ABSTRACT:
An expandable chamber functioning as an expandable silencer, an air cleaner chamber functioning as an expandable silencer and a resonator chamber functioning as a resonant silencer are integrally formed in a main body of an intake silencer device. The air cleaner chamber and the resonator chamber communicate with each other through a communicating portion. A first intake duct is provided with one end extending into the expandable chamber and with the other end communicating with the atmosphere. A second intake duct is provided with one end extending into the expandable chamber opposed to one end of the first intake duct and with the other end extending into the air cleaner chamber. A third intake duct is provided with one end extending into the air cleaner chamber and connected to an air filter element. Thus, an intake silencer device has a high silencing effect, while being compact, and in which the rising of the temperature of an intake air and an increase in resistance to the flow of the intake air can be prevented.
