To provide a shielding device that can improve safety while downsizing an operation device, reducing cost, and improving operability.SOLUTION: A shielding device of the present invention has an operation device 3, which enables shielding materials 11U, 11L respectively to be opened and closed by rotating multiple drive shafts 7R, 7F (or enables a shielding material 11 to be opened or closed by rotating a piece of drive shaft 7). The operation device 3 droops operation cords 13, 14, to which single-stage or multi-stage grip members are attached from a pair of operation pulleys 32, 34, and has a spiral spring 33, which applies energizing force to the rotation in the opposite direction to each other of the operation pulleys 32, 34 so as to roll up the operation cords 13, 14, respectively, and a rotation transmission shaft 36 and driven gear members 37, 38, which are configured as a rotation transmission mechanism to transmit the rotation of one of the operation pulleys 32, 34 that are made to rotate against the energizing force to the drive shaft 7F and the rotation of the other to the drive shaft 7F.SELECTED DRAWING: Figure 1
【課題】操作装置に係る小型化、低廉化及び操作性の向上を図りつつ、安全性を高めることができる遮蔽装置を提供する。【解決手段】本発明に係る遮蔽装置は、複数本の駆動軸７Ｒ，７Ｆの回転によって遮蔽材１１Ｕ，１１Ｌをそれぞれ開閉可能（又は１本の駆動軸７の回転によって遮蔽材１１を開閉可能）に操作するための操作装置３を備える。操作装置３は、一対の操作プーリー３２，３４からそれぞれ１段又は複数段のグリップ部材を取着した操作コード１３，１４を垂下させており、操作コード１３，１４をそれぞれ巻き上げるよう操作プーリー３２，３４に対して互いに逆方向の回転に付勢力を付与するぜんまいバネ３３と、当該付勢力に抗して回転させる操作プーリー３２，３４のうち一方の回転を駆動軸７Ｆに、他方の回転を駆動軸７Ｆに伝達させるための回転伝達機構として構成される回転伝達軸３６及び被動ギヤ部材３７，３８と、を有する。【選択図】図１
