FIG. 1 is an explanatory diagram showing an example for determining the dimensions of the rotor and housing when the present invention is applied to the conventional roots-type supercharger shown in FIGS. 4 and 5. It is a diagram showing the ideal state of the locus drawn by the tip and the inner circumferential surface of the housing, and the solid line is the diagram at the time of manufacture (at room temperature) determined from the ideal state. FIG. 2 is a graph showing the relationship between the discharge temperature and the housing radii RhA, RhB and RhC of each part of the housing and the rotor radius Rr in the Roots type supercharger to which the present invention is applied. FIG. 3 is a graph showing the relationship between the discharge temperature and the housing radii RhA, RhB, and RhC of each part of the housing and the rotor radius Rr in another embodiment of the present invention. 4 and 5 are views showing an example of a conventional roots-type supercharger to which the present invention is applied, in which FIG. 4 is a sectional view in the axial direction, and FIG. 5 is a sectional view in the direction perpendicular thereto. be. FIG. 6 is a graph showing the relationship between the temperature of each part of the housing and the flow rate during operation of the Roots type supercharger. FIG. 7 is a graph showing the relationship between the discharge temperature and the housing radii RhA, RhB and RhC of each part of the housing and the rotor radius Rr in a conventional Roots type supercharger. FIG. 8 is a graph showing the clearance between the tip of the rotor blade and the inner circumferential surface of the housing for each part of the housing during operation of a conventional Roots type supercharger. 18: Housing, 24, 26: Blade, 28,

[Claims for Utility Model Registration] Roots-shaped rotors with multiple blades are rotated at the same speed in opposite directions within a housing, thereby sucking air through the intake port and supercharging the engine through the discharge port. A roots type supercharger, characterized in that the clearance between the blade tips of the rotor and the inner circumferential surface of the housing at room temperature is smaller in the vicinity of the discharge port than in the vicinity of the suction port.
