PURPOSE: An insect screen device is provided to maintain the state of a frame by preventing a winding post in which an insect screen is wound from being separated from the frame. CONSTITUTION: An insect screen device comprises a frame, a movable post(20), an insect screen(40), a winding post(50), a moving member, and a protrusion member(23b). The movable post is movable along the frame. One side of the insect screen is coupled to the movable post, and the other side is coupled to one side of the frame. The winding post is movably installed between the movable post and one side of the frame and winds the insect screen. The moving member is installed on the top of the winding post and movably supports the winding post. The protrusion member controls the rotation of the winding post to prevent the insect screen from being unwound from the winding post. |
