An AI pipe (1) is formed with a first housing (11) and a second housing (21). The first housing (11) is made from a thin metal sheet and has a clamp portion (C1) that was left remaining. The second housing (21) is also made of a thin metal sheet and also has a clamp portion (C2) that was left remaining. When fitted together, the first housing (11) and the second housing (21) form a pipe portion (31). With this AI pipe (1), a through-hole (H) which is punched out by press working is formed in at least one of the clamping portion (C1) and the clamping portion (C2). |
