The auto tensioner is configured such that one end of the coil spring is locked and fixed to the base, and the other end of the coil spring is locked to the tension arm so that the tension arm is biased to swing in a certain direction by the torsional restoring force of the coil spring. In the Yona, one end of the coil spring is attached to the base.
An autotensioner characterized in that an autotensioner is provided with a spring receiving part for receiving part or all of the inner circumferential part of the range up to a phase angle part of 80 degrees.
