Abstract
A curtain body locating mechanism of a curtain with no cord mainly utilizes two separation and reunion units to control the locating effect when a curtain body is being spread or folded. The separation and reunion unit comprises an axle, two braking blocks, a separation and reunion wheel and two planetary gears. The two braking blocks are spaced apart and connected to the periphery of the axle so that a rolling groove is formed between the two braking blocks. The separation and reunion wheel is nested onto the axle and has an inner ring gear surrounding the two braking blocks. Each of the planetary gears is disposed within one of the rolling grooves and engaged with the inner ring gear of the separation and reunion wheel.
