ABSTRACT:
A tensioner acting on and allowing an endless transmission belt, stretched between a driving wheel and driven wheels supported on the body of an internal combustion engine, to run under a constant tension, wherein an oscillating lever supports a tension pulley pressed against a loosening side of the transmission belt and has a base end pivoted on the engine body, and an automatic adjuster connected to a tip end of the lever is supported on a case for a hydraulic pump of the engine. A spacer is interposed between contact portions of the oscillating lever and the engine body, and an outlet of the pump and an oil port of the adjuster are directly communicated. An adjusting screw is provided on the tip end of the oscillating lever and is operatively connected to the upper end of a plunger of the automatic adjuster. An auxiliary spring is further connected to the oscillating lever to assure the transmission belt of the constant tension, and the tension pulley supported on the oscillating lever is pressed against the transmission belt at a location close to the axis of an engine cylinder, that is, almost directly above the driving wheel, to thereby secure a sufficient space for installation of the automatic adjuster outside the pulley.
