ABSTRACT:
In a transmission gear for transmitting two rotary motions from a driving mechanism to a working mechanism, the transmission gear comprises a cylindrical support member, a flexible cylindrical member fixedly supported by the cylindrical support member, first and second input shaft members, and first and second output shaft members. The first and second input shaft members have non-circular peripheral portions, respectively. The first and second output shaft members have internal circular portions radially opposite to and spaced apart from the non-circular peripheral portions of the first and second input shaft members, respectively. The flexible cylindrical member interposes between the non-circular peripheral portions of the first and second input shaft members and the internal circular portions of the first and second output shaft members. The flexible cylindrical member further having a buffer portion between the first and second transformable intervening portions for allowing the first and second transformable intervening portions to transform independently of each other without interference, thereby transmitting the rotary motions from the first and second input shaft members to the first and second output shaft members, respectively, in independent relationship to each other.
