の溜り防止構造。 In a throttle body that is provided with a bypass passage that connects the upstream side and the downstream side of the throttle valve in the intake passage, and is equipped with a control valve that opens and closes the bypass passage depending on the engine ambient temperature, A return passage is provided that connects the downstream side and the upstream side of the throttle valve in the intake passage, and the position of the port on the intake passage side of the return passage creates negative pressure there when the throttle valve is idling or at a low opening. A structure for preventing accumulation of oil, etc. in a throttle body, characterized in that the throttle body is located at a position where negative pressure is generated when the throttle valve is opened at a medium opening or more.
