PURPOSE:To suppress the increase of the weight accompanied with the installation of an elevation board and obtain the simple constitution and permit cost cut by constituting an elevation device so that a part of the load carrying platform of a vehicle to be used in common as the elevation board. CONSTITUTION:Onto a load carrying platform 2 of a ban type truck 1, an elevation board 4 is installed by using a part of a floor 3 in common, and said elevation board 4 can be slided to the rear part of the load carrying platform 2. Further, the elevation board 4 is formed from iron plates, etc., and the both side surfaces are fixed at the lower edge of a supporting body 5. The supporting body 5 is constituted of an upper rotary supporting body 30 and a slidable supporting body 31 inserted inside, and the elevation board 4 is moved in the longitudinal direction by swinging the turning-supporting body 30 around a supporting shaft 11 by a hydraulic cylinder as the driving body 6 in the longitudinal direction. Further, the slidable supporting body 31 can be extended and contracted for the rotary supporting body 30 by winding and rewinding a wire as an elevation operation body 7 by the drive of a driving body 12.
