PROBLEM TO BE SOLVED: To provide a planetary carrier capable of improving the rigidity as much as possible while securing an insertion space of a press-fitting tool. SOLUTION: In this planetary carrier 10 comprising first and second supporting walls 40, 42 supporting a plurality of pinions, a boss part 46 projecting from the first supporting wall 40, and a plurality of connection walls 48, 50 connecting the first and second supporting walls 40, 42 with each other, a reinforcement wall 44 is mounted to connect the plurality of connecting walls 48, 50 at their inner peripheral side, and a plurality of through holes 76 are formed on the reinforcement wall 44 in a state of axially penetrated, and positioned in a state that at least a part of them are positioned in a range where a distance from a shaft center is shorter than an inner peripheral radius of the second supporting wall 42 and larger than an inner peripheral radius of the first supporting wall 40. Thus a tip of the press-fitting tool 66 can be kept into contact with a radial inner side of the second supporting wall 42, and an inner side face of the first supporting wall 40 through the through holes 76 of the reinforcement wall 44.
