Claims

[Claims for Utility Model Registration] (1) An operating shaft disposed horizontally within a top box, a winding drum integrally rotatable and slidably fitted to the operating shaft, and a male thread of the winding drum. a lifting cord that is wound around a provided peripheral surface to raise and lower the slat; a bracket that is fixed to the top box and has a screw hole that engages with the male thread of the winding drum; and a bracket that is rotatable integrally with the operating shaft. a take-up drum cover fitted and axially positioned on the bracket,
A stopper is rotatably pivoted below the threaded hole on the end surface of the bracket on which the winding drum is screwed, and presses it upward, and a guide roll is attached to the stopper, and the guide roll moves up and down. A cord is hung therethrough, a claw is integrally formed at a position of the stopper in line with the guide roll and protrudes from the end surface of the bracket toward the screw hole, and a cylindrical portion coaxial with the screw hole is formed on the outside of the screw hole of the bracket. , a front end of the winding drum cover is rotatably fitted into the cylindrical part, a ratchet is formed at the front end of the winding drum cover, and when the claw and the ratchet are engaged, the lifting cord is rewound in a direction. An operating shaft rotation restraining device for a Venetian blind, characterized in that the device is formed to restrain rotation of the operating shaft of a Venetian blind. (2) Utility model registration No. 1, characterized in that a leaf spring is integrally formed on the stopper, a leaf spring receiver is provided on the bracket, and the stopper is rotated upward by the elastic repulsive force of the leaf spring.
