PROBLEM TO BE SOLVED: To provide a tool for correcting dimensions, which exhibits heat resistance, excellent dimension accuracy and durability even at a very high temperature and with which an increase in the production cost can be prevented. SOLUTION: The tool for correcting the dimensions has an inner frame member 22 having an inverted truncated cone form and an outer frame member 23 which has been obtained by dividing a circular body having an inner hole nearly corresponding to the inverted truncated cone form of the inner frame member 22. The inner frame member 22 having the inverted truncated cone form is pressed and fit into the inner hole 23a of the outer frame member 23 so that the outer frame member 23 is push-expanded to a prescribed position and the inner frame member 22 is fixed in the outer frame member 23. At this time, the inner frame member 22 and/or the outer frame member 23 are made of a C/C composite material being impregnated with silicon. |
