PROBLEM TO BE SOLVED: To provide a connecting structure free from thermal stress, loosening/backlash, and the like generated on a connecting portion due to difference in thermal expansion coefficients.SOLUTION: In a connecting structure 10 for axially connecting a first shaft member 11 and a second shaft member 12, thermal expansion coefficients of the first shaft member 11 and the second shaft members 12 are different from each other, a hollow part of the first shaft member 11 and a projecting part of the second shaft member 12 are fitted to each other, a through hole penetrating through the hollow part of the first shaft member 11 and the projecting part of the second shaft member 12 fitted to each other, in the direction orthogonal to the axial direction, is formed, a shear pin 13 is fitted and inserted to the through hole, a conical face 11b is formed at an end face side of the hollow part of the first shaft member 11, a conical face 12b is disposed at a basic end side of the projecting part of the second shaft member 12, and the conical face 11b of the first shaft member 11 and the conical face 12b of the second shaft member 12 are kept into contact with each other. |
