PURPOSE:To prevent eccentricity of a gear coupling owing to ununiformity in the top clearance and also prevent touch and collision of outer teeth with a stopper, by inhibiting radial displacement of the rotary shaft and sleeve and by putting them into good alignment by means of provision of a flexible member having damping effect for an axial displacement. CONSTITUTION:A flexible member 15 is provided so as to couple a tougue and groove part 13 formed at the end of a rotary shaft 1 with another tougue and groove part 14 formed at the inner circumferential surface of a sleeve 6. A member 15 is fitted so that the center of the rotary shaft 1 is put in alignment with the center of a floating part composed of a sleeve 6, spacer 8 and stopper 10, and the flexible member 15 shall be composed of a diaphragm. Accordingly, the top clearance delta at the meshing part of hub's outer teeth 5 of the hub with the inner teeth of the sleeve 6 will be uniform throughout the circumference. As the gap epsilon between the stopper 10 and outer teeth 5 is kept uniform with the aid of the spring force of the member 15, touch or collision of the stopper 10 with the outer teeth 5 is prevented. |
