Claims

[Scope of utility model registration request]

(1) A string receiving roller is held on the front surface of a block-shaped case that houses therein a rotating shaft end for tilting the slat, a rotating tube end linked to the operating tube, and a gear mechanism for transmitting power between the surface rotating parts, In a blind operating device in which one end of a slat lifting string is pulled out downward through the roller, the rotating tube and the operating tube, a hollow gear having internal teeth and forward bevel teeth is held on the rear surface of the interior of the case, and the hollow gear is A blind transmission gear device in which a pinion attached to the rotating shaft is engaged with internal teeth of the gear, and an upward bevel tooth formed at the upper end of the rotating tube is engaged with the bevel teeth.

(2) A blind transmission gear device in which a small gear is engaged with the top of the internal teeth of the hollow gear to form as wide a gap as possible between the rotating shaft for tilting the slat and the string receiving roller.
