To prevent a tubular member from being damaged or an automatic hoisting tool from being broken, or a wire from being cut when the tubular member is to be hoisted and carried, and to prevent generation of deformation of a fixed frame, breakage of a foundation bolt, and abnormal wear of an inner wall surface of a stay.

In a cradle device 1 having stays 3 facing each other on both sides of a receiving base 2 for collecting a plurality of tubular member (e), the stay 3 comprises a stay body 3a and slide members 4 slidably fitted to the stay body 3a in the vertical direction on the inner side of the stay body 3a, and the slide members 4 have a surface on the side separate from the stay body 3a forming a surface along the substantially perpendicular direction, and are separated outwardly from each other when moving upwardly.
