Abstract: A cordless roller blind includes a roller tube, a blind fabric wound around the roller tube, and at least one brake device. A coil spring is arranged in the roller tube, and the torsion of the coil spring changes as the roller tube rotates. The torsion force of the coil spring, the friction force provided by the brake device and the weight of a hanging portion of the blind fabric are mutually balanced, so that the blind fabric remains stationary at any position without an external force. When the external force pushes the blind fabric to move upward, pressure acting on the brake device decreases as the external force offsets the weight of the blind fabric, and the friction decreases accordingly, and the torsion force of the coil spring drives the blind fabric to wind up.
