Abstract
A stringless curtain structure has a curtain body, a string rolling mechanism and two breaking units, wherein weight of a spring in the string rolling mechanism and a weighted lower beam is balanced, the user can push/pull the weighted lower beam to control a curtain of the curtain body to eliminate the exposure of the string, so little children would not play with the string to lead to dangerous situation. Furthermore, the breaking unit is disposed at each sides of the string rolling mechanism, so when the curtain needs to be positioned, the friction between the string and the breaking units can be used to enhance the precision of the positioning of the curtain body.
