PROBLEM TO BE SOLVED: To tightly stretch a pollen screen together with an insect net to a well-known frame used for an insect screen door or an existing insect screen door. SOLUTION: An insect net screen 13 and a pollen screen 14 are installed and fixed with presser members 15 to a link groove 20 with its opening portion narrowed, which is formed with an inner peripheral plane 21, a groove bottom forming protrusion 22, a groove side wall 23, and an engaged projected edge 24 at the tip end portion of a groove side wall 23. For fixing the insect net screen 13 and the pollen screen 14, a cover plate 31 covering the link groove 20; a contact portion 32 maintaining an inserted attitude by contacting to the inner peripheral plane 21 of the frame; and the cover plate or contact portion are all arranged as one body and fitted in a pressured state while elastically deforming by pressure welding to the engaged projected edge 24 of the groove side wall. And the insect net screen and the pollen screen are pinched between the groove side wall 23 and an inner side surface of the engaged projected edge 24, and they are all secured by an engaging projection 34.
