<p><P>PROBLEM TO BE SOLVED: To provide a shaft coupling device capable of changing a spring constant in the rotating direction, preventing the lowering of spring constants in the axial direction and a direction vertical to the shaft. <P>SOLUTION: In this shaft coupling device 10, a cushion member 30 is interposed between an inner member 20 and an outer member 11 coaxially arranged to each other, and power storage condition is generated by compressing the cushion member 30 to be deformed. The cushion member 30 is formed with recessed parts 34 in a contact surface with the outer member 11. The recessed part 34 is formed into a semi-spherical hole shape, and a plurality of the recessed parts 34 are evenly arranged on the whole of the contact surface of the cushion member 30 with the outer member 11. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
