PURPOSE:To make a transmission device compact in size and optimum for carrying and pousing and to enable its rotational motion given to a base transmission lever to be transmitted to a transmission lever tip part so surely and smoothly by constituting it with each combination of base and bush type transmission lever, transmission lever tip part and bush type transmission lever, and outer transmission auxiliary sleeve and chuck. CONSTITUTION:This expansive rotational motion transmission device is provided with a sectional noncircular rotation transmitting base transfer material 1, where a rotation driving apparatus is attached, one or several pieces of section noncircular movable bush type transmission levers 3 being fitted in this base transmission lever 1, and a transmission lever tip part 113 installed in a tip end of this bush type transmission lever 3. In this constitution, a section ring- form bush type transmission auxiliary sleeve 4 is fitted in the bush type transmission lever 3, while an inner flange piece 114 to be engaged with the base transmission lever 1 is installed in a section ring-form outer transmission auxiliary sleeve 8, and this outer transmission auxiliary sleeve 8 and the bush type transmission auxiliary sleeve 4 are clamped together with a section ring-form chuck 12. |
