Abstract
A motor vehicle intake muffler duct is formed by integrally bonding an upper duct, a lower duct and a separator interposed between them. Three airways are formed between the upper duct and the separator, seven muffler chambers are formed between the lower duct and the separator, and the airways and the muffler chambers are communicated with each other through vent holes which are formed in the separator. An intake muffler duct in which multiple muffler chambers are integrated with the airways, can be formed from only three components, which are an upper duct, a lower duct and a separator, and moreover although it has a compact structure, it is possible to reduce the intake noise effectively.
