摘要：
A window body brake mechanism for non pull cord window blind includes a rolling-up unit including two coil spring winding wheels meshed together and a coil spring connected between the coil spring winding wheels, a transmission unit including two transmission gears respectively meshed with the coil spring winding wheels and two transmission cords respectively connected to the transmission gears, and a brake unit including an operating button having a braking portion disposed between the two coil spring winding wheels and so configured that when the operating button is operated into a press position, the braking portion is released from the coil spring winding wheels for allowing synchronous rotation of the coil spring winding wheels; when the operating button is operated into a release position, the braking portion is engaged with the coil spring winding wheels to stop the coil spring winding wheels from rotation.
