方向へ流れやすくなる。The cavity 25 is provided with a central protrusion 29. The rivet 1 pressed by the punch is the leg 6
While being penetrated into the member to be fastened, the portion of the member to be fastened is deformed so as to project into the cavity 25. Since there is a central protrusion 29 in the center of the bottom surface of the cavity 25, when the rivet 1 is driven into the member to be fastened, the legs 6 of the rivet 1 hit the central protrusion 29 and cannot go straight down. ,
It opens while opening outward in the radial direction. In this way, since the central portion projection 29 is provided, the leg portion 6 of the rivet penetrates the fastened member while expanding radially outward. Therefore, the connection strength of the members to be fastened is increased. The angle A of the top of the central protrusion 29 is 90 ° or more and 160 ° or less. When the angle A is in this range, the material flow of the member to be fastened at the time of fastening is improved. The top of the central protrusion 29 is preferably spherical with a radius B. The spherical shape facilitates the material of the member to be fastened to flow outward.

にキャビティ25の中央方向へ向かって流れる。A substantially cylindrical outer wall 27 is formed in the cavity 25. If there is the outer wall 27, the material of the fastened member is the outer wall.
Flow upwards along 27. To create an upward flow, the inner diameter D of the upper end of the outer wall 27 is preferably not too large compared to the outer diameter of the rivet leg. As an example, the upper inner diameter D of the outer wall 27 is as follows. Upper inner diameter D of outer wall = outer diameter of leg of rivet + thickness of die-side fastened member × 4 The material of fastened member that flows upward along the outer wall 27 further flows toward the center of the cavity 25.

部Ｕが形成される。The cavity 25 has an outer wall 27. The material of the punch-side and receiving-side fastened members flows outwardly downward (I direction) along the central projection 29, and further, the fastened member material flows along a curved surface passing through the bottom portion 35 of the cavity 25. It changes its direction and flows upward along the outer wall 27. The fastened member is pushed from above by a rivet. The portion of the member to be fastened that is in contact with the outer peripheral portion of the cavity of the die is crushed between the die and the die by rivet driving, and is work hardened (H portion). Therefore, the material of the member to be fastened that has flowed upward along the outer wall 27 cannot move further upward, and flows toward the center of the cavity 25 (direction II). As a result, the member to be fastened on the receiving side has a shape that is narrowed down at the top, forming the convex portion 8 and forming the undercut portion U.
