Claims

[Scope of utility model registration request]

A Roots pump consisting of a plurality of rotors is arranged in the intake system of an internal combustion engine, and power is transmitted between the rotors on the drive side and the rotor on the driven side by mutually meshing gear means on their respective rotating shafts, and the rotor on the drive side The rotary shaft of the rotor on the driven side is connected to the drive shaft of the internal combustion engine, and the rotary shaft of the driven side rotor is connected to the rotary drive shaft of an auxiliary machine of the internal combustion engine that can rotate without substantially rotational fluctuation,
A backlash prevention device for a Roots pump supercharger of an internal combustion engine, in which gear means on the driving side and driven side are kept meshing in one direction by the driving torque of an auxiliary machine.
