1. A method of manufacturing a power transmission device, the method comprising:
forging to form a planetary carrier plate:
sintering to form a planetary carrier:
joining the planetary carrier plate to the planetary carrier by brazing the planetary carrier plate to the planetary carrier at support parts arranged in a circumferential direction at a peripheral edge part of the planetary carrier so that the planetary carrier plate is fixed to face the planetary carrier on a side of the planetary carrier where a pinion gear is positioned;
sintering the planetary carrier plate and the planetary carrier after brazing;
forming a pinion shaft hole for mounting a pinion shaft that constitutes the pinion gear in the planetary carrier plate and the planetary carrier;
forming dog teeth integral with the planetary carrier plate; and
performing high-frequency quenching on the dog teeth of the planetary carrier plate.
