Abstract:
1. A resin intake manifold comprising: at least two separated bodies including a first body and a second body, wherein said first body has a first protrusion, and said second body has a second protrusion connected to said first protrusion in accordance with a vibration welding, wherein said first body has a first cover wall arranged in an inner side of said first protrusion with leaving a first space with said first protrusion, and a second cover wall arranged in an outer side of said first protrusion with leaving a second space with said first protrusion, wherein said second body has a first recess groove receiving said first cover wall in an inner side of said second protrusion, and a second recess groove receiving said second cover wall in an outer side of said second protrusion, wherein said first protrusion and said second protrusion are respectively extending in parallel to a vibrating direction of the vibration welding, wherein said first cover wall in the inner side of said first protrusion is longer than said first protrusion, in such a manner as to prevent a burr generated at a time of welding said first protrusion portion and second protrusion from extending beyond said first cover wall in the inner side of said first protrusion, wherein said first cover wall is longer than said second cover wall, and wherein a welding surface of said first protrusion is convex, and a welding surface of said second protrusion is concave, in a cross section orthogonal to an extending direction of said first protrusion and said second protrusion.
