Abstract
There is provided a friction stir spot joining device in which a pin can be simply and surely caused to come in or come out from a tip end of the joining tool by driving a pin extraction motor. The friction stir spot joining device softens and stirs works to be joined by frictional heat generated by the rotation of a pin so as to perform spot joining and is provided with a stirring motor for rotating a joining tool having a pin, and a pressure application motor for linearly driving the joining tool. The friction stir spot joining device further has a pin extraction motor which is disposed at the rear of a stirring motor on the same axis line as the stirring motor and integrated with the stirring motor.
