PURPOSE:To aim at enhancing the transmissibility of power and the resistance force against axial thrust, making a shaft coupling rigid and making the shaft coupling short, by providing a spiral spring which circumscribes a spherical body, and as well by connecting both ends of the spring to shafts. CONSTITUTION:A spiral spring 2 is provided circumscribing a spherical body 2, and both ends of the spring 2 are connected to shafts 3. As a result the spherical body 2 serves as a guide member for restraining the spring from deforming due to a decrease in the diameter of the spring 2. |
