<p><P>PROBLEM TO BE SOLVED: To provide a transmission having excellent power transmission efficiency even when a conical roller bearing is used in a supporting structure of a shaft. <P>SOLUTION: The transmission T includes an input shaft 1 to which an output torque of a power source E is input, a first output shaft 2 and a second output shaft 3 which are arranged in parallel with the input shaft 1 respectively and provided with drive gears 20, 21 constantly meshed with an output gear 22 rotating integrally with the output member D respectively, and a plurality of transmission mechanisms 10 to 18 which selectively transmit a torque between the input shaft 1 and each output shafts 2, 3, having different change gear ratios respectively. In the transmission T, the output torque is transmitted to the output member D via the input shaft 1 and either output shaft 2 (or 3) and drive gear 20 (or 21). Out of each output shaft 2, 3, the drive gear 20 is relatively rotatably and selectively provided to enable a torque transmission torque relative to the first output shaft 2 supported by the conical roller bearings 6, 7. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
