168/123 ABSTRACT OF THE DISCLOSURE A V-type internal combustion engine having double overhead camshafts contains automatic mechanism for maintain- ing tension in the endless timing chain which drives the camshafts from the engine crankshaft. The two sides of the V-type engine are substantial duplicates. A tensioner body engages the slack side of the chain and is caused to move in a direction to tighten the chain to maintain desired chain tension. The tensioner body is operated by a curved arm member which is pivoted to a stationary support at a position in the dead space between the driven sprockets for the two camshafts. Resilient means acts on the curved arm member in a direction to tighten the tensioner body against the chain and a rocking member acted on by the resilient means prevents retrograde movement of the curved arm member, so that chain tension is maintained even when the chain stretches after a period of use.
