Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a screw type supercharger for preventing the degradation of compressing efficiency by suppressing a change of a gap between rotors during operation. SOLUTION: The screw type supercharger 1 is rotationally driven with the male rotor 2 an the female rotor 3 spirally formed gearing each other to compress air sucked from a suction port 11 between the male rotor 2 and the female rotor 3 and discharge it from a discharge port. It comprises bearing casing parts 12, 13 each having a portion fixing the bearing of the male rotor 2 formed integrally with a portion fixing the bearing of the female rotor 3. The bearing casing pats 12, 13 are formed of members having linear expansion coefficients lower than those of the male rotor 2 and the female rotor 3. COPYRIGHT: (C)2008,JPO&INPIT
