Method for Manufacturing Liquid-cooled Jacket
11 Jan 24
The present invention is characterized by including a primary joining process to perform friction stirring to a first butted portion by moving a stirring pin one round around a sealing body with a predetermined depth along a set moving track set at an inner position relative to an outer peripheral side face in a state that only the stirring pin of a rotary tool being rotated is inserted into the sealing body and that an outer circumferential face of the stirring pin is slightly in contact with a step side face of a peripheral wall step portion.

A rotary tool includes: a main body having a fixed unit and a rotary shaft; a stirring pin rotatable and movable relative to an axial direction of the rotary shaft, and inserted into a joint member to perform friction stirring; and a shoulder that is arranged on the main body so as not to receive a rotary force from the main body but to be movable relative to the axial direction of the rotary shaft, and that presses the joint member while in contact with the joint member, wherein the stirring pin and the shoulder are mounted to form an assembly so as to be relatively movable and to move integrally in the axial direction of the rotary shaft, and the rotary tool further includes a first elastic member that biases the assembly toward a distal-end side of the stirring pin relative to the axial direction of the rotary shaft.
