<p>PROBLEM TO BE SOLVED: To provide a transmission capable of reducing an apparatus.SOLUTION: A transmission 1 comprises: an input shaft 2, to which a rotational power is inputted; a first output shaft 3 and a second output shaft 4 capable of outputting the rotational power inputted to the input shaft 2; a first transmission gear pair group 5 capable of changing the rotation number of the rotational power from the input shaft 2 and transmitting the changed rotation number to the first output shaft 3; and a second transmission gear pair group 6 capable of changing the rotation number of the rotational power from the input shaft 2 and transmitting the changed rotation number to the second output shaft 4. The first transmission gear pair group 5 is constituted to include an idle gear 7 capable of changing the rotation number of the rotational power from the input shaft 2 into two steps, and is supported rotatably relative to the first output shaft 3. The second transmission gear pair group 6 can change the rotation number of the rotational power from the input shaft 2 into two stages, and can change the rotation number of the rotational power transmitted from the input shaft 2 through the idle gear 7, into two stages. Therefore, the transmission 1 can shorten the axial length so that the system can be small-sized.</p> |
