PURPOSE: To improve airtightness by constituting a hinge mechanism for connecting a door to a panel body using a door side hinge member, a panel body side hinge member where a body part is connected to the door side hinge member through a coupling shaft, and the reverse-side leaf spring. CONSTITUTION: A mounting part 11a with a hole 11e is mounted to a support part 6 in a panel body 1 in a panel body side hinge member 11 and at the same time a body part 11c is connected to the mounting part 11a via a hinge part 11b. The body part 11c is formed in U shape and projects from an open edge 1a of the panel body 1, a cylindrical part 11d is provided at the tip, and the body part 11c is connected through a door side hinge member 5 and a coupling shaft 8a of a cylindrical material part 11d, thus connecting a door 3 to the panel body 1 so that it can be opened and closed freely. A leaf spring member 12 is provided with a hole 12a, is inserted to the holes 11e and 12a on the back side of the hinge member 11, and is clamped to a support member 6. By closing the door 3 and rotating latches 10 and 14 with a grip 9, a packing 2 is storngly pressed by the hinge mechanism 13 and the door 3, thus increasing airtightness. |
