PURPOSE: To improve the rigidity of a carrier of a planetary gear set combining and supporting short pinions and long pinions and improve the durability of the planetary gear. CONSTITUTION: This planetary carrier supports a plurality of short pinions P1 and long pinions P2. As for a first support wall 11 supporting one ends of each short pinion and long pinion, a second support wall 21 supporting the other end of each short pinion, and a third support wall 22 supporting the other end of each long pinion, the first support wall and the second support wall is connected by a first connecting wall 23, the second support wall and the third support wall are connected by second connecting walls 24 formed into a pair by diametrically sandwiching each long pinion, and the second connecting walls are mutually connected by a third connecting wall 25 in either one of diametrically inside or outside of each long pinion relative to the carrier central shaft.
