Abstract
A friction stir welding apparatus includes: a welding tool; a spindle housing covering a spindle connected to the welding tool; a plurality of roll members provided on the spindle housing; and a guide rail for guiding the welding tool in a predetermined direction by contacting any of the roll members among the plurality of roll members and a guide surface of the guide rail. Further, the plurality of roll members is arranged in a manner that, when viewed from an axial direction of the welding tool, a distance from an axis of the welding tool to a position where one of the roll members is in contact with the guide surface is different from a distance from the axis of the welding tool to a position where another roll member is in contact with the guide surface.
