Claims

[Scope of utility model registration request]

In a speed limiting device for a vehicle, in which a rotary flow control valve is provided in an intake passage of an internal combustion engine mounted on a vehicle, the flow control valve is connected to a rotating shaft and a rotary type flow control valve that changes the passage area of the intake passage. It is composed of a valve body attached to a shaft and a lid rotatably supporting the rotation shaft, and the rotation shaft and the valve body are connected to the intake passage through an opening formed in a side wall of the intake passage. An intake ratio control device for an internal combustion engine, characterized in that the intake ratio control device is inserted into the interior of the engine, and the opening is closed by the lid.
