Abstract
Provided is a joint component manufacturing method for reducing occurrence of burrs upon bonding between a first member having a hole and a second member having a shaft portion and firmly bonding both members. In the method for manufacturing a joint component, a hole-side weak press-fit portionis formed at a holeof a flat plate ring-shaped first member. Moreover, each of a shaft-side weak press-fit portionand a shaft-side strong press-fit portionis formed at a shaft portionof a cylindrical second member. The hole-side weak press-fit portionand the shaft-side weak press-fit portionare defined by a first weak press-fit interference Lwformed thinner than a first strong press-fit interference Ls. The shaft-side strong press-fit portionis defined by a first strong press-fit interference Lsas the minimum necessary press-fit interference for electric resistance welding upon electric resistance welding between the holeand the shaft portion
