<p>PROBLEM TO BE SOLVED: To improve visual confirmation property at night when a platform is arranged on the ground by providing an illumination lamp which shines on the platform on a support frame which can travel up to the ground outside of a vehicle or a descent position arranged in the vicinity of it. SOLUTION: When a door is opened to get on and off an automobile by a wheeled chair, an illumination lamp 11 is lit automatically due to the change- over of a door switch which is interlcoked with the door. When a lift device 5 is operated to move a support frame 1 between a storage position in the automobile and a descent position outside of the automobile, the illumination lamp 11 moves together with the support frame 1 so that a platform 2 supported by the support frame 1 is illuminated at all times. Furthermore, a piston rod of a hydraulic cylinder as the lift device is connected with a basic end part of an upper arm 5a of two arms 5a, 5b which constitute a lift arm 5, and the lift arm 5 is turned vertically due to the expansion and shrinkage of the hydraulic cylinder to move the support frame 1.</p> |
