Abstract:
A method for producing a shrink-fitted member by arranging a hollow type pillar shaped ceramic body inside a metal pipe and shrink-fitting them, the hollow type pillar shaped ceramic body including: an outer peripheral surface and an inner peripheral surface in a direction substantially parallel to an axial direction; and a first end face and a second end face in a direction substantially perpendicular to the axial direction. The method includes arranging the hollow type pillar shaped ceramic body inside the metal pipe while gripping the hollow type pillar shaped ceramic body using a chuck mechanism.
