PROBLEM TO BE SOLVED: To provide a floor member for a slope with increased strength in a longitudinal (extending) direction of the slope. SOLUTION: Aluminum extruded material of which the cross section can be fitted is used, and the floor member jointed by fitting is made in one piece of panel, providing large rigidity to bent stress in an arranged direction, and reducing the thickness of the cross section and height of the floor member. With this structure, a lightweight rail with a running off prevention function of a wheelchair is sufficient, replacing a "thick" reinforcement rail located at both ends at the width of the slope. Therefore, it is possible to reduce weight of the slope device, and cost accordingly. COPYRIGHT: (C)2009,JPO&INPIT
