<p>PROBLEM TO BE SOLVED: To make it possible to prevent disconnection and damaging accident of a conductive cord by causing holders to have ringlike insertion holding parts plane and thin in the folding direction of a shutter, and movable in the direction of insertion of the conductive cord in obedience to it, and making integrated holder bodies out of corrosion-resisting strong material. SOLUTION: Insertion holding parts 2 are composed of substances flat in the folding direction of a shutter in the point of constitution, or rings being plane and thin substances, and move in obedience to the rotation of fitting parts 1 fitted to pole braces in the direction of insertion of a conductive cord. The fitting part 1 of each fitting and holding device and its insertion holding part 2 are integrated and fixed in the perpendicular direction at a welded part 3, and the fitting and holding device is made of corrosion-resisting strong material stainless steel, other steel materials anti-corrosion-processed, and so on. Consequently, it becomes possible to prevent the cord from being disconnected and damaged since the cord is held in obedient to the directions of insertion and bending of the cord, even by the folding action of the shutter.</p> |
