Abstract
In a friction spot joint structure, a first plate member is pressed against a second plate member by using a rotary tool and a receiving member. A concave portion is formed by a rotating pin portion of the rotating tool, with an interface between the first plate member and the second plate member remained. In this time, the first and second plate members are allowed to plastic-flow, so that an annular bulging portion of the second plate member raised into the first plate member is formed around the concave portion.
