PROBLEM TO BE SOLVED: To provide a balance weight in which a bottom cord can be separated from the balance weight without damaging the balance weight when the bottom cord is trampled on.SOLUTION: A balance weight of the present invention is attached to a lower end of a slat of a vertical blind and attached to a bottom cord, and includes a body part attached to the slat, and a connector attached to the bottom cord and slidably connected to the body part. One of the body part and the connector includes a male rail part having a wide part at the tip side and having a narrow part narrower than the wide part at a base end side. The other of the body part and the connector includes a female rail part engaged with the male rail part and capable of sliding movement to the male rail part. In at least one of the male rail part and the female rail part, a first locking convex part is provided that prevents the separation between the connector and the body part in the normal use, and separates the connector from the body part in the lower direction by the slide movement when the force exceeding a threshold value is applied to the connector. |
