PROBLEM TO BE SOLVED: To provide a connecting structure for a rotary shaft whereby the workability of assembly and manufacture is improved, and from the halfway of shrinkage, a contraction load can be decreased. SOLUTION: In a connecting structure for a rotary shaft provided with an elastic unit interposed in a fitting part between external/internal mounting shafts 11, 12 to bring in a compressive condition partly a shaft part 12a of the internal mounting shaft 12 into press contact with partly a hole part 11b of non-circular section of the external mounting shaft 11; as the elastic unit, an elastic unit (leaf spring) 13 is adopted, which has a fitting part 13c fitted to a tip end of the shaft part 12a of the internal mounting shaft 12, and when the shaft part 12a of the internal mounting shaft 12 is fitted to be contracted in hole parts 11a, 11b of the external mounting shaft 11, it is moved integrally with the shaft 12a of the internal mounting shaft 12, and when fitted to the hole part 11a of almost circular section of the external mounting shaft 11, it is placed in from a compressed condition to a free condition. |
