US Patent 7341036 Intake device and mounting structure of valve unit

An intake device has an intake manifold, valve units each having a valve housing and a valve member, a shaft and deformed members. The intake manifold defines passages through which a fluid flows. Each of the valve units is disposed in a corresponding one of the passages of the intake manifold such that a passage of the valve unit is in communication with the passage of the intake manifold. The shaft passes through the intake manifold and the valve units, and rotatably supports the valve members. Further, each of the deformed members is disposed between the valve housing and the intake manifold and deformed therebetween.
