Abstract
The present invention provides a driving force transmission device (P) which is adapted so that the distance (Ls) between the driving force transmission wheels such as a pair of pulleys (16,32) can readily and surely be changed, thereby, making it possible to constantly exert an appropriate tension on a driving force transmission member such as a belt (22), even without a tension roller. The driving force transmission device (P) includes: a first driving force transmission wheel (16) which is driven to rotate, a second driving force transmission wheel (32), an endless driving force transmission member (22) mounted around both the first driving force transmission wheel (16) and the second driving force transmission wheel (32) for transmitting driving force therebetween, and an eccentric shaft (40) which has a pivotal axis (O) at a position eccentric to an axis (Cb) of the second driving force transmission wheel (32) and on which the second driving force transmission wheel (32) is rotatably mounted. The driving force transmission device (P) is adapted so that the distance (Ls) between an axis (Ca) of the first driving force transmission wheel (16) and the axis (Cb) of the second driving force transmission wheel (32) can be changed by pivotally moving the eccentric shaft (40) about the pivotal axis (O).
