ABSTRACT:
A tension adjusting apparatus comprising a coupling device for movably coupling both ends of an elongated member disposed in the shape of a loop in a direction in which both ends approach and/or move apart from each other along the longitudinal direction of the elongated member, and an urging member retained by the coupling device and for urging the elongated member via the coupling device in a direction in which both ends of the elongated member approach to each other in order to apply tension to the elongated member. The smooth movement of the elongated member transmitting motive power and the tension of the elongated member at a predetermined value are thereby maintained without impeding the durability of the elongated member.
