PROBLEM TO BE SOLVED: To provide a driving force transmission system that enables two output shafts to be alternately and independently driven in a normally/reversely rotatable manner by one motor.SOLUTION: A driving force transmission system, which can rotatively drive a plurality of output shafts by a driving force of one motor, includes: a first output shaft 2 that is normally/reversely rotated on the basis of a motor operation; second and third output shafts 3 and 4 that can be normally/reversely rotated on the basis of normal/reverse rotation of the first output shaft 2; and selection devices 11, 13, 14, 15 and 16 that transmit the normal/reverse rotation of the first output shaft 2 by selecting either of the second and third output shafts 3 and 4. |
