Claims

[Claims for Utility Model Registration] (1) In a mounting structure in which a first member and a second member are overlapped and fixed by a set screw, the set screw is inserted into the first member. A mounting hole is formed, and a positioning protrusion is formed near the mounting hole, and the positioning protrusion has a shape that has an apex at the center and gradually decreases in height toward the periphery. A mounting hole into which the set screw is inserted is formed in the second member, and the first member and the second member are overlapped near the mounting hole so that the mounting holes are aligned. The mounting structure is characterized in that a positioning recess having a diameter smaller than a maximum diameter of the positioning projection is formed at a position facing the positioning projection. (2) In the mounting structure according to claim (1), at least one of the mounting holes formed in the first member and the mounting hole formed in the second member extends from the edge of the member. It is characterized by being connected to a cut groove.
