ABSTRACT:
An auto-tensioner that inhibits the generation of heat in an insert bearing made of a synthetic resin. An outer shell of an arm member is swingably supported on an inner shaft of a base member through an insert bearing made of a synthetic resin, and a tension pulley carried at a tip end of the arm member, is brought into pressure contact with an endless belt by biasing the arm member with a spring. By subjecting an inner surface of the outer shell in sliding contact with an outer peripheral surface of the insert bearing, to shot peening prior to assembly, the arithmetically averaged roughness Ra and the maximum height Ry of inner peripheral surface are regulated into ranges of
