Abstract
An automatic tensioner for applying a tension to a belt of an engine for a vehicle comprises a shaft fixedly mounted on a part of the vehicle. An arm has a proximal section which is supported by the shaft for angular movement thereabout, and a free end section of the arm is located on the side opposite to the proximal section. A pulley is supported by the free end section of the arm for angular movement thereabout and is in contact with the belt. A plate element is provided which is fixedly mounted on the shaft. A plurality of rolling elements are arranged between the proximal section of the arm and the plate element. The rolling element rolls between the proximal section of the arm and the plate element to support the proximal section for angular movement. The arm is moved angularly by a spring about the shaft to bias the pulley toward the belt.
