Intake manifold

Abstract

An intake manifold includes a curved passage extending in a curved manner. The curved passage includes a first segmental body and a second segmental body that are separate from each other in a longitudinal direction of the curved passage and are welded together by a weld portion. The weld portion includes a main weld part and an auxiliary weld part. The main weld part annularly extends in a peripheral direction of the curved passage. The auxiliary weld part is arranged on an inner portion of the curved passage with respect to a curvature direction of the curved passage at a position separated from the main weld part in a radially outward direction of the curved passage.
