Abstract
A window shutter actuation device includes a cord for driving window shutter slats to move, a retracting mechanism for winding an end of the cord away from the window shutter slats, a brake mechanism arranged between the retracting mechanism and the window shutter slats for controlling a retracting or releasing speed of the cord, and a power mechanism for driving the retracting mechanism to rotate to wind the cord. The retracting mechanism includes a frame, a reel rotatably mounted to the frame for winding the cord, and a wheel arranged outside and adjacent to an end of the reel. The end of the cord wound on the reel passes about the wheel and then extends to the brake mechanism after extending from the reel.
