Claims

[Scope of utility model registration request]

In the engine intake control device, a valve shaft perpendicular to the intake passage is rotatably supported on a support having an intake passage, and a butterfly valve for controlling the opening degree of the intake passage is fixed to the valve shaft. The length between both end edges of the butterfly valve along the valve shaft is determined by the length of the intake air along the valve shaft in a plane including the butterfly valve when fully closed, so as to form a gap between the edges and the inner surface of the intake passage when fully closed. An intake control device for an engine, characterized in that the distance is determined to be smaller than the distance between the inner surfaces of the passages.
