PROBLEM TO BE SOLVED: To provide a transmission gear set having two direction inputs and specified direction output.SOLUTION: When a rotating direction of an input shaft is changed to cause the input shaft to rotate in a different direction, an output of the same speed ratio or different speed ratio is attained. The transmission gear set having two direction inputs and specified direction output of this invention is constituted such that unidirectional transmission devices are mounted between a first driving rotational direction input gear set and an input shaft that can be rotated in a first driving rotational direction and a second driving rotational direction, and between the first driving rotational direction output gear set and an output shaft rotated in one-way, and the output shaft and the input shaft. The transmission devices are driven in the second driving rotational direction and at the same time the transmission devices in the first driving rotational direction are pulled out to avoid attenuation tracking. |
