Abstract: Provided is a shielding device comprising a constant load unit, wherein it is possible to commonize component members across different device specifications. This shielding device comprises a drive shaft 30 for raising and lowering a screen, and a constant load unit 60 which outputs a constant load for application to the drive shaft 30, wherein the constant load unit 60 can switch between simple use in which the constant load unit 60 is used alone with respect to the drive shaft 30, and connected use in which the constant load unit 60, in a position flipped vertically with respect to simple use, connects to a gear unit 50, which changes the speed of rotation of the drive shaft 30, to transmit a constant load to the drive shaft 30.

Abstract: [Problem] To provide a shielding device provided with a speed adjustment unit which is capable of automatically adjusting the movement speed of a shielding material using a simple configuration, and with which noise during operation is suppressed. [Solution] According to the present invention, provided is a shielding device in which a shielding material is opened and closed by rotating a winding shaft. The shielding device is provided with a speed adjustment unit for automatically adjusting the movement speed of the shielding material. The speed adjustment unit is provided with: a housing for accommodating a viscous fluid; and a moving member which is accommodated inside the housing, and which moves in accordance with the rotation of the winding shaft. Furthermore, the speed adjustment unit is configured such that the resistance force that the moving member receives from the viscous fluid changes in accordance with the movement of the moving member.
