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.

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 comprising:
- 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,
- wherein the method comprises arranging the pillar shaped ceramic body inside the metal pipe while gripping the pillar shaped ceramic body using a chuck mechanism, the chuck mechanism comprising:
- gripping portions capable of gripping at least a part of the inner peripheral surface of the pillar shaped ceramic body;
- and protruded portions each having a surface capable of being in contact with at least a part of the first end face of the pillar shaped ceramic body.
