<P>PROBLEM TO BE SOLVED: To solve a problem that in the configuration in which a rail apparatus supports both right and left ends of a bottom portion of a container, the rail apparatus cannot restrict deformation of a container in a right and left direction, and thereby a side face of the container may deform. <P>SOLUTION: The container 206 has step parts 262 arranged at both ends of the bottom portion and held by a door frame 205, a narrow part arranged between step parts 262, and protrusion parts 265 arranged on both ends of the narrow part and protruding downward. Accordingly, the intensity of the container can be improved while upsizing the container 206 and enlarging capacity thereof. Furthermore, cold air circulation is not interfered, and appearance and designability are improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
