Abstract

PURPOSE:To prevent the strain at the time of press-fit and fixation of an armature core to a shaft by providing the inside diameter of the armature core with a press-fit fitting section and a gap fitting section having a recessed part of the inside diameter and making press-fit of the shaft into the inside diameter of the armature core. CONSTITUTION:A press-fit fitting section 2f is formed in the inside diameter of both ends of an armature core 2, and a gap fitting section 2g is formed on the central part. Press-fit and fixation of the armature core 2 to the shaft 1 is made at two places of the press-fit fitting section 2f. A bend of the shaft 1 due to a non-uniformity of the inside diameter of the armature core 2 is prevented by an existance of the gap fitting section 2g.
