PROBLEM TO BE SOLVED: To precisely assemble a planetary carrier by engaging first and second pinions with each other while suppressing tooth tips from being damaged.SOLUTION: A pinion gear assembly mechanism 40 of a planetary gear assembly device 1 is configured to engage first and second pinion gears 110, 120 with each other with the shaft centers thereof inclined from a perpendicular direction by putting the first and second pinion holders 41, 42 closer to each other in inclined states so as to allow the first and second pinion gears 110, 120 to move up obliquely substantially at right angles to the shaft centers thereof. |
