Abstract: A friction stir spot welding device capable of connecting to-be-processed objects using friction heat between the overlapped objects and a rotation tool is provided. In the friction stir spot welding device, a driver for driving the rotation tool is not installed on the same shaft as the rotation tool, and a driving force for moving the rotation tool in a vertical direction is transmitted through a feed screw and feed nuts engaged therewith. Accordingly, it is possible to reduce the load of the friction stir spot welding device and accurately control the height of the rotation tool.
