摘要： An apparatus for preventing flow noise which suppresses the noise caused at the time of opening of a throttle valve provided in an intake passage of an internal combustion engine etc. At the downstream side of a pair of clearances formed at the top and bottom when the throttle valve opens, a means is provided acting on the flows of air passing through at least one of the clearances to reduce the flow rate and acting on the flows to cause the point of convergence of the flows of air passing through the pair of clearances to shift to the downstream side.
