PROBLEM TO BE SOLVED: To provide spot friction welding equipment which, when a plurality of materials to be welded are welded by spot friction welding, suppresses a variation in the indentation amount of a rotary tool to the materials to be welded thereby stabilizing welding quality more. SOLUTION: The spot friction welding equipment is provided in which the plurality of materials to be welded are superimposed, then, while rotating a rotary tool, the distal end part of the rotary tool is indented from one direction side of the materials to be welded, and, by frictional heat generated by the indentation of the rotary tool, the materials to be welded are softened and are plastically fluidized, thus the plurality of materials to be welded are welded, and the spot friction welding equipment is characterized in that it is provided with a regulation member which is turnably arranged coaxially with the rotary tool, also is fixed in the axial direction of the rotary tool, and when the distal end part of the rotary tool is indented to the materials to be welded, abuts against the surfaces of the materials to be welded in the vicinity of their joint and regulates the indentation amount of the distal end part in the rotary tool to the materials to be welded.
