Claims

[Scope of utility model registration request]

The main body of the shutter slat is made into a flat plate, and a male joint is created by integrating an arcuate protrusion protruding rearward from the upper end with a locking edge arranged perpendicular to the main body and protruding forward and backward. An inward bent edge is formed in a direction perpendicular to the main body on an arcuate protrusion projecting rearward from a position slightly above the lower end of the main body; A female joint is formed by forming a fan-shaped protrusion with a gap in between and whose upper surface is at the same height as the inwardly bent edge, and a semicircular cross section near the position where the main body and the fan-shaped protrusion intersect perpendicularly. a rounded protrusion is formed at the front end of the locking edge, and the protrusion is fitted into the concave part of a female joint and a male joint of vertically adjacent shutter slats. A metal shutter characterized by being locked in place.
