ABSTRACT:
A belt tensioner for use of a V-belt which is spanned between a driving member and a driven member. The belt tensioner has an adjust bolt to be rotated by a worker, a bracket which slidably supports a slider secured to the driven member. The adjust bolt comprises a head portion, a first shaft portion which has a threaded relation with a hole within the bracket, and a second shaft portion which has a thread relation with the slider. Further, a spring is provided between the head portion of the adjust bolt and the bracket to bias the adjust bolt in such a direction as the head portion of the adjust bolt is separate away from the bracket, thereby obtaining an optimum belt tension force.
