A belt autotensioner having a support shaft secured to a pulley support surface of a stationary member. A pulley support is rotatably supported on the support shaft at an offset position. A tension pulley is rotatably supported on the pulley support. A spring coupling member is mounted on the pulley support. A tension adjusting spring is provided to bias the pulley support in a belt stretching direction by exerting a spring force on the spring coupling member. A damper is provided to dampen vibrations transmitted from the belt to the pulley support through the tension pulley. At least one of the spring coupling member and the tension adjusting spring is mounted on the pulley support at a side remote from the stationary member.
