1. A press-fitting method for press-fitting one of a press-fitting component and a press-fitting target component into or with the other by moving the one of the press-fitting component and the press-fitting target component in a press-fitting direction using a press-fitting tool, wherein:
the press-fitting tool comprises:
a pressing portion having a pressing surface configured to come into contact with the press-fitting component; and
a restriction portion having a restriction surface configured to come into contact with the press-fitting target component,
a press-fitting direction position of the pressing surface of the pressing portion and a press-fitting direction position of the restriction surface of the restriction portion are set so that the one of the press-fitting component and the press-fitting target component is stopped at a prescribed press-fitting stop position,
the press-fitting method comprising:
adjusting a press-fitting interval dimension in the press-fitting direction between the pressing surface of the pressing portion and the restriction surface of the restriction portion so as to obtain the press-fitting stop position of the press-fitting component that is set in the press-fitting target component according to component dimensions of the press-fitting component and component dimensions of the press-fitting target component;
press-fitting the press-fitting component with the press-fitting target component; and
stopping the press-fitting of the press-fitting component with the press-fitting target component by bringing the restriction portion into contact with the press-fitting target component.
