ある。(Operation) The technical means operates as follows. That is, by welding a semi-finished drive plate to a ring gear, distortion occurs on the surface of the drive plate. The mounting part of the drive gear to the engine, where this distortion has occurred, is formed by press working, and the distortion caused by drive plate welding is absorbed, and the mounting part is formed and drilled with correct dimensional accuracy. There is no distortion at all, there is no lateral runout of the drive gear, and it is possible to manufacture a drive gear with excellent quality assurance.
