Abstract
A tensioner assembly includes a pulley arm pivotable about a pivot shaft, and a tension pulley mounted on the pulley arm at its end remote from the pivot shaft and pressed against a belt to keep the tension of the belt. The tension pulley is rotatably mounted around a base portion of the pulley arm through a rolling bearing with the inner surface and axial rear end surface of the bearing inner race in contact with the outer peripheral surface of the base portion and an end surface of a shoulder of the base portion, respectively. The base portion has an axial through hole formed with an internal thread on its inner surface. A support bolt is threaded into the through hole from the axial front end to press the rolling bearing against the end surface of the shoulder. The internal thread has an axial front end located in the vicinity of, or axially rearwardly of, the end surface of the shoulder.
