Original Abstract Submitted

at a position of a depth of the first predetermined value from the surface of the gear portion, a surface treatment that satisfies a range of a required hardness defined in advance of the gear portion is performed. a surface treatment is performed at a depth of a second predetermined value from a surface of a bearing portion, the surface treatment satisfying a required hardness in a range prescribed in advance for the bearing portion. since the second predetermined value is deeper than the first predetermined value, the hardness distribution is made different between the gear portion and the bearing portion. the required hardness in the gear portion and the required hardness in the bearing portion are respectively satisfied.
