Abstract
A method and a pressing apparatus for pressing an armature shaft into an axial hole formed on an approximately cylindrical core, so as to protrude the shaft from the specified end face of the core at the specified protrusion dimension. A gage base is provided in which a shaft through hole of the same dimension as the specified protrusion dimension is formed. The core is placed on the gage base with the specified end face facing down. The shaft is first pressed into the axial hole to protrude it downward from a lower face of the shaft through hole. Next, the shaft is pushed back upward until a shaft push back portion reaches the gage base, thereby, protruding the shaft form the specified end face of the core at the specified protrusion dimension.
