PROBLEM TO BE SOLVED: To provide a sealing structure between load receiving deck for load receiving deck and loading space opening part, capable of keeping a sealing function by adapting to a gap it even if the gap between side edges of the load receiving deck and a peripheral surface opening part of the loading space becomes large with a simple structure without high accuracy. SOLUTION: In this load receiving deck elevating apparatus constituted so that the load receiving deck 6 may be provided between the loading space 15 and the ground so as to elevate freely, and the load receiving deck 6 may be enclosed and disposed in a standing condition to cover the peripheral surface opening part of the loading space 15, a packing 7 is provided along the side edge in the side edge 15a of the peripheral surface opening part, a pressure contact member 8 which is brought into pressure contact with the packing 7 when the receiving deck is enclosed and disposed is provided at a side edge 6a of the receiving deck 6. A protrusion piece 82 which is brought into contact with an outer side part of the packing 7 when the receiving deck 6 is enclosed and disposed is provided at the pressure contact member 8. A cross sectional surface of a top end side protrusion part 72 for this packing 7 is formed in a roughly circular, on the other hand an inner side surface 83 of the protrusion piece 82 is formed in an inclination surface so as to become thicker from the top end to the base end.
