するルーツポンプ構造。 In a Roots pump that uses a mechanical supercharger for an internal combustion engine, the rotor placed inside the Roots pump housing is made of a material with a smaller coefficient of thermal expansion than the housing, and the rotor is placed in a recess at the tip of the long diameter of the rotor. A roots pump structure characterized in that a clearance correction member made of a material with a large coefficient of thermal expansion is fitted.
