A planetary carrier includes a plurality of pinion gears, a plurality of pinion shafts that are each inserted in the corresponding pinion gear, a first supporting plate that supports one end of each of the pinion shafts, a second supporting plate that supports the other end of each of the pinion shafts, and a plurality of bridge plates, one end of each of which is joined to the first supporting plate via a welding portion and the other end of each of which is joined to the second supporting plate via a welding portion and which connects the first and second supporting plates.

Planetary carrier and method for manufacturing the same

A manufacturing method for a joint part in which a first metal piece and a second metal piece are joined to each other by performing welding by irradiating a high-energy beam to a joint surface on which the first metal piece and the second metal piece face each other, the first metal piece including a first flow path for passage of a fluid provided at a specific depth from a surface on a side exposed to the high-energy beam, the second metal piece including a second flow path for passage of the fluid provided at a specific depth from the surface on the side exposed to the high-energy beam, and the first flow path and the second flow path being coupled to each other on the joint surface.
