Abstract
An arm () supporting a tension pulley () around which an endless torque transmitting member (B) is looped is supported by a fixed member (E) via a base member (). A torsion coil spring () is interposed between the base member () and the arm (). The base member () is brought into pressure-contact with the fixed member (E) by a tightening force of a bolt (). A pivot shaft () is fitted onto the outer circumference of the bolt () so as not to cause a tip to contact the fixed member (E). By transmitting an axial force generated by tightening the bolt () to the base member () via a flange (A) formed on the outer circumference of the pivot shaft (), the distribution of a contact pressure between the fixed member (E) and the base member () is optimized.
