PROBLEM TO BE SOLVED: To provide a loading platform elevating device which surely prevents the jumping up of a loading platform during traveling from occurring. SOLUTION: The downward movement of the distal end section 132a of the loading platform 130 at a housing position is regulated by a guide roller 142 which is attached to a movable side supporting member 110 through a roller attaching plate 141. Also, the roller 145 of a regulating arm 143 which is turnably attached to the roller attaching plate 141 is depressed by engaging it with a pressing member 104 which is attached to a sliding rail 101 at the housing position, and the distal end section 132a of the loading platform 130 is pinched by the roller 145 and the guide roller 142. In this manner, the distal end section 132a is motion-regulated from the top and the bottom, and the jumping up of the loading platform 130 can surely be prevented from occurring.
