Abstract
A plurality of transmission ports which are respectively closed by air-permeable members are disposed in at least two members selected from among the intake duct, the air cleaner, and the air cleaner hose in the intake apparatus. Amounts of air permeation of the air-permeable members are set so as to be mutually different in order to tune intake sound generated from the inlet port and transmitted sound generated from each of the air-permeable members. In addition, a cleaner-incorporated member may be accommodated in the air cleaner, the cleaner-incorporated member having one end communicating with one of the intake duct and the air cleaner hose in such a manner as to be separated from an interior of the air cleaner and another end which is open in the interior of the air cleaner. An outer wall of the air cleaner is formed by a dual-use outer wall portion which also serves as an outer wall of the cleaner-incorporated member as well as an exclusive-use outer wall portion for forming only the air cleaner. The outer wall of the air cleaner has at least one transmission port which is formed in such a manner as to extend over the dual-use outer wall portion and the exclusive-use outer wall portion, and which is closed by an air-permeable member.
