To develop a method for installing an end member to a hollow shaft member for an office equipment in which a high degree of coaxiality and a high degree of vertical state can be attained, its manufacturing stages are simple and they can be realized under a less-expensive cost. The present invention is constituted by the steps comprising (1) using a hollow shaft member made of soft metal; (2) inserting the end member made of hard metal formed with a fitting groove satisfying some requirements into the hollow shaft; (3) forming round holes at the central part of each of the split dies and preparing a molding machine having more than three pressing members toward the center of each of the round holes; and (4) installing the end member to the shaft member with the pressing force of the pressing member.</PTEXT>
