Abstract
A planetary carrier includes: a first plate and a second plate which pivotally support planetary gears between opposing plate surfaces of the first and second plates such that the planetary gears are located on a circular path so as to be spaced apart from each other, the circular path being a path of rotational centers of the planetary gears; and coupling plates which are located between the opposing plate surfaces, are spaced apart from each other in a circumferential direction of the circular path, couple the first plate and the second plate, and are coupled to external members at positions away from the planetary gears in the circumferential direction. The coupling plates are coupled to the external members at an outside of the circular path in a radial direction. Each of the coupling plates is coupled to the first plate and the second plate only at a first side in the circumferential direction.
