Abstract
An arm (3) supporting a tension pulley (2) around which an endless torque transmitting member (B) is looped is supported by a fixed member (E) via a base member (7). A torsion coil spring (8) is interposed between the base member (7) and the arm (3). The base member (7) is brought into pressure-contact with the fixed member (E) by a tightening force of a bolt (6). A pivot shaft (5) is fitted onto the outer circumference of the bolt (6) so as not to cause a tip to contact the fixed member (E). By transmitting an axial force generated by tightening the bolt (6) to the base member (7) via a flange (5A) formed on the outer circumference of the pivot shaft (5), the distribution of a contact pressure between the fixed member (E) and the base member (7) is optimized.
