Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve an outward appearance of an appearance, without risk of contacting with a burr formed in an opening, even if the opening is formed by punching processing.SOLUTION: A shutter curtain is formed by connecting a plurality of slats 9 of combining a fixed blade 15 and a movable blade 16 in the vertical direction. A padding-like projection part 17 extending in the horizontal direction is formed in a plurality at a predetermined interval in the vertical direction on the outdoor side of the fixed blade 15. When forming an opening 14 by punching by a metal mold on the outdoor side from the indoor side in a flat part between the projection parts 17 of the fixed blade 15, a burr is caused in a peripheral edge part of the opening 14. The movable blade 16 can be opened-closed to the fixed blade 15. The projection part 17 of the fixed blade 15 is higher than the burr, and when touching an outdoor side surface of the fixed blade 15 by a hand, a finger is prevented from reaching the opening 14 by the upper-lower projection parts 17, and the finger does not touch the burr. There are no projection part and burr on an indoor side surface of the fixed blade 15, and the outdoor side projection part 17 and the burr can be prevented from visual observation by the movable blade 16.SELECTED DRAWING: Figure 6
