Kind Code:
A1
Abstract:
A blind operating device configured to be easily mounted to and removed from a head box.
A pulley (320) is provided with a power transmitting member (340), which rotates together with the pulley (320), so as to be exposed to the outside of a pulley case (81). The power transmitting member (340) is adapted to be removably connected to the input shafts of input bevel gears (32, 33) provided in an exposed manner to the outside of a head box (11). The configuration allows the pulley (320) and the pulley case (81), which rotatably contains and supports the pulley (320), to be collectively removed from the head box (11) side only by removing the power transmitting member (340) from the input shafts of the input bevel gears (32, 33). A tool and the like are not required.
