る。In conventional refrigerator doors, a flange is formed at the front opening of the outer box of the refrigerator, and a synthetic resin gasket mounting frame for mounting a gasket that closes the flange is folded around the peripheral edge of the door's thin steel plate outer panel. The method for fixing the gasket to the rear flange formed by bending is to form the gasket mounting frame into a frame shape made by bending an extrusion molded product, and attach this gasket mounting frame to the rear flange of the door outer panel using fastening parts such as screws. There is a way to fix it. In this method of fixing using fastening parts such as screws, if urethane is foamed on-site while the gasket mounting frame is fixed with metal materials such as screws, the gasket mounting frame will expand and crack due to the heat generated by the foaming. This also causes the screws to loosen over a long period of time, resulting in inconsistent quality.
本発明は上記欠陥を改良する為に成されたものである。The present invention has been made to improve the above defects.

とによって仮固定する。The double-ripened eggs 3 and 4 are assembled into a flat box-shaped door outer plate 6 made of a thin steel plate with an open back side and a synthetic resin door inner plate 7 that closes the open back side. 8 is a frame-shaped gasket I/M frame formed by bending an extruded synthetic resin body;
A mounting groove 8a into which the mounting portion 5a of the gasket 5 is mounted is continuously formed in a part. The door outer plate 6 has a peripheral edge bent to form a rear flange 6a, and a groove 6b with a narrow opening is continuously formed in the rear flange 6a. Next, the rear flange 6a of this door outer panel 6
A method for fixing the gasket mounting frame 8 will now be described. A gasket mounting frame 8 was attached so as to cover the groove 6b of the rear flange 6a of such a door outer panel 6, and the gasket mounting frame 8 was attached to the inside of the door outer panel 6 as shown in FIG. An inner jig 9 and an outer jig 10 that holds the entire gasket mounting frame 8
Temporarily fix it by
