摘要：
A throttle valve of the invention includes a clearance closing member provided along a peripheral edge of a valve body displaceably and elastically deformable in a direction extending along an axis of an intake passage, a direction perpendicular to the axis of the intake passage, and a direction inclined with respect to the axis of the intake passage, for closing a clearance between the peripheral edge of the valve body and an inner wall surface of the intake passage.
