PURPOSE: A motor manufacturing method is provided to prevent the shaft of a motor from being inclined by securely forming a housing which supports a rotor. CONSTITUTION: A rotor(1) comprises a shaft(2). A base(10) comprises a housing hole. The base comprises a housing support part projected along the circumference of the housing hole. A housing(20) is inserted into the housing hole. The housing is supported by the housing support part. A penetration hole in which the shaft is inserted to one side is formed in the housing. A rotor supporter(30) is inserted into the other side of the penetration hole. A support groove supporting the shaft is formed in the rotor supporter. The housing and the housing support part have a fit tolerance. The housing is combined with the base.
