Abstract
A refrigeration device has a first door with an opening and a second door for closing the opening in the first door. A first hinge member has a first connection portion fixed on a main body of the refrigeration device and a first hinged portion connected to the first door. A second hinge member has a second connection portion fixed on the first door and a second hinged portion connected to the second door. The second hinge member includes a columnar portion that is hinged to the first hinged portion. One of the columnar portion and the first hinged portion has a first shaft hole, and the other one has a first hinge shaft that extends into the first shaft hole. The novel device prevents a door body of the refrigeration device from being damaged at a hinged position and the reliability of the refrigeration device is improved.
