Further, since the upper surface of the second support base 18 is provided with a rotation prevention hole 18b for receiving the base 24 provided at the lower end portion of the support main body 15 and preventing the support main body 15 from rotating, Inadvertent rotation can be prevented, and the liftable deck L can be prevented from falling off from the protrusions 11-14.
Furthermore, since the rising distance of the protrusions 11 to 14 when the height of the liftable deck L is changed is suppressed to the height of the S2 + (plus) claw portion 28b, the liftable deck L at the uppermost stage is released. Space, that is, the distance between the hull structure ceiling surface and the upper surface of the liftable deck L can be minimized, and the height of the entire hull structure can be reduced.
Furthermore, since the spring 23 is provided between the lower surface of the flange 20b and the upper surface of the third support 19, when the weight of the liftable deck L is not applied to the protrusions 11 to 14, The column main body 15 is lifted until the upper surface of the column main body 15 and the lower surface of the first support base 17 come into contact with each other by the urging force of the spring 23, and the operator simply turns the handle 22 to rotate the column main body 15. It can be rotated, so that the working efficiency can be improved and the working time can be shortened.
Furthermore, since the direction indicating needle 20a indicating the direction of the protrusions 11 to 14 is provided, the operator can identify the height of the protrusions 11 to 14 according to the direction of the direction indicating needle 20a, thereby improving work efficiency. As a result, the working time can be shortened.
Furthermore, since the bifurcated arm 28 of the liftable deck L is guided (guided) to the outer surface 15a of the column main body 15, work safety can be improved.

On the other hand, in a ship equipped with the liftable deck support 10 that can change the height of the liftable deck L in small increments, the dead space can be reduced and the vehicle can be efficiently loaded. In addition, the transportation cost can be reduced.
Moreover, since the space for escaping the liftable deck L in the uppermost stage can be minimized, the height of the entire hull structure can be reduced, and the wind pressure resistance of the hull can be reduced.
Furthermore, since the spring 23 is provided between the lower surface of the flange 20b and the upper surface of the third support base 19, and the direction indicating needle 20a indicating the direction of the protrusions 11 to 14 is provided, the column main body 15 is provided. Can be rotated easily, and the height of the protrusion can be recognized instantly, so that work efficiency can be improved, work time can be shortened and cargo handling time can be shortened. can do.
