Abstract
In a resin-made throttle body for controlling air flow rate in an air intake passage, orientation of resinous material of a wall of the throttle body surrounding the valve member has a step portion for controlling orientation of fiber-including resinous material. As a result, the inner periphery of the wall can expand or contract evenly as the valve member expands or contracts.
