Claims

[Claims for Utility Model Registration] Consisting of a shaft member 1 and a fitting member 6, the shaft member 1 has upper and lower flanges 2 and 3 for regulating the distance formed at an appropriate interval vertically, and the upper flange. An engaging body 4 is formed above the lower flange 3, and is formed above the lower flange 3, and shrinks due to external pressure when pushed into the insertion hole, expands due to elastic restoring force and engages with the outer edge of the hole after passing through the insertion hole. The fitting member 6 has a cylindrical shape with a large-diameter flange 6a at the upper end, and has a plurality of grooves 6c in the cylindrical portion 6b. A fixing device for an upper PC board and a lower PC board, which is formed so that the diameter of the lower part increases by inserting the upper PC board and the lower PC board. The device for fixing an upper PC board and a lower PC board according to item 1, wherein the insertion pin 5 has a large diameter at its tip. The upper PC board and the lower P according to the above item, in which the inner diameter of the fitting member 6 is reduced toward the lower end.
C plate fixing device. The device for fixing an upper PC board and a lower PC board according to any one of the items 1 to 1, wherein the shaft member 1 and the fitting member 6 are made of a synthetic resin material such as nylon 66 or polyamide.
