<P>PROBLEM TO BE SOLVED: To provide a case body structure used for golf simulation or the like which can prevent removal of a golf ball, simplifies assembling work and disassembling work after assembling, reduces costs, and is easily transferred. Ž<P>SOLUTION: In the state that a front edge of a ceiling sheet body 6 is bent backward along a front surface and an upper surface of an upper horizontal stretched surface frame 11U, the front edge is tied by a rope 10 to an upper horizontal tying frame 12U. In the state that an upper edge of a screen 9 abuts on the outside of the ceiling sheet body 6 with respect to the upper horizontal stretched surface frame 11U, the upper edge is tied by the rope 10 to the upper horizontal tying frame 12U. In the state that front edges of right and left side face sheet bodies are bent backward along a front face, a left face, and a right face of right and left vertical stretched surface frames, the front edges are tied by the rope to the right and left tying frames. In the state that right and left edges of the screen 9 abut on the outside of the right and left side face sheet bodies with respect to the right and left vertical stretched surface frame, the edges are tied by the rope to the right and left vertical tying frames.
