inner pins (28) serving as the pin-shaped parts and wheel frame pins (30) are arranged between the first flange body (32) and a second flange body (34), wherein the inner pins (28) are formed into a whole body by protruding from the first flange body (32), the wheel frame pins (30) are formed into a whole body by protruding from the second flange body (34); and through staggering of the inner pins (28) of the flange bodies (32, 34) and phases of the wheel frame pins (30) along a circumferential direction, the first flange body (32) and the second flange body (34) are connected. |
