PROBLEM TO BE SOLVED: To reduce weight and costs by suppressing damage caused by heat without providing a large-size cooler when exhaust gas is introduced to a resin intake manifold and without forming the intake manifold by a special highly heat-resistant resin material. SOLUTION: A manifold body is formed with a slot 26 for inserting an exhaust gas introducing member 3. The gas introducing member 3 is formed of material having higher heat-resistance than resin material composing the manifold body. The gas introducing member 3 has an exhaust gas circulating tube 50 for introducing exhaust gas therein, exhaust gas nozzles 50a opened in the outer surface of the exhaust gas circulating tube 50, and a cylindrical member 52 arranged to surround the outer surface of the exhaust gas circulating tube 50 and to be opposed to the exhaust gas nozzles 50a. The cylindrical member 52 is arranged to be placed in an intake passage. COPYRIGHT: (C)2010,JPO&INPIT |
