PROBLEM TO BE SOLVED: To easily install amusement facilities in a building at a low cost while easily renewing the required amusement facility at the low cost. SOLUTION: The containers 20 in which the amusement facilities are installed are set up in a building 1, and the amusement facilities are installed. Openings 2, to and from which the containers 20 go in and out, are formed in the building 1 while container supporting sections 3 for supporting the containers 20 in a freely going-in-out manner are fitted into the openings 2. Thus, the amusement facilities can be installed in the building by carrying in the containers on the container supporting sections 3 from the opening sections 2. The amusement facilities can be exchanged by replacing the containers in the building 1.
