To provide a method for producing a two piece wheel with a rim and a disk joined with a sufficient joining strength.

A disk 12 having a cylindrical joint 14 is inserted into a rim 10 provided with a cylindrical flange part 20 elongating to a direction separated from a design face 18 in the side opposite to the design face 18 on the peripheral part so that the outer circumferential face of the cylindrical flange part 20 is superimposed on the inner circumferential face of the cylindrical joint 14. Thereafter, to a region on the side of the design face 18 of the rim 100 in the superimposed part 22 of the cylindrical flange part 20 and the cylindrical joint 14, a pin 26 to be rotated at high speed is inserted so as to reach the cylindrical flange part 20 from the outer circumferential side of the cylindrical joint 14. They are moved relatively in a circumferential direction, so that the edge parts on the side of the design face 18 of the rim 10 in the superimposed part 22 are subjected to friction stir joining.
