のスロツトル装置。 Intake passages are arranged in parallel in the throttle body, and a throttle valve is interposed in each intake passage, and these throttle valves are attached to a single valve shaft that passes through the throttle body, and each end of the valve shaft is connected to the throttle body via a bearing. In a throttle device for an internal combustion engine, the valve shaft is freely supported for rotation and is inserted between the two throttle valves into a hollow hole of the throttle body through a predetermined gap between the inner wall of the hollow hole and the inner wall of the hollow hole. An internal combustion engine characterized in that the downstream side of the intake passage of the valve stem is removed so that a predetermined gap between the outer wall of the valve stem and the inner wall of the hollow hole is larger on the downstream side of the intake passage than on the upstream side of the intake passage. Throttle device.
