PROBLEM TO BE SOLVED: To provide a connecting structure of rotary shafts, capable of preventing a bending stress placed on one rotary shaft from being transmitted to the other rotary shaft without using a joint member. SOLUTION: In the connecting structure of rotary shafts, a D-shaped hole part 21 is provided in a main driving-side rotary shaft 2, a D-cut part 31 is provided in a driven-side rotary shaft 3, and the D-cut part 31 is inserted to the D-shaped hole part 21. An outer curved surface 33 of the D cut part 31 includes a mountain-like bump 5 projected so as to extend in a circumferential direction of the curved surface, and an outer flat surface 32 of the D-cut part 31 includes a mountain-like bump 4 projected at a position continued to the mountain-like projection 5 so as to cross the flat surface. The D-shaped hole part 21 and the D-cut part 31 are linearly contacted with each other through a D-shaped annular projection, so that the main driving-side rotary shaft 2 is rotatable relative to the driven-side rotary shaft 3.
