To improve installing workability of a suspending device by constituting a frame body of a main frame and an auxiliary frame, installing a lifter in the main frame, and suspending/supporting a solar radiation shielding material by the auxiliary frame in the suspending device having the lifter to lift the solar radiation shielding material in the frame body to suspend/support the solar radiation shielding material.
A wood shaving screen has a frame body 1 to suspend/support a screen material 2 and a screen balance 3, but the frame body 1 is composed of a main frame 4 installed in a window frame and an auxiliary frame 5. A winding shaft 6 is rotatably supported by the main frame 4 to suspend/support plural lifting cords 7 from this winding shaft 6. The lower end parts of the lifting cords 7 are inserted into guide rings installed in a plurality in the vertical direction on the screen material 2 to be installed in the lower end part of the screen material 2. The auxiliary frame 5 is supported by the main frame 4 so as to be freely attachable by locking the locking part 10 formed in the auxiliary frame 5 fastened/installed with the end part of the screen material 2 and the screen balance 3 on an upward projecting locking piece 9 by forming it in the front part of the main frame 4.
