Abstract
A manifold which is mounted either on the intake side or on the exhaust side of an internal combustion engine. A main body of a manifold is divided into an end manifold, at least one intermediate manifold and a base manifold. Branch pipes are formed by a bulging process to project upright branch pipes on a side of each manifold, and manifolds are connected on ends with gaskets interposed therebetween so that the bending moment caused by the expansion of metal members due to hot exhaust gases may be absorbed instead of being concentrated on the roots of the manifold to enhance the durability of the manifold.
