In a blind with two shields, it is possible to perform different operations by operating one operating means and reduce the dimension of an operating device by reducing the number of parts. The operating device comprises an operating shaft 46 rotated upon receiving an operation force, a clutch 48 rotating integrally with the operating shaft 46 and axially sliding on the operating shaft 46, and a first transmission member 50 and a second transmission member 52 disposed at both axial sides of the clutch 48 to transmit driving force to a first driving shaft 54 and a second driving shaft 56, respectively. The sliding direction of the clutch 48 is determined by the rotational direction of the operating shaft 46, such that as the clutch 48 sliding on the operating shaft 46 is engaged with one of the transmission members 50 and 52, the rotation of the operating shaft 46 is transmitted to any one of the driving shafts 54 and 56 through one of the transmission members 50 and 52. |
