Abstract
PURPOSE: To surely join parts even when the accuracy of finishing of the parts is lowered and to improve the reliability of the product, by inserting a projected piece into a hole or a notched part of a member, and by expanding the shoulder section of the projected piece with a punch, and then, by extending the expanded part over the marginal edge of the hole or the notched part.
CONSTITUTION: A hole 2a of the 2nd parts is put on a projected piece 3a of the 1st parts, and a staking punch 6 is pushed down while the top part of the projected piece is extruded from the upper surface of the hole 2. Then, in the first place, a punch section 7 contacts with the center of the projected piece 3a, expands the shoulder part 3a-s of the projected part 3a, and forms an expanded shoulder part 3a-s1. When the punch 6 is pushed down further and the punch section 7 retreats into a longitudinal groove 10 against a spring 9, another punch section 8 contacts the expanded shoulder part 3a-s1 and expands it, and then, forms an expanded shoulder part 3a-s2 of the 2nd stage. The expanded shoulder part 3a-s2 covers the marginal edge of the hole 2 and surely joins the hole 2 and the projected piece 3. Even when a hole 3, through which the projected piece is inserted, is a notched part, they are joined in the same way.
