A plurality of sheet members are arranged on the circumferential surface forming a space, and edges of the sheet members adjacent to each other are arranged to overlap each other. Moreover, a first joint part and a second joint part to combine the sheet members are formed at regular intervals in a part where the sheet members are overlapped, and a test space is formed between the first joint part and the second joint part. A nozzle to inject air to the test space can be installed in the sheet member.</p> |
