Abstract:
A method of manufacturing a liquid-cooled jacket, includes a preparation step which includes placing a sealing body on a stepped portion to allow a step side surface and a sealing-body side surface of the sealing body to butt each other, and a primary joining step which includes allowing a primary joining rotary tool to move once around the sealing body, while moving the rotary tool along a butted portion formed in the preparation step, to carry out friction stir welding. The primary joining step includes employing the primary joining rotary tool provided with a stirring pin having a length dimension greater than a thickness dimension of the sealing body, and carrying out friction stirring with only the stirring pin being brought into contact with a jacket body and the sealing body.

Claim (Index 1):
A method of manufacturing a liquid-cooled jacket which is composed of a jacket body having a bottom portion and a frame-shaped side wall portion provided to stand on the bottom portion, and a sealing body which seals a recess of the jacket body, and allows heat transport fluid to flow in a hollow portion formed by the jacket body and the sealing body, the method comprising:\n a preparation step which includes placing the sealing body on an end surface of the side wall portion to allow the end surface and a back surface of the sealing body to overlap with each other; and a primary joining step which includes allowing a rotary tool to move once around the recess, while moving the rotary tool along a first overlapped portion overlapped in the preparation step, to carry out friction stir welding, wherein wherein the primary joining step includes carrying out friction stirring with only stirring pin being brought into contact with both of the jacket body and the sealing body, or only the sealing body.
