Abstract
To provide a metal bonded product wherein a large bonding area can be provided to achieve high bonding strength and coaxial accuracy can be easily achieved needing no positioning jig. A first taper portionis formed on a side wall surface of the openingof the ring-shaped metal member, and multiple step-shaped bonding surfaces are formed thereon. An end of the cylindrical portionhas a second taper portionwith the same chamfer angle as that of the first taper portionof the ring-shaped metal member. The ring-shaped metal memberand the cylindrical metal memberare bonded to each other by press-fitting the cylindrical portion of the cylindrical metal memberin the openingof the ring-shaped metal memberwhile applying a current to cause the side wall portion of the cylindrical portion of the cylindrical metal memberand the multiple step-shaped bonding surfaces of the first taper portionto undergo plastic flow.
