Mounting hole processing jig and mounting hole manufacturing method using mounting hole processing jig

摘要

Provided are a mounting hole processing jig capable of easily manufacturing a mounting hole and a method of manufacturing a mounting hole using the mounting hole processing jig. In the mounting hole processing jig (100) for processing the cut portion (CF41) provided in the mounting hole of the target sheet (CL41), the jig body (1) having an outer surface that can be inserted through the mounting hole, Since it has a folding means (2) for applying a force from the side surface to the outside and folding the cut portion (CF41) outward, the cut portion (CF41) can be folded all at once. Hole processing can be facilitated.
