A throttle body assembly, and method of manufacturing such, is disclosed having a unitary shaft and blade component injection molded in situ within a throttle body housing to mechanically entrap the shaft and blade component, yet still allowing for it to partially rotate, within the throttle body housing. The throttle body housing defines an interior passage, a shaft through-hole, and a shaft socket opposite the shaft through-hole, both aligned along a transverse axis to the interior passage. The shaft and blade component is a single unitary piece injection molded in situ within the throttle body housing, such that it has a blade section disposed within the interior passage, first and second shaft sections extending from the blade section opposite each other partially disposed within the shaft socket and shaft through-hole, respectively, and a pivotable axis generally coaxial with the transverse axis. |
