摘要： A member joining structure for a differential device, the member joining structure includes a ring gear including a helical tooth extending in a rotation axis direction; a differential case that is rotated with the ring gear; and a first support that is disposed in a first position at a back surface corresponding to one end of a rotation axis of the ring gear and that connects the differential case and the ring gear, and a second support that is disposed in a second position at a back surface corresponding to another end in the rotation axis direction of the ring gear and that connects the differential case and the ring gear; wherein the first support and the second support are spaced apart from each other with a cavity therebetween.

摘要： 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.
