PROBLEM TO BE SOLVED: To adjust a backlash of planetary gears, by putting a planetary shaft of a first planetary gear through a second carrier piece with play given thereto and putting a planetary shaft of a second planetary gear through a first carrier piece with play given thereto. SOLUTION: A first and a second carrier piece 38, 39 of two-split type are rotatably supported by a device casing 2 of a planetary gear device 1. A first through hole 51 bored in the first carrier piece has an inner diameter allowing a planetary shaft 71 to pass therethrough with play given thereto and a second through hole 52 has a size allowing a planetary shaft 72 to be fitted thereinto. On the contrary, as for the second carrier piece 39, a second through hole 62 has an inner diameter allowing the planetary shaft 72 to pass therethrough with play given thereto and a first through hole 61 has a size allowing the planetary shaft 71 to be fitted thereinto. This enables the two carrier pieces 38, 39 to be grasped and rotated relatively, thus a backlash can be adjusted. |
