PURPOSE: To eliminate a water leak so as to enable a door to open/close smoothly and further quietly by connecting upper/lower panels by a mobile hinge of elastic rubber or the like, and holding longitudinal direction both side flange parts of a hinge member interposed by a fixed and retaining piece of a supporting tube, so as to bring an upper tubular part into contact with an internal surface of the hinge member. ;CONSTITUTION: A supporting tube 20 is fixed by bolts to longitudinal direction both ends of a lower flange part 17 b of a hinge member 17 and to a lower side panel 12 by the bolts 19 through the suspension fixed piece. In a tubular part 20a in an upper part of this panel, a fixed piece in the lower part and a press piece 20c in the intermediate part are integrally formed, and both side lower flange parts of the hinge member 17 are pressed by the panel 12. The tubular part 20a is positioned in the intermediate between upper/lower panels, to insert a guiding roller shaft fitted. In the supporting tube 20, since its tubular part 20a comes into contact with an internal surface just in the intermediate position of a mobile hinge 13 when opened/closed a door, the supporting tube is regulated so that the mobile hinge 13 can be freely flexed, to prevent abnormally protruding the panel 12 in the upper part when flexed.;COPYRIGHT: (C)1996,JPO
