Abstract
An auto tensioner is supported on one side surface of a cylinder block (the outer surface of a front wall part) via a bracket. The auto tensioner includes: a tension pulley that is pressed against a belt; an arm that rotatably supports the tension pulley and is swingably supported to the bracket; and a hydraulic actuator that is supported by the arm and bracket to adjust the pressing force of the tension pulley to the belt using a predetermined position of the arm as a supporting point. The hydraulic actuator is disposed outside the water pump on the front wall part of the cylinder block.
