PURPOSE: To make work easy by providing a magnet-housing part to an optional face of an iron fixture approximately in L shape, and by making the iron fixture attractive to an iron material with a permanent magnet housed in the magnet- housing part.
CONSTITUTION: A recess 2 housing a magnet therein is provided to one face of an angle piece 1, and a permanent magnet 3 is installed to the recess 2 with slight gaps provided to the sides and the underside. Then, the angle piece 1 is put, being strongly attracted, to a specified position on an iron material with positioning made with a positioning part 4 and connected with bolts through bolt holes 5. Therefore, an worker is not required for holding the metal fixture while executing work, and work can be executed easily.
