PURPOSE: An air supercharger for an automobile is provided to supply outside air into a cylinder combustion chamber in complete turbulence state, and to increase supplied amount of the outside air while preventing damage of components thereof due to heat of an engine. CONSTITUTION: A rotary shaft(81) is forcibly inserted to a shaft insertion hole(80) of a rotary fan(4). A metal cylindrical auxiliary mechanism(86) having an inflow guide blade integrally formed on outside of a bearing housing(85) having a bearing(82) fixed to a center thereof, and has a stepped protrusion(87) formed on outside thereof. An end of the rotary shaft is forcibly inserted to the bearing forming the metal cylindrical auxiliary mechanism to allow the rotary fan to rotate. A preventing protrusion(91) is formed on an inside of a lower end of a metal fixed cylindrical mechanism having thickness identical with width the stepped protrusion of the cylindrical auxiliary mechanism to have identical width with thickness of an inflow housing(30). The inflow housing is forcibly inserted to the fixed cylindrical mechanism to be fixed by the preventing protrusion.
