PROBLEM TO BE SOLVED: To provide an insert member which can maintain rigid fixed states of both members even if the insert member is placed in a high-temperature atmosphere, related to the insert member in which different kinds of the members which are different in thermal expansion coefficients are assembled to each other in a normal temperature atmosphere.SOLUTION: An insert member 10 comprises a first member 1 which is relatively small in a thermal expansion coefficient, and has recess 11, and a second member 2 which is relatively large in a thermal expansion coefficient, and has a protrusion 21. The protrusion 21 is pressure-inserted into the recess 11. When a shape, a size and a position of the protrusion 21 with respect to a shape and a size of the recess 11 at a normal temperature are regulated as relative physical amounts of the protrusion at a normal temperature, and a shape, a size and a position of the protrusion 21 with respect to a shape and a size of the recess 11 at a high temperature to which the insert member 10 is exposed are regulated as relative physical amounts of the protrusion at a high temperature, the recess 11 is composed of continuation including the relative physical amounts of the protrusion at the normal temperature, and the relative physical amounts of the protrusion at the high temperature.SELECTED DRAWING: Figure 4 |
