PURPOSE: An opening/closing device for a roll-type insect screen and a roll-type insect screen apparatus including the same are provided to allow the user to control the extension length of an insect screen by opening or closing windows because the insect screen is unrolled or rolled along with the windows. CONSTITUTION: An opening/closing device for a roll-type insect screen comprises first and second latches(10,20), a rotator(30), a first latch block(100), and a second latch block(200). The first and the second latch are separately placed with a variable gap, wherein each latch includes a locking protrusion protruding from a latch block case and a body elastically supported by a first or second spring(42,44). The rotator is turned to adjust the gap of the first and the second latch. The first latch block is formed on a side of a lead frame for drawing out an insect screen rolled in a roll-type insect screen device. The second latch block is attached to one end of a window frame and comprises a recess which is cross-coupled with the first and the second latch. |
