The slider 21 is driven in the holder 20 by the driving mechanism by operating and rotating the rotary gear 22, and thereby the ladder tape 10 for locking the slider 21 is pulled in the holder 20 or delivered to the outside of the holder 20, so that the length of the ladder tape 10 is adjusted. That is, a height of the bottom rail suspended-supported by the ladder tape 10 is adjusted in a horizontal blind. |
