ABSTRACT:
An arrangement which can reduce the space between a tension pulley of an autotensioner and an engine block and thus reduce the installation space of an autotensioner. A sub-reservoir is provided at the side of a plunger of a hydraulic damper. The hydraulic damper is arranged between the tension pulley and the engine block so that it is received inside the outer periphery of the tension pulley with its plunger abutting a pin of an eccentric ring. It is thus possible to reduce the space between the tension pulley and the engine block.
