1. A windable screen device which can be unlocked from an inner side and an outer side of the device, the windable screen device comprising (a) a first screen which can be opened and closed along a guide rail; (b) a first movable-frame member which can be operated to open or close the first screen; (c) a locking element attached to the first movable-frame member; and (d) a locking-frame member which engages with the locking element to secure the first movable-frame member when the first screen is pulled out, wherein (e) the locking element includes (i) interior and exterior handle units respectively attached to an inner side and an outer side of the first movable-frame member; (ii) a hooking component which is rotatably attached to an attachment plate of one of the interior and exterior handle units and is engageable with an engagement portion provided in the locking-frame member; (iii) a spring member which rotatably biases the hooking component in a locking direction; (iv) an operating component rotatably attached to an attachment plate of the other one of the interior and exterior handle units; and (v) a transmission pin which extends through the first movable-frame member in a slidable manner such that the transmission pin transmits a rotation, generated when the operating component is pressed, from the operating component to the hooking component so as to disengage the hooking component from the locking-frame member (f) the interior handle unit and the exterior handle unit are respectively attached to the inner and outer sides of the first movable-frame member by attachment plates which extend in the opening and closing direction of the first screen in a manner such that the interior handle unit and the exterior handle unit face each other; and (g) the transmission pin pierces the first movable-frame member at a right angle with the opening and closing direction of the first screen.
