Abstract
A keep-back recess for blocking water, which is likely to be transmitted to a throttle valve along an inner peripheral surface of an intake pipe, is formed at an inner surface of a throttle body. The keep-back recess collects and stores water so that the throttle valve is prevented from freezing without leading engine cooling water in the throttle body.
