The lifting / lowering cord 18 is suspended from the take-up drum 22, and the lower end of the lifting / lowering cord 18 passes through the cord ring 15 in the vertical direction along the rear surface of the front fabric 14, and its end is at the lowest position. The cord ring 15 is connected.

  Further, a back fabric 32 as a second shielding material can be hung on the rear wall surface 12b of the head box 12 by detachable coupling means 34 (34a, 34b) such as a hook-and-loop fastener. An insertion hole 32a is formed in the upper portion of the back fabric 32, and a plurality of cords are formed on the rear surface of the back fabric 32 with a predetermined interval in the width direction and a predetermined interval in the vertical direction. A ring 33 is attached.

  A rear rail portion 12c is formed integrally with a lower portion of the rear wall surface 12b of the head box 12, and a manual opening / closing device 38 is detachably attached to the rear rail portion 12c. The manual opening / closing device 38 is attached to a cord insertion ring 40 attached to the rear rail portion 12c at predetermined intervals, a plurality of lifting cords 36 inserted through the cord insertion ring 40, and one end portion of the rear rail portion 12c. And a stopper 42 for switching between locking and releasing of the lifting / lowering cord 36. One end side of the lifting / lowering cord 36 is dropped after passing through the corresponding cord insertion ring 40, passed through the insertion hole 32 a of the back fabric 32, and then moved up and down the cord ring 33 along the rear surface of the back fabric 32. The end of the lifting / lowering cord 36 is connected to the cord ring 33 located at the lowermost position. Further, the other end side of all the lifting / lowering cords 36 is dropped after passing through the stopper 42, and its end is coupled to the knob 44.

  In the solar shading device 10 configured as described above, when an operation unit (not shown) such as a remote controller is operated and the motor drive circuit rotates the motor 26 in one direction by a command signal from the operation unit, the shaft 24 The winding drum 22 winds the lifting / lowering cord 18 by rotating in the direction. As a result, the lower end of the lifting / lowering cord 18 is raised, and the front fabric 14 is folded and folded from below. Thus, the front fabric 14 rises and the back fabric 32 can be exposed.

  Further, when the operation unit is operated and the motor drive circuit rotates and drives the motor 26 in the opposite direction by a command signal from the operation unit, the shaft 24 rotates in the opposite direction, and the winding drum 22 winds the lifting / lowering cord 18. solve. As a result, the front fabric 14 descends while unfolding from above, and the back fabric 32 can be covered. In this way, the front fabric 14 can be opened and closed electrically.

  On the other hand, when operating the back fabric 32, the operation knob 44 is moved slightly downward to release the stopper 42, and then pulled downward, the lower end of the lifting / lowering cord 36 rises and the back fabric 32 is folded from below. I can get it. Thus, the back fabric 32 rises. If the front fabric 14 is also raised, the opening to which the apparatus 10 is attached can be opened.

  When the operation knob 44 is moved slightly downward to release the stopper 42 and then the force is released from the operation knob 44, the back cloth 32 and the weight of the weight bar attached to the lower end of the back cloth 32 cause the back cloth 32. Can be lowered while expanding from above, covering the opening to which the apparatus 10 is attached. In this way, the back fabric 32 can be opened and closed manually.

  For the front fabric 14 and the back fabric 32, the fabric that is electrically opened and closed may be more frequently opened and closed. For example, if the front fabric 14 is made of a highly light-shielding fabric and the back fabric 32 is made of a low-light-shielding material, for example, a lace fabric, the fabric with a low light-shielding property is often closed at all times, so it is almost necessary to operate it.
