A wheeled-chair chassis with a suspension mechanism which comprises a chassis structure, a suspension system, a transmission system and two front and rear wheels; the chassis structure includes a steel pipe frame similar to an inverse triangular frame. The suspension system includes shock absorbers, rocker arms, and pivot pins; one end of the rocker arm is connected with a pivot base on lower end of the steel pipe frame by means of a pin, while the other end thereof is mounted with a gear rack for mounting a motor of the transmission system, a gear box, and the rear wheels. The shock absorber is fixedly mounted between the steel pipe frame and the rocker arm to provide a retractable movement for absorbing a shake from the rear wheels and the rocker arm caused by a rough road surface in order to provide the chair with a comfortable driving. Since each of the systems is an independent assembly, it is easy to assemble.

A foldable container, of which each of the two side walls has two sections to be foldable inwards so as to have the side walls folded on the floor of the container; the roof of the container is then fallen upon the side walls. Between the roof and the folded side walls, there is a space to accommodate the two end walls; consequently, the container can closely be folded up to facilitate an empty container to be handled in freight. The present invention discloses the fastenable hinges of the side walls and the connecting device of the end walls.
