Claims

[Scope of utility model registration request]

The exhaust manifold is divided, an inner cylinder part is formed at the end of one exhaust manifold, and an outer cylinder part is formed at the end of the other exhaust manifold, so that the inner cylinder part can be freely moved in the axial direction into the outer cylinder part. In the seal structure of a split exhaust manifold in which a seal ring is fitted and provided between an inner cylinder part and an outer cylinder part, the seal ring is composed of a metal seal ring having a bellows part, and one end of the seal ring is fixed to one of the inner cylinder part and the outer cylinder part, and the bellows part is brought into contact with the other of the inner cylinder part and the outer cylinder part, and the exhaust gas force is applied to the bellows part in a direction that increases the contact force of the bellows part. The seal structure of the split exhaust manifold is characterized by applying exhaust gas pressure.
