Claims

[Scope of utility model registration request]

An intermediate shaft is provided between the crankshaft and the camshaft, and a first
and a second chain, respectively, and these racks press first and second chain tensioner arms, whose ends are pivotally supported, to the passed first and second chains. In a chain tensioner for an internal combustion engine that applies a required tension to a second chain, a communication arm is engaged with the swinging ends of the first and second chain tensioner arms, and the communication arm is pressed by a tensioner adjuster. A chain tensioner for internal combustion engines that is characterized by
