PROBLEM TO BE SOLVED: To prevent a rear end rail for supporting lighting devices fixed to a retractable frame from being plastically deformed in a container trailer provided with the retractable frame. SOLUTION: Portions 78b in the range near ends of the rear end rail 78 for supporting the lighting devices have portions 78a near the center through elastic plates 79. When the rear end rail 78 receives an external force, the elastic plates 79 are deformed and the portions 78b near to ends of the rear end rail 78 for supporting the lamp units 77 swing with respect to the portion 78a near the center, thereby absorbing the external force. After the external forces against the rear end rail 78 are removed, the elastic plates 79 are recovered in forms before being deformed and the portions 78b near the ends of the rear end rail 78 for supporting the lighting devices 77 are laterally placed in alignment with the portion 78a near the center of the rear end rail 78.
