Plane scroll spring and curtain driving device
An embodiment of the present invention provides a plane scroll spring. A torque provided by a working section of a reed of the plane scroll spring is gradually reduced from an outer ring toward an inner ring of the plane scroll spring. The working section includes a first length section and a second length section connected to an inner end of the first length section. In the first length section, the torque decreases by a first decrement value per unit length from the outer ring toward the inner ring. In the second length section, the torque decreases by a second decrement value per unit length from the outer ring toward the inner ring. The first decrement value is less than the second decrement value.
