Press-fitting method and production method for press-fit product

A production method for producing a press-fit product in which a press-fitting component is fitted with a press-fitting target component, comprising:

• preparing the press-fitting component and the press-fitting target component;
• and
• press-fitting one of the press-fitting component and the 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;
• and
• the press-fitting the one of the press-fitting component and the press-fitting target component comprises:
• 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 that is set 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.
