<p>PURPOSE:To effectively make use of the inside of a container as a housing space. CONSTITUTION:Paired folding doors 12 and 12A are provided, which opens/ closes the opening section 11 of a container 10. A link arm 14 is crosslinked between the upper end of an upper side door 12 and the middle of the container 10. Rotating rollers 19 are rotatably carried by the lower end section of a lower side door. The rotating rollers 19 are guided by the recessed grooves 14A of the link arm 14. The upper side door 12 is connected to the container 10 by a gas spring 21. When the respective doors 12 and 12A are opened, the respective doors 12 and 12A are energized to the open direction by the gas spring 12. When the opening section 11 is closed, this constitution thereby eliminates a housing space for the gas spring 21 under the floor of the container 10.</p> |
