チヤージヤー用ルーツポンプ。 In a supercharger Roots pump that supercharges intake air by rotating a pair of rotors that are arranged oppositely in a housing, one end of a shaft that pivotally attaches the rotor to the housing is locked from axial movement, and the rotor is pivoted to the housing. At the same time, the other end of the shaft is pivotally supported by the housing so as to be movable in the axial direction, and the side clearance between the side surface of the rotor located on the other end of the shaft and the inner wall surface of the housing is adjusted to the one end of the shaft. Roots pump for super chargers, which is characterized by having a larger side clearance than the .
