Abstract
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).

-9. (canceled)
A vehicle component comprising:
- a part made of metal and having at least one clamping portion to be fixed to production equipment when the part is formed by press working in the production equipment,
- wherein at least one through-hole is formed in the at least one clamping portion so as to reduce the vibration noise generated by the part when mounted on an internal combustion engine.
(canceled)
A secondary air supply component of an internal combustion engine, comprising:
- a first part made of metal and having:
- a first wall section that forms a part of a secondary air passage, and that is formed by press working in production equipment;
- and
- a first clamping portion that is to be fixed to the production equipment when the first wall section is formed by the press working;
- and
- a second part made of metal and having:
- a second wall section that forms the other part of the secondary air passage, and that is formed by press working in production equipment to, and a second clamping portion that is to be fixed to the production equipment when the second wall section is formed by the press working,
- wherein the second wall section of the second part is fitted together with the first wall section of the first part to form the secondary air passage, and
- wherein at least one through-hole is formed in at least one of the first clamping portion and the second clamping portion so as to reduce the vibration noise generated by the component of the internal combustion engine.
