ことを特徴とするものである。<Means for Solving the Problems> In order to solve the above problems, a shield plate mounting structure of the present invention has a frame, a shield plate detachably attached to the frame, and the shield of the frame. A mounting plate fixed to the frame body with a gap inside the mounting surface of the plate, a mounting hole for a fixing bolt of the shielding plate provided in the mounting plate, and the frame body corresponding to the mounting hole. A through hole for a fixing bolt provided on the mounting surface of the shield plate, and a lower through hole having a size for inserting the head of the fixing bolt provided on the shield plate corresponding to the mounting hole and the through hole, and Insert the Daruma-shaped hooking hole, which consists of an upper locking hole that communicates with this insertion hole and is smaller than the head width, and the hooking hole of the shielding plate and the insertion hole of the frame, and tighten it to the mounting hole of the mounting plate. With a half-screw fixing bolt that is loosely screwed,
The fixing plate is locked in the cylindrical portion of the fixing bolt in a state where the fixing bolt is inserted into the hooking hole of the shielding plate and the insertion hole of the frame body and is screwed into the mounting hole of the mounting plate. It is characterized by that.

定ボルト３を抜く。As shown in FIG. 1 (d), it is the same as the conventional case that the shield plate 2 is provided with a daruma-shaped hooking hole 21. Then, as shown in FIGS. 1 (c) and 1 (e), a half-screw fixing bolt 3 is inserted in a position corresponding to the hook hole 21 of the frame body 1 of the switchboard.
11 is provided, and further, a gap, that is, the dimension A shown in FIG. 1 (c) is placed inside the attachment surface of the shielding plate 2, and the attachment plate 4 is fixed to the frame body 1 by welding or bolts. A mounting hole 41 is provided at a position corresponding to the hooking hole 21 and the insertion hole 11, and the half bolt fixing bolt 3 is inserted into the insertion hole 11 and screwed. Then, the head of the fixing bolt 3 of each half screw is inserted into the large diameter portion of the lower insertion hole of the hooking hole 21 so that the unthreaded portion of the fixing bolt 3 of each half screw, that is, the cylindrical portion is inserted into each hooking hole 21. Then, the shield plate 2 is attached to the frame body 1 of the switchboard by tightening the fixing bolts 3 of the respective half screws. When removing the shield plate 2, loosen the fixing bolts 3 of each half screw to remove the shield plate 2.
Lift up a little and pull out the fixing bolt 3 of each half screw from the large diameter part of each hooking hole 21.
〈考案の効果〉 取付穴の位置を遮蔽板の取付面より後に下げることによ
