Claims

[Claims for Utility Model Registration] 1. A first flange portion having a through hole, a second flange portion facing the first flange portion and having a through hole, and fitting into the through hole of the first flange portion. The first fitting part, the second fitting part that fits into the through hole of the second flange part, and the first fitting part and the second fitting part are connected and break when a stress above a certain level is applied. a mechanical fuse consisting of a connecting portion; a first retaining member that seals the through hole from a side of the first flange portion opposite to the side facing the second flange portion; and a first retaining member of the second flange portion. a second retaining member that seals the through hole from the side opposite to the side facing the first flange portion; an overload protection device comprising: a first fitting portion of the mechanical fuse and the first retaining member; An overload protection device characterized in that the second fitting portion of the mechanical fuse and the second retaining member are each fixed with bolts. 2 Fixation with the bolt is achieved by providing a screw hole in the first and second fitting portions of the mechanical fuse, and further providing a through hole in the first and second retaining members, inserting the bolt into the through hole, and then inserting the bolt into the through hole. An overload protection device according to claim 1, which is screwed into a screw hole in a joint.
