PROBLEM TO BE SOLVED: To provide a frictional stirring and joining tool capable of easily and reliably adjusting the length of a tip pin only on the tool side, applicable even to a conventional friction stirring and joining device having no adjusting mechanism of the protrusion of a pin rod, and considerably reducing the working cost. SOLUTION: The frictional stirring and joining tool comprises a pin rod (20) having a male screw (24) forming a reverse screw to the rotation of the tool formed on an outer circumferential surface thereof and having a tip pin (23) with a tip part (21) inserted in a joining member, a tool body (1) having a shaft hole (10) which is opened in a shoulder part (4) and has a female screw (13) on an inner circumferential surface thereof with the pin rod protruding the tip pin from the shoulder part and screwed in the shaft hole in an axially advancing/retracting manner, and a first fixing means which is disposed on the tool body to fix the pin rod to the tool body. For example, the first fixing means is formed of a screw member (40) which is screwed in the radial direction from an outer circumferential part (2) of the tool body and abutted on the pin bar.
