Abstract
It is an object of this invention to provide a cylindrical body manufacturing method capable of setting a high coaxiality and a high run-out accuracy between a cylindrical member and a flange member. To achieve this object, in a cylindrical body manufacturing method according to this invention, the diameter of an end portion of a sleeve is increased by heating the end portion. A flange held at the end of a robot hand is clearance-fitted in an inner-diameter processed hole in the end portion of the sleeve while the central axis of the flange is aligned with that of the sleeve. The flange is then pushed to make the outer periphery of the flange abut against the end face of the sleeve.
