PROBLEM TO BE SOLVED: To provide a storage such as a prefabricated storage for unpolished rice, for instance, which can alleviate a load on a hinge of an openable door, can adequately cope with the case where the size or weight of the door is enlarged and the case where opening frequency of the door is increased, without increasing the number of hinges to be attached thereto or without increasing installation strength of the same, thereby effectively preventing partial sinking, and can lead and hold the door to a normal position when it is closed even if slight partial sinking occurs, thereby achieving smooth opening/closing of the door at any time. SOLUTION: According to the storage 1, a front opening of a storage main body 2 is covered with an external openable door 3 which has a portion on which the hinge 4 is installed. Then, a roller 11 for preventing door partial sinking is installed on a lower end closer to a free end on the side opposite to the installation portion of the hinge 4, in a manner internally protruding therefrom. The roller 11 is received by a roller seat 30 which is formed on a bottom wall 2a of the storage main body 2 or at a location corresponding to the bottom wall 2a.
