[Object] Provided are a press-molded product in which the plank pieces can be appropriately matched with each other and the weight of the product is not increased even when the plank pieces can be appropriately matched with each other, and a method of manufacturing the same. [Solving Means] The present invention is a press-molded product () formed by bending a blank (B) to divide the blank into a first plank piece () and a second plank piece () with a bending portion interposed therebetween and making the first plank piece and the second plank piece come into contact with each other through the bending. The first plank piece and the second plank piece include punching portions () formed by punching the blank, and a first rising portion () and a second rising portion () formed by raising the rims of the punching portions. There is provided a positioning portion () that positions the first plank piece and the second plank piece by engaging the first rising portion of the first plank piece with the second rising portion of the second plank piece.

Press molding and manufacturing method therefor

[Problem] To provide a suspension link having excellent reliability in strength or the like of a coupling portion of the suspension link while being inexpensive. [Solution] The present invention relates to a production method for a suspension link () having a tire coupling portion () that rotatably couples a tire to a suspension and a suspension coupling portion () that is coupled to a sub-frame member constituting the suspension, the method including: a bending process in which a plate is bent, a bent portion of the bent plate is formed into a hollow shape, and the hollow shape is used as one of the tire coupling portion and the suspension coupling portion; and an edge bending process in which an outer peripheral edge portion of the plate is bent prior to the bending process. The outer peripheral edge portion of the plate is bent by the edge bending process, the outer peripheral edge portion of the plate including an area from an arm () to a bent portion ().
