PROBLEM TO BE SOLVED: To provide a structural unit which can be easily assembled and disassembled without falling even if an animal comes into contact with the animal, and can be optimally arranged according to the habit of the animal. SOLUTION: A structural unit 1 according to the present invention is used for an animal guidance device for guiding a wild animal to a predetermined place, and three support pillar members 2 are erected on the ground at intervals. A triangular bottom surface region D formed by connecting the lower end portions 2a of the three strut members 2 and a strut connecting member 3 including three strut connecting members 3 for connecting the two adjacent strut members 2 to each other. A space Q is formed by connecting the upper end portion 2b and the lower end portion 2a of the two strut members 2 connected by 3 and the side surface region S having one side of the bottom surface region D as the base. It is a feature.
