Abstract
A disk-shaped throttle valve composed of an injection-molded resin having first main surface and a second main surface which are generally parallel includes a circular groove or semi-circular grooves centered on a gate resin portion where the resin is injected. The first main surface may also include a recess portion around the gate resin portion positioned such that the gate resin portion does not project beyond the first main surface. An accumulated resin portion may also be disposed on the second main surface opposite the gate resin portion, the accumulated resin portion being formed as a protrusion positioned such that an apex portion does not project beyond the second main surface.
