    Abstract: A support pin mainly composed of a fitting part fitted into a hole in a workpiece, a flange part (head part) formed at one end of the fitting part, and a projected shaft formed at the other end of the fitting part. The fitting part is larger in diameter than the projected shaft, and an annular recess is formed in the fitting part. A portion of the fitting part is formed as a staking part, and the portion is located on the outside of the annular recess. The annular recess has a bottom part and a tilted inner peripheral surface. When the support pin is held and pressed by both the die and the punch of a press device, the flange part digs into the front surface of the workpiece and the staking part digs into the rear surface of the workpiece.
