Abstract
A resonator type silencer connected to an air intake duct of an automotive internal combustion engine. The resonator type silencer comprises a first case having an open end section. A second case is fabricated separate from the first case. The second case has an open end section which is joinable with the open end section of the first case. The open end section of the first case includes an end edge portion having a linear projection extending along the end edge portion. The linear projection has an inclined face extending along the end edge portion and sloped down in a direction toward a surface of the open end section. The open end section of the second case includes an end wall portion. A guide wall is integral with the end wall portion and extending along an end edge portion of the open end section to define a groove extending along the end edge portion. A seal edge portion is formed at a surface of the guide wall and extends along the end edge portion of the open end section of the second case so as to define a part of the groove. The seal edge portion is contactable with the inclined face of the linear projection of the end edge portion of the first case. Additionally, an engagement mechanism is further provided in the resonator type silencer and includes a projecting section formed integral with one of the first and second cases. A receiving section is provided for receiving the projecting section so that the projecting section and the receiving section are engageable with each other, the receiving section being formed integral with the other of the first and second cases.
