Claims

[Scope of utility model registration request]

In a hole-cutting jig for a flange of a rectangular waveguide component made of precision casting such as Lost Wax, a piece on the long side and a piece on the short side are positioned so that the reference is on the line of symmetry of the inner cross section of the waveguide. A jig plate has a guide bush that can guarantee the standard hole position limit based on the piece, and the pieces on the long side do not fall out, and the pieces on the long side and the pieces on the short side are on the jig plate. A spring between the piece on the long side and the back cover, a spring between the piece on the long side and the piece on the short side, and a spring between the piece on the long side and the short side so that each piece can be moved using the square hole as a guide. A rectangular waveguide flange hole jig characterized by having screws for connecting side pieces, a presser foot and tightening screws for holding a rectangular waveguide component, and jig feet.
