PURPOSE:To make it possible to ensure an opening-closing operation even when the structure of a hinge part of an opening-closing panel is formed of elastic bodies of synthetic resin. CONSTITUTION:An arm rod 3 made of synthetic resin is extended from an opening-closing panel 2 of a frame body 1 and a hinge 4 is provided in the end part of the arm rod 3, while an engagement projection 5 is provided on the lateral side of the arm rod 3. On the other hand, a fitting arm 8 made of synthetic resin which is fixed to the frame body 1 by using a fixing piece 9 is provided and a bearing 6 forming the hinge 4 together with the arm rod 3 is provided in the end part of the fitting arm 8. Moreover, a projecting part 7 engaging with the engagement projection 5 is provided in the vicinity of the fixing piece 9 of the fitting arm 8. Besides, a folded-back part 10 is provided in the vicinity of the bearing 6 of the fitting arm 8. By positioning the end part of the arm rod 3 having the hinge 4, between the fitting arm 8 and the folded-back part 10, the arm rod 3 and the fitting arm 8 are displaced together and the engagement of the engagement projection 5 with the projecting part 7 is ensured. |
