Device for elevating solar-radiation-shielding material
According to the present invention, a device for elevating a solar-radiation-shielding material is provided in which (1) a second elevating cord is hung down while being guided by a first winding-shaft-side guide member, and the first winding-shaft-side guide member is disposed at a position further away in a front-rear direction from a second winding shaft than a disposition where a distance between a second common tangent, passing through the upside of the second winding shaft and the upside of the first winding-shaft-side guide member, and a first elevating cord wound around the first winding shaft equals the diameter of the second elevating cord, and (2) the first elevating cord is hung down while being guided by a second winding-shaft-side guide member, and the second winding-shaft-side guide member is disposed at a position further away in a front-rear direction from the first winding shaft than a disposition where a distance between a first common tangent, passing through the upside of the first winding shaft and the upside of the second winding-shaft-side guide member, and the second elevating cord wound around the second winding shaft equals the diameter of the first elevating cord; or the first and second elevating cords are wound around the first and the second winding shafts, respectively, by turning the first and second winding shafts from the outside toward the inside.
