PROBLEM TO BE SOLVED: To provide a cradle which prevent as much as possible a hollow formed body from being raised without increasing the weight. SOLUTION: The cradle 10 includes: a receiving part 11 which is used for fixing the hollow formed body 2 onto a form 1 for a floor plate, extends from a bottom part 11a just below the hollow formed member 2 to both sides of the hollow formed member 2, and further extends to a front end 11b at the side of the hollow formed member 2; an engagement member 12 extending from the bottom part 11a downward; a fixing means 13 for fixing the lower part of the engagement member 12 to the form 1 for floor plate; and a pressing member 14 which connects both ends 11b, 11b and is allowed to come into contact with the upper surface of the hollow formed member 2. A reinforcing member 15 is installed between the engagement member 12 and the receiving part 11. The reinforcing member 15 has a function of suppressing the deformation of the receiving part 11 when the hollow formed member 2 starts to be raised in the direction apart from the form 1 by buoyancy.
