PROBLEM TO BE SOLVED: To make blocks displaceable to any position while securing the degree of freedom in the configuration of blocks. SOLUTION: In a solid body composed of a plurality of blocks obtained by dividing a spherical body and connecting them together such that adjacent blocks are relatively displaceable from one another, all or part of adjacent blocks are connected with one another with joint members J, and the joint members has a protrusion or recess formed at two sides to be engaged with blocks to constitute the solid body composed of displaceable blocks. It is necessary to arrange the joint members at the connecting positions of blocks where the similarly protrusion or recess sides of them abut on each other when they are displaced, but other connecting parts may be connected to each other by way of joints.
