Claims

[Scope of utility model registration request]

The locking end of the fixed key bar protrudes from one end of the baseboard extending in connection with the lower end of the shutter, and the lock end of the fixed key bar is slidable in the width direction within the baseboard directly above the fixed key bar, and both ends are attached to both sides of the baseboard. A slide key bar inserted so as to be freely protrusive and retractable from one end is elastically biased to constantly give a habit of the upwardly slanted end protruding in line with the lock end and at the same time the other lock end receding into one end of the baseboard. On the other hand, when the shutter is completely lowered, an electric key holder that engages with the lock end of the fixed key bar when the lock is locked is installed near one side of the shutter at a height facing directly above the upwardly slanted end. A fixed key holder for locking the lock end of the slide key bar at a height position corresponding to directly above the electric key holder is provided near the other side of the key holder main body, facing each other across the shutter. A shutter locking device that can be set.
