<p>PURPOSE: To prevent a pin from causing stress in the lateral direction to a wall of a hole by folding and overlaying both edges until flat surfaces meet by creating a fold at the central point after being formed as a long member with a hemispheric section. CONSTITUTION: A protruded part 20 consisting of a leg 22 and a leg 24 divided by a slit 26 and located at opposite sides are provided. A device 10 has a midpoint 28. On manufacture, a fold is created at the midpoint 28, and because of that fold, the folded device with a reduced section in a region 30 is provided. A pin 10 part spreading to right and left of the midpoint 28 is only an image of each other. Therefore, in case this device is folded with respect to the midpoint 28 and a pin or post 10' is generated, surfaces 18 in the right part and the left part meet and the pin 10' is combined only at the head part located at the very edge on the midpoint 28. Next, the slit 26 in the lateral direction extends perpendicular to the axis in the longitudinal direction of the pin or post 10'.</p> |
