機器用シールド。[Claims for Utility Model Registration] (1) It is divided into a ring-shaped first shield member and a ring-shaped second shield member, and the first shield member is attached to the main body of the device through a shield mounting plate. connection bolts are installed at intervals in the circumferential direction on the coupling surface of the first shield member to the second shield member, and the coupling bolts of the second shield member to the first shield member are fixed to A gourd-shaped elongated hole in which a large-diameter hole and a small-diameter hole are connected is provided in the surface so as to correspond to each of the connection bolts of the first shield member, and the longitudinal direction of the hole is directed toward the circumferential direction. The second shield member rotates the second shield member in the circumferential direction by passing the head of each of the connecting bolts of the first shield member into each of the large-diameter holes, so that the head of each of the connecting bolts is inserted into the second shield member. A shield for an electrical device having a structure in which the shield is connected by being transferred to a small-diameter hole portion, wherein a damping resin film is interposed between both coupling surfaces of the first and second shield members. Shield for. (2) A spacer plate is interposed between the mutual bonding surfaces of the first shield member and the second shield member at intervals in the circumferential direction, and the resin film is interposed between the spacer plate and the bonding surface. 2. The shield for electrical equipment according to claim 1, wherein the shield is interposed between the shield and the shield.
