Claims

[Claims for Utility Model Registration] 1. An operating body in which an operating arm and a locking arm protrude from the shutter guide rail, and a release position in which the operating arm intersects with the descending locus of the guide body provided at the side edge of the shutter curtain. The guide body is always biased toward the side, and is swingably provided so that the guide body presses the actuating arm as the shutter curtain descends, changing the position to the lock position side. When the lock arm transforms to the lock position side, it is pressed by the lock arm and retracts, allowing the lock arm to pass over, and restricts the upward movement of the lock arm that has passed over, making the lock weight body that locks the lock freely swingable. A locking device for an architectural shutter, characterized by the following: 2. The above-mentioned locking weight body has a substantially fan-shaped top that is swingably supported, and the bottom end side of the locking weight body faces the transformation locus of the locking arm, so that the locking position side of the locking arm is In the transformation, the lock arm presses the side of the lock weight from above to retract the lock weight, and the lock arm that has passed the lock weight comes into contact with the hem end of the lock weight. A locking device for an architectural shutter according to Claim 1 of the Utility Model Registration Claim, characterized in that the locking device is configured to restrict upward movement.
