Abstract
In a frictional spot joining where plural metal members lapping over are jointed with a joining device comprising a rotating tool, a receiving tool disposed on a rotational axis of the rotating tool and a drive device to rotate and move the rotating tool in a pushing direction, a holding member is provided on a side of the receiving tool, which has a restriction portion to restrain a movement of the receiving tool in a direction perpendicular to the rotational axis, and the joining device is moved by a moving device such that the receiving tool is disposed at the restriction portion. Accordingly, the rotational runout of the rotating tool can be restrained effectively with a simple structure of a properly small-sized rotating tool and receiving tool.
