Further, when the coiled object 6 is removed, it returns to its original shape due to elastic deformation, which is also preferable in that it can withstand repeated use. On the other hand, if a material having a high elastic modulus is simply used for the outer shell block 58, the outer shell block 58 repels the deformation of the coiled object 6 due to the load and immediately tries to return to the original shape. Therefore, if the contact position shifts even slightly due to vibration during transportation, the outer shell block 58 may immediately repel and stable support may be difficult. Especially in marine transportation, the hull sway of the transport ship due to waves causes rolling and pitching of a magnitude that does not occur during land transportation, which makes stable support even more difficult.
