ABSTRACT:
A pivoting member for rotatably supporting a pulley contacting a belt is pivotally fitted with a fixing shaft via a bushing while a frictional member including a slidable surface being at a right angle to the axis of the fixing shaft is forced, by an elastic force of a resilient member, into contact with a frictional surface disposed either on the pivoting member side or the fixing side, whereby a pivotal resistance is imparted to the pivoting member. The resilient member is disposed at least one place on the circumference of a circle whose center is the fixing shaft so as to inhibit the pivoting member from being inclined by a load from the belt while the frictional member is locally disposed correspondingly to the resilient member.
