The first covering portion covers at least a part of a vertebral arch of a vertebra at a head-side among the adjacent vertebrae, and thus can be fixed to the vertebra. The second covering portion covers at least a part of a vertebral arch of a vertebra at a buttock side among the adjacent vertebrae, and thus can be fixed to the vertebra. The joint portion couples the first covering portion and the second covering portion together while allowing changing relative positions of the first covering portion and the second covering portion.
