Claims

[Scope of utility model registration request]

A worm gear is fitted via a clutch mechanism to a hexagonal bar installed longitudinally inside the head box to operate the ladder cord for opening and closing the blinds, and the worm is fixed to the upper end of the operating shaft to rotate the slat. In the blind opening/closing device with a stopper, which has an opening/closing mechanism and is attached with a stopper device for controlling rotation of a hexagonal bar in a head box or a ladder cord drive section housed in the head box, the clutch mechanism is connected to one side of the blind opening/closing device. The center of the joint is inserted into a hexagonal rod, and the end of the joint in the direction of connection is provided with a notch that expands in the direction of connection, and a prismatic convex part with a hollow center is formed of an elastic body. The joint has a hexagonal rod rotatably passing through the center thereof, and a wheel having a prismatic recess that fits into the convex portion formed on one of the joints at the end in the connection direction, and a wheel in the non-connection direction. The blind opening/closing device with a stopper is characterized in that it is provided with a worm gear that meshes with the operating shaft.
