Therefore, the conventional refrigerator requires the strength and component configuration of components capable of withstanding the load of the food stored in the upper case, resulting in a large number of components and high price.
In addition, the sliding operation of the upper case has to be performed while lifting the upper case and pushing in the upper case, resulting in poor operability.
In general, the main use is to use short-term foods in the upper case and long-term preservation foods in the lower case, and the upper case is used more frequently. When the door is pulled out, only the lower case is drawn forward and the upper case remains behind, so that the upper case is difficult to see and difficult to use.

  SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. In the drawer mechanism of the upper and lower two-stage case in the drawer door, the components in the drawer mechanism of the upper case are reduced and the price is reduced. The purpose is to improve the storage volume of the case and the operability of pulling out.

  The refrigerator according to the present invention includes a refrigerator main body, a main body, and an upper case and a lower case. The drawer-type drawer door portion is separated from the outside by a drawer door. A handle configured to fit into a recess provided inside the drawer door in a state where the door is closed, and a handle having an opening is provided.
