PROBLEM TO BE SOLVED: To provide an annular component fitting method and its device whereby an inner shell component can be fitted in place at a high rate of success at a lower heating temperature irrespective of whether or not roundness before heating is admissible and differences in material only if the localized thickness of an outer shell component is good by heating the outer shell component while correcting it. SOLUTION: This device has a mold 3 of good bore accuracy, for binding the outer peripheral surface of an annular outer shell component 1 made of magnetic substance, insertion/conveyance means 5A, 5B for inserting the outer shell component 1 into the mold 3, and an outer-shell-component-heating high frequency coil 4 provided in proximity to the radially inner part of the mold 3. When the outer shell component 1 is induction heated as it is bound at the bore of the mold 3, not only its outside diameter but also its inside diameter is corrected whereby an inner shell component can be fitted in place at a high rate of success.
