<p>PROBLEM TO BE SOLVED: To drive a system with a simple configuration.SOLUTION: A movable eaves system comprises: a plurality of movable eaves C; and an elevation mechanism B capable of vertically moving and stopping the movable eaves. The elevation mechanism includes; at least one rotary body B3; a single first drive device B1 for driving the rotary body; and connection cords B4-A, ..., wound within a certain range of the rotary body in an axial direction while fixing proximal ends thereof to the rotary body and connecting distal ends of cord portions drooped from the rotary body to the movable eaves. The connection cords are provided as at least a pair of connection cords for each of the movable eaves, distal ends of the pair of connection cords are connected to inner end sides and outer end sides of the movable eaves, and the rotary body is formed in such a manner that a radial length from a rotation axis to a circumferential surface is continuously changed in the axial direction within a certain range in the axial direction.</p> |
